Hi Jiebo

TagHost can only be used with subclass of ndn::Tag, not ns-3 tag.
ndn::Tag can only be used to pass information between components of the same software. Once a Data is encoded, the Tag isn't part of wire encoding, and thus will not reappear on the next node when the wire encoding is decoded again. Likewise, Tag will be lost when a packet goes between NFD and a local application, which also traverses a face.

ndnSIM 2.2 and below allows passing ns-3 packet tags between nodes. This feature is pending removal in the next ndnSIM release.
You should really encode information as part of wire encoding, such as in part of Name or Content, instead of relying on Tag.

Yours, Junxiao

Subject: How to Use Tag in ndnSIM 2.1

Hi junxiao,
  I'm a postgraduate in University of Science and Technology of China, and a beginer for ndnSIM. 
  I found that the class Data is inherited from tag-host, so I wrote a MyTag inhrited from ns3::ndn::Tag, and there's only an Integer in MyTag, and I added it to data, but once the data was send to next node, I got nullptr when the function getTag<ns3::ndn::MyTag>() was called.


-------------------------------------------------------------------------------
ns-3/src/ndnSIM/NFD/daemon/fw/forwarder.cpp   void Forwarder::onIncomingData(Face& inFace, const Data& data)


shared_ptr<ns3::ndn::MyTag> mytag_ptr = data.getTag<ns3::ndn::MyTag>();
    if(mytag_ptr == nullptr){
      std::cout<<"forwarder: onIncomingData: mytag_ptr = null"<<std::endl;
    }
    else{
      int tag = mytag_ptr->get();
      std::cout<<"forwarder: onIncomingData: mytag = "<<tag<<std::endl;
      if(tag > 0){
        mytag_ptr->decrement();  
        std::cout<<"forwarder: onIncomingData: after dec :mytag = "<<mytag_ptr->get()<<std::endl;


        if (m_csFromNdnSim == nullptr)
          m_cs.insert(*dataCopyWithoutPacket);
        else
          m_csFromNdnSim->Add(dataCopyWithoutPacket);
      }
      data.setTag(mytag_ptr);
    }
-------------------------------------------------------------------------------
I got "forwarder: onIncomingData: mytag_ptr = null" using ndn-simple. Part of the result below:
-------------------------------------------------------------------------------
producer:  mytag = 2
producer:  setTag 
node(2) responding with Data: /prefix/%FE%1D
onIncomingData face=258 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag = 2
forwarder: onIncomingData: after dec :mytag = 1
onOutgoingData: face: 256; data:/prefix/%FE%1D
onOutgoingData: tag: 1
onIncomingData face=257 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag_ptr = null
onOutgoingData: face: 256; data:/prefix/%FE%1D
onOutgoingData: tagptr=null: 
onIncomingData face=256 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag_ptr = null
onOutgoingData: face: 258; data:/prefix/%FE%1D
onOutgoingData: tagptr=null: 
App::OnData:/prefix/%FE%1D
------------------------------------------------------------------------------
Please kindly let me get your guidance how can I get this correctly.

Hi Jiebo

3.I got this code in Producer::OnInterest:

Look at "trivial producer", data->setContent line.


I'll leave other questions to someone else.

Hello Everone?

I want to get the contents of PIT,such as InRecords,OutRecords and the Interest.What I believe is I can get the contents from nfd::pit::Entry::getInRecords/getOutRecords/getInterest.But I meet some problems.If I have defined the "Ptr<Node> node" before,and then,run the code about:"Ptr<nfd::pit::Entry> entry = node->GetObject<nfd::pit::Entry> ();" It will give me the wrong answer like this: 

And so as to the "Ptr<nfd::Pit> pit = node->GetObject<nfd::Pit> ();" Can you tell me the reason(s)?If I cantn't do like this. What should I do to get the contents about the PIT? 

I am looking forward to your guidance and support.

Best Wishes,

Hi,

you could do something like:

Ptr<L3Protocol> protoNode = L3Protocol::getL3Protocol(nodes.Get(<node-id>));
Pit pit = protoNode->getForwarder()->getPit();

You might have to use the appropriate namespaces, but the logic to get the PIT instance of a node is the one I demonstrated above.

Hope that this helps,

Hi Runtong

Spyros has given the right way to do it. I'll address why the two snippets
are wrong.

Ptr<nfd::Pit> pit = node->GetObject<nfd::Pit> ();
>
In ns-3 object model
<https://www.nsnam.org/docs/release/3.25/manual/html/object-model.html>,
ObjectBase::GetObject can return an object aggregated into the current
object, or cast the current object as a subclass type. nfd::Pit is not
aggregated into the node, so this does not work.
If ndnSIM is designed ground-up following ns-3 principles, nfd::Pit should
be aggregated. But nfd::Pit is imported from NFD codebase that is not
designed for ns-3, so that it's not aggregated.

ns3::ndn::L3Protocol, as mentioned in Spyros's answer, is aggregated into
the node, and serves as an entrypoint to access NFD's objects.

Ptr<nfd::pit::Entry> entry = node->GetObject<nfd::pit::Entry> ();
>
ns-3 object model allows only one instance of each object to be aggregated.
Since each node has multiple Interest Table entries, it's wrong to
aggregate the entry.
Similarly, a ns3::NetDevice is not aggregated into a ns3::Node.

Hi John

To get the CS and enumerate its entries:

Ptr<L3Protocol> l3 = L3Protocol::getL3Protocol(node);
const Cs& cs = l3->getForwarder()->getCs();
for (const auto& entry : cs) {
  ..
}

Message-ID: <CADU-sK=WiZLasd6fFLrg_rCP1rk0QOFXUfUJtakvxb8nnEhamA@mail.gmail.com>

Dear NDN researchers,

As far as I investigate, all the names of FIB and PIT are stored in the
name tree data structure.
Is there anyway to measure it while running NDNSIM?
Since they are all stored in the same structure, can I know the separate
sizes of those FIB and PIT in KB?

In addition, if there are two different names, such as "AB/V",
"ABCD/DFDS/DFDG"
Do they take up a different amount of memory?

Best wishes,

Hi,

there is a ?size? method for each structure, however, this returns the number of entries for each one.

To get the size in KB, you have to do the math and figure out how many bytes are allocated for each entry of a structure. Every time that a new entry is created, you add the size of the entry to a variable representing the overall structure size in KB, every time an existing entry is deleted, you subtract from this variable.

And, yes, for the names that you mentioned, different amounts of memory have to be allocated. That has to do with the fact that they do not have the same number of name components. It might also have to do with the fact that each name component has a different number of characters (do not remember the very low-level details of the library. For each component, the library might allocate a fixed amount of memory no matter how many chars there are in the name component and does proper resizing in the case that the characters require more memory, but again I am not sure about that).

Hope that this helps,

troubleshoot and find out why I can't connect to ndnsim.net.

I can access all other sites I go to, just not ndnsim.net.  I've refreshed
the DNS cache on my Windows machine, reset the router, etc.  Nothing.

*This site claims it is not up:*

http://www.site24x7.com/public/t/results-1478283984902.html

Strangely, I seem to be able to access it on my phone when I'm using my
data plan.

I suspected this had to imply that my own network must by the problem, but
I have literally tried everything and this site above seems to imply the
same thing - that there's a problem.

I get ERR_NAME_RESOLUTION_FAILED in Chrome, but it also gets a similar
error on other browsers.  I have changed the DNS server to a manual server
(8.8.8.8 and 8.8.4.4) and pretty much tried everything else.  This is
maddening.

Any ideas?

Thanks,

John

Hi John,

There is a temporary problem with DNSSEC for ndnSIM domain.  This is why resolution can fail sometimes, when your resolver actually verifies validity of DNS records.  Should be fixed soon.

Hello,

Thanks very much for your quick and patient answer both of Spyridon and Junxiao.Based on your guidances,I can get the size of PIT already.But,What I really want is the Name,InRecords and OutRecords.And I find that they are in "nfd::pit::Entry" but not in "nfd::Pit".So,if I follow your advices and call the code of "pit.getName()".Then,The computer will give me the error :"const class nfd::Pit has no number named 'getName'".So,I'd like to know how can I get into "nfd::pit::Entry"and print the "Name" out? 

Looking forward to your response.

Yours,

Runtong

Message-ID: <CAOD1O2nF58UP5T2e1eJL+m6cXJa9=OzoR-fr-FOXSz_Sw95ZgA@mail.gmail.com>

Greetings all,

Is there a way to obtain the content store (old content store) and then
iterate through the entries?  Is there any way to add and remove items to
it or do you have to go through some other technique?

Also, am I correct in assuming the Cs type is the NFD content store, and
ContentStore is the old version?

Accessing the data in these stores, the PIT, etc. is very important for
many peoples' research, I suspect.  A tutorial or some more information on
this would be excellent.

Thanks,

John

Greetings again all,


   - Okay, so here is what I understand:  The Cs class is the *new *NFD
   content store class, correct?

   - In one of the e-mail exchanges, I was told that I could implement
   doAfterInsert( ) to control what was added into the content store (by
   allowing it in, then evicting it immediately if it didn't adhere to a
   custom set of requirements I could put in place.
   - There is no documentation in the NFD revision 3 for doAfterInsert, but
      I thought that the current version of ndnSIM uses this version of NFD?

      - Do I obtain an instance of the Cs, or is all the work done with
   static methods?  (e.g., ::find, ::insert, etc.)

   - In the ns3::ndn::cs namespace, there is a ContentStoreImpl - is THIS
   the actual implementation of the old content store?  Or the new?  Do we
   ever use this one directly?


Thanks again, everyone.  Still trying to make sense of the some of the
various classes and their relationships.

Thanks,

Message-ID: <CAAtwdrEGtiKnGjYdzPhX=u1p2yZfcB4kxQ1ZCbETtTb8NUGiMA@mail.gmail.com>

Hi, people.

I need to get how many times cs updates are performed at a node and I need
that this information be available to adjacent nodes through faces. I know
that i have to add a counter in CS policies but I do not know how to make
nodes advertise this information, from time to time, to adjacent nodes. It
would work like face counters, but I have checked that these counters are
updated when interests and data flow through nodes. I want that node's cs
information updates should be sent, for example, at every 10 s , so that a
custom strategy would used as a metric to forward interests.

I appreciate any help.

Hi Igor,

As far as I see, the easiest way is to write a custom application which
sends your wanted parameters in interest name in a multicast fashion.
But if you want to publish this information, as a part of a dataset built
into NFD, personally I think it is a bit more complicated from
implementation perspective.

Sabet

Hi,

the PIT class does not have a getName method. An entry of PIT has a getName method. You can use the iterators to access the entries of PIT (or/and std::find if you want). When you actually get a PIT entry, you can apply the getName method to it (or the methods to get the InRecords and OutRecords).

Hope that this helps,

Subject: [ndnSIM] My Test file for manipulating/playing with the content
 store
Message-ID: <CAOD1O2nt6Up=RFOvZSLfwsdo83JVLd3s3RP_=rVJuExX0t6XGQ@mail.gmail.com>

Greetings all,

I have written some code that I'm basically trying to use to just play
around with the content store for the purpose of learning how to use it.  I
figured I could create (or retrieve) an instance of it, and treat it mostly
like a container/data structure and use the methods, such as insert on it.
I tried making my own custom Cs instance, and when that didn't work I used
the technique Junxiao suggested by obtaining the L3Protocol, and then from
that obtaining a forwarder and then getting the content store that way.

I assumed that once a content store was obtained, that I could do things
like call "insert" on it directly.

However, although what i have attached does compile, I get a termination
error saying that the error was "bad weak_ptr".

I've spent several years not as focused on C++, so I will be the first to
admit I'm not as up to speed on the smart/managed pointers as i should be,
but i do know that weak_ptr is a type of associated smart pointer that
doesn't own the object that it is referencing.  But even after using GDB, I
still don't really know what's causing this problem.  Java and C# have
spoiled me... I'll admit.

Any help would be greatly appreciated.  I am beginning to put together
notes and maybe some day in the near future I'll have a little sandbox
tutorial for people to at least get use to the data structures and such
with a more extensive treatment.  I'm a community college instructor,
adjunct at U of M, as well as doing this PhD research, so once I truly
understand this stuff better, I think I can really contribute especially in
the form of instructional materials.

Thanks a ton, everyone.

John

Message-ID: <CAEv4q0aKfZf8G5hp-Q5YH_R0fu7iMTVg=dTm7tQszbVm1E20bw@mail.gmail.com>

Dear NDN researchers,

I have added an additional attribute(metadata) to an Interest and a data
packet.
Currently, I use it like this below

https://github.com/NDNUtils/NDNSIM/blob/master/src/ndnSIM/apps/ndn-consumer.cpp#L188-L191

Name myName;
myName.append("AB");
shared_ptr<Name> uidName = make_shared<Name>(myName);
uidName->appendSequenceNumber(seq);

However, this way seems to be so primitive.
I believe that there must be a way to set my additional attribute in the
script file.

Can any of you tell me how to use this additional attribute in a script
file?
I hope this is simple to do it.

Best wishes,

inchan hwang

Message-ID: <CAEv4q0YMuvH=cE3TaTN4jnBkw7iLTTA+xaSCzVxDuOYPFhfr1g@mail.gmail.com>

Dear NDN researchers,

I have been trying to access a node and get its information in a script
file.
In my script,
Ptr<Node> node0 = nodes.Get(0); .// to access node,

std::cout << "Missed Int for node 0  : " <<
node0->GetObject<ns3::ndn::L3Protocol>()->getForwarder()->getNameTree()->size()
<< std::endl;
// To get information.

Strangely, it only works until
 "node0->GetObject<ns3::ndn::L3Protocol>()->getForwarder()" but not further
than it.
I cannot access getPit or whatsoever.

I was using this approach because of the code in the visualizer.

https://github.com/NDNUtils/NDNSIM/blob/master/src/visualizer/visualizer/core.py#L401-L414

Can anyone of you tell me how to assess the information? such as getPit(),
getNameTree() and so on?

Best wishes,

Dear ndnSIM team members:


         I have stuck on a puzzle on the ndnSIM 1.0 of version when complementing my experiment.
         The experiment is about to verify the security of ndn network by flooding the interest to the network. 
         But when we use the flooding forward strategy and Nocache in Content Store in the ndn-tree-cs-tracers.cc with our topology, the interest didn't forward to all faces of the node, it forwarded to only one face.
         First, we modify the flooding.cc to let the interests sent to all faces, but the interest kept sending to each face repeatedly without a stop. 
         Second, we add a default routes in ndn-stack-helper.cc with our prefixes, but the interest is only sent out by one face.

         Could you help us to complement this flooding method without repeatedly sending same interests?
         
         Thank all of you very much! 


Sincerely.

Thanks for your answer very much.With the help of "const nfd::Pit::const_iterator iterator = pit.begin();",I can print the Name out.And the code is "std::cout << (*iterator).getName()<<"\n";".But I meet two questions now.The first one is why I can't use "std::cout << (*iterator).getInRecords()<<"\n";" to print InRecords out?And the error is"cannot bind 'std::ostream {aka std::basic_ostream<char>}' Lvalue to 'std::basic_ostream<char>&&'".If I can't do like this.What should I do?The second one is that I find there has no member of 'next' in 'nfd::Pit'.So if I want to iterator the pit::entry,what should I do to let the iterator goes to the next?

I am thankful for your guidance and support.
sincerely,
Runtong

Hi, Everyone

I need to find out the node id which the requested content retrieved from its cache. How and in what part of pipeline forwarding I can send this node id along with content to the customer using ns3PacketTag? (I need this information just for the simulation and results evaluation.)

Hi

I want that some nodes inform each other (immediately after caching the content) that each one has cached what content and store its name in nodes. If I use set data structure to store the name of content in each node, is it preferred to implement this set in an application or in NFD?
I appreciate any help.

Message-ID: <CAOD1O2kko5RTYWkFkjKZPGaxOo6EjtH4of98OJ51t0D6hgTxGQ@mail.gmail.com>

Any ideas?  I sent the full code in a previous e-mail.  But here is the
offending section:





*     ndn::Data tempD;     string testStr = "Testjpb";
tempD.setName(ns3::ndn::Name(testStr));     //put in Cs?
myContentStore.insert(tempD); *

Shouldn't I just be able to do this?  Assuming I retrieved a Content Store?

Thanks,

John,

Try this:

auto tempD = make_shared <ndn::Data> ();
.
.
.
myContentStore.insert(tempD);

I'm on sell phone right now and just wrote from the memory. But I think
this will do.

Hi John

Many places in NFD and ndn-cxx assume the packet (Interest or Data or Nack)
are created with make_shared, even if the API takes a reference instead of
shared_ptr.
When a packet is created directly without make_shared, undefined behavior
occurs which is usually bad_weak_ptr.

Yours, Junxiao

Hi,

I have a ns-3 application located in "utils". I could easily include it in
the consumer application as well as producer application; no errors. Now, I
need to include it in the forwarder, but I got many strange errors ! How
should I compile the forwarder with my ns-3 application ?

You are all awesome!  Thanks a ton.  It worked.

It would be great if some documentation existed that explained that aspect
of the packets.

Thanks!

Hi,

1) an inRecord is a class that has some certain methods and attributes. Please take a look here to see how you can get the attributes that you want:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.3.4-ndnSIM/daemon/table/pit-in-record.hpp <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.3.4-ndnSIM/daemon/table/pit-in-record.hpp>
https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.3.4-ndnSIM/daemon/table/pit-in-record.cpp <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.3.4-ndnSIM/daemon/table/pit-in-record.cpp>

2) You have to iterate through the entries of the PIT. A PIT has multiple entries and you need to move the iterator forward to point to the next entry.

Hi Junxiao,


Many thanks for the reply.


I learned that I can attach ns3 packet tags to deliver message just after I sent the first email, but I didn't understand why ndn tag could not do the same thing, so thanks again for the explanation for ndn tag, now I understand that. But I still got something to figure out:


1.Since the feature is pending removal in the next ndnSIM release, how can I encode information in packet or data, can you give me some usual/common methods to do so.


2.You mentioned encoding information in part of Name or Content, Consumer requests content by name, if I changed its name, will it be correctly consumed ?


3.I got this code in Producer::OnInterest: 
  data->setContent(make_shared< ::ndn::Buffer>(m_virtualPayloadSize)); 
 It seems the producer makes a virtual content and adds it to data's payload, how can I add information to content? 


Can you give me some advice to deal with the above?


Thanks~


Jiebo Chen

Hi Jiebo

TagHost can only be used with subclass of ndn::Tag, not ns-3 tag.
ndn::Tag can only be used to pass information between components of the same software. Once a Data is encoded, the Tag isn't part of wire encoding, and thus will not reappear on the next node when the wire encoding is decoded again. Likewise, Tag will be lost when a packet goes between NFD and a local application, which also traverses a face.

ndnSIM 2.2 and below allows passing ns-3 packet tags between nodes. This feature is pending removal in the next ndnSIM release.
You should really encode information as part of wire encoding, such as in part of Name or Content, instead of relying on Tag.

Yours, Junxiao

Subject: How to Use Tag in ndnSIM 2.1


Hi junxiao,
  I'm a postgraduate in University of Science and Technology of China, and a beginer for ndnSIM. 
  I found that the class Data is inherited from tag-host, so I wrote a MyTag inhrited from ns3::ndn::Tag, and there's only an Integer in MyTag, and I added it to data, but once the data was send to next node, I got nullptr when the function getTag<ns3::ndn::MyTag>() was called.


-------------------------------------------------------------------------------
ns-3/src/ndnSIM/NFD/daemon/fw/forwarder.cpp   void Forwarder::onIncomingData(Face& inFace, const Data& data)


shared_ptr<ns3::ndn::MyTag> mytag_ptr = data.getTag<ns3::ndn::MyTag>();
    if(mytag_ptr == nullptr){
      std::cout<<"forwarder: onIncomingData: mytag_ptr = null"<<std::endl;
    }
    else{
      int tag = mytag_ptr->get();
      std::cout<<"forwarder: onIncomingData: mytag = "<<tag<<std::endl;
      if(tag > 0){
        mytag_ptr->decrement();  
        std::cout<<"forwarder: onIncomingData: after dec :mytag = "<<mytag_ptr->get()<<std::endl;


        if (m_csFromNdnSim == nullptr)
          m_cs.insert(*dataCopyWithoutPacket);
        else
          m_csFromNdnSim->Add(dataCopyWithoutPacket);
      }
      data.setTag(mytag_ptr);
    }
-------------------------------------------------------------------------------
I got "forwarder: onIncomingData: mytag_ptr = null" using ndn-simple. Part of the result below:
-------------------------------------------------------------------------------
producer:  mytag = 2
producer:  setTag 
node(2) responding with Data: /prefix/%FE%1D
onIncomingData face=258 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag = 2
forwarder: onIncomingData: after dec :mytag = 1
onOutgoingData: face: 256; data:/prefix/%FE%1D
onOutgoingData: tag: 1
onIncomingData face=257 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag_ptr = null
onOutgoingData: face: 256; data:/prefix/%FE%1D
onOutgoingData: tagptr=null: 
onIncomingData face=256 data=/prefix/%FE%1D
forwarder: onIncomingData: mytag_ptr = null
onOutgoingData: face: 258; data:/prefix/%FE%1D
onOutgoingData: tagptr=null: 
App::OnData:/prefix/%FE%1D
------------------------------------------------------------------------------
Please kindly let me get your guidance how can I get this correctly.




With Best Regards.

Hi,

It seems that  "model/ndn-app-face.hpp" has been changed for "model/ndn-app-link-service.hpp"

https://github.com/named-data-ndnSIM/ndnSIM/commit/c018a561d0f74f64cdfca01cccde0718f7dfb968#diff-b950357034ce4fca244e4f8d08ad9d9b


Yours,

Junior

Hi Charif

You may use
face.getScope() == ndn::nfd::FACE_SCOPE_LOCAL

https://github.com/named-data-ndnSIM/NFD/blob/2df8f8176eaa306f5d8fa48c9903cb692c2dd031/daemon/face/face.hpp#L141

Subject: [ndnSIM] IsLocal()  method was removed from Face ?
Hi,

I have an issue with my simulation after updating to the last NDN-sim code. It seems that the method isLocal() cannot be used on the Face no more.
Any thoughts that might help are welcome.

Thanks per advance for your help.
Charif

Hi pei ren,

This happens because PyViz visualizer  is not enabled.

You can verify that by looking in the " Summary of optional NS-3 
features:" given by "./waf configure"

Hi WangZijian,

Check http://ndnsim.net/2.1/cs.html <http://ndnsim.net/2.1/cs.html> and http://named-data.net/techreport/ndn-0028-1-ndnsim-v2.pdf <http://named-data.net/techreport/ndn-0028-1-ndnsim-v2.pdf> TR for a bit more explanation.   Unless you specifically request an old version, nfd::cs will be used.

I'm assuming you're using macports on macOS.  If so, you need to completely remove them and reinstall from scratch, as it needs to be done for every major macOS upgrade (see more here: https://trac.macports.org/wiki/Migration <https://trac.macports.org/wiki/Migration>).

Message-ID: <CADU-sK=5FVxPkfiNRq-WBAgK5Dh2VCwgAMOeEbOxHmFxJ7sENg@mail.gmail.com>

Dear NDN researchers,


I made a script that runs a scenario of a consumer and five producers.

When I run it, only three of them exchange Interests and data with the
consumer. The other two producers
do nothing.
If I make another consumer that consumes the data from the other two, then
the communication works.

Is there any constraints on a consumer that it allows a certain number of
producers at a time?


Best wishes,

inchan hwang

Hi,

When I include a header file in forwarder.hpp, I receive the following  
strange error. My header file is a ns-3 application. I look forward to  
your comments.

Thanks,

Hi Sarah,

ndnSIM is based on NS-3, so it's better to understand some basics of NS-3
first. Here is the conceptual overview of NS-3 (
https://www.nsnam.org/docs/release/3.25/tutorial/html/conceptual-overview.html#key-abstractions)
and reading code examples also helps.

In NS-3, you can simulate different scenarios with the topology, link-layer
protocol, network-layer protocol and applications that you want. For
example, you can choose a grid topology, install point-to-point or wifi at
link-layer, and install TCP/IP stack at network-layer.

ndnSIM provides NDN stack as a new network-layer protocol for NS-3. To
simulate NDN over WSN, you can install link-layer with other NS-3 modules,
e.g., LR-WPAN, or WiFi (ad hoc), install NDN stack at network-layer and you
may also want to configure nodes with limited resources, depending on your
scenario.

Best,
Teng

Hi,

there are no constraints on that. This behavior most probably has to do with the prefix that the producers announce, the name of the Interests sent by the consumer and/or the FIB entries that have been installed at each forwarder.

Hope that this helps,

Hi,

most probably, there is a circular dependency somewhere that has to do with the header files that you have included.

Hi Junior?


his problem happens, you can using command "Thank you very much for your answer and patient, the Question is really what you said loose visualizer module, using "./waf configure" i can see the word visualizer is under the "Modules not built", the major aim of this email is to tell others who face the same problem during the install process that when this problem happens, you can using command "sudo apt-get install python-setuptools", than the word visualizer will disappear from "./waf configure", hope this can help those people face the question as me.
Another more, thank you Junior, thank you for you email.

Hi pei ren,
     
This happens because PyViz visualizer  is not enabled.
     
You can verify that by looking in the " Summary of optional NS-3       features:" given by "./waf configure"

Greetings all,

So I don't break my current ndnSIM 2.1 - is there an easy / suggested way
to upgrade to 2.2?  I just don't want to brick ndnSIM trying to upgrade it.

Thanks,

John

Runtong,

I'm new to ndnSIM also, and Spyridon or one of the other more experienced
members can correct me if I'm wrong, but in a sample I was working on, this
is how I got information from the *content store*, and I suspect it's
*similar* to the *PIT*:

Given a Content Store initialized thusly:
* //get the content store for the node     *
*     nfd::Cs& myContentStore = l3->getForwarder()->getCs();*

I iterate through the items:

* //use iterators to move through the content store*
*     for(auto it = myContentStore.begin();*
*         it != myContentStore.end();*
*         ++it)*
*     { *
*        cout<<it->getName()<<endl; //it represents a shared_ptr*
*                           //to a single Data item*
*     } *


Hope this is useful to you and others.

John

Hi John,

If you haven't add your custom modifications, then the following commands should do the job

    cd ns-3
    git pull origin/ndnSIM-v2
    cd src/ndnSIM
    git pull origin/master
    git submodule update --init

If you made modification, then in addition to the above commands you may need to fix your updates. Check the changelog for the list of API changes.

Subject: [ndnSIM] Setting a custom policy for Content Store
Message-ID: <CAOD1O2mDyKcNjmC4Vtm9u3JOcGmN0sGWO7tkSboAECJ0UcdPpw@mail.gmail.com>

I am trying code like so:

unique_ptr<nfd::cs::Policy> policy(new JPBPolicy());

myContentStore.setPolicy(policy);

I'm getting tons of errors.  It doesn't like any of the conversions I'm
trying to perform...  It may be a misunderstanding of some of the
techniques used with managed/smart pointers in terms of polymorphic
references, but something's not working.

I want to create a subclass of Policy in order to override functions such
as doAfterInsert(iterator i);

In my derived class (subclass), I did provide a body for all the pure
virtual methods from the documentation of Policy.

But I think the problem is the conversion.  Is there some way to do this
with say, static_cast ?

Thanks,

John

Hi John,

Can you post the exact error you're getting (if it is too long, you can use pastebin.com <http://pastebin.com/>).  If you also can share the snippet that reproduces the problem, it would be much faster to debug the issue and suggest the solution.

Hi John,

You have a small issue in your implementation of JPBPolicy.  If you haven't, you need to define the default constructor and in the default constructor use ``Policy::Policy(const std::string&)`` to initialize the base class.  You can see the example in other policies:

    LruPolicy::LruPolicy()
       : Policy(POLICY_NAME)
     {
     }

The reason is that each policy has to have a name, which is enforced by the deleted default constructor of the base class.

Alex,

Actually, as soon as I sent the last e-mail, I noticed that Policy didn't
have a default/no-arg ctor defined, so I went in and modified it to use
one.  I gave JPBPolicy a no-arg constructor, but used a passthrough to the
base class (Policy) constructor with the constant string.  I *think* I have
that part correct.

However, I still am getting the "use of deleted function" error related to
unique_ptr.


*Updated Errors:*
https://drive.google.com/open?id=1Ni2wc7mSecJR-1KseA_1k4oDKoXuJJrGNtwXl6sHnrA

*Updated jpb-policy-test.cpp:*
https://drive.google.com/open?id=0By9ufeKqmJYYOThERVMtOVo2STA

*Updated JPBPolicy.hpp:*
https://drive.google.com/open?id=0By9ufeKqmJYYV183emczZ01kM28


I neglected to include my Policy class last time.  And yes, I suppose using
separate compilation (.hpp and .cpp file for the JPBPolicy class) would be
better, but I'm trying to take it one step at a time! :)

I think some of this might be some misunderstandings with some of the new
C++ 11 and 14 features / smart pointer stuff.

Also, *do I need the *= delete for the copy constructor and = operator?  I
was reading in a few areas where that helped with the error I'm receiving,
but I don't know if those are necessary.

Thank you all so much,

John

Try replacing

myContentStore.setPolicy(policy);

with 

myContentStore.setPolicy(std::move(policy));

Not really.  These are already prohibited by the base class.  You can delete them in your class as well, but nothing really changes.

Message-ID: <CADU-sKng2aWbQMUMSkjwUZZUdd2sr8_KTosKiAma36xt7wutrA@mail.gmail.com>

Dear NDN researchers,

I am now making a scenario script based on ndn-simple-wifi.cpp file because
my scenario is about
simulating NDN wireless nodes.
When I run it with visualizer, it runs but there is no trace of any data
packet in CS.

When I use the code below,
auto csSize =
(*node)->GetObject<ndn::L3Protocol>()->getForwarder()->getCs().size();

csSize is always zero.

I am curious why there is not any example of NDN wireless explained in NDN
SIM website.
Does NDNSiM support wireless environment?

Best wishes,

inchan Hwang

Dear ndnSIM mailing list members,

Hello, I am Yoshimichi from Keio University, Japan.

Are there any substitutes of the class "Limits", which existed in ndnSIM 
1.0, in ndnSIM 2.1?
I've searched through the API Documentation, but it seems that the class 
"Limits" is missing from ndnSIM 2.1.

Any suggestions would be more than welcome, and thank you in advance.

Best regards,
Yoshimichi NAKATSUKA

Hi,

you are trying to access the size of NFD?s CS. If you are using the ?old? CS of ndnSIM, then it makes sense that the size of NFD?s CS will be 0, since it is not being used.

Hope that this helps,

Hi Yoshimichi,

ndnSIM 2.0 and later versions use NFD to do the actual packet forwarding. NFD does not do any rate limiting for now.

You could implement your own rate limiting mechanisms as a part of your forwarding strategy. Please take a look at the provided forwarding strategies and the NFD developer?s guide for more information:

Subject: [ndnSIM] Question on Visualizer
Message-ID: <CADU-sK=nSfZVKnx3FmOomU4t_kfegVTBqNHG3=jzkweZ88ES_w@mail.gmail.com>

Dear NDN researcher,

I am trying to show an attribute in the python visualizer that I have added
on my own.

in ndnsim_pit.py

 for item in ndnPit:
            tree_iter = self.table_model.append()
            self.table_model.set(tree_iter,
                                 self.COLUMN_PREFIX, str(item.getName()),
                                 self.COLUMN_FACE, str(item.getInterest()))

item.getName() works but my own attribute item.getProducerUid does not work.
Is there any file or setting I have to change to access to it?

Best wishes,

inchan hwang

Hi Hwang,

To get access to information from within the visualizer module, you need to implement the corresponding python bindings for your getter. If you have a simple data type, it should be straightforward.  Take a look into bindings/modulegen__gcc_ILP32.py and modulegen__gcc_LP64.py  (both files should have the same content)

 (nfd::cs::Cs)
Message-ID: <CAOD1O2nBkX4vv4z_Nq0q0gop9fi9S7pok-VrguR_saOuiK55DQ@mail.gmail.com>

Greetings all,

1.)  When I tried to use the erase( ) function to remove an item, I found
out that the method is not implemented.  I checked the code from the
documentation and found out that this is indeed the case.

So how am I supposed to evict a specific item from the Content Store?

2.)  I've noticed when I use ./waf --run=some-test that the system often
re-compiles tons of completely (as far as I know) unrelated files (the grid
samples, tracers, etc.).  This adds significantly to the time it takes to
run the test.  Any ideas why this might be happening?  I'm not using any of
the sample files, tracers, etc. - nor have I modified them for my current
tests.

Thanks,

John

Hello all:

Okay, please correct me if I'm wrong:

If I understand this correctly, when you create a custom Policy
subclass/derived class, *the developer *is responsible for creating the
three queues specified in the NFD Developer guide?  (unsolicited, stale,
and fifo)?  So we directly control what stays in the "queues" (std::list)
according the the policy that we can determine.  So the *Policy *maintains
the actual Entries, while the Cs maintains the Table of names?  I noticed
the three queues don't actually live in the cs.cpp or cs.hpp files.

I'm *still * a little confused about the Cs::erase method:  why isn't it
implemented?  How do we "trigger" a removal of an item from the Content
Store (Policy?)

Thanks,

John

Hi, John.
About your last queation, I believe that this has not been implemented
because Cs  removals are performed by the replacement  policies (Lru/Fifo),
which makes it unnecessary the implementation of a specific piece of
content. If you go through  both implementations, they have the method that
is in charge this.

void

LruPolicy::doAfterInsert(iterator i)

{

  this->insertToQueue(i, true);

  this->evictEntries();

}

Hope that helps.

Regards,
Igor.

So, if insert is called on the Cs, the only thing inserted is the data Name
into the table.  The actual entry isn't inserted anywhere because handling
the actual entries is up to.the policy?

Technically, we need to implement 'doAfterInsert' to do the actual entry
insertion into our own data structures?

Thanks

Hi, John.
About your last queation, I believe that this has not been implemented
because Cs  removals are performed by the replacement  policies (Lru/Fifo),
which makes it unnecessary the implementation of a specific piece of
content. If you go through  both implementations, they have the method that
is in charge this.

void

LruPolicy::doAfterInsert(iterator i)

{

  this->insertToQueue(i, true);

  this->evictEntries();

}

Hope that helps.

Igor.

Hi Aniket,

If you see that "ndnSIM" is enabled and 'configure' finished successfully, there is no reason to panic :)  Everything got configured correctly and the script just reporting what has been found and what has not.

The error is not related to ndn-simple.cpp, but to RemoteSystemTempFiles "scenario" that you have in your NS-3's scratch folder.  The scratch folder assumptions about how it handles .cpp files directly placed in the scratch folder (those assumed to be complete scenarios and must include main() function) and files places in a subdirectory in the scratch folder (those will be compiled into a single scenario and one of the files must have main() function).  From the error, I see that you haven't defined main() function in any of the scenario files in /home/a/KL/ndnsim/ns-3/build/scratch/RemoteSystemsTempFiles/RemoteSystemsTempFiles/ folder

Subject: [ndnSIM] Identifying an interface (face?)
Message-ID: <CAOD1O2moDjRpd6JeGx8neiOujSm_sksGxhgWE4b2cdDUSTu92w@mail.gmail.com>

Greetings again ndnSIM friends,

What is the appropriate way to identify what interface a particular Data
packet is received (or sent?) on?

Here's a scenario:

Assume there is a router, R with a Content Store, between a producer, P,
and several consumers, C1, C2, C3, ..., C*n*.

Will the router naturally have a single interface exposed for each
consumer?  Or can multiple consumers communicate over the same interface
(e.g., send Interests across the same interface/Face)?

I'd like to be able to determine how much and which data arrives on a
particular interface.  I suppose I somehow need to obtain a FaceId, and
somehow determine which Data arrives on that face?  Also, I need to be able
to distinguish between Faces among applications and NFD, and between NFD
and the "outside world" - i.e., which are ACTUALLY network interfaces.

Ideas?

Thanks,

John

P.S. - I am slowly, but surely, understanding this simulator much better,
and I appreciate all of your patience.  I am currently working on a very
thorough tutorial/reference for myself, and once somewhat refined with very
good examples I will release it to the community to help people get up to
speed even fast - at least that's the goal.

This depends on your topology.  If you're using PointToPoint links (this is the case in in most of the examples), then you will have a dedicated link between producer and consumers and, consequently, a dedicated face.

If you're simulating a multi-access link (e.g., WiFi scenarios), then it is not the case.

The answer depends on where you want to achieve this function.  If you're looking at the logs, the Face associated with the NetDevice identifies itself as netdev://[<mac-addr>]" (netdev prefix).  If you have a pointer/reference to the face and want to determine whether it is one to the outside world, you can use dynamic_cast:

Face* face = ...;
if (dynamic_cast<NetDeviceLinkService*>(face->getLinkService()) != nullptr) {
  // do stuff
}

Hi John

I would say looking at the face scope attribute is a more reliable solution
than testing for the exact type:

switch (face->getScope()) {
  case ndn::nfd::FACE_SCOPE_LOCAL:
    // application
    break;
  case ndn::nfd::FACE_SCOPE_NON_LOCAL:
    // network
    break;
  default:
    NS_ASSERT(false);
    break;
}


Yours, Junxiao

Hi Fateme,

If I've guessed correctly, you are going to store a subset of CS
information(the name of cached contents), in another data
structure(apparently some std::set) on nodes. Well, for previous cached
contents you should read their names from CS. For future ones, you may
catch them (of course with their names) at the time of being cached in
Forwarder. It seems to me nfd is where you'd better implement it, unless
you don't want all of your nodes have such information stored. Could you
elaborate more? How are nodes going to inform others of this information?
Is it something like exchanging FIB info in a routing protocol?

Thanks,
Sabet

*http://ndnsim.net/2.1/doxygen/classns3_1_1ndn_1_1App.html#a20fd3ef630b6d05dc139911d1ef1b17f
<http://ndnsim.net/2.1/doxygen/classns3_1_1ndn_1_1App.html#a20fd3ef630b6d05dc139911d1ef1b17f>*

When the documentation says:

"Method that is called at the time specified by Start"


Does this refer to ns3::ApplicationContainer's Start method (and likewise
Stop for the ns3::ApplicationContainer's Stop method)?

I come to that conclusion based on the example in:
http://ndnsim.net/2.1/guide-to-simulate-real-apps.html

Where we have:

*ndn::AppHelper appHelper("RealAppStarter");
  appHelper.Install(node)
    .Start(Seconds(6.5));*


So, I assume since Install on AppHelper returns an
ns3::ApplicationContainer, that this is the start and stop referred to?

Thanks,

John

Hi John,

Yes, you're exactly correct.  Start/Stop is referring the the ApplicationContainer.  This part is a bit confusing in NS-3 and our documentation didn't help either :-D  If you can make update (it is in docs/sources/guide.....rst file) and push it in some form, it would so great.

Message-ID: <CAP7VUROQMvsAfSW4QXZ-HXKUOGp300cEuC1nyaOOZ-Bto2pYUQ@mail.gmail.com>

Hi all,

I would like to print out the prefix name in PIT on to screen by using the
toUri() function in Name class. The topology is simple as below:


 *      +----------+     10Mbps      +--------+     10Mbps    +----------+
 *      | consumer | <------------> | router | <------------> | producer |
 *      +----------+         10ms      +--------+          10ms
+----------+
 *


Part of my program is like below:

  Ptr<ndn::Pit> pit = nodes.Get(1)->GetObject<ndn::Pit> ();
  Ptr<ndn::pit::Entry> entry = pit->Find(ns3::ndn::Name("/prefix"));
  ns3::ndn::Name name = entry-> GetPrefix();
  name.toUri();

When executing compile command ./waf --run 1 --vis I got below output:

Command ['/home/11/ndnSIM/ns-3/build/scratch/1',
'--SimulatorImplementationType=ns3::VisualSimulatorImpl'] terminated with
signal SIGSEGV. Run it under a debugger to get more information (./waf
--run <program> --command-template="gdb --args %s <args>").

Any one have clue on why this happens or how should I use the toUri()
function?

Thanks in advance.

Regards,

Lu Zhang

You can check to run the scenario in the debugger using the suggested command, but I would suspect that you're simply getting a segfault because there is no "/prefix" entry in the PIT (Find returns NULL and then you're dereferencing NULL).

Try checking if name is nullptr:

ns3::ndn::Name name = entry-> GetPrefix();

if(name != nullptr)
  name.toUri();
else
  cout<<"ooops!"<<endl;

Hi Guys,

Thanks for your prompt answer. Yes, the Ptr<ndn::pit::Entry> entry =
pit->Find(ns3::ndn::Name("/prefix")); part returns a NULL since Find uses a
exact match, there is no exact "/prefix" in my PIT.

Regards,

Lu Zhang

Actually "/prefix" is a prefix itself. Maybe it's better to getPrefix()
first, then try to Find.

Junior, ren pei,

And be advised that Visualizer works only if you compile all of ns-3
modules. If you are going to build ns-3 with a subset of modules e.g.
core,ndnSIM and some others, visualizer won't work because it has
some dependencies to all modules.

Hi Muhammad,

Thanks for your comment. I think we have to specify the PIT entry before we
can do a getPrefix().

Hi Muhammad,
A subset of CS information should be saved in another data structure. This information is not only related to the node itself but name of cached contents in some nodes (some nodes,not all of them) must be saved in this structure. These nodes send an interest in order to inform each other about their content's name with specific prefix. The receiver nodes of this interests have to divide the content's name and save it to their data structure.
regards,

Hi Fateme,

If I've guessed correctly, you are going to store a subset of CS information(the name of cached contents), in another data structure(apparently some std::set) on nodes. Well, for previous cached contents you should read their names from CS. For future ones, you may catch them (of course with their names) at the time of being cached in Forwarder. It seems to me nfd is where you'd better implement it, unless you don't want all of your nodes have such information stored. Could you elaborate more? How are nodes going to inform others of this information? Is it something like exchanging FIB info in a routing protocol?

Thanks,
Sabet

It seems the Policy is what actually holds the data, while the Cs stores a
Table of Names.

Hi Alex,

I am computing number of interest packet send by each node per second.

Ptr<const Interest> interest
interest->GetWire()->GetSize()

When I am printing the size of packet, I am getting same values for all
node. I did n't understand the reason. From my point of view, it should be
different.

Please suggest.

Thanks.

HI Pratyush,

It should be different if the name is different.  Make sure that your names are different in size.

Hi everyone,

I have a problem on ndn content store. I send a interest packet with a new
field. The field has its own verified token.
if there is the content in ndn cs, the cs will check the verified token.
Consumer can get the content in the cs when he pass the check by router.

I follow the lookup method of content-store-impl.hpp. But How can I add a
new mechanism in this method to authenticate the token?
May someone suggest me?   thx...

I'm not clear on exactly what you're asking, but perhaps you could
implement your own Policy (as a subclass/derived class of nfd::cs::Policy)
-> https://ndnsim.net/2.1/doxygen/classnfd_1_1cs_1_1Policy.html

You could use one of the protected members (override them in your subclass)
to do the additional verification / authentication:

Dear NDN researchers,

I have been thinking about packet deliverance issue.
In NDN sim, does all data packet come to the consumer according to the
number of issued Interests from it?

Over in NDN WIFI simulation,
Is there any possibility of the occurence of further delay between nodes if
there is not enough memory for PIT?
If it happens, How can I measure the time delay between nodes?

Best wishes,

ndnSIM friends,

When I create a custom example in the /examples directory and try running
it using ./waf --run=jpb-3-node, for example, it starts compiling no less
than a dozen completely unrelated files.  This slows down my
simulation/testing time significantly.  I would assume it should only
compile my new test file (a .cpp file) and any related files - not just
compile a ton of the tests seemingly randomly - not to mention the linking
process as well....

Should I not be putting new simulation tests in the /examples folder?
Should I just put them in /scratch?  Or is there something else I'm doing
incorrectly?

Thanks,

John

Check my tutorial slide deck https://named-data.net/wp-content/uploads/2016/10/6-ndnSIM.pdf <https://named-data.net/wp-content/uploads/2016/10/6-ndnSIM.pdf> around slide 16 and 17 :)

As long as you're adding your scenario code inside core NS-3, the compilation process will be slow.  It can be sped up in a few ways, but in general it will be slow.

Subject: [ndnSIM] Registering custom Consumers,
 Producers (or apps in general)?
Message-ID: <CAOD1O2mkSRoV3SvYnQZT84QZguBqgbR2dwGSU06DuaUqDR2d-g@mail.gmail.com>

ndnSIM friends,

In one of the examples, there is a line:

ndn::AppHelper consumerHelper("ns3::ndn::ConsumerCbr");

Where does it know to find ConsumerCbr?  Do I just have to put the
namespace and scope resolution operators if I, for example, create a *custom
consumer*, producer, or other app?

Also, there appears to be an *error in the documentation*,

http://ndnsim.net/2.2/doxygen/classns3_1_1ndn_1_1AppHelper.html#a67d941c1628aceef4b8add5c564ed3df

The parameter named in the constructor (the const string reference) is
named *prefix* in the header, but the description names it *app*.

Thanks,

John

Hi John,

The magic comes from NS-3's object system (in addition to standard object system that C++ provides).  For the class to be found by the name, e.g., in the AppHelper constructor, it needs to be so called "registered".

It is just a matter of adding `NS_OBJECT_ENSURE_REGISTERED(YourClass);` and implementing YourClass::GetTypeId() method that defines name, constructor, and any parameters that you wish.

Check apps/ndn-consumer-cbr.cpp for example.  You'll find similar code in many other "ns3::Object"-derived classes.

Message-ID: <CAOD1O2k_1bP6M-T8+yOUJhO+vVEX0U8UgCehnN-N992nv949Mg@mail.gmail.com>

ndnSIM friends,

Another question:  The examples imply, by use of the AppHelper's SetPrefix
method that a consumer, for example, can only issue Interest packets with a
single prefix.  Is this correct?  Can this value be changed in real time?

I would assume also that Producers could provide content from more than one
prefix.  To me, the prefix seems to correspond to a limited collection of
items.

Thanks,

John

Hi,

I would suggest that you take a look at this callback, which is overridden by each forwarding strategy and is called right before a pending Interest expires:

https://github.com/named-data-ndnSIM/NFD/blob/b6e7362f4343709aa945e2c4bb3e6f443f52aa9a/daemon/fw/strategy.hpp#L110-L111

It can, but you may have easier time to changing prefixes by writing a specialized producer applications.  The existing producer app is really very basic one without much logic in it.

John,

As far as I can review in my head, there should not be real problem. You
may have other ndn::Name variables for other prefixes in one application,
and fill them with appHelper::setAttribute. Then you may make thing more
complex in onData and onInterest.
But, what's the use of it? I mean, you want an application be responsible
for distinct prefixes and produce distinct content for each one? Or publish
the same content under different prefixes?

hello all:
    There are some question about ndnSIM source code recently i met, thank you very much if you have the answer of my confusedness!

on the site "http://ndnsim.net/1.0/fw.html", i can see many fw strategy here, while on my own source code folder, i even can not find "ndnSIM/model/fw/flooding.h" as show in site, there is only a folder named "cs" and other ".cpp" files. Even in /NFD/fw, i also can not file names "flooding.h", than i use "ctrl+f", i got nothing, system told me there is no file names "flooding.h",what should i do? how can i get access of these forwarding strategy?

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.

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?
if any one can help me, thank you very much!

best wishes.

Subject: [ndnSIM] How to manually set name of Interest and Data
Message-ID: <CADf8L0axGgeLNiBxvaoE2UyM5vHotnaDVcNzzfJQGfoRo=qGOg@mail.gmail.com>

Dear NDN Research Team,
Hello.
I want to send an Interest for a Data packet that does not exist. For
example, if a Producer has two Data packets /prefix/0 and /prefix/1, I want
to send an Interest for /prefix/2. In order to achieve this, I would need
to be able to set the full name of the Interest and Data packets.
When I was working with the the examples on ndnSIM 2.0, I could only find a
way to set the prefix.  In ndn-simple.cpp using the Helper
"consumerHelper.SetPrefix("/prefix")," it would automatically add 0, 1, ...
to the end of /prefix/. Then using the
"producerHelper.SetPrefix("/prefix")" the Producer would return the
matching Data packet, assuming it exist.
I do not want it to be assumed that it exists. Therefore, I would like to
know if there is a way to manually set all the names.
Any help would be greatly appreciated.
Thank you.

Best Regards,
Kengo Kaneda
