Subject: [ndnSIM] NackTypes
Message-ID: <CADm-vn0X-OKAugK_fv3U5=0qqy6UsPkWLqxHM9=WvAUFfDo4mQ@mail.gmail.com>

*Hello Alex and everyone,
Currently, ndnSIM defines following NackTypes:*

*
0: NORMAL_INTEREST
10: NACK_LOOP
11: NACK_CONGESTION
12: NACK_GIVEUP_PIT*

*
What does mean NACK_GIVEUP_PIT, how it is working in existing ndnSIM 1.0 code?*

*Another question, how t conf. Interest NACK in order to be enable.*

*Any help?
**Kind regards,*

Subject: [ndnSIM] Implementing a new cache policy
Message-ID: <CAM3J8PoGgLmN+8sHSV8opi6hhbp_Eg77AdhCiT+_mkEb4NbyNA@mail.gmail.com>

Hi all,

I need to implement a new cache policy called pseudo lru policy.I am
currently using ndnSIM 1.0, referring to the source code of LRU policy
(lru-policy.h), it seems to me that the "policy_container" in the code
serves as a cache storage is a list. But in pseudo lru policy the policy
container must be a tree where the left child are the most recently used
items and the right child is the least recently used item.
I'm new in using boost intrusive algorithms, I don't know if it is possible
to use rbtree or splaytree and how can I initialize policy_hook_type,
container_hook,policy_container and parent_trie.

Thank you for your response in advance.

Subject: [ndnSIM] Question about sending link state information only to
 neigbors
Message-ID: <CA+CQka7jVD8+3LnugVq9FwDqHDvXdvrZ=zhNs9PhDh8i9yD+Zw@mail.gmail.com>

Dear ndnSIM users

I have a question about broadcasting messages in NLSR.
As I have figured out broadcasting link state information means that a
router sends LSAs to
all of its neighbors and each neighbor receiving this LAS, sends it to all
of its own neighbors too.
if I have figured it correctly could you help me where is the
implementation of this part
in NLSR source code?

Thanks for your attention and help.

Mahsa,

Nlsr uses ChronoSync <http://named-data.net/publications/chronosync/>
mechanism for this purpose in its communication module
<https://redmine.named-data.net/projects/nlsr/wiki/Module_description#2-Communication-Module>.
To the best of my knowledge, you may find communication module, which
handles sync logic, in
/src/communication/
and nsync (a copy of Chronosync for nlsr) in
/nsync

Thanks for your answer Mr.Abdollahi Sabet
Therefore my interpretation of broadcasting is correct?
Does ChronoSync also support sending LSAs only to straight neighbors and
not flooding them
through the whole network?

ndnSIM friends,














*I'm getting this:jpbaugh at Janeway:~/ndnSIM/ns-3$ ./waf

When I check in the directory ndn-cxx, there is in fact no interest.hpp.
It is inside the src/ subdirectory.  However, even if I modify
ndn-common.hpp from inside the model directory, to include the /src
subdirectory, it still doesn't seem like it's finding this file.

This is making me a bit nervous as to whether I have a shoddy build or a
legitimate build of ndnSIM.

I'm just trying to restore everything to the point I had it before I
switched to this new computer.  And I'm really frustrated with some of the
apparent changes, and would appreciate any help you can offer.

Thanks,

John

Greetings again all,

I tried commenting out... practically everything, and it can't even find my

#include "ns3/ndnSIM/ndn-cxx/data.hpp", whether or not I put "/src/" before
data.hpp or not.

ALSO, it seems some of the actual ndnSIM files have major errors in them...

Is 2.3 a dud, or am I simply doing something wrong?

Thanks,

John

Hi John,

The headers are automatically copied into build/ns3/ndnSIM/ndn-cxx/ folder by the build system.  ndnSIM folder is included (should be included) as part of -I compiler flags (you can check with ./waf -v invocation).

What I noticed is that the file you're compiling is inside examples/ folder.  This folder doesn't automatically add ndnSIM as a dependency.  This most likely the reason of your problems, but wouldn't guarantee that it is...

Alex,

Thanks for the response.  I'm finally tapping out and giving in.  I'm going
to try to do it with the template technique you recommended before.

Please let me know if I did this correctly, as the instructions are a
little bit vague in the README:

1.)  Since I already had installed ndnSIM using the instructions in Getting
Started on the main ndnSIM.net page, I don't have to perform another git
clone on ns-3-dev-ndnSIM.git or any of those files right?  It seems it's
just downloading a separate copy of ndnSIM to put in a separate directory.

*So, all I did per the instructions was a git clone on the
ndnSIM-scenario-template-git.*
2.)  I placed the downloaded branch (terminology might be off here) in
my-simulations, *which in turn I have inside the ndnSIM folder*.  So,
my-simulations is a directory that is a sibling directory of ns-3 and
pybindgen, all three being inside the top level ndnSIM folder.

*Is this correct / ok?*
3.)  I am very confused about the difference between the extensions and
scenarios directories.  I was under the impression I could put a
subdirectory under extensions named as my scenario, so I named a
subdirectory of extensions "jpb-strategy1-test", which contains
jpb-strategy1.cpp and a umd/ directory with some classes I'm using (they
worked fine with ndnSIM 2.1.)

*Is this correct?*
4.)  Now, it cannot find the scenario, regardless of whether its inside
extensions or scenarios.  Does a .cpp or .cc file have to be at the top
level or can I put a subdirectory?  I just want to remain organized.  I get
the following:



*jpbaugh at Janeway:~/ndnSIM/ns-3$ ./waf --run=jpb-strategy1-testWaf: Entering
directory `/home/jpbaugh/ndnSIM/ns-3/build'program 'jpb-strategy1-test' not
found; available programs are: ['subdir', 'scratch/subdir/subdir',

Thanks,

You don't need to clone ns-3 or ndnSIM again, as long as you have
compatible version.

Yes, this is correct. scenario template must be outside of ns-3 folder.

You may place multiple files in extensions/ folder, which will be linked
with every scenario.
Every file in scenarios/ folder is an individual simulation which must have
a main() function. Every file is linked with every object from extensions/
to create an executable.

You must first `sudo ./waf install` from ns-3 which installs ns-3 including
ndnSIM system-wide (optimized build is recommended), and then `./waf
configure` and `./waf` inside the scenario template.

Yours, Junxiao

Junxiao,

By "./waf configure and ./waf inside the scenario template", I took that as
the ./waf inside my my-simulations directory, correct?

I performed the ./waf configure from inside there *after *doing a ./waf
install (from inside ns-3 directory), and I get the following:

jpbaugh at Janeway:~/ndnSIM/my-simulations$ ./waf configure
Setting top to                           :
/home/jpbaugh/ndnSIM/my-simulations
Setting out to                           :

Checking for 'libndn-cxx'                : not found
The configuration failed
(complete log in /home/jpbaugh/ndnSIM/my-simulations/build/config.log)


My obvious assumption is that it cannot find the ndn-cxx library.  But I am
following the instructions by the letter.  This is a fresh computer and a
fresh install, so what might be the issue here?  And what is the best /
appropriate corrective measure, as I assume ndnSIM is already installed.

Thanks,

John

Hi John

The scenario template, as of commit 2b5b6f55f04982273e62127082a19459ec68ff43
<https://github.com/named-data-ndnSIM/scenario-template/tree/2b5b6f55f04982273e62127082a19459ec68ff43>
,
is compatible with ndnSIM 2.1, and may or may not work with other versions.
However, I do not see why the scenario template is looking for ndn-cxx,
because there's no "ndn-cxx" token in its wscript.

Yours, Junxiao

Junxiao,

That is peculiar...  perhaps I should ask a different question:

*Should I be using ndnSIM 2.3*, even?  Or should I just go back to 2.1?

If so, how might I accomplish this to ensure I don't get the newest version?

Thanks,

John

2.3 should be ok.  Which exactly repository you cloned for scenario-template?  I just checked with the one listed on ndnSIM website (https://github.com/named-data-ndnSIM/scenario-template.git <https://github.com/named-data-ndnSIM/scenario-template.git>) and everything is working.

The correct template repository should not have this check:

     ...
     Checking for 'libndn-cxx'                : not found
     ...

The you should have directory structure something like this

some-folder-for-simulations/
??? ns-3/
?   ??? ...
?   ??? src/
?   ?   ??? ...
?   ?   ??? ndnSIM/
?   ?   ?   ??? ndn-cxx/
?   ?   ?   ??? NFD/
?   ?   ?   ??? model/
?   ?   ?   ??? ...
?   ?   ??? ...
?   ??? ...
??? pybindgen/
?   ??? ...
??? scenario/
    ??? README.md
    ??? extensions/
    ?   ??? README.md
    ?   ??? some-code.hpp
    ?   ??? some-code.cpp
    ??? graphs/
    ?   ??? ...
    ??? results/
    ??? run.py
    ??? scenarios/
    ?   ??? README.md
    ?   ??? scenario-name.cpp
    ??? waf
    ??? wscript

When you're inside scenario/ folder, you can run `./waf --run scenario-name` (files in scenarios/ folder are getting compiled into individual scenarios).

Alex,

This is where I found the instructions:

https://github.com/named-data-ndnSIM/scenario-template

The README file on that page says to do:


*git clone git://github.com/cawka/ndnSIM-scenario-template.git
<http://github.com/cawka/ndnSIM-scenario-template.git> my-simulations*

The wscript from this location does contain a reference to the libndn-cxx
library.

I think the README needs updated...  It uses a different repository.

I'm about to try the tests again.

Thanks,

John

Alex,

I'm getting closer.  With the link to the scenarios you provided me, I was
able to put my files in scenarios folder and try ./waf configure and ./waf
from ndnSIM/my-simulations.

I used a different, simpler scenario now, called jpb-4-print.  I now get
this error when I attempt to run it.  It compiles now, but appears to have
a linker issue:

jpbaugh at Janeway:~/ndnSIM/my-simulations$ ./waf
Waf: Entering directory `/home/jpbaugh/ndnSIM/my-simulations/build'
[1/2] Compiling scenarios/jpb-4-print.cpp
[2/2] Linking build/jpb-4-print
Waf: Leaving directory `/home/jpbaugh/ndnSIM/my-simulations/build'
'build' finished successfully (5.089s)




*jpbaugh at Janeway:~/ndnSIM/my-simulations$ ./waf --run=jpb-4-printWaf:

Ooops.  The instructions in README pointing to wrong places.  Will fix that.

As for the shared library error.  Assuming you're on Linux, restart or running `sudo ldconfig` should solve the problem.

Subject: [ndnSIM] How to update FIBs after producer's handoff
Message-ID: <8d17bd7e60123d7e4fda6c48577645f9@ce.sharif.edu>

Dear ndnSIM users,

I want to update routers' FIB after Producer's handoff. I have read
something about RIB management but I do not know how I can use that in
my code and I could not find any example. Can anyone help me?

Thanks already in advance for your help.

B,

In simulator you can use ndn::FibHelper
<http://ndnsim.net/2.3/doxygen/classns3_1_1ndn_1_1FibHelper.html>::AddRoute.
Those are static member functions, so you don't need to have a fibhelper
object to call them. In real environment you need to send commands
using Interests, which I recommend you to use the first one if you are not
working in real environment.

Regards,
Sabet

Hi,

I agree with Sabet that the easiest way should be to use the FibHelper to manually install and uninstall routes.

Thanks,

Alex,

The *ldconfig *command worked.  Restarting didn't.  Everything seems to be
running fairly smoothly now.

Thanks for your help!

Subject: [ndnSIM] Custom Strategy for Interest data collection - not working?
Message-ID: <CAOD1O2k7LkkDC_n-cAcyLq0Fc7NmYdoKCkWpLA0yg1-9LyaY9w@mail.gmail.com>

ndnSIM friends,

I am continuing a previous attempt at creating a Custom Strategy, for the
primary purpose of recording information on Interests as they arrive at a
router.

The three involved files, linked in my Google Drive are:

1. *The scenario file:*   (jpb-strategy1-test.cpp)
     https://drive.google.com/open?id=0By9ufeKqmJYYWXNpbEFYSEI2VWc

2. *The PopularityStrategy.hpp file* with my custom strategy specification
     https://drive.google.com/open?id=0By9ufeKqmJYYQm5BQVRSQzNjSnc

3.  *The PopularityStrategy.cpp file* with the implementation of the custom
strategy class
      https://drive.google.com/open?id=0By9ufeKqmJYYcTFXc1ZUcnpfQTA


Notes:
- I have the scenario file in the *scenarios* directory (I'm using the
template from GitHub)
- I have the PopularityStrategy.[hpp,cpp] files in the *extensions *
directory
- I subclassed MulticastStrategy to create the PopularityStrategy
- I did call NFD_REGISTER_STRATEGY at the top of the PopularityStrategy.cpp
file

Everything compiles just fine, but I get *no printout from the
PopularityStrategy *class.  I have cout<< inside both the constructor and
the afterReceiveInterest function.

It's as if it's not being used at all.

I am very much at a loss, and would greatly appreciate assistance on this.
It's close.  I can feel it.  :)

Thanks,

John

I think you forgot to configure FIBs, e.g., using GlobalRoutingHelper.

Hi Teng

You can't. Forwarding strategy only deals with Interest forwarding and Nack
returning. Data returning is controlled directly in incoming Data pipeline
and outgoing Data pipeline.

Yours, Junxiao

the above stated data packet handling is not forwarding strategy's job, but it sounds to me like one indeed can tweak outgoing data pipeline in ndnSIM to add the effect of some delay, right?

Teng, wonder why you'd like to add delay for data?  Just curious.

(I know similar thing for IP experimentation, for dealing with the impact of long delay links, eg satellite, or in a local imitated environment for long haul networks)

?Teng,
?


I've heard there have been some experiments for such modification at the
time of cache hit, in order to hide the fact that some content has been
retrieved from cache. So, if it is the matter,
? I guess?
you may work with Forwarder::onContentStoreHit
?. But that would affect every ndn node.?

Hi Sabet,

Thanks for the message. This is a good point to add delay before entering
outgoing Data pipeline.

Hi Lixia,

The delay is to avoid collision in wireless ad hoc networks. I didn't tweak
nfd forwarder, which is possible though. I added delay on ns3
NetDevice before sending ns3 packets.

Thanks,
Teng

Hi Lahmer,

Why don't you append sequence number to the name itself?

Alex and others,

I have updated the code:
https://drive.google.com/open?id=0By9ufeKqmJYYY3Rzem5EN0ZyREE

I even included the PolicyToFile class that does successfully print content
store related things to the file.

But even after adding GlobalRoutingHelper functions, I cannot get this to
work.  I'll assume it's not a problem related to me subclassing
MulticastStrategy rather than Strategy, is it?

But, I'm doing everything that is in the example on ndnSIM's website.  I
used the RandomLoadBalancer as my example.  It still isn't working.

I'm not even at the point where I'm doing much with the actual
interests...  I just want to print out information when an interest is
received, and when the object is created initially (i.e., when the ctor is
called.)

Any help would be greatly appreciated, as always.  If anyone could run the
code and see if you can figure out what's going on, I'd be very appeciative
(make a umd subdirectory for the Policy class .hpp and .cpp, or change
around the includes - doesn't matter, of course)

Thanks,

John

Alex,

I think I've got this right.  Let me know if you have any problems
downloading the necessary files:

Thanks,

John

Anyone get a chance to look at this?  I am truly at a loss.

Here is a quick patch to "fix" the issue.  It is a requirement to have STRATEGY_NAME **as a static variable** in the strategy class.  Otherwise, strategy is simply not being registered properly.

Also, while possible right now, the strategies are not designed to be overridden.  In the upcoming release, it would result in compilation error.

Hi,

most probably, you do not create the data packet in the right way or probably you do not encode/decode it correctly.

Alex,

When you say that the strategies aren't intended to be overridden, do you
mean those such as MulticastStrategy?

I assume Strategy will still be overridable.

My entire purpose for this code isn't to actually modify the strategy, but
to be able to use an existing strategy, with some logging / data collection
occurring.

I'm ultimately going to use the data collected about interests in the
Policy.  So the classes will have to interact.

Also, from your description, I now assume STRATEGY_NAME must have that
exact name, and is used elsewhere besides just setting the default
parameter?  Is this behavior / requirement documented anywhere?

Thanks,

John

Message-ID: <390cb4f.1384f.1597c4205d8.Coremail.dyao@mail.ustc.edu.cn>

Hi, I am working on an application where I want to tag each interest sent by the consumer with a node'score so that when Data return, the node on the path  will be able to know whether or not cache the data. so is there a way to put a socre(double) tag inside an interest and Data package?

Hi,

one solution would be to put the score into the name. Another way would be to use an NDNLP tag (take a look here for further details: http://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-December/003250.html). A third way would be to modify the Data and Interest classes of the ndn-cxx library to add the score as a field of the Interest and Data packets.

Sorry for the confusion.  Yes, I meant only strategy instances such as MulticastStrategy. Strategy is a base class and, of course, will be overridable.

You could just copy the code of the strategy and modify that.

I am not sure what you mean here.  The upcoming changes (already pushed to master branch of official NFD repo) include a few changes on how strategy name can be used, including passing additional parameters.  Though, not sure if this was your question.

Subject: [ndnSIM] Per-interface (face?) statistics?
Message-ID: <CAOD1O2m4gsbiwNP9DPACav9a0w366A38FA82DsdKygAdiS3ovQ@mail.gmail.com>

ndnSIM friends,

I'm mostly just mulling over some ideas about this for the time being, but
I'd like to get some information from anyone reading this, with some
insight.

Consider several Consumers connected to a router, which is then connected
to a Producer (or multiple producers - just consider one for now)

1.  Is it correct for me to assume that each connection between a Consumer
at the router is a Face (interface?) or is there any sharing?  E.g., do
consumers 1, 2, 3, 4, etc. ever connect to the Producer with the same face?

2.  I'm trying to see what would happen if an attacker hijacked a node or
nodes at focused their attack on an individual interface (face), so is this
equivalent to compromising one or more consumers?
    -->  In other words is there a one-to-one correspondence between the
Face and the Consumer always?  If not, when is this not the case and can it
be controlled?

Thanks,

John

I assume you meant consumers *physically* connected to a router (i.e. via a layer-2 connectivity)

it is up to what is that layer-2 connection is, whether each consumer is connected by a separate wire, or all consumers share the same media (e.g. Ethernet)

Prof. Zhang,

It is an honor to hear from you.  Thank you for your reply.

1.  What I mean by "connected" in the context of my simulation that I'm
preparing is that, for a simple case, I have used the *AppHelper *to
create *ConsumerCbr
*nodes (although others, such as ZipfMandelbrot could be used in the
future, I assume) --I install links using a *PointToPointHelper *in a
configuration like so:

      [consumer] <---> [router] <---> [producer]
      [consumer] <--------^

Is the default behavior such that an individual Face is created between
each consumer and the router?

2.   I ask the above, because I don't explicitly designate a face when
creating a link.

Thanks,

John

Yes, there is an individual face between each consumer and the router.

Hi John,

If you're using PointToPointHelper (or the AnnotatedTopologyReader) then you have a one-to-one correspondence between the link and the created Face.  However, you can use other links (and not yet implemented face implementations for ndnSIM) where one link may correspond to more than one face.  This, for example, could be with WiFi links.

John,

Following Alex, I suppose it could be said that there are different cases.
Face

> transport mechanisms.

You may have a multicast face which corresponds to multiple NICs with
multicast capability. Or you may even have a unicast face on top of a
broadcast channel(*lower level transport mechanism*) like wifi.

Hi,

you could take a look at the ScheduleWithContext method of NS3:

https://www.nsnam.org/doxygen/classns3_1_1_simulator.html#a5ba9b2de598375791433f1bb9ba9ca83

With this method, you can determine the time that you want NS3 to execute a specific event for you and you should be able to specify a method of the strategy choice helper as that event.

Hope that this helps,

You tried to declare your tag like I did here, but instead of uint64_t to use a double type and it did not work?

CALL FOR PAPERS
The fourth INFOCOM 2017 Workshop on Name-Oriented Mobility:
Architecture, Algorithms and Applications (INFOCOM 2017 NOM Workshop)

Atlanta, GA, U.S.A. on May 1, 2017

http://infocom2017.ieee-infocom.org/workshop/nom
=========================================================

The organizing committee is delighted to invite you to the fourth
INFOCOM 2017 Workshop on Name-Oriented Mobility: Architecture,
Algorithms and Applications (INFOCOM 2017 NOM Workshop) in Atlanta,
GA, U.S.A. on May 1, 2017.

Mobility support facing unprecedented challenges due to ever
increasing number of mobile devices at global scale, ever increasing
ranges of diversity of these devices, and ever increasing demand of
both data volumes and security requirements by these devices; these
challenges demand a new exploration of supporting
architecture. Information-Centric Networking (ICN) is a promising
direction to transition towards the data-oriented communication with
one of the research focus targeting specifically mobile and wireless
environments. In recent years, ICN is attracting a widespread interest
from academia and industry, with involvements from industry forums,
and consortiums. Instead of host-to-host communication model, as in
the current Internet architecture, named-oriented networking shifts
communication towards a data-centric model that focuses on retrieving
named and secured data, instead of host-to-host connections. ICN
secures named data directly, giving it an advantage over current
Internet solutions that only secure the communication channels between
hosts, a mismatch for wireless and mobile networks. Furthermore, ICN?s
data-centricity (i.e., independence of specific attachment points in
the underlying networks) makes it a promising direction for 5G
networks which aim to utilizes multiple radios nodes with connectivity
across multiple radio technologies

Name-oriented networking offers a new mobility network paradigm to
meet mobile device characters and mobile data routing, processing,
storage, and retrieval. Thanks to its native design based on data
naming (request for data forwarded based on data?s names and data is
returned using the reverse path of the request), name-oriented
networking enables user and devices mobility across multiple radio
technologies and is a good candidate for mobile/wireless networks,
including 5G networks. In addition, ICN technology is promising in
offering a scalable networking layer for IoT applications, including
massive sensor devices that suffer from the lack of mobility
management in the IP architecture and the lack an efficient storage,
security, and sharing means.

Hi dyao & Spyros

Declaring a *tag* with double type should work.
However, declaring an *LpHeader* with double type needs additional work.

LpPacket only knows how to decode
<https://github.com/named-data/ndn-cxx/blob/09bcab5bb80f655fd75271440c6cce03147fcb45/src/lp/detail/field-decl.hpp#L49-L57>
and
encode
<https://github.com/named-data/ndn-cxx/blob/09bcab5bb80f655fd75271440c6cce03147fcb45/src/lp/detail/field-decl.hpp#L84-L92>
uint64_t,
in addition to WireDecodable+WireEncodable and Buffer iterator range.
You'll need to specialize DecodeHelper and EncodeHelper for double type,
which involves defining the wire format for double type.

Yours, Junxiao

Hi Alex,

I am trying to limit interest scope to a set of say 3 hops, I found the GetScope and SetScope command, though it is mentioned that it limits the interest up to 3 host. Kindly let me know how can I limit my interest forwarding scope. An example would be greatly appreciated.

Hi all and good day.

I have confused, averagingPeriod parameter can be found in all metrics in
ndnSIM (such as CsTracer, L3AggregateTracer and L3RateTracer), which is
represented "How often data will be written into the trace file (default,
every half second)". However, the AppDelayTracer metric does not include
this parameter, even this parameter is highlighted on the website
http://ndnsim.net/1.0/doxygen/classns3_1_1ndn_1_1_app_delay_tracer.html
 My question here, how can enable it, I mean I want to obtain data about
for delays between issuing Interest and receiving corresponding Data packet
every half second in app-delays-trace.txt.

Thanks for help!

Regards

Raaid

 subclasses
Message-ID: <CAOD1O2nwizMuamsA34L4dDqYsfArquOtq1O8Z0aw7fWOo=C5wg@mail.gmail.com>

Greetings ndnSIM friends,

I need a way to communicate between the Strategy and Policy subclasses.  I
am creating a custom Strategy, and a custom Policy subclass.  I need
information about the interests coming in, which will affect decisions that
the Policy makes.  So, it stands to reason that I will need some sort of
communication between the two.

To do this, my idea is to obtain a reference/pointer to each, and then to
have a custom method in one (or both) of the classes to setStrategy or
setPolicy so that I can maintain an internal reference (using aggregation.)


So, for the Policy, I can call getPolicy on the Content Store.

But what about the Strategy object?  Is there a way to obtain this?

Either way it seems I'd need a reference to both.

Thanks,

John

Also:

I'm aware of the getStrategy() member function in the
StrategyChoiceHelper.  It returns a Name object, not a Strategy object.

Obviously, the strategy would be for a particular node.  I need it for my
router node.

If you have an alternative to this, I'd be very happy to entertain the
idea.  If there was a different "afterReceiveInterest" somewhere else, I
would be very pleased to use it, but I apparently need the one in the
Strategy.

Thanks,

John

Hi,

the easiest way would be to attach your custom consumer to each forwarder node (or to the forwarder nodes that you need) and let it send Interests towards the destination. In this way, the data packets would be cached by the local NFD.

Hope that this helps,

Subject: [ndnSIM] How to fail a node
Message-ID: <baf83dbc-81db-03db-e69a-2054c54f6c93@lacl.fr>

Dear ndnSim users,

Is there a way to simulate a node failure during simulation? Something 
like "kill the node" or deactivate the node.

Also using "ndn::LinkControlHelper::FailLink", I observe something strange.

In my scenario, I have something like this:

node1:consumer

node2:producer

node4:producer

node3: intermediate node


node1-----------node2

|                        |

|                        |

|                        |

node3---------node4

I use "ndn::LinkControlHelper::FailLink" to fail the link between node1 
and node2, the interests from node1 timeout, which means that node1 
tries to send the interests to node2 and not to node4 through node3.

Any idea about this behavior? Is it related to the strategy(best route 
is used)?

Thanks,

Junior

Hi,

my guess is that this is related to the forwarding strategy. Can you try to use the load balancing strategy?

I would say that you can simulate a node failure by stoping the application running on the node for some time and then start it again (or use the LinkControlHelper, like you did, if it is more convenient to control the link between 2 nodes).

Hi Spyridon,

Thank you for your help.

I am trying what you suggest but when enabling the load balancing 
strategy using  ndn::StrategyChoiceHelper::InstallAll("/prefix", 
"/localhost/nfd/strategy/random-load-balancer"), the result is the same.

Also, how can I stop an application at runtime to simulate the node 
failure? I am trying something like this: 
"Simulator::Schedule(Seconds(3),ns3::ndn::ConsumerCbr::StopApplication,nodes.Get(2));", 
it doesn't work.

Thank you for your help.

Junior

Hi,

in your simulation scenario, use something like the following (this refers to the Start method, there is also a Stop method that you can use):

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/examples/ndn-tree-cs-tracers.cpp#L95

Subject: [ndnSIM] Implement a new cache policy
Message-ID: <CAM3J8PpFR6MQfOC9p-MSECGDzr=aJFGR+WmMn3bZs5ca3=kEiA@mail.gmail.com>

Hi all,

I need to implement a new cache policy.I am
currently using ndnSIM 1.0, referring to the source code of LRU policy
(lru-policy.h), it seems to me that the "policy_container" in the code
serves as a cache storage is a list. But in my policy the policy
container must be a tree where the left child are the most recently
used items and the right child is the least recently used item. I'm
new in using boost intrusive algorithms, I don't know if it is
possible to use rbtree or splaytree and how can I initialize
policy_hook_type, container_hook,policy_container and parent_trie.

Thank you for your response in advance.

Hi lahmer,

Be advised that you can have mobility and mobility models, but for handover
events, since they are written for lte in ns3 and lte heavily relies on ip,
therefore you cannot use those.

Message-ID: <CALrx89NtxU-de+kekTzMymrQ-DW2xNmNnFnwFK8n-ZfeR=vQXw@mail.gmail.com>

Hello,
I am running a code of ndn-tree-cs-tracers.cpp. I am able to see the last
packets for a node in the "visualizer" (as in the screenshot below).
However, i wish to know if this can be implemented directly in the program.
 i want to see the "data" and "interest packets". Please provide an example
how it could be done.
Thanks..

Hi,

I cannot see the image you attached, plus I am not sure I understand the issue here.

With the visualizer, you can see the packets exchanged among the nodes. You could also use the packet tracers to output the packets received at each node to output files:

Hope that this helps,

I feel that this piece of documentation will be very useful for new users to ramp up with ndnSIM and understand how to use it properly. I would like to ask you to take a few minutes and review this page and let us know your comments/suggestions on how to extend and improve it.

Your time and feedback will be highly appreciated!

On behalf of the ndnSIM team,

Hi,

Sorry for the image problem. I am reattaching the screenshot. I wanted to
filter the packets which are going through the nodes and save as .txt file.
I have gone through the link which you have mentioned in your mail.
In addition to this I wanted to know is it possible to aggregate the size
of data passing through a particular node.

Regards,
Aniket

Subject: [ndnSIM]  Filtering of Traces
Message-ID: <CALKy0XZy-Lr6+n-kheKqxomSGc=FUepQmdkYKu4e0P=pb+YpcQ@mail.gmail.com>

Hello All,

I am working with NDNSIM to get traces of PIT, FIB & CS from nodes and I am
successful to get those traces. Now I want to use those traces and
aggregate / filter (like which node is having highest flow, what is the
total number of packet flow in my topology etc) them to get a compact form
of workable information. Along with that I want to get the information
about the processing time of the interest packets and actions taken after
processing in the nodes.

Please help me with examples.

Thanks
 MD

Hi MD

Usually I use grep, gawk, and similar command line utilities to process all
kinds of traces and logs.
Then, LibreOffice Calc or Microsoft Excel is used to analyze the numbers.

Hello
I want to install nlsrSIM alone instead of installing it together with
ndnSIM-NLSR,
but after the ./waf command,  in face-Controller.cpp file, the installation
process runs into some errors.
I appreciate if you help me figure out why this happens so I can install
this application.
Thanks.

Hi Mahsa

It appears that the installed ndn-cxx version is higher than what nlsrSIM
expects. Either downgrade ndn-cxx or upgrade nlsrSIM until they are
compatible with each other.

Dear Junxiao

Thanks for you quick response. When I try to install nlsrSIM together with
ndnSIM-NLSR no such error appears, I think the errors are because of trying
to install nlsrSIM alone.

Hi Junxiao.

Thank you for your response. I aggregated the results of our simulation.
Other then this I wanted to filter the packet flows according to the type
of data (like video, audio, voice) in my topology. Can you help me with
some ideas how can I push data's which have all video, audio and voice file
in the flow in NDNSIM and then filter them according to their types?

Thanks & regards

Hi Mahsa,

Sorry for late reply. Why you want to do that?

nlsrSIM is a different code branch, and basically the NLSR renamed for its
porting into ndnSIM.  ndnSIM-NLSR is the actual ndnSIM code base. I agree,
these names are bit confusing.

Both these are the renamed repositories during hackathon for NLSR porting
into ndnSIM. nlsrSIM can't exist without ndnSIM-NLSR so don't try it. If
you really want to install nlsrSIM alone, you can install NLSR itself.

/anil.

Dear Junxiao

Thanks for you quick response. When I try to install nlsrSIM together with
ndnSIM-NLSR no such error appears, I think the errors are because of trying
to install nlsrSIM alone.

Hi Anil

Thanks for your reply. Actually I want to replace nlsrSIM in ndnSIM-NLSR
with another application,
While compiling my application together with ndnSIM-NLSR, I ran into some
errors, so I thought maybe it would be a good idea to
first compile my application and then compile it together with ndnSIM-NLSR,
but as you said it is not possible.

Subject: [ndnSIM] Memory leaks
Message-ID: <CAB8_EN7mfELoG_jEcZv945oxQsxVoDNY5+S6OF-fJ+7y7iD6-Q@mail.gmail.com>

Hi,

I had an application on ndnSIM version 0.2.8, and it was working too fine.
Now I'm using the latest version, I changed the old application to work
over the new ndnSIM and noticed huge memory leaks that are proportional to
the run-time; On some computer it took more time and consumed 10 GB of RAM
!! and on another faster one, it took less, hence consumed less RAM (4 GB
or less), both are still huge amounts of memory as I'm using a small
topology with 18 nodes and an average frequency of 500 requests/s; and all
of that was running fine on the older version of ndnSIM.
Any ideas?

Regards,
Sa'd

Hi,

we have some clues that under some certain circumstances, there might be something wrong going on with the memory consumption.

However, it is not clear to us yet why this is happening. We speculate that this has to do with NFD itself and the way it maintains and deletes its data structures (specifically, PIT and CS).

I can get back to you with more details as soon as we are done with our investigation.

Thanks,

Can you clarify a bit (if you can share a simple scenario that highlights the issue, it would be even better). Was the memory consumption growing or got to a point of high utilization and stabilized (you said it is run-time, but then mentioned that simulation finished).  The reason I'm asking is that the old version of ndnSIM had optimization of "virtual payloads", which is not available in the new version.  This has impact on the amounts of memory used, but it should be just a constant factor increase, not continuous increase during runtime.

No stabilization, it keeps growing up till the end of the simulation (Yes,
it finishes). So if the same simulation ran on two different computers; the
faster one would finish before, hence consuming less memory than the
slower, the growing stops just when the simulation ends. (You have a rate
of growing equal to X MB/s, so taking long time to finish would lead to
consume more!)

Got it.  Can you share your scenario (a simplified version of your scenario), so we can try to debug?

I have no problem, but I've made some customized apps in "src/ndnSIM/apps"
(3 cpp and 3 headers) + 1 app in "scratch" + 1 txt file in the main
directory. That would be OK?

Hi,

I also recognized this memory leak. In some cases the memory consumption 
of my simulations increase linear over the time; at the end of the 
simulation they consume up to 60GB. This problem especially arises in 
scenarios where Multicast is used as FW-Strategy and many packets are sent.

I?m currently working with ndnSIM-2.1 (Commit-Hash: a9d889b).

Regards,
Philipp Moll
