Zalakben,

Others can correct me if I am wrong, but I would say you must:

1.  Create a subclass of the Policy class (
http://ndnsim.net/2.1/doxygen/classnfd_1_1cs_1_1Policy.html)
     The Policy class is the class that the actual storage of the entries
can go into.  Check out
2.  Set your Cs to use your custom Policy class

Take a look at some of the policies provided, such as
http://ndnsim.net/2.1/doxygen/classnfd_1_1cs_1_1priority__fifo_1_1PriorityFifoPolicy.html
and http://ndnsim.net/2.1/doxygen/classnfd_1_1cs_1_1lru_1_1LruPolicy.html.

Pay close attention to the inherited virtual methods (member functions),
such as afterInsert.

Thanks,

John

Hi Alex,

Something seems strange. It does not matter whether I run my simulations
1000 seconds or 100,000 seconds ! In the former case a client issues around
40 Interests and in the latter case around 50 Interests. Does this make
sense ?

Thanks and regards.

Subject: [ndnSIM] Content Store - caching a couple weird objects?
Message-ID: <CAOD1O2mn7qVe-1X7vRRJLVKaGOy0iCiueuu==NcTKCNycOFr7g@mail.gmail.com>

Greetings all,

I'm playing around with some of the content store stuff at the moment and
have a couple questions.

Here are the relevant files to my questions:

*My primary simulation file:*
https://drive.google.com/open?id=0By9ufeKqmJYYN0dLMENXOVJjSlE

*My derived / customized policy class:*
https://drive.google.com/open?id=0By9ufeKqmJYYYUZOQUZFd21ORDA

*The output of the contents of Content Store:*
https://drive.google.com/open?id=0By9ufeKqmJYYTXdCMU1nN3lYeFU


Questions:

1.)  I figure the stuff with /prefix/.... in front of it is just randomized
/ pseudorandomly generated items just starting with /prefix.  But *what in
the world is *the other garbage being printed to the file?  Usually it's
something like /localhost/nfd/faces/enable-local/control/<random string>.

Is this some sort of setup information / link confirmation ACK or something
that the nodes send/receive?  Why is the CS caching it as if it were data?

2.)  Is there a significant advantage to using one of the NS_LOG or tracers
over using standard <fstream> library objects?

3.)  If I understand correctly, the *POLICY *is responsible for actually
caching the data?  I assume that's all handled with the doBeforeInsert and
the related virtual functions, like the policies that ndnSIM provides
(FIFO, LRU, etc.), correct?  The Content Store object itself seems to just
cache the *names* and not the actual data?

Thanks,

John

Hi John

1. With few exceptions, names beginning with /localhost/nfd belong to NFD
Management protocol
https://redmine.named-data.net/projects/nfd/wiki/Management . NFD
Management protocol is designed as an NDN application layer protocol, so
its packets show up as Interests and Data. CS caches them just as any other
Data.
2. Yes, NS_LOG allows one to enable and disable each logging component
individually via NS_LOG environ at runtime. For tracers, see
https://www.nsnam.org/docs/release/3.25/manual/html/tracing.html "tracing
motivation" and remember that NS_LOG will not work if ns-3 is compiled in
release mode.
3. No. CS itself caches the Data inside nfd::cs::Entry class and maintains
an index based on names. The argument passed to Policy APIs is the iterator
on CS's primary index, and Policy maintains a secondary index of those
iterators used for eviction. The reason for this separation is to support
different Policy types with standard C++ subclasses, rather than complex
compile-time templates (which was used in ndnSIM 1.0 and appears as "old
ContentStore").

Yours, Junxiao

Junxiao and Muhammad,

Thank you for your responses.  For a little more clarification regarding
where the actual data entries are stored:

When I look at cs.hpp:  *http://ndnsim.net/2.1/doxygen/cs_8hpp_source.html
<http://ndnsim.net/2.1/doxygen/cs_8hpp_source.html>*, and also the cs.cpp
file: *http://ndnsim.net/2.1/doxygen/cs_8cpp_source.html
<http://ndnsim.net/2.1/doxygen/cs_8cpp_source.html>*, I see the following:

In the Cs *HPP , *I see as data (private)*:*



*Table m_table;unique_ptr<Policy>
m_policy;ndn::util::signal::ScopedConnection m_beforeEvictConnection;*


So, a table (of entry names?), a smart pointer to the Policy (possibly with
a polymorphic object), and a signal - no data.

In the Cs *CPP*, I see nothing indicating insertion of data, except *through
*the policy.

On the contrary, when I look at one of the *Policy classes*, such as in the
FIFO policy (
http://ndnsim.net/2.1/doxygen/cs-policy-priority-fifo_8cpp_source.html) I
see use of what appears to be a map of entries, and an actual queue
(m_queue).

I'm just trying to wrap my head around what is going where.

I've been told, or given the impression, that if you want to change the
caching algorithm (cache replacement, caching) then the route to go is to
provide a subclass of the *Policy*, NOT the *Cs *itself.

Thanks a ton, everyone,

John

All -

As a follow up, I noticed that *emitSignal(beforeEvict, i); *is called in
both the LRU and Priority FIFO Policies.  Is *this *what tells the Cs to
remove the actual data, as the Policy subclass should also mimic / mirror
the removal from its "secondary index" (to quote Junxiao)?  I assume since
it's not just calling beforeEvict or something that it must be doing
something besides just that.

This may be the last major piece to my puzzle of figuring out what is going
on.

Thanks,

John

Sorry again:

Now I'm REALLY confused.  The note in the documentation for doBeforeErase
says:

NoteThis will not be invoked for an entry being evicted by policy.

Besides the policy, what else is responsible for evicting an item?  In the
LRU and Priority FIFO, it seems an emitSignal is called, which I assume is
supposed to trigger beforeErase, which calls doBeforeErase?  This is a
confusing spider web.  Hopefully you can help me untangle it.  :)

I'm headed to bed.  I'd really appreciate some clarification on these
issues.

Thanks so much for your patience, everyone,

John

Hello Everyone?

I want to get the matching faces based on the confirmed interest in the pit. And I noticed that the pit::FaceRecord::getFace maybe can help me.But I don't know how can I get into it and print the faces out.So can you give me some advices?And the similar question about the fib.How can I get the next hop faces based on the confirmed prefix?

 

Taanks for your reading.And best wishes to you.

Yours,

Runtong

Hi Carl

This is because nfd::Pit is not ?pending Interest table?, but ?Interest table?. NFD Interest table contains entries for both pending Interests and recently satisfied Interests.
Read NFD Developer?s Guide ?Interest table? section for more information.

Hi Junxiao,

Thanks! I see your point, but can I remove the expired ones? (at least for
certain prefix). Thank you in advance, for your guidance.

Hey,

The error suggests that you didn't get submodules (didn't use --recursive option to clone command).

Just do the following:

cd ndnSIM/ns-3/src/ndnSIM
git submodule update --init

This should fix it.

Hi Zhang,

"Usage" is not a parameter you can simply get.  You can only measure / estimate it.  One way to do this is to use ndn::L3Tracer (http://ndnsim.net/2.2/metric.html <http://ndnsim.net/2.2/metric.html>), which gives you an approximate value of usage for Interest, data, and other portions for each face.  For overall usage, you would just need to sum up those.

There are other ways to do this, but all of them include some sort of measurements.

If you just want to visually check, you can use the visualizer module (though it may not be trivial to make it work).

Subject: [ndnSIM] Content Store Caching/Replacement Policies
Message-ID: <CAOD1O2nq+VAeWj5skbhU9q=NYGQHx2mYHQh2M=rtLMN=jyofAg@mail.gmail.com>

ndnSIM friends,

Once again, I thank you all for your help and patience.

My questions:

1.)  In *cs-policy-lru.cpp*, the doBeforeErase function is as follows:

*void*
* LruPolicy::doBeforeErase(iterator i)*
* {*
*   m_queue.get<1>().erase(i);*
* }*

Note that it is removing an item from the queue, apparently.  However, I
was told this is just another copy of the table of iterators that the Cs
itself stores?

If this is so, how is this actually having any effect of the contents in
the Cs itself?

2.)  I noticed that there is an *emitSignal* when entries as evicted, and
it has beforeEvict as the first argument (in both LRU and Priority Fifo) -
what exactly is this signal emission doing?  Does this tell the Cs itself
to remove entries?

Thanks,

John

doBeforeErase doesn't affect the CS itself. It is being called just before removal of an entry from CS, which has been decided in some other way.

> 2.)  I noticed that there is an emitSignal when entries as evicted, and it has beforeEvict as the first argument (in both LRU and Priority Fifo) - what exactly is this signal emission doing?  Does this tell the Cs itself to remove entries?

Exactly. For LRU policy, this decision process happen on doAfterInsert: if the size of CS becomes larger than the limit, the policy selects an entry (using the policy-managed queue) and emit signal to indicate CS to remove the specified entry.   After that CS will do the job of preparing to remove, call doBeforeErase on the policy, and then actually remove the entry.

Alex

Thank you for the response!

So, to make sure I'm understanding this:. The Policy subclass maintains a
secondary table of iterators essentially (e.g., a queue) - when the Policy
implementation decides it's time for a specific entry to be removed, it
should remove it from its own table, but emit a signal to tell the Cs which
entry to remove as well.

Is this correct?

Thanks

John

Hi Guntur,

I'm glad of that!

As you may probably know by now, ndnSIM has a globalRoutingHelper, which is
not a real-time routing protocol. But for nlsr, thanks to Anil, it has
already been ported into ndnSIM. You can find the nlsr code here:
https://github.com/3rd-ndn-hackathon/ndnSIM-NLSR
And here you can find the doc on how to compile it:
https://github.com/3rd-ndn-hackathon/ndnSIM-NLSR/blob/master/PORTING.md

About OSPFN, it's better to quote Lixia from a couple of months ago
<http://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-August/002890.html>:

I dont think OSPFN was coded into ndnSIM, nor do we have such a plan.

Hi John

Alex already answered. There?s one mistake, though.

Policy::doBeforeErase will not be invoked when policy decides to evict an entry. It?s only intended to be invoked from Cs::erase (it?s not implemented because there?s no valid use case).

When Policy decides to evict an entry, it inform CS via beforeEvict signal to erase the entry from CS?s lookup index (the Table), and then deletes the entry?s iterator from Policy?s cleanup queue first. Since the eviction is decided by Policy, Policy already knows which iterator should be deleted from its cleanup queue, so there?s no need to CS to tell Policy which iterator should be deleted.
On the other hand, in the case of Cs::erase (when it?s implemented), the deletion decision comes from ?higher up? (an application or management utility), so the Policy needs to be told which iterator should be deleted from its cleanup queue.
 
Yours, Junxiao

I assume the premium account would be needed, but I was curious what your

Message-ID: <CAOD1O2mpuaiOoa+cVNNtp6r=6AmFLV-uNLkSjNiMcCpE=SMfZQ@mail.gmail.com>

ndnSIM friends,

At what point is it appropriate to print the contents of the CS?

I've tried putting some code to print its contents using iterators (e.g.,

for(auto it = theCS.begin(); it != theCS.end(); ++it)
{
    cout<<it->getName()<<endl;
}

But this doesn't appear to do anything.  I'm currently putting the code
after Simulation::Run() and before Simulation::Destroy();

Is there somewhere else I should be putting it?  I assumed it would print
out all the remaining entries by the time the simulation was done running.
I was apparently wrong.

Note:  I'm not doing anything special in my custom Policy (e.g., I'm not
tracking a secondary table of contents yet.)  - but does this even have
anything to do with it?  I assume that items are put in the content store
regardless.

Ideas?

Thanks,

John

Hi John,

I would suggest you either use the NS3 logging statements (e.g., NS_LOG_FUNCTION, NS_LOG_INFO) or the cerr to print out the contents of the CS.

Hope that this helps,

Spyros,

Thanks for the reply.  However I think the problems seems to be that there
is apparently nothing in the CS when I go to print it.

It never enters my loops - so it will never print out the information
regardless of the printing technique.

My code for custom policy does detect content being inserted (e.g.,
doAfterInsert is called) and the limit on both Cs and my custom Policy are
set to 10.  So I assume it's being added.  So why is it empty by the time I
print it out?

Thanks

JPB

Dear ndnSim friends,

I am running a scenario. After running for a while I have the following 
error:

*assert failed. cond="i->second == ev.impl", 
file=../src/core/model/map-scheduler.cc, line=108***

*terminate called without an active exception
*
what does this error means? How can I correct it?

Thanks

Hi everyone,

The ndnSIM simulator time is fixed. When receiving data or interest packet,
I edit the procedure about onData() and onInterest(). I think it should be
difference time, But the simulator time is always the same. Where can I
change the time to more real time in ndnSIM. Is the code in Timer on ns3?

Hi,

the simulator uses simulation time. If you want to get the real time, you might want to use something like this ?hack":

Have you recently upgraded the installed version of boost libraries?  The error suggest a mismatch between headers and binaries of the boost libraries.

Hi Junior,

While I cannot say for sure, it seem to be related to memory exhaustion.  You can try to observe whether the memory usage for the scenario process is growing or not during the simulation.

On another note.  The error also indicates that you're using the debug build of the simulator to run your scenario.  The debug is much slower (~10 times or so) than running in the optimized mode (`./waf configure -d optimized`).

Dear all ndn-sim user


I want to add some data  like "01010101" on data packet

And then , for consumer , have to check the data "01010101" right or not.

there will be a channel coding on it.

so I dont know how to add to the packet.

I know the ns2 how to add , but the ns3 ndn-sim i cant.

can someone help me?

Hi JianDe,

Here's how I added a string data to a Data packet for a Content producer 
to send:

#include "../ndn-cxx/src/encoding/block-helpers.hpp"
#include "../ndn-cxx/src/encoding/tlv.hpp"
auto data = make_shared<Data>();
const std::string str = "01010101";
data->setContent(::ndn::encoding::makeStringBlock(::ndn::tlv::Content, 
str));


The way for a Consumer to check the data it received is:

data->getContent().value();


I hope this helps!!

Best regards,
Yoshimichi Nakatsuka

Subject: [ndnSIM] example custom caching error
Message-ID: <CAGPE7m+xw9Sr3LMVqouOHQDB6P2U7bRnFUCoUqgaZvT5fXZ=nA@mail.gmail.com>

Hi All,

So, Im quite new to ndnsim and have been trying out the example custom
caching policy as given in the demo ppt.

So far I have

- placed the policy traits, example_policy.h into scenario/extensions/
folder

- placed the content store implementation of the policy
cs-with-example-policy.cc(code exactly as given in the ppt) in the same
folder, ie, scenario/extensions/ folder

- have added the following lines into
src/ndnSIM/model/cs/content-store-impl.cpp

template class ContentStoreImpl<example_policy_traits>
NS_OBJECT_ENSURE_REGISTERED_TEMP(ContentStoreImpl,example_policy_traits);


- and finally in my simulation scenario, i refer to this policy using

ndnHelper.setOldContentStore("ns3::ndn::cs::Example");

But when I run this scenario, it just throws up a bunch of errors.
Am I missing some steps?,Where could I have gone wrong?

Sorry if my problem is too obvious, I'am a beginner here.

Thank you!

Hi All,

I got it to work. I was actually using an old version of the content

Thanks!

Just go to the NLSR folder and do:

./waf configure

./waf

cp build/nsync/sync-state.pb.*    ../../../build/ns3/ndnSIM/NLSR/nsync/

(Assuming you are in NLSR folder under ns-3/src/ndnSIM).


Then go back to the ns-3 folder and continue:

./waf

Hello Sepehr,

For now, follow the steps as mentioned by Ashlesh. This is a one time
workaround (till the time you make next ./waf distclean) to get around this
problem.

Additionally, patch the attached diff to your ns-3/wscript file and then
(re) configure the nlsr into ndnSIM using following command.

./waf configure --enable-examples --enable-nlsr


After these things are done, you can start building the ndnSIM.

/anil.

Message-ID: <CALrx89NkrevUDhhMXn602XObLq5PC=cL-wEg9mxQMpW4nTKHgQ@mail.gmail.com>

Greetings all,

I am trying to create monitoring node or entity so that I can get the
monitoring info of other nodes (like PIT, CS, FIB) on that node. I gone
through some example in ndnsim like (ndn-tree-tracers.cpp -
*http://ndnsim.net/2.1/metric.html
<http://ndnsim.net/2.1/metric.html>). *The tracers saves statistical
information in .txt format can this be used as monitoring information or
are there other methods available to do so??

>From the examples on tracers I made changes in topology and added one more
node for monitoring purpose. Now how can I transfer the different tables
like PIT and content storage of all the network to this monitoring node?.

I wanted to know how to give a particular node a monitoring capabilities
(like there are producers and consumers are there any monitors which are
mentioned in doxygen of ndnsim?)


Please guide me

Regards,
Aniket Yeole

Hello everyone and Junxiao,

    I am using add-delays-tracer monitoring the interest sent out of the app and trace its hops and delays, now app-delay-trace offers only time and node information and so on as output, but I want to add another field "Interest name" of the corresponding request entry, I have studied the code of app-delays-trace.cpp and hpp and found only output function there, but I can't find where to add the field of the monitoring data, so I am sincerely asking you for your kindful help! I would appreciate it if anyone could generously help me out~

Hi,

you could create your own applications (producers and consumers). The monitoring node can act as a consumer that sends Interests and fetches the data of your interest from the rest of the nodes (producers). After that, you will have to decode the data content and store it in the way that you like.

Hope that this helps,

Hi,

you will have to add trace sources like the following:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/model/ndn-l3-protocol.cpp#L78-L106
https://github.com/named-data-ndnSIM/ndnSIM/blob/master/model/ndn-l3-protocol.hpp#L208-L220

You can take a look at this commit, where I added the appropriate tracing functionality for network NACKs:

Beyond that, you can use existing policies as an example.

Hi Fatemeh,

I'm assuming you're using the "old"-style CS policy.  Take a look at 'insert' method for the policy (e.g., line 106-125 in util/trie/random-policy.hpp).  What you need is to add a random decision to return false and avoid any other actions in this function: if insert returns false, the data packet will not be inserted.

Hi Sepehr,

I have committed couple of fixes for this issue. Can you please update your
git repo and do a clean build again.

Configure using this --

./waf configure --enable-examples --enable-nlsr

Hi,everyone:

    I want to use the WaypointMobilityModel.But in the path
"ns-3/src/mobility/examples", it only provides examples of
RandomxxxMobilityModel. Who can give me an example of the WaypointMobilityModel
usage?

    Thanks for your help!

The built-in tracers produce a simple txt files that list measurements as described in http://ndnsim.net/2.3/metric.html <http://ndnsim.net/2.3/metric.html>. You can also add your own measurements in your own format.  How to visualize the data is really up to you and you can use any tool, including R, python, Excel, etc.

Subject: [ndnSIM] Get or fine Node name at fowarder.cpp during simulation
Message-ID: <CAP2g9KOV8xUA_0m+dcP8WafuorBf=fUYxuriNNoHAfNb7BzqDA@mail.gmail.com>

Hi.

I like to add new FIB entry at *fowarder.cpp*, "*onIncomingData*" Method
during simulation.
I know that I can use "*FibHelper::AddRoute*", for Example :

*AddRoute (const std::string &nodeName, const Name &prefix, uint32_t
faceId, int32_t metric)*

For  "prefix"  I can use    *data.getName()*.
For  "faceId"  I can use   * inFace.getId()*.
For  "metric"  I can use    *0 or any other value*.
But I don?t know what should I Use for "*nodeName*".

How could I get or fine Node name at fowarder.cpp during simulation?

Best regards.

Shahram,

If you give *name *to nodes, through AnnotatedTopologyReader,
scenarioHelper or otherwise, you can use the helper with the signature you
mentioned. If you take a look at its implementation
<http://ndnsim.net/2.3/doxygen/ndn-fib-helper_8cpp_source.html#l00117> I
guess you will find a clue how to use it.

Regards,
Sabet

Message-ID: <CAOD1O2ntur15JxqRpsVjNRK0w2LFDfOn7yK8O1Uq5pvQemXQXw@mail.gmail.com>

Greetings all,

There's no "upgrade" command of any sort, correct?  I assume we just have
to follow the installation steps on the site as if we were doing a fresh
install?  Do we need to uninstall anything first?

I stuck with 2.1 and have been a little intimidated to upgrade, but it may
be time.

Thoughts?  Instructions?

Thanks,

John

Hi John

Just deploy another VM and install everything from scratch.

Caution: Unlike ns-3, ndnSIM does not maintain backwards compatibility
across versions. Your scenarios and patches to the simulator itself will
need non-trivial porting work.
As long as you keep ndnSIM inside a VM, there should be no security concern
that requires you to upgrade. Thus, you can weigh between the benefit of
getting new features and bugfixes and the workload of porting the scenarios
and patches.

Yours, Junxiao

ndnSIM friends,

I've been working on creating a custom strategy, and I can't seem to figure
out why it's generating the errors that it is.


Here are the related files:

*The errors:*

*Test file using the strategy*

Any help would be appreciated.

ndnSIM folks,

Okay, so I made a (really poor) workaround - I added #include
"PolularityStrategy.cpp" to the bottom of the .hpp file...  It appears that
the .waf system doesn't look for .cpp files in the example or
subdirectories to compile?  I'm very confused by that.

Regardless, I got it to compile, but I have an issue now:

cout<< (or std::cout) is not printing anything.  I've tried it in the
constructor...  I've tried it in afterReceiveInterest...  nothing.

Any ideas about why this might be the case?

Thanks,

John

Hi John,

From the error I see that you're writing your simulation scenario in the 'examples' folder of ndnSIM.  While you certainly can do that, I would highly recommend to use the skeleton (https://github.com/named-data-ndnSIM/scenario-template <https://github.com/named-data-ndnSIM/scenario-template>).  It will speed up your compilation times and the default build script has more straightforward assumptions on where the code is.

The error simply tells that you need to properly link your strategy to the scenario.  Given I don't know where you put your strategy code, I cannot tell more.  With the skeleton scenario, you simply need to put it in extensions/ folder.  If you prefer using examples/ folder, then you need to create a folder, whose name is exactly as your scenario name, but without .cpp extension and put the code there.  Alternatively, you need to modify wscript in examples folder and add all necessary dependencies for your scenario.

If you installed boost libraries from source, then you have to make sure you don't have boost development packages installed (in particular, you should not have /usr/include/boost folder).  Otherwise, there will interfere and you will not be able to compile.

Alex,

Do you mean create a top level directory with the name of the scenario, and
then use the directory structure of the template you provided and ndnSIM
will do the rest?

Next question would be:. Where do we put the top level of the templated
directory structure you suggest?

Thanks

John

Subject: [ndnSIM] Evaluation Model
Message-ID: <CADm-vn0fhmhDgCion_r3_Xt0XduKte6WRLgWE0OyeBaf-AcG7w@mail.gmail.com>

Hi my dear researchers,

Now, I am in evaluation part of my model. I got many errors when analysis
the results which are:

1- I was just trying to calculate the PIT size for NDN router using Abiline
topology. However, I found the result is the same for each routers. It's
normal. Setting PIT size is 1000, and consumer frequency stringvalue is
6000 interests a second.

2- In the same scenario, the app-delay-tracer file not generated. While
when decrease the consumer frequency stringvalue less than 1000 is
generated.

3- In app-delay-tracer file, how to calculate the average delay for hole
scenario since we are seeing in this file there is value for each
millisecond.

4- How can get the average PIT entries Lifetime and the entry Maximum
Lifetime for each router. It is seen when I used GetMaxPitEntryLisetime(),
gave me the result like this " +0.0ns". I don't understand what is mean?

5- I read in some paper the metrics namely Time-to-Completion, which is
meant the time it takes for content items to completely arrive at the
subscriber. How to calculate this metrics.

*My Regards,*

If you use template, follow the description in the README.  This template should be placed anywhere outside NS-3/ndnSIM and will simply use the installed NS-3 to link to.

If you not using template, take a look for ndn-load-balancer, ndn-custom-apps, ndn-cxx-simple, ndn-simple-with-content-freshness, ndn-simple-for-nrt-helper examples organization (i.e., .cpp file with main function and directory with code that is linked to the scenario).

To get hold of Ptr<Node>, you can use the following

Ptr<ns3::Node> node = item->payload()->GetContentStore()->template GetObject<ns3::Node>();

If you have associated name with the node (e.g., by using the AnnotatedTopologyReader), then you can get hold of it using Names API:

std::string name = Names::FindName(node)

Hi Sravya,

Which version of ndnSIM you're using?  The example code for the latest ndnSIM doesn't have this include nor this tracer exists (its function superseded by L3RateTracer).  The old version of ndnSIM also didn't have this include, it was including <ns3/ndnSIM/utils/tracers/ndn-l3-aggregate-tracer.h>.

  how can i realize a consumer APP that after client receive the data for the previous interest, than client can send the next interest to the net, rather than send interest depend on sending rate.
  i.e. after client send a interest, no matter how long client have to wait for the correspond data, it can not send next interest until receive the data.

If you're using ndnSIM version 2, you need to look at the corresponding documentation.  As the quoted URL suggests, it is about ndnSIM 1.0.

Depending on which exactly version you're using, the documentation is either http://ndnsim.net/2.3/ <http://ndnsim.net/2.3/>, http://ndnsim.net/2.2/ <http://ndnsim.net/2.2/>, http://ndnsim.net/2.1/ <http://ndnsim.net/2.1/>, or http://ndnsim.net/2.0/ <http://ndnsim.net/2.0/>   

> when i try to modify source code of fw, what .cpp or .h files do i need to modify? any one who can tell me which related files i have to modify if i try to modify on of fw.
If you're working with ndnSIM 2+, then the starting point would be to read the relevant sections NFD Developer's Guide.  After that, the examples include several custom strategies, where you can get an idea what to do.
> on the web site, i got that there is three color which is green & red & yellow, to indicate the status of the face, and these faces which carry the color status will be rank, where can i get the file?
This is the strategy existed in ndnSIM 1.0 and doesn't exist in 2+.  Though, it should be straightforward to (re-)implement it.

What you describing is not really achievable, at least not in the way that will be straightforward.  NS-3 is discrete event simulator, where many events are "scheduled" to be executed.  The process of sending interest involves multiple events, each of them starting with the simulator's event queue.   You can probably debug trace all of these events, but I doubt it would be much useful.

If you need to do something with FIB entry, just look it up inside your beforeSatisfyInterest implementation.  The provided API allows you to quickly find FIB, supplying the pitEntry.

Hi Kengo,

There are a few ways of achieving this.  The simplest one is to modify the existing Produce application to remove the assumption that all requested data exist and only reply the Interests of your choice.

A little bit more complex, but future proof, is to write a second producer applications the implements your behavior.  We will be really happy to merge this code into the ndnSIM.

You need to ensure that ndn-load-balancer.cpp is actually linked to your scenario.  This is similar to my recent answer to John: if you use scenario template, then it is a matter of putting ndn-load-balancer.cpp in the extensions folder.  If you are using examples or scratch folder, then you must follow the conventions of the build system (take a look into examples/wscript for more details).

My guess that you're using ndnSIM 1 and by "setting PIT size" you mean setting the limit on the number of PIT entries.  

If you set replacement policy for PIT as Lru, then I can see why there is nothing in app-delay-tracer file, as no interests will be ever satisfied: the new ones simply remove old state and even data packet comes back, it cannot be returned to the consumer.


> 3- In app-delay-tracer file, how to calculate the average delay for hole scenario since we are seeing in this file there is value for each millisecond.

I'm a bit confused with your question. AppDelayTracers gives a delay for each of the requested data.  If you want average across all different data pieces, just calculate it...

>

You need to give more context for this.  What is GetMaxPitEntryLifetime() ?

> 5- I read in some paper the metrics namely Time-to-Completion, which is meant the time it takes for content items to completely arrive at the subscriber. How to calculate this metrics.

I cannot answer this question.  It is really up to you how to define "completion" in your scenario.

Hi Spyros,

Thank you so much for your help! I have been studying how to modify and enhance the trace source in ns-3 in the past two days, thanks to your advice and ns-3 turorial as well as post in https://groups.google.com/forum/#!topic/ns-3-users/xty2I8JV3_c , I am able to understand the mechanism of tracing system of ns-3 and realise my own trace source and trace sink! I'd like to share the material with everyone else in the mailing list to help them in terms of the same kind of questions.

Thank you again for your help!

Yours,
Sincerely

Hi,

you will have to add trace sources like the following:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/model/ndn-l3-protocol.cpp#L78-L106
https://github.com/named-data-ndnSIM/ndnSIM/blob/master/model/ndn-l3-protocol.hpp#L208-L220

You can take a look at this commit, where I added the appropriate tracing functionality for network NACKs:

Alex,

Thanks for that information.  Truly, very helpful.

Secondly, I was eventually able to get it to compile, but nothing is being
printed out - I have cout statements in the ctor and the
afterReceiveInterest.  The CS is receiving data, but the Strategy doesn't
seem to be acknowledging the existence of incoming Interest packets.

Ideas?

Thanks,

John

Junxiao,

I subclassed MulticastStrategy.  The instructions on the site say to create
your own custom strategy you subclass Strategy.  I suspect it works that
way with one of the derived classes from Strategy also.

Thanks

In addition to subclassing, the strategy needs to be "registered" with the `NFD_REGISTER_STRATEGY(YourStrategyClassName);` macro and choose to use this strategy for the namespace of your choice (e.g., using StrategyChoiceHelper http://ndnsim.net/2.3/helpers.html#forwarding-strategy <http://ndnsim.net/2.3/helpers.html#forwarding-strategy>).

Sorry. Missed that. I see that you also have properly used StrategyChoiceHelper.  One thing that I would change is either explicitly configure multicast strategy on all nodes except node 2, or use a more specific prefix for node 2.  The behavior is not necessarily defined, given the order of execution should be sequential, but may not be guaranteed.

Alex,

Thanks again for the information.  Perhaps I should mention my goal in this
isn't to actually change the forwarding strategy itself.

I want to access / record the Interests as they come in.  As far as I can
tell, Strategy is the only place there is a virtual method that (should) be
called automatically when an Interest arrives.

Is this correct?

Thanks

John

Kengo,

As Alex said, you can modify the existing producer application into a new
one. A very simple one could be an application in which there are two
folders /existing and /nonExisting. In Application::OnInterest, the
application checks whether incoming interests are looking for something
under /existing, so it answers. Otherwise there will be no data back.

Alex,

About the a little bit more complex one, you mean an application which has
created a defined number of Data packets before? At the time of starting
maybe? Or more like a real we application?

Regards,
Sabet

Hi Spyridon and ndnsim team

Thankyou for the advise but can you elaborate it more, the process of
sending Interest and fetch the data from other nodes ??
and how to decode the data content ?

Can you share some small example for reference or something that I can
refer ?

Regards,

Hi,

this is the way to decode a data packet:

https://github.com/named-data-ndnSIM/ndn-cxx/blob/ndn-cxx-0.3.4-ndnSIM/src/data.cpp#L135

These are the callbacks to invoke in order to send Interest and Data packets:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-consumer.cpp#L202
https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp#L131

Hope that this helps,

Hello, NDNSim users.

I'm here studying NDN interactions with NDNSim, and i was trying to setup
the cache mode for all nodes and collect data from them to plot in a
graphical and easy viewer of the performance of each kind of cache
available in NDNsim.

Unfortunatly when i use CS Tracker, i must use the oldsetcontentstore that
appears to not work as well.   Could someone help me in this case?

Best regards,

Message-ID: <CAEv4q0Za2qidNFXXFaUxPP5j1i9pT_o367pX=c8s10a5qUdcMg@mail.gmail.com>

Dear NDN researchers,


Thank you for all the helps you have given me so far.
I have made breakthroughs in my simulation modification so far.
However, I am struggling with the simulation of a certain scenario, hybrid
of wired nodes and wireless nodes.
There is a gateway in the middle of between these hybrids.
I am curious whether this hybrid scenario can be implemented with ndnSIM
ver 2.
Is there any library to implement a gateway at ndnSIM? Shall I just make it
for myself?

Best wishes,

inchan Hwang

It's mostly your call how to do it. As an example, take a look at

http://ndnsim.net/2.3/doxygen/classns3_1_1ndn_1_1Consumer.html

There is a OnData method that is called every time new Data arrives. You
may schedule your application sending next Interest there. As Alex pointed
out, you may update existing consumer apps(ConsumerCbr, ConsumerBatch, etc)
or write a new one familiar to existing ones but having your own OnData
method implemented, which behaves as you want. Indeed it should be simple.
Just take a look at existing apps. I'm sure you will find what you're
looking for.

Message-ID: <CALKy0XYikPk4pK1D8W_dX8bMgCV=OhwoqwwttE9ucG=T6=E90w@mail.gmail.com>

Hi all,

I am new to ndnsim. I was working with the example
*ndn-tree-tracers.cpp*. While
running the simulation example (ndn-tree-tracers.cpp) I got some error
which I am unable to resolve. I used different Consumer application instead
of *ConsumerCbr* which resulted in following error.

/*

I replaced following line

With
ndn::AppHelper consumerHelper("ns3::ndn::Consumer");

Please guide me about how I can use the *ndn-conumer.cpp* as I wanted to
make changes in Interest Packet and its following Data packet for it using
this ndn-conumer.cpp?

Dear ndnSIM users

I need to install the new version of ndnSIM which the NLSR protocol in
ported in it and is in this repository :
https://github.com/3rd-ndn-hackathon/ndnSIM-NLSR

when I enter command ./waf , this error occurs :

/home/mahsa/ndnSIM/ns-3/src/ndnSIM/NLSR/nsync/sync-state.proto: File does
not reside within any path specified using --proto_path (or -I).  You must
specify a --proto_path which encompasses this file.  Note that the
proto_path must be an exact prefix of the .proto file names -- protoc is
too dumb to figure out when two paths (e.g. absolute and relative) are
equivalent (it's harder than you think).

I searched into the internet but I did not find any solution.
I really appreciate your help and attention.

Hi,

the Consumer class is supposed to be used as the base class for derived consumer classes that actually control the Interest/Data sending rate. It is not supposed to be used directly in simulation scenarios.

You can create your own consumer class that derives from the base consumer class and implement your own logic.

Hope that this helps,

yes I have followed these instructions, although I copied nsync/
sync-state.pb.cc and nsync/sync-state.pb.h from NLSR/build/nsync to the
specified folder in ndnSIM.

the complete error is this :

Hi Mahsa,

Can you please update your git repo ndnSIM-NLSR git repo and do a clean
build again? It should work now. I have pushed one change.

/anil.

Dear all,

How one can calculate the overhead for updating the shortest paths, with
the Best-route strategy?

Thanks,
C.

Hi Carl

The best route strategy follows the routing costs in the FIB, which is
controlled by the routing protocol.
Thus, the overhead of updating shortest paths is the overhead of running a
routing protocol, plus a little bit of CPU usage within NFD management.

Yours, Junxiao

Hi Junxiao,

I see, but is there a way to calculate it exactly? (communication overhead)

Thanks,
C

Hi Carl

Communication overhead can be calculated by running a routing protocol such
as NLSR (there is an ndnSIM port for it), and count how many packets are
transmitted by it.

Yours, Junxiao

Dear Mr.Jangam

I really appreciate your quick help, I did as you said and that error did
 not show up.
now in compiling NLSR code, this error ocurs :

In file included from ../src/ndnSIM/NLSR/src/nlsr.hpp:38:0,
                 from ../src/ndnSIM/NLSR/src/route/map.cpp:26:
../src/ndnSIM/NLSR/src/hello-protocol.hpp: In constructor
?nlsr::HelloProtocol::HelloProtocol(nlsr::Nlsr&,
ndn::util::scheduler::Scheduler&)?:
../src/ndnSIM/NLSR/src/hello-protocol.hpp:49:5: error: ?m_outInterest? was
not declared in this scope
     m_outInterest = 0;
     ^
../src/ndnSIM/NLSR/src/hello-protocol.hpp:50:5: error: ?m_inData? was not
declared in this scope
     m_inData = 0;

I checked the hello-Protocol.hpp source code but unfortunately I did not
find why this happens.

Hi Mahsa,

Perhaps something wrong with your workspace/view or configuration. I did a
fresh clone of nlsrSIM and it all compiled fine. I suspect most likely you
have not enabled the NLSR at configure time. May I suggest you to do
everything from fresh? Do the following.

1. ./waf distclean
2. ./waf configure --enable-examples --enable-nlsr
3. ./waf

Note that '--enable-nlsr' enables the nlsr simulation specific changes
added to the NLSR and above code is part of it. I will look into this and
fix the problem. For now follow above steps once again.

Thanks,
/anil.

Dear Mr.Jangam

I appreciate your help and attention, --enable-nlsr solved my problem,
thank you for your great help.
Now the ./waf command completed, but is there a way to get sure that
ndnSIM-NLSR is correctly installed?
when I run this command :

perl nlsr-experiment.pl
/home/mahsa/ndnSIM-NLSR/ns-3/src/ndnSIM/examples/ndn-nlsr-conf/5_node_router.brite
ls
 in  folder : /ndnSIM-NLSR/ns-3/src/ndnSIM$  the output is like this :

Waf: Entering directory `/home/mahsa/ndnSIM-NLSR/ns-3/build'
program 'ndn-nlsr-confgen' not found; available programs are: []
Waf: Entering directory `/home/mahsa/ndnSIM-NLSR/ns-3/build'
program 'ndn-nlsr-simple' not found; available programs are: []

Do I run the command in a wrong way?

Thank you for this much of help.

Hi Mahsa,

I believe the way you are using the perl script is NOT correct. Use it as
follows from within ndnSIM folder and let me know (I have tested it).

perl nlsr-experiment.pl 5_node_router.brite ls

Follow the steps here:
https://github.com/3rd-ndn-hackathon/ndnSIM-NLSR/blob/master/PORTING.md


Once the the build is complete, all the binaries are built and available in
the ns-3/build folder. To be precise, you should find the above missing
files in folder 'ndnSIM-NLSR/ns-3/build/src/ndnSIM/examples'. Look for
'ns3-dev-ndn-nlsr-confgen-debug' and 'ns3-dev-ndn-nlsr-simple-debug'.

/anil.

Subject: [ndnSIM] ndn cache replace policy
Message-ID: <585BEF23.8090601@mail.ustc.edu.cn>


Hello :
  I am trying to realize a cache replacement policy on ndnSIM .The new policy is based on lfu policy.  According to the api document I found that
 1)  The ns3::ndn::ContentStore has realized lfu policy , but the code is quite complex,including trie.hpp?tire-with-policy.hpp?lfu-policy.hpp and so on
2)  The nfd::cs::Cs  hasn't realized lfu policy,but the code seems easier.
So which kind of contentstore is easier to realize my policy,   ns3::ndn::ContentStore or nfd::cs::Cs  ?And how to  realize a cache replacement policy,Think you very much!

Hi,

personally, I feel it would be easier for you to use the CS of NFD. 

You will have to create your own class that will derive from the Policy class of NFD.

Hope that this helps.

Hi,

I am not aware of the exact parameters of your simulation scenario, but most probably this has to do with either the simulation topology itself or the topology parameters (bandwidth, queue length at each node and delay). Another reason could be the rate that the consumers send their Interests.

Greetings,

By no means do I claim to be an expert in this simulator (yet!), but I have
been taking and trying to organize notes about using it.

Please see page 9 in the PDF on my Google Drive:

*https://drive.google.com/open?id=0By9ufeKqmJYYTnZVYnBlNktvMHc
<https://drive.google.com/open?id=0By9ufeKqmJYYTnZVYnBlNktvMHc>*

I hope to eventually more fully organize this document after adding a
significant amount more, adding a table of contents, etc.

But hopefully this helps some people even in its current, very unedited and
minimal state.

Thanks,

John

Subject: [ndnSIM] Simulation of wired and wireless network.
Message-ID: <CAEv4q0YEG6hqrDoZ0XPegxoHViBE-WEVxK7=8yZ=kYE_98y3SQ@mail.gmail.com>

Dear NDN researchers,

I have tried to simulate the hybrid network of wired and wireless ones.

But first of all, I have found a very strange bug with ndnSIM 2.1.

In the example, I uploaded.
https://github.com/NDNUtils/NDNSIM/blob/master/src/ndnSIM/examples/ndniotWireless10Pros4Cons2min.cpp#L275
https://github.com/NDNUtils/NDNSIM/blob/master/src/ndnSIM/examples/ndniotWireless10Pros4Cons2min.cpp#L304

Over there, WiFi scenario works only when I install 2 wifi net device
containers. If I install only one netdevice container.
Wireless communication never happen.

With the strange example code I have made, it works fine. However, it is a
very weird operation. If any of you know
why this happens, I am glad to hear some explanations.

In this manner, I was installing both p2p wire and wifi stacks on a single
node to mimic a gateway.
The code is
https://github.com/NDNUtils/NDNSIM/blob/master/src/ndnSIM/examples/ndniotWireWIFI3Pros1Con.cpp#L299-L304

However, as soon as I put wifi stack after I add p2p. Simulation goes
silent, it does not give any error messages but never work.

My questions are below.
Is it appropriate to mimic a gateway like this?
Is it possible to put p2p and wifi stack over a single node over ndnSIM?

Best wishes,

inchan Hwang

thanks for your reply, maybe i do not explain my simulation scenario, as you can see bellow:


                                  producer1
                                  /
                                /
consumer--------node1-----------producer2
                               \
                                \
                                 \
                                 producer3


node1 send interests to producer1 or 2 or 3 randomly, consumer send interest only one per second, node1 to three producers has same parameters, for consumer, i think it's delay time should be same for every request, but it sames not as what i expected, do you know the reason?
By the way, any one who konw how can i control the capability of a producer?

I do not see that being a bug of ndnSIM. Most probably, it has to do with the simulation parameters and specifically with the parameters of the selected NS3 wifi model, the model of the propagation losses or/and the selected mobility pattern. You can check the NS3 documentation for more details.

Yes, that should be possible.

Yes, that should be possible too as long as you tune the parameters of each model in the right way. 

Unfortunately, I am not aware of the specifics of the NS3 wifi and mobility models. I would suggest you send an email to the NS3 mailing list.

Have you run `./waf clean` (or `./waf distclean`) prior to that?  Otherwise, the build system may not have properly recompiled the files.

Hi Sepehr

I guess #include finds Boost 1.62, but linker is trying to link to a
different version of Boost .so libraries.
Don't ever manually delete any file in /usr. Uninstall the relevant
packages instead.

Also, I always recommend to start with a clean VM, and only install Boost
from Ubuntu packages. This avoids most problems.

Yours, Junxiao

  I'm a little confused of how can i set the capability of producer in ndnSIM? I means the producer in reality it's capability is limited, if there is too much interest coming, the producer will break down, whether can i set the number of this limit?
  Another thing is if i can let network situation has a obvious fluctuations and different interests will be send to different producer(assume there hava at least 2 producers), interests' delivery rely on network situation rather than hopcount or random strategy?
  Thanks to  all!

Hi,

this is a feature that you will have to implement by yourself (it is not offered automatically by ndnSIM). Specifically, you will have to implement this feature as a part of the producer application:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp
https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.hpp

Hope that this helps,

Hi
   Spyros and John,Thank you for your sharing and suggestion  .It is quite helpful for me,as I have spent much time to study  ns3::ndn::ContentStore .
   If I want to refresh all the CS table every 1 second, Can you give me some advice ? It seems that the NDNSim api document has no related content. Should I study the NS-3 source code.Thank you very much!
   Merry Christmas

Greetings,


By no means do I claim to be an expert in this simulator (yet!), but I have been taking and trying to organize notes about using it.


Please see page 9 in the attached PDF.  I hope to eventually more fully organize this document after adding a significant amount more, adding a table of contents, etc.


But hopefully this helps some people even in its current, very unedited and minimal state.


Thanks,


John

Hi,


personally, I feel it would be easier for you to use the CS of NFD. 


You will have to create your own class that will derive from the Policy class of NFD.


Hope that this helps.

Hello :
  I am trying to realize a cache replacement policy on ndnSIM .The new policy is based on lfu policy.  According to the api document I found that
 1)  The ns3::ndn::ContentStore has realized lfu policy , but the code is quite complex,including trie.hpp?tire-with-policy.hpp?lfu-policy.hpp and so on
2)  The nfd::cs::Cs  hasn't realized lfu policy,but the code seems easier.
So which kind of contentstore is easier to realize my policy,   ns3::ndn::ContentStore or nfd::cs::Cs  ?And how to  realize a cache replacement policy,Think you very much!

Hi Sepehr

To ensure others can reproduce your issue, can you start with a standard
template
vagrant init ubuntu/trusty64
vagrant up
vagrant ssh
and then post every command you have executed within the VM up to where you
get the error?

Yours, Junxiao

Hi everybody,

Are there any easy approaches to attaching arbitrary information to
Interest/Data packet, so that forwarding strategy can read?

As the information may change hop-by-hop, it is improper to be put in Name.
One possible solution is customized tag. How much effort to create one?

Thanks,

Message-ID: <CADm-vn3Nh22=3UN_U-RUxTnNPpAL9KLRAM+6O6FVyBfh3Q1tig@mail.gmail.com>

Hello everyone in this amazing and helpful group,

I have these questions:

First, what is the default size of Interest packet?

Second, how can Increase and decrease the Interest packet size?

Third, the instructing here:
ndnHelper.SetPit ("ns3::ndn::pit::Persistent::AggregateStats", "MaxSize",
"10000");

What is mean "10000"?

Fourth, Fourth, can we use both two instructing in one scenario as follows:

consumerHelper.SetAttribute ("Frequency", StringValue("10000"));
consumerHelper.SetAttribute ("Randomize", StringValue ("uniform"));

What are effecting on the scenario ?


Kind regards.
  Raaid

Subject: [ndnSIM] Add a tag to packet
Message-ID: <CAPDQcDZZ1jAcW-xkZ-vvV-DeuMy3oyRC8BQHHxhrYpWSr3Wqcw@mail.gmail.com>

Hi,

I want to access the packet in the cache policy (for example
random-policy.hpp ) for adding  a tag to it. I create a new tag to record
node-Id and If the node cache the content, it will add this tag to the
content packet. In the *insert()* method, I have the following code: "Ptr<const
Packet> pkt = item->payload()->GetPacket ();" to access packet and
then "pkt->AddPacketTag
(tag_id); " but I get this error:
*error: ?class
ns3::ndn::cs::EntryImpl<ns3::ndn::cs::ContentStoreImpl<ns3::ndn::ndnSIM::rand2_policy_traits>
>? has no member named ?GetPacket?*

I also try the following code:

auto data = item->payload()->GetData(); auto dataTag = data-> getTag
<ns3::ndn::Ns3PacketTag> (); bool hasTag =
dataTag->getPacket()->PeekPacketTag(tag);

and also get this error:

* error: expected primary-expression before ?>? token         auto dataTag
= data-> getTag <ns3::ndn::Ns3PacketTag> ();*

could you give me some hint?

Regards,

Fatemeh

Hi Teng,

a solution is to add the information as an NDNLPv2 tag. You can take a look at the following commits, where I have done the same thing for the HopCount tag for the latest ndnSIM release:

https://github.com/named-data-ndnSIM/ndnSIM/commit/73df9f587e1c16c4f67a0053fe29b68f523ff138

Hi,

the lfu replacement policy has not been implemented in the case of NFD. You will have to implement this policy on your own. You can take a look at the responses to your previous email:

There is no such thing. The size of Interest is variable and depends on what name you use.

> Second, how can Increase and decrease the Interest packet size?

Use different name, e.g., put different amount or smaller/larger name components.

You can check the logic in AggregateStats policy.  If I remember correctly, it is the number of interests (not their size).

You can use those, but I cannot tell what you're expecting in your scenario.  Only you can tell what is expected from the scenario.

Yes, there is not "GetPacket" method in the ns3::ndn::cs::EntryImpl or it's base class.

For this one gcc is not too helpful with C++ syntactic sugar (clang actually gives a good suggestion), but it is easily fixable.  You need to add "template" keyword:

    auto dataTag = data-> template getTag <ns3::ndn::Ns3PacketTag> ();

Should work afterwards.

Hello:
     I have found a strange problem on use ndn::StackHelper::setCsSizs(), I want to use nfd::cs::Cs as my ContentStore?Here is my code ,
//begin 

//end

The code  is quite simple ,But  It leads to a error


   The strangest thing is  if I write the code in examples/ndn-simple,It has no problem,But if I write in any other  example cpp,It leads to the error. Thank you!

Hi,

please use the reply-all option, so that our email exchanges are visible to all the users in the mailing list.

My understanding is that this error has to do with the fact that you tried to use the cs tracer in combination with the CS of NFD. However, the cs tracer works only in the case of the ?old? CS of ndnSIM.

I will open a ticket on redmine and, hopefully, this feature will be added soon.

Thanks for letting us know,

sorry because my VMWare is installed on windows I couldn't use the
following commands:
vagrant init ubuntu/trusty64
vagrant up
vagrant ssh
but about the steps I followed in installing is as bellow:

1) sudo apt-get install build-essential libsqlite3-dev libcrypto++-dev
libboost-all-dev libssl-dev git python-setuptools
2) wget http://downloads.sourceforge.net/project/boost/boost/1.62.0/boost_1_62_0.tar.bz2
 tar jxf boost_1_62_0.tar.bz2
 cd boost_1_62_0
 ./bootstrap.sh
 sudo ./b2 --prefix=/usr/local install
3) sudo apt-get install python-dev python-pygraphviz python-kiwi
python-pygoocanvas python-gnome2 python-rsvg ipython
4) mkdir ndnSIMcd ndnSIM
git clone https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3
git clone https://github.com/named-data-ndnSIM/pybindgen.git pybindgen
git clone --recursive https://github.com/named-data-ndnSIM/ndnSIM.git
ns-3/src/ndnSIM
5) cd <ns-3-folder>
./waf configure --enable-examples
./waf

and while using command ./waf I got the following error:

If you're using Ubuntu 14.04, why would you install boost from source?

Just create a new VM from scratch and install boost libraries using apt-get as described in the instructions.

Also, vagrant can be easily installed on windows (https://www.vagrantup.com/downloads.html <https://www.vagrantup.com/downloads.html>) and can simplify creation of VMs.

Thanks 
         Is there any other tracers can  calculate the hit ratio of NFD'CS, as the hit ratio is a necessary indicators   in  my experiment.

Hi,


please use the reply-all option, so that our email exchanges are visible to all the users in the mailing list.


My understanding is that this error has to do with the fact that you tried to use the cs tracer in combination with the CS of NFD. However, the cs tracer works only in the case of the ?old? CS of ndnSIM.


I will open a ticket on redmine and, hopefully, this feature will be added soon.


Thanks for letting us know,

The code  is quite simple ,But  It leads to a error

   The strangest thing is  if I write the code in examples/ndn-simple,It has no problem,But if I write in any other  example cpp,It leads to the error. Thank you!

Message-ID: <CAD6hRmmiApkPoB94K+t2L5wbbH24LsZS3KD1WA2s6-jJHthrQw@mail.gmail.com>

I am trying to use adhoc mode with ndnSim but i came to discover that i
can't use it because ndnSim doesn't forward an interest to the same
interface he came from.  So, How can i extend it so I can forward for the
same interface in the interface is in adhoc mode.

Hello,

after a thousand of execution of a scenario which was working fine, I 
suddenly have the following error when trying to execute a scenario.
Any idea?
Thanks

Hi,

This error has to do with waf and not ndnSIM (assuming that you have not edited any wscripts). I would suggest you do the following:

1) Try to clean your current build by typing ./waf distclean and then configure and build again.
2) If 1 does not work, clone the ns3 and ndnSIM repos again and configure and build from scratch.

Hi,

I have not tried to do that with the latest version of NFD, but the solution might be something along the lines of:

1) you have to edit this method of the forwarder class:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.5.0-30-g934f505-ndnSIM/daemon/fw/forwarder.cpp#L207

2) probably use a NextHopFaceIdTag indicating that the next-hop face is the incoming face

3) Potentially, modify the PIT lookup process, add the incoming face to the faceTable and add a next-hop with the incoming face to the created PIT entry.

Hope that this helps,

Hi Iahmer

I answered a similar question on nfd-dev.
http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2016-December/002169.html

Be sure to search all mailing list posts within a year before posting a new
question.

Yours, Junxiao
