Hello,

Thank you for your help. Also, there is one more thing that I observed in my case.I have multiple consumers and producers in my scenario and for first interest packet there is a source which never sends a data back and there is another source which forwards first interest packet on other interface.

Can you please suggest me any reason for these observations?

Thanks & Regards,
Sharvari

Hi Sharvari,

There is no simple answer to your question.  Download times, besides multi/single path forwarding depends on client request pattern and congestion control (hop-by-hop and end-to-end).

ConsumerCbr may not be a great consumer to measure what you want, as it is sends interest at constant rate.  If it can retrieve set of data packets over single path, it will take the same amount of time (minus reduced interest reexpressing) to fetch of multipath.   You can try ConsumerWindow, but it has a very rudimentary logic that is trying to adjust client strategy to the available network capacity.

May be you should try to use different measurement parameter, which shows the effect of mutlipath strategy, without adding dependency on client requests.

Subject: [ndnSIM] Behaviour regarding two wifi nodes.
Message-ID: <CAKkT40mwtkPfWBZZJFa+ErHi3vKbvtBAGhuK0fW-HOZzb_8isA@mail.gmail.com>

Hello NS-3 Users,

I am studying wireless networks in ICN scenarios.
I made several simulations but as they didn't produced expected results i
restarted studying more in-depth the behaviour of my wifi nodes.

I run in particular 4 simulations in which there is 1 root, 2 AP and 2
wifinodes; basically the 2 wifinodes continue to request /prefix1 content
to the 2 AP that forward the requests to the root if they don't have the
SeqNo on their own. Each wifinode is connected to *only one AP* and the two
AP are connected to the root.

The range of the wifi-connections is X m. implemented with
("ns3::RangePropagationLossModel","MaxRange",DoubleValue(X)).

In many of these simulations I changed the position of the 2 wifinodes ( in
a symmetric way ) in order to keep them at the same distance Y > X but each
one always connected *to one AP*. The simulations gave me the same result
(same content requested in the same moment during the 3 simulations for
both of the nodes).

In the last simulation I put the 2 wifinodes at a distance Z < X but
keeping them always connected *to one and only one AP*.
In this case the wifinodes didn't request the same content in the same
moment but changed the order of the SeqNo requested and as result this last
simulation gave me a completely different result.

Honestly speaking I don't know why these 2 wifnodes if are in range have to
change their behaviour in terms of SeqNo requested, I can accept that they
interfere with each other in terms of delay in forwarding their request but
not that they change their SeqNo order to be requested.
Maybe I am completely wrong or I just don't see a parameter to change in
order to have what I want, in this case just forgive me!

The seed of the simulations was the same for all the simulations.

I posted this question also in the ns3 mailing list, hopefully i will
receive an answer!

Lorenzo

Hi Sharvari,

Are you publishing data under same prefix?  If so, if the there are other producer "closer" to the consumer, the producer may not get any interests.

Another possibility is that you may have missing routes.  Did you manually configured routes or used global routing helper?

Message-ID: <32F4999E-6E16-4208-AA98-80A14A6F0758@cs.ucla.edu>

Dear all,

since September 2015 and the latest version of ndnSIM (version 2.1: <http://ndnsim.net/2.1/#>) , we support the simulation of real applications (meaning applications written against the ndn-cxx library). This is a feature that enables the NDN application developers to write applications that can be deployed on the NDN testbed and at the same time port these applications to ndnSIM and evaluate their performance and design trade-offs in large-scale experiments (there are a few requirements for these applications ? please see <http://ndnsim.net/2.1/guide-to-simulate-real-apps.html>). As a proof of concept, we have ported a couple of real applications to ndnSIM:

1) ChronoSync: ChronoSync is a synchronization library for distributed realtime applications in NDN. In order to run ChronoSync in ndnSIM, you need to have the latest version of ndnSIM installed and also download the following ChronoSync scenario template: https://github.com/spirosmastorakis/scenario-ChronoSync

The readme file of this scenario includes instruction on how to build ChronoSync in the simulator. This scenario is based on a slightly modified version of ChronoSync that fulfills the requirements mentioned above: <https://github.com/spirosmastorakis/ChronoSync>

2) ndn-ping: This is an application from the ndn-tools repository. It implements ping consumers and producers. It can be found here: <https://github.com/named-data-ndnSIM/scenario-ndn-ping>

We encourage the research community to try this feature and port real application to ndnSIM. 

In general, if you have implemented a scenario-template that works with the latest version of ndnSIM, please let us know. We could fork your scenario to the original ndnSIM repository, so that your work is used by other members of the research community.

Thank you very much for your time!

Hi,

The issue I believe pertains to the point #6 and #7 in this article.
http://ndnsim.net/2.1/guide-to-simulate-real-apps.html

Can you please elaborate how this code should be modified it to work? The
related code which uses the io_service is here:
https://github.com/named-data/NLSR/blob/master/nsync/sync-socket.cc#L74

Note that the reference to io_service is taken from the ndn::face object as
recommended in point #6.

   -

   ndn::Face::getIoService()
   <http://ndnsim.net/2.1/doxygen/classndn_1_1Face.html#a517205cc925595c1a194fed7a98ebfb5>
   should be used only to obtain a reference to
boost::asio::io_service. *Application
   MUST NOT use any methods of* boost::asio::io_service, *otherwise the
   simulation will crash.*

   ndn::Face face;...// Supported (the rewired Scheduler

scheduler(face.getIoService());
   // Not supported in ndnSIM and will result in

You can get the pointer to the node sending the Interest as below. Get the
node Id from the node object.

 ns3::Ptr<ns3::Node> thisNode =
ns3::NodeList::GetNode(ns3::Simulator::GetContext());

To answer your other question, I think it depends how you write your
producer application logic. I think you should be able to filter out
certain Interest, based on where you want to remain silent or not.

Dear Anil and others,
I might not have made my question clear, actually I want to know when  an
intermediate node receives an interest, the id of the node who has
generated the interest.Not the node which is currently receiving or
forwarding that interest.

Hi,

you could just attach it as the last component of the Interest name and send it out. In this way, intermediate nodes can extract the last component of the Interest name and figure out the id of the node that generated this Interest.

Hope that this helps!

Thanks Spyros and Anil, definitely it will work.
Can you please specify how the last or any component of an interest name
can be read?

Hi,

to get the last component of a name, you can use the get method of the name class:

Name myName(?/this/is/a/test?);
std::cout << ?Last component: ? << myName.get(-1) << std::endl;

The above code should work.

Hope that this helps!

Message-ID: <CAFxAFZXvugY=B3j5f6KOLbPBw1j0pGzFeDoxhj8+hObUT+cH=Q@mail.gmail.com>

Hi,

I had added some attributes to data.hpp. Then I tried to change their value
in onOutgoingData. But received following error:

../src/ndnSIM/NFD/daemon/fw/forwarder.cpp:526:54: error: passing ?const
ndn::Data? as ?this? argument of ?void
ndn::Data::setCarlComponents(ns3::Ptr<CarlComp>)? discards qualifiers
[-fpermissive]
               data.setCarlComponents (cPointer);

Changing my attributes to mutable also did not help, i.e. only the same
error appeared later.

Thanks for guidance in advance.

Data in NDN is immutable.  You cannot modify en route, i.e., all security properties associated with the data will be gone.

If you need to add something alongside to help with forwarding, you should use tags instead.

Hi Chavoosh,

your question is kind of open ended. I would suggest you read the following webpage, where we discuss the requirements for a real application to be ported to ndnSIM:

http://ndnsim.net/2.1/guide-to-simulate-real-apps.html

Then, you could take a look at the existing examples of ported real applications to understand the overall approach:

https://github.com/spirosmastorakis/scenario-ChronoSync
https://github.com/spirosmastorakis/ndns-scenario
https://github.com/named-data-ndnSIM/scenario-ndn-ping

If you have more specific technical questions, I would be glad to help.

Hope that this helps!

Dear Chavoosh,

Anil Jangam has been working on porting NLSR to ndnSIM, which seem to be almost finished.
By I will let Anil to give more details himself.

Hi Chavoosh

I don't know about porting, but I doubt whether your goal can be achieved
with ndnSIM, depending on what you mean by "performance".

If "performance" means CPU and memory usage, ns-3 and ndnSIM cannot help
you.
You need ONL or Emulab for that.

ns-3 and ndnSIM can help you measure how many messages are transmitted, and
how fast does the routing system converge in response to an announcement or
fault.
Such results will be repeatable if simulation is implemented correctly.

Yours, Junxiao

Chavoosh,

As Alex mentioned, Anil Jangam is about to finish his porting of NLSR to ndnSIM.  Another option, if your topology is less than 100 nodes, is to use Mini-NDN which doesn't require porting NLSR.

Dear Spyridon,

Thanks a lot for your comprehensive answer. I see your point. You mean I
should assume NLSR as a real application and try to port it to ndnSIM,
which seems reasonable. Anyway, it would be much more helpful if I could
find a source code which has been already done this. Do you happen to know
there is such source code available?

 =================================================================

Dear Alex,

     It is a good news to me and I am impatiently looking forward to
hearing from *Anil* about porting NLSR to ndnSIM. Actually, I need to know
when he can release such version of NLSR.

=================================================================

Dear Junxiao,

     You hit the nail on the head! Actually, by ?performance? I mean
convergence time, message overhead, update dissemination time, and quality
of multipath routing support of NLSR, which can be resolved through
simulating it. As a matter of fact, I want to evaluate NLSR?s performance
with more than 200 nodes, and I cannot access to this number of PCs, so I
decided to use ndnSIM. But if you have a better opinion I will be so glad
to hear it.

=================================================================

Dear Lan,

I hope he can finish it ASAP and release the first version of ported NLSR
to ndnSIM. As I mentioned, I need to evaluate NLSR?s performance with about
200 nodes, but your suggestion seems to be really helpful (i.e. using
Mini-NDN) as Mini-NDN does not require porting NLSR, although it is limited
to 100 nodes. Thanks for your helpful suggestion.

=================================================================

 Again, I do appreciate your kind help and exact explanation and I am
looking forward to hearing from all of you.



Best regards

*Chavoosh*

 hello Carlz,in ndnsim version you can access content store data ( for example in ndn-forwarding-strategy.cc function)?as bellows. maybe it will be the same for version 2 ? Ptr<ContentStore> m_contentStore;Ptr<cs::Entry> csEntry=m_contentStore->Begin()?while ( csEntry !=m_contentStore->End()){
std::cout<<"the name of data in cache";
csEntry=m_contentStore->Next(csEntry);
}
Hope it will work for youregards

Hi Atish,

I am not sure why you are trying to install ndnSIM using a link from travis CI?

I would suggest you follow the instructions on our official website:

Hi All,
I am working on mobility models in NDN, i want to know did somebody
simulated the Kite model provided in research paper-
http://named-data.net/wp-content/uploads/2014/06/sigproc-sp.pdf

If yes then please let me know i just want to discuss how he simulated the
same results again.

Thank-you

Hi Monika

I'm unaware of such work.
You may watch NFD Task 3408 <http://redmine.named-data.net/issues/3408> to
get notified when someone starts working on bringing Kite to NFD.

Yours, Junxiao

I believe Yu Zhang <yuzhang at hit.edu.cn>, who did the KITE design, did do simulations.

Message-ID: <CA+Wzd2B_PcibWqmrrwKGhGig_SLB81CNDWcqO64HOjaPjFnVfA@mail.gmail.com>

Hi All,

I was wondering if the following forwarding strategies are implemented:

1- Round robin on multiple interfaces.
2- Weighted round robin.
3- Load distribution (Not Random) but based on criteria (Bandwidth, Loss,
Delay).

Thanks!

Hi Ahmed,

the forwarding strategies that are available in ndnSIM are mentioned here:

http://ndnsim.net/2.1/fw.html

Moreover, Steve DiBenedetto has implemented some load balancing strategies (including a random and a weighted load balancer). These strategies can be found here:

https://github.com/dibenede/ndn-tutorial-gec21/tree/master/strategy-templates

Hope that this helps!

Message-ID: <e2ee7bb6e8a8371f476979ed041c917f@ufpa.br>

 

Hello, 

Does anyone knows if ndn-simple-with-content-freshness.cpp scenario is working
fine in ndnSIM 2.1? Because when I run this scenario, the expected behavior
described in the scenario is not happening (i.e. Interests from 1, 3 and 4
will reach producers and Interset from 2 will be served from cache). 

Thanks in advance, 

Ivanes Ara?jo

Hi Anil,

I see your point and I know that you're busy as a bee! Actually, I'm
working on a paper and I have a hard deadline which does not let me wait to
release your code. Anyway, I want to make you sure that your code can be a
good basis for our future works and papers, so it can be really helpful to
have your code due next months. Finally, I really appreciate your help and
kind email and I'm looking forward to seeing your first release of ported
NLSR, ASAP!

Good luck with your thesis!

I have been reading some papers on Caching Techniques in ICN.I have been
reading q - caching in ICN (http://arxiv.org/abs/1512.08469) i was trying
to use Icarus for simulation their techniques but icarus dose not have a

Yes. You can find the simulation on:

I believe Yu Zhang <yuzhang at hit.edu.cn>, who did the KITE design, did do
simulations.

You may watch NFD Task 3408 <http://redmine.named-data.net/issues/3408> to
get notified when someone starts working on bringing Kite to NFD.

Hi guys,

a few clarifications first:

The current version of ndnSIM (version 2.1) supports both the use of NFD?s CS and the use of an ndnSIM-specific CS implementation. For the ndnSIM-specific CS, there are a number of cache replacement strategies already implemented and integrated with ndnSIM:

https://github.com/named-data-ndnSIM/ndnSIM/tree/master/model/cs

As far as the CS of NFD is concerned, as Junxiao mentioned, there is this project (originally, it was a project from the first NDN hackathon last September):

https://github.com/ndncomm/nfd-caching-policies/commits/master

Moreover, there are many papers that have explored in-network caching and cache replacement strategies using ndnSIM. Some of them provide implementation code as well or links to their code on github. It would be very useful for you to look up such papers online.

Hope that this helps.

Message-ID: <CAFxAFZVbHC2UX6itcJ5d94RVqHsO7QCupZ5eKcvuA28uRQ=8ew@mail.gmail.com>

Hi,

In ndn-producer.cpp, the data object is created in the "onInterest" method.
This means it is created upon receiving an interest. However, it seems that
in reality nodes have a kind of repository, e.g. a hard disk, in which they
maintain the data. To my understanding, data should be copied from the
repository to the cache upon arrival of a new interest message. How this
has been taken into account in ndnSIM ?. Looks like we do not have access
to the repository.

thanks.

Message-ID: <41E7DF15B39B5C46BF24C9545D39304C2ACADF67@oit-ex2010-mb1>

Dear ndnSIM list members,

I am working in a wireless scenario with N consumers and M producers, connected via intermediate nodes (see example below)

Consumer 1
O
   \
      O  --  O --  O  --  O ... O  --  O
  / Rtr-1                           Rtr-n   Producer 1
O
Consumer 2

Consumer 1 and 2 issue Interest requests via ConsumerCbr application (same namespace, e.g. /prefix/ ). As the number of routers increase, the link has more collisions and the Interest/Data packets get lost, generating more retransmissions and cache hits.

Is there a way to know which node originated the cache hit? Also, is there a way to know if a cache hit was originated by a retransmission or by a first-time Interest request?

I looked at "Finding Id of interest sending node<http://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-March/002455.html>" but that solution seems to not fit in this scenario.

Thanks for your help,

Thiago

Hi Thiago,

one quick and dirty way to do that is to append the node id to the name of the data packet as soon as you retrieve it from a cache (following the approach of the link that you mentioned). Could you be more specific why you think this would not work here? It will work, but you have to do this trick in the forwarder class of NFD:

Specifically, you can do it right here:

https://github.com/named-data-ndnSIM/NFD/blob/bd8eea71137bc382fe1fb8225334b926a5484527/daemon/fw/forwarder.cpp#L148

As far as your second question is concerned, it is feasible to do it. You can add a counter variable to the forwarder class of NFD to figure out how many times you retrieved the same data packet from a node cache.

Hope that this helps!

I was quite interested in this as well. This way contents can have
different sizes and chunks where different chunks can be downloaded and
reordered at the receiver. If this can already be done can that would be
great to know.

Thanks!

Hi guys,

you can simulate this behavior, that is you can extend the producer application to produce chunks of varying size or even schedule events for sending data packets if you want to simulate the delay of fetching data from a disk or a repo. You can also create a big buffer, create and sign data in advance to ?simulate? the disk storage.

It is kind of hard to access parts of the physical file system though, since all the application instances share the same local file system (this is imposed by NS3). You can still do it, but you have to be really careful and make sure that you access unique parts of the file system.

Hope that this helps!

Message-ID: <CAO1+r1OvvieOm6WkWAbo2Jc6dCT4rW-AdibYW9App=Y==ufQVA@mail.gmail.com>

Hello everyone,

There is a very nice NS-3 module called EvalVid which allows for a video
trace file to be sent and received in order to reproduce and simulate the
quality of the receiving video stream in a particular environment. Can this
or something similar be simulated within ndnsim?

Any suggestions would be great.

-Thanks

Hi,

we do not officially support this module. However, a large number of NS3 modules can be treated as regular C++ classes and objects of those classes can be created.

If this is the case, chances are that you might be able to use this module in your simulations.

Message-ID: <CADAVUiHUgrQ2G=amXYgnVJPcW0CJK+H+4_5PJcmTKhzc8n821A@mail.gmail.com>

Dear All,

I would like to try an idea where the consumers first try to
discover the available content providers, then get the content
from one of the providers sending the actual request packets.

Here is my thoughts:

I have added one field to the interest packet to indicate the
type of the interest : discover or request

I have added one field to the data packet to indicate the type

of the data packet : content-offer or content-real

content-offer is same as content-real except the content field is empty.

Now, please help me to identify what other things do I need to do to make
my changes work especially in the consumer and producer files.

Thanking in advance

Thanks for your help. I went ahead and created the classes for this
particular module. Since this is an ns3 module that is based on the
UdpSocketFactory I am trying to rewrite it for ndnsim. I seem to be stuck
on a minor detail. Since the module is based on UDP, a stream of packets is
sent by the server based on a single initial request from the client. Is
there an equivalent behavior within ndnsim? The reason I ask is because
after modifying the module to work with ndnsim only the first data packet
triggers the OnData function of the consumer. The producer continues to
send the stream of data packets but they do not trigger the OnData function
since naturally, after the initial request, there are no pending interests
for the remaining data packets. In other words, is there a way to request
maybe a range of sequence numbers or to accept data packets even if they
have not been requested yet.

Thanks again!

I think that the behavior he mentioned is -> (Interests from 1, 3 and 4
will reach producers and  Interset from 2 will be served from cache).

I have a node with 3 consumers and 3 interfaces.

Currently, I can trace throughput for an interface only. So I want to show

Let me ask this in a different way. Is it possible with ndnsim to accept
data packets without interest packets? That is, what would be a reasonable
way to implement a UDP equivalent with a single initial interest request
and the acceptance of subsequent stream of data packets?

Thanks!

Hi Hassan,

actually, we used to have an implementation of UDP and TCP interfaces in ndnSIM. However, it is not compatible with versions >= 2.0.

You can take a look here:

https://github.com/named-data-ndnSIM/ndnSIM/tree/master-v1/plugins/ip-faces

This code needs to be modified to be compatible with ndnSIM >= 2.0.

We would be grateful if you could do the modifications and glad to push your code to the master branch, so that other people can use it!

The UPD interface implementation should be (almost) ready:

http://gerrit.named-data.net/#/c/1791/

It would be nice if you could update the code for the IP stack and the TCP interface.

Thanks!

I'm curious: wonder why you need to do the above.
as you know, interest-data exchange is important in NDN, to keep hop-by-hop flow balance (see http://named-data.net/project/ndn-design-principles/ <http://named-data.net/project/ndn-design-principles/>)

Well the Evalvid module that I am trying to port takes, as input, a text
representation of a video file which contains the video frame
type, size and the time interval at which the frame should be sent. I may
be overthinking this a little but implementing this in ndn would require
the sending of the video frame packet upon an interest request which is not
desirable for a time sensitive scenario such as video. I wanted the
consumer to simply request the video file to be streamed once and to
subsequently accept the video frame packets as they arrive at their
scheduled intervals.

Thanks.

How would one do congestion control, if packets flow one-direction only?

Evalvid is based on the UDP transport protocol which traditionally does not
have flow control.

Subject: [ndnSIM]  Visualizer does not work
Message-ID: <CAGyRHp5GNQXBUXNHgqLnk0QsNT-mv=6dWVoi7UuP2FkjV3=rdQ@mail.gmail.com>

Hi everybody,

I've got a weird problem which need your help with it. Actually, my
visualizer in ndnSIM had been working fine till a couple days ago, but now
it does not work. For instance, when I run below example:

./waf --run=ndn-simple --vis

ndnSIM  just compile and run it and no window will open to visualize it.
Now I'm wondering how to solve this problem.

P.S. I've tried all necessary commands, and checked my dependencies and
want to make you sure this problem has not its root in them.

Best

Hi Ahmed,

this is a quite open-ended question about the NDN architecture in general. Currently, there is no way to perform congestion control in NDN. To this end, there is no standardized mechanism for that supported in ndnSIM.

There is some ongoing work from Klaus Schneider from Arizona (cc?d). Hope we will have results soon.

this seems some English expression issue -- there are plenty of ways to perform congestion control (e.g. see some ideas from this paper http://named-data.net/wp-content/uploads/comcom-stateful-forwarding.pdf <http://named-data.net/wp-content/uploads/comcom-stateful-forwarding.pdf>)

I believe Spyros meant that today's NFD implementation has not adopted any specific solutions, hence he has not put a congestion control into ndnSIM. 

Klaus Schneider is working on CC as Spyros already mentioned; a quick google search on "ndn congestion control" also returns lots pointers to the papers on the topic

to the original question:

the question is: what's the cause, right?
e.g.
- if the node is not connected, that's a connect problem
- if there is local connectivity but the network is partitioned, that's a slightly different problem
- if the interest the data does not exist, ideally one should receive an app level NACK as explained in http://named-data.net/wp-content/uploads/2016/01/consumer_producer_communication.pdf <http://named-data.net/wp-content/uploads/2016/01/consumer_producer_communication.pdf> 
- if the named producer does not exists, then it is up to how your strategy works (could generate a "NO ROUTE" NACK)

Thank you all for your replies, I really appreciate it.

I have googled and found some papers but was interested to find out if
there was implementation for those ideas in NDN or ndnSIM.

Another question, NDN is pull based so flow control is controlled by the
receiver but what will happen if the link between source and destination
change bandwidth capacity (2 mega -> 1 mega ) or have data more than it's
capacity (3 mega data request over 2 mega link ) , does data packets gets
dropped and interest re transmitted ? so what is the expected behavior in
NDN and ndnSIM ?

Thanks!
Ahmed

no.
but people can help implement in ndnSIM

"the expected behavior in NDN and ndnSIM" sounds a bit ambiguous.
Lets separate out what can be done from what has been implemented.

NDN's 2-way interest-data exchanges form a feedback loop, enabling intelligent forwarding.
in your above example: the router knows how fast it can pull in data before the BW change, and can notice the failure after the change. The router can try alternative path if one exists, or send a NACK back to the prev hop (wonder if you had taken a look of the paper I pointed to below?  paper http://named-data.net/wp-content/uploads/comcom-stateful-forwarding.pdf <http://named-data.net/wp-content/uploads/comcom-stateful-forwarding.pdf>)

Hi, I have a scenario with multiple consumers. I am looking to capture 
the packet arrival times on the consumers and save them to a file.. how 
do i go about this, thank you.

Hi,

some trivial changes off the top of my head are to add some get and set methods for the new fields (and define the new fields as well). These changes should be made here (and to the corresponding header files):

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

You would also need to modify the wireEncode and wireDecode methods of the Interest and Data class (files mentioned above) to encode and decode the new fields to/from wire format.

When you are done with these changes, you should be able to use the new fields in your applications. You just need to get and set the fields in the way that your approach works (e.g., when you express an Interest in your consumer application set the new field of the interest packet, when you receive an Interest in your producer application read the new field of this packet and add the appropriate field to the data packet etc..).

Please let me know if you need any additional information.

Just a follow-up on this one:

Another way that probably would be simpler is to add your new fields to the name of the Interest and Data packet as new name components. Then, you can handle those components in your application using the API of the Name class provided by the ndn-cxx library:

https://github.com/named-data-ndnSIM/ndn-cxx/blob/ndn-cxx-0.3.4-ndnSIM/src/name.hpp

Hi Roger,

You can simply use NS_LOG and print all information you want. For instance,
assume you're using "ndn-consumer.cc" and "ndn-producer.cc", which are
predefined files under this directory: "src/ndnSIM/apps", as applications
in your scenario. After assigning *consumer* application to you nodes, and
perhaps *producer* application to some other of them, you can type below
command in the bash and run it:

NS_LOG=ndn.Consumer:ndn.Producer ./waf --run [*name of your file*]

Now, you'll see that there are a lot of information printed on your screen
which one of is packet arrival. Here number of your nodes and their
topology is not important, at all. So, for any similar purpose you can
simply use NS_LOG environment variable and print any kind of information on
the screen.

Anyway, if you wanted to save printed lines, you can easily use below
command (according to above example):

NS_LOG=ndn.Consumer ./waf --run [*name of your file*] > test.txt

which will save all printed lines in *test.txt* file.

Good luck

Message-ID: <CAO1+r1PBg+c1+oGjCGgW6=E0kmeCzX_Cf1dEjL0J4=2b+beucg@mail.gmail.com>

Hello everyone,

I have the following topology:[image: Inline image 2]
"Node51" and "Node52" are connected via WiFi. Whereas "Node51" and "Node50"
are connected via a p2p link. "Node50" is the producer. For some reason
when node "Node52" requests data from the producer "Node50" does not
respond. However, if I make "Node51" the producer the content is delivered
without issue. Does ndnsim not support this particular multihop scenario?
If so, is there a workaround to this as it seems like a very basic and
practical scenario for NDN. Any help would be greatly appreciated.

Actually I'd like to revise my previous message. This topology works fine,
however, the only issue is if I add a WiFi net device to "Node50" for when
"Node52" associates with "Node50" data should be delivered to "Node52" via
WiFi. Is this possible?

Dear Spyridon,
Many thanks for both the options. Though, I mentioned about the first
option in my last mail but later I did something that exactly matches with
your second solution. It is worthy to mention that I pick this idea from
one of your early solutions for me on some other topics. However, I am
having problem with how to start the retransmission timer for an interest
packet since each interest packet is sent twice now. To be exact, an
interest packet(DISCOVER) for seq1 is first broadcasted to discover
available producers or content routers having the the data for seq1. Once
the available options are discovered then the interest packet (REQUEST) is
unicasted to the best producer or router. Thus, I need

(i) some advice on how can I manage the sequencing and retransmission
timeouts in the consumer file
(ii) how to update the fib/pit while the DISCOVER packet is coming back on
the reverse path.

Thanks in advance

Asif

Hi Hassan,
 
I don't see why it's not possible. If Node50 receives interest on wifi face(WifiNetDevice), it can answer regardless of knowing who has requested on that face.
 
Thanks,
Sabet

Hi Asif,

the internal face is the face that NFD uses to communicate with its managers (used for command Interests). You can think of the netDeviceFace as the network layer interfaces of a router. The ndnFace refers to the ndnSIM specific implementation of the ndn-cxx face. The appFace refers to the face of an ndnSIM application receiving Data and Interest packets. The face ids are used to distinguish among the different faces. You can take a look here as well:

http://ndnsim.net/2.1/metric.html

What application you were running when you obtained this trace file?

Thanks,

Thanks Sabet!

So your suggestions finally worked. I tried multicast before but it would
not work.  Setting the forwarding strategy to multicast AND setting
ndnGlobalRoutingHelper.AddOrigins(all nodes) fixes this issue. I guess the
unfortunate question remains, does this mean I will not be able to use a
best-route forwarding strategy for this scenario? Or is there a way around
this? I essentially want best-route to be used only for the p2p links.

Thanks Spyridon for the explanation. However, I was running a 49 node grid
topology (with ConsumerCbr). By the way, did you thought about the
sequencing and retransmission of my DISCOVER-REQUEST interest issue?

Hi Spyros,

I was curious to know if those topology diagrams were created manually or
were they created by some 'R'script? I could generate some of the graphs
using the provided Rscripts though.

No, the topology diagrams on ndnsim.net <http://ndnsim.net/> website are created manually using aafig module (ascii art to svg converter).  You can see the source code of the pages here http://ndnsim.net/2.1/_sources/metric.txt <http://ndnsim.net/2.1/_sources/metric.txt> or in github repo.  For large topologies, it is better to use graphviz dot (neato, twopi, circo, fdp, or sfdp) tool to visualize arbitrary topologies.  For example, you could use AnnotatedTopology:: SaveGraphviz method (http://ndnsim.net/2.1/doxygen/classns3_1_1AnnotatedTopologyReader.html#a2078a690442885c1c3e2ae5fd9c83895 <http://ndnsim.net/2.1/doxygen/classns3_1_1AnnotatedTopologyReader.html#a2078a690442885c1c3e2ae5fd9c83895>) or create it manually.

Hi Asif,

I do not see anything particularly wrong with sequencing and retransmissions, since the two different kinds of Interests have different names:

You can assign sequence numbers independently to each different Interest category and also handle the Interest retransmission in a different way for each case if that is what you want.

Moreover, there should be no way for you to update the PIT manually. This will take place based on the principles of the architecture/protocol. However, you can install different FIB entries and forwarding strategy for each Interest category to achieve the behavior that you mentioned. You could use the FIB helper:

http://ndnsim.net/2.1/helpers.html#manually-routes-fib-helper <http://ndnsim.net/2.1/helpers.html#manually-routes-fib-helper>

and the strategy choice helper:

http://ndnsim.net/2.1/helpers.html#forwarding-strategy <http://ndnsim.net/2.1/helpers.html#forwarding-strategy>

Hope that this helps.

It is worthy to mention that I pick this idea from one of your early solutions for me on some other topics. However, I am having problem with how to start the retransmission timer for an interest packet since each interest packet is sent twice now. To be exact, an interest packet(DISCOVER) for seq1 is first broadcasted to discover available producers or content routers having the the data for seq1. Once the available options are discovered then the interest packet (REQUEST) is unicasted to the best producer or router. Thus, I need

Hello everyone,

You can also use the available trace files. Look at this
<http://ndnsim.net/2.0/metric.html#application-level-trace-helper>. In this
file, collected during your simulation, you can see the Round Trip Time
(RTT) of every transmitted Interest and its Data packet.

Subject: [ndnSIM] Get the rate of packets and set the rate limit in ndnSIM2.1
Message-ID: <56F8F5E0.9000701@gmail.com>

Dear ALL,

While I am trying to implement my own forwarding strategy, I encounter 
the following problems:
1. I was wondering how can I get the rate (or estimated rate) of packets 
for each name prefix at every face.
2. In ndnSIM 2.1, I cannot find the Class LimitsRate which exists in 
ndnSIM 1.0, I wonder how can I set the rate limit for each name prefix 
at each face.

I am looking forward to your help.

Thanks in advance!

Hi Weihong

In your strategy,
define the granularity of each name prefix: do you take the FIB entry as a ?name prefix?, or something else?
implement an algorithm to estimate the packet rate under the name prefix
store the estimation in the measurements table
Read NFD developer guide ?strategy API? section for more information.

Yours, Junxiao

Message-ID: <4AC03A6244C3C34BB52A7EC60B799C4C03CC2A0E@m-pdc.sbu.ac.ir>

Hi everyone

Is there any resolver for delegation lists in ndnSIM? I mean something like dns(ndns maybe?) which a consumer queries a prefix(say /A) from it and find out about the associated delegation list to /A.
I've seen addDelegation, getDelegations, and other functions related to Link object in doxygen. Where(in which entity) do they save link objects or retrieve them?

Thanks,
Sabet

Hi Sabet, 

the LINK object is a hint used for Interest forwarding. You can take a look at this paper for the overall design and motivation:

http://named-data.net/wp-content/uploads/2015/03/SNAMP-NDN-Scalability.pdf <http://named-data.net/wp-content/uploads/2015/03/SNAMP-NDN-Scalability.pdf>

There is a partially working NDNS application for ndnSIM that was a project of the first NDN hackathon last September:

https://github.com/spirosmastorakis/ndns-scenario <https://github.com/spirosmastorakis/ndns-scenario>

To be honest, I cannot recall what parts of NDNS have actually been ported to ndnSIM though. You could try it and see if that works for you.

Hope that this helps!

Dear Spyridon,

Thanks so much for your quick response. I will try that.
I'm aware of SNAMP paper. Actually I've followed it from earlier versions. But hadn't found anything about ndns in ndnSIM till now. I've just seen this:
https://github.com/cawka/ndnSIM-ndns
So, maybe I should ask Alex if he could help.

Thanks,
Sabet

Hi All,

This problem still persist for me and I am trying it on Mac.

As discussed on this thread, I extracted the command line from the
build/config.log file. It is compiling "../test.cpp" file, which it
generates on the fly I guess. I am not sure how it picks up the #include
path for cryptopp.hpp, but it is #including the file as
"../../src/ndnSIM/ndn-cxx/src/security/cryptopp.hpp". I verified and this
path is actually from ndnSIM's ndn-cxx.  I am not sure why a standalone
ndn-cxx compile would look for ndnSIM.

I think the configure tool is doing all this automatically and we do not
have any control on this. I also tried installing this from the sources but
no success.

/usr/bin/clang++ -pedantic -Wall -O2 -g -std=c++11
-Wno-error=unneeded-internal-declaration -Wno-error=deprecated-register
-Wno-error=unused-local-typedef -stdlib=libc++ -I/usr/include -DNDEBUG

/Users/usrp1/sandbox/ndn-cxx/build/.conf_check_1689d110c002d2313f4665d22885dc23/testbuild/test.cpp.1.o

Can someone guess what is the issue?

I tried compiling the same from the ndn-cxx which is a submodule in ndnSIM
and it gave the same problem there too. According to the file path, the
include path should be - ../../../src/ndnSIM/ndn-cxx/src/security/cryptopp.hpp
instead of ../../src/ndnSIM/ndn-cxx/src/security/cryptopp.hpp

Does this build require to export some env variable before it can be
configured and built?

Hi,

I am not sure if this is the right way, but I figured out a workaround.
Changed the contents of file "ndn-cxx/.waf-tools/cryptopp.py" as follows
(see line #30 below) and it worked.

 29 CRYPTOPP_CHECK_FRAGMENT = '''

 30 #include "../../src/security/cryptopp.hpp"

 31 #include <iostream>

 32

Hope this helps.

/anil.

Hi everyone!

I know that "InterestLifetime" is there, but is there any _TTL_ for
interest messages for scope control ? Does it make sense to have this ?

Thanks.

Subject: [ndnSIM] Problem about logging
Message-ID: <CAKDV_7P--Yq8LhXDVZKQ0+sQE5TnWAFj_M75fLhU2DY5O=-MoQ@mail.gmail.com>

Dear ALL,

I was trying to enable NFD logging in my forwarding strategy, and I had
followed the steps in the NFD developer guide:
1. include core/logger.hpp header file
2. declare logging module using NFD_LOG_INIT("MyStrategy");
3. use NFD_LOG_DEBUG("DEBUG message"); in my source code.
 And I ran the simulation scenarios using the following command:
NS_LOG=nfd.MyStrategy ./waf --run=Mystrategy --vis

However, there is no output of logging information. I was wondering where I
went wrong.
 Thanks in advance.

Yours,
Weihong Yang

Spyridon,

Thank you. You scenario works. Regarding to that, there are questions I need to ask you:
1- What is the content of test.db?
2- What is the procedure to add a zone or identity? I guess there should be some key-chain related routine I'm not familiar with.
3- What is the difference between Name(Name to be resolved) and Hint(Name Hint) in digApp? They are both set to "/ndn"
4- From consumer's perspective, firstly a digApp should query for a "hint" for a prefix, then attach query's answer as a Link object to Interest?
5- What relation is in place between what has been done in your scenario, and Link related functions in ndnSIM?

Many thanks,
Sabet

Hi Sabet, 

the LINK object is a hint used for Interest forwarding. You can take a look at this paper for the overall design and motivation:

http://named-data.net/wp-content/uploads/2015/03/SNAMP-NDN-Scalability.pdf <http://named-data.net/wp-content/uploads/2015/03/SNAMP-NDN-Scalability.pdf>

There is a partially working NDNS application for ndnSIM that was a project of the first NDN hackathon last September:

https://github.com/spirosmastorakis/ndns-scenario <https://github.com/spirosmastorakis/ndns-scenario>

To be honest, I cannot recall what parts of NDNS have actually been ported to ndnSIM though. You could try it and see if that works for you.

Hope that this helps!

Subject: [ndnSIM] Multicast Strategy , strange behavior
Message-ID: <CA+Wzd2Bv9SXaoYxQOq8ONZjOOa9xsboO1RZwynEduhykQz55JQ@mail.gmail.com>

Hi All,

I am using the following topology to try multicast strategy (broadcast). So
I noticed that all requests are broadcasted but I am receiving only replies
from one link (client->R3->Backbone).




??
When I increase the delay on one of the other two links during the
simulation, I start receiving data replies on them also.

I am assuming that on the intersection node (backbone) something stop data
replication on the three interfaces and when there is a delay between
interests this stop doesn't work.

Can someone guide me, on what is happening here and why no data replication
happening from the start ?

Thanks!
Ahmed

Hi Ahmed

After an Interest is multicasted onto multiple paths but those paths join
at an upstream ("backbone" in the topology), the upstream would detect that
the Interests have duplicate Nonce and suppress all but the first Interest,
and send back the Data only along the path on which the Interest arrives
first.

Duplicate Nonce detection is done through the PIT entry and the Dead Nonce
List. See NFD Developer Guide "Forwarding - incoming Interest pipeline" and
"Tables - Dead Nonce List" sections for more information.
Detection through PIT entry is reliable: it can catch every incoming
Interest with duplicate Nonce and suppress it, as long as the PIT entry
still exists. A PIT entry stays for about 100ms after the Interest is
satisfied ("straggler timer"). When the three paths in the topology have
the same or almost same delay, it's almost guaranteed that the PIT entry
exists when the second and third Interest arrive, and thus they are
suppressed.

Detection through Dead Nonce List is selective: it's only used to prevent
"persistent loop" (NFD Bug 1953).
When the second and third paths have a delay that is more than 100ms longer
than the delay of the first path, the duplicate Nonce cannot be detected by
throug the PIT entry, and is usually not detected by the Dead Nonce List.
In this case, the Interest would be permitted to lookup the ContentStore,
find a match, and the cached Data is sent back.

Yours, Junxiao

Thank you Junxiao for the detailed and quick answer.

1- Is there a way to turn off this feature to test the broadcast strategy ?
I tried to set :

*const time::nanoseconds DeadNonceList::DEFAULT_LIFETIME =
time::milliseconds(1);*

but didn't do the trick. It seem the only way is that there should be a
delay on the links from the start so interests don't arrive in parallel.

2- What if there are two clients contacting the server asking for the same
content (same interest) at the same time, this mean only one of them will
get the content as backbone router will suppress one of them.

Thanks!
Ahmed

Hi Ahmed

The multicast strategy is operating correctly when it forwards the Interest
toward all available upstream faces unless it's the sole downstream or
violates scope.
Whether the Data comes back or not has nothing to do with the correctness
of multicast strategy.

DeadNonceList entry lifetime is irrelevant because suppression occurs in
PIT entry, not in DNL.


When multiple consumers are expressing Interests with the same Name,
Selectors, and Link object (or absence of Link object), those Interests are
expected to carry distinct Nonces. See NDN Packet Format spec, Interest -
Nonce section. Those Interests will not be suppressed by duplication Nonce
detection because the Nonce is not duplicate.

Yours, Junxiao

Please see my answer inline. I am not that familiar with the NDNS implementation, so I will try to answer the questions that I know in the best possible way:

> Thank you. You scenario works. Regarding to that, there are questions I need to ask you:
> 1- What is the content of test.db?
> 
It is the database of the current NDNS instance (storing the records).

> 2- What is the procedure to add a zone or identity? I guess there should be some key-chain related routine I'm not familiar with.
> 
I think that this has to do with this file:

https://github.com/spirosmastorakis/ndns-scenario/blob/master/extensions/ndns-create-zone.hpp
> 3- What is the difference between Name(Name to be resolved) and Hint(Name Hint) in digApp? They are both set to "/ndn?
> 
According to the SNAMP paper, a name of some data should be resolved directly to a LINK object that contains a number of globally routable name (forwarding hints). In the current implementation, I think that the name of some data is resolved to a globally routable name directly.
> 4- From consumer's perspective, firstly a digApp should query for a "hint" for a prefix, then attach query's answer as a Link object to Interest?
> 
In theory, the application should retrieve the LINK object directly from NDNS. However, in this case you are right.
> 5- What relation is in place between what has been done in your scenario, and Link related functions in ndnSIM?
> 
Sorry, but I do not understand the question.

NDNS was Alex?s thesis, so he can elaborate more on the implementation details. Hope that my answer helped though.

IP used TTL for scope control, but that is rather implicit, difficult to control.
NDN names are expressive.  NDN tries to use names to control scoping in an explicit way (e.g. local hub)

That's what I thought but for some reason there seems to be a forwarding/
Wifi issue that I can't seem to solve. I'm not sure what the source of the
problem is so I simplified my topology in order to see if the problem
persists and it does. My simplified topology is below:

[image: Inline image 2]

Nodes 0-3 are connected to each other via p2p links. Each of them also have
a Wifi device for node 4 to associate with. When node 4 is associated with
node 0 it is not able to retrieve data from the producer on node 3. Only
when it is associated with node 2 is it able to retrieve data from node 3:

[image: Inline image 4]

Strangely, removing the Wifi devices from all the nodes except for node 0
allows for node 4 to retrieve data from the producer when it is associated
with node 0:

[image: Inline image 5]

This has puzzled me for the past two days. I have set up the NDN stack and
routing as done in the examples:

   //Install NDN stack on all nodes
  NS_LOG_UNCOND ("Install NDN Stack to Nodes.");
  ndn::StackHelper ndnHelper;
  ndnHelper.SetDefaultRoutes(true);
  ndnHelper.setCsSize(10);
  ndnHelper.InstallAll();

  //Choosing forwarding strategy
  NS_LOG_UNCOND ("Installing NDN forwarding strategy.");
  ndn::StrategyChoiceHelper::InstallAll("/myprefix",
"/localhost/nfd/strategy/best-route");

  NS_LOG_UNCOND ("Initialize Global Routing.");
  ndn::GlobalRoutingHelper ndnGlobalRoutingHelper;
  ndnGlobalRoutingHelper.InstallAll();

  ndnGlobalRoutingHelper.AddOrigins("/myprefix", grid.GetNode(0,3));
  ndn::GlobalRoutingHelper::CalculateRoutes();

Are there additional configurations that I may have missed?

Thanks!

Hmmm.
I suggest testing 2 more things.
1- Set forwarding strategy to multicast
2- Manually AddOrigin to the producer for requester and intermediate nodes.
Where is your producer application(responsible for "/myprefix") has been set?

That's what I thought but for some reason there seems to be a forwarding/ Wifi issue that I can't seem to solve. I'm not sure what the source of the problem is so I simplified my topology in order to see if the problem persists and it does. My simplified topology is below: 

 Inline image 2<https://webmail.sbu.ac.ir/Exchange/M.AbdollahiSabet/Drafts/image.png> 


Nodes 0-3 are connected to each other via p2p links. Each of them also have a Wifi device for node 4 to associate with. When node 4 is associated with node 0 it is not able to retrieve data from the producer on node 3. Only when it is associated with node 2 is it able to retrieve data from node 3:

Strangely, removing the Wifi devices from all the nodes except for node 0 allows for node 4 to retrieve data from the producer when it is associated with node 0:

This has puzzled me for the past two days. I have set up the NDN stack and routing as done in the examples:

   //Install NDN stack on all nodes
  NS_LOG_UNCOND ("Install NDN Stack to Nodes.");
  ndn::StackHelper ndnHelper;
  ndnHelper.SetDefaultRoutes(true);
  ndnHelper.setCsSize(10);
  ndnHelper.InstallAll();

  //Choosing forwarding strategy
  NS_LOG_UNCOND ("Installing NDN forwarding strategy.");
  ndn::StrategyChoiceHelper::InstallAll("/myprefix", "/localhost/nfd/strategy/best-route");

  NS_LOG_UNCOND ("Initialize Global Routing.");
  ndn::GlobalRoutingHelper ndnGlobalRoutingHelper;
  ndnGlobalRoutingHelper.InstallAll();

  ndnGlobalRoutingHelper.AddOrigins("/myprefix", grid.GetNode(0,3));
  ndn::GlobalRoutingHelper::CalculateRoutes();

Are there additional configurations that I may have missed?

Thanks!

	Hi Hassan,
	 
	I don't see why it's not possible. If Node50 receives interest on wifi face(WifiNetDevice), it can answer regardless of knowing who has requested on that face.
	 
	Thanks,

	Actually I'd like to revise my previous message. This topology works fine, however, the only issue is if I add a WiFi net device to "Node50" for when "Node52" associates with "Node50" data should be delivered to "Node52" via WiFi. Is this possible?

		Hello everyone, 

		I have the following topology:Inline image 2
		"Node51" and "Node52" are connected via WiFi. Whereas "Node51" and "Node50" are connected via a p2p link. "Node50" is the producer. For some reason when node "Node52" requests data from the producer "Node50" does not respond. However, if I make "Node51" the producer the content is delivered without issue. Does ndnsim not support this particular multihop scenario? If so, is there a workaround to this as it seems like a very basic and practical scenario for NDN. Any help would be greatly appreciated.
