Hi,

as Alex mentioned, we have been trying to reproduce the problem for quite some time.

It would be very helpful if you could share a simple example that causes the problem with us, so that we can take a look.

Thank you,

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.

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.

Hi MD

You may use different name prefixes for each content type.
For example: /org/example/web/ /org/example/video/ /org/example/audio/
/org/example/voice/
Then, grep '/video/' gives you all log lines about video traffic.

If you are using ns-3 tracers, you'll need to modify or configure the
tracer to only collect statistics from names with a certain component. I
don't know how to do this because I don't use them.

Yours, Junxiao

Hi guys! i?m kind of new in ns3 and especially ndnSIM. I would like to run some scenarios with dumbbell topology with ndnstack and a simple cbr application and I will run the exact same scenarios with TCP/IP.
My main concerns are getting the system throughput with l3tracer ,as long as the role and the size of Content Store that I will use. 
Do you have any suggestions on how should i approach the topic? I mean with an interest frequency of 40 interests/sec how much should the size of CS be?

Hi,

I feel that this a research question. It depends on what exactly you are trying to do and what are the goals of your research. Nobody can tell what will be the size of caches when NDN gets extensively deployed.

I think you should experiment with various setups till you get the desired results.

Thanks,

 Content-Store

If you're trying to use an external library, then you need not just put headers in (unless it is just header-only library), but also properly link the library to the code, in this case to ndnSIM module.  You can take a look at examples in wscript in NS-3 folder, examples in waf book, and examples in waf source (the last one, in my opinion, is the best place to look).

Also. Based on the errors, I highly suspect that you not going to succeed in making Redis working with NS-3.  NS-3 is a discrete event simulator that expects that all events are scheduled and processed by the NS-3's Simulator interface.  ev_io_start is part of libev library that implements an even loop.  You can probably make code compile (e.g., by properly linking to libev), but it most likely not going to give you the expected results: some parts of the code will be working with simulated events (simulated time), some parts with real events (real time) with unpredictable interactions.  You can try to replace the even loop in redis library by NS-3's facilities (this is exactly what has been done for ndn-cxx and NFD integration), but it may be a non-trivial task.

Hi


I wonder if in NDN, the packets aggregation is on router-level not publisher-level. ?

By publisher-level, I mean once publisher received two interest packets with the same data  name , it should give two responses.  Is that correct ?


For example

In my simulation, if the publisher receive 100 interest packets with same data name within a short time and the  publisher answers 100 times.


I checked the log file of publisher to confirm the results.

Hi,

the aggregation is being done at each forwarder (NFD instance). 

This might happen if there is no pending interest for the interest name and the data is not cached along the path that the interest arrives at the publisher.

Subject: [ndnSIM] Obtaining Metrics in ndnSIM
Message-ID: <CAL=tGcVMtu+2S1QN94SHHZPDixUWKNcRkn-BsL_g5vYR6ymNJA@mail.gmail.com>

Hello guys!

I am a new user of ns-3 and ndnSIM and I'm facing some problems while
obtaining measurements for my experiments.My main goal is to compare the
network throughput and the app-delays in a dumbbell topology while using
ndn stack on the one hand and the classic TCP/IP architecture on the other.

My main concern is the network throughput measurement. I added the l3
tracer on the ndn-simple scenario and my thoughts are that I should isolate
the InData measurements of all nodes,add them up, and maybe that would
generate the throughput of the network as long as I use the seventh
column(Kilobytes) of the rate-trace.txt file.

Another concern of mine is,how would i get the same network approach in
TCP/IP scenarios. I guess that i should use a TCP Bulk Sender
Application(or an OnOff application since I'm using consumer cbr in ndnSIM)
with the exact same Data rate, with which interests are generated in
ndnSIM. (100 interests/sec --> 100 packets/sec data rate in TCP/IP).

Any advice/comment/correction of the above logic would be extremely helpful!

Thanks in advance for your time!

I get error(CustomTracer not defined) when I use it like

which is same as

I added the l3 tracer on the ndn-simple scenario and my thoughts are that I should isolate the InData measurements of all nodes,add them up, and maybe that would generate the throughput of the network as long as I use the seventh column(Kilobytes) of the rate-trace.txt file.

You can use some trace processing framework to do that (e.g., grep, awk, R). Then, excel or gnuplot to visualize the results.

Subject: [ndnSIM] Missing HopCountTag in Data Packets
Message-ID: <CAM4XVkrM=peRWgwP9x+8SyYhkgBACrUaDqLa8dEFekF6x1oebQ@mail.gmail.com>

Hi All,

I have an ndnSIM topology with one producer, multiple consumers and
intermediate nodes.  I am trying to get the hop count for incoming
data packets at the consumers.

Below are the code and the trace for a single Interest packet.
I confirmed that I am getting data from a different node (node 64)
than the consumer (node 54), so the reply is not from local
cache/local producer.

This is my code  for consumer::onData

________________________ Code  ______________________________________

    void
    onData(const ndn::Interest& interest, const ndn::Data& data)
    {
        auto ID = ns3::Simulator::GetContext();
        auto now = ns3::Simulator::Now().To(ns3::Time::S);

         int hopCount = 0;
         auto hopCountTag = data.getTag<ndn::lp::HopCountTag>();
         if (hopCountTag != nullptr) {
            hopCount = *hopCountTag;
            std::cout << "Hop count: " << *hopCountTag << std::endl;
          }
        else {
            std::cout << "Packet tag doesn't exist for " <<
data.getName() <<  std::endl;
        }
        std::cout << "Time: " << now << ",node:" << ID  <<  "
Consumer:onData"   << ",Data Name "  << data.getName() << ",Hop Count
" << hopCount << std::endl;

        ..............
    }

Thanks Alex,


Do you have any idea to deal with it and simulate Redis with ndnSIM(or something else) ?

Subject: Re: Problem related to ndnSIM with Redis integration in Content-Store

If you're trying to use an external library, then you need not just put headers in (unless it is just header-only library), but also properly link the library to the code, in this case to ndnSIM module.  You can take a look at examples in wscript in NS-3 folder, examples in waf book, and examples in waf source (the last one, in my opinion, is the best place to look).

Also. Based on the errors, I highly suspect that you not going to succeed in making Redis working with NS-3.  NS-3 is a discrete event simulator that expects that all events are scheduled and processed by the NS-3's Simulator interface.  ev_io_start is part of libev library that implements an even loop.  You can probably make code compile (e.g., by properly linking to libev), but it most likely not going to give you the expected results: some parts of the code will be working with simulated events (simulated time), some parts with real events (real time) with unpredictable interactions.  You can try to replace the even loop in redis library by NS-3's facilities (this is exactly what has been done for ndn-cxx and NFD integration), but it may be a non-trivial task.

Hi there,

I am going to replace Table data structure with Redis in-memory database in Content-Store for benchmarking purpose. I have downloaded a C++ client for Redis called Redox that has some .h and .hpp files. I have added #include parts in cs-entry.cpp and run ./waf. But there are some errors following below:

./libns3-dev-ndnSIM-debug.so: undefined reference to `ev_io_start`
./libns3-dev-ndnSIM-debug.so: undefined reference to `redisAsyncHandleRead`
./libns3-dev-ndnSIM-debug.so: undefined reference to `ev_io_stop`
./libns3-dev-ndnSIM-debug.so: undefined reference to `redisAsyncHandleWrite`
`

I figured out that it does not find those headers but I do not know where do I have to put header definition to make './waf' aware of new module. Any idea about this problem? Where should .h and .hpp files be defined? I have defined them in ndn-all.hpp but no hopes.

Thanks for your help.

FYI.  Susmit sent me his code and after a bit of deep debugging, I discovered that this problem was actually caused by a small bug in ndnSIM.  I just pushed a fix to our code review system and it should be merged as soon as all sanity checks passed.

Hi All:


I  can get the queue length from an outface in ndnSIM2.0, but something has changed from the version 2.2, which causes my code does not work. 
In ndnSIM2.0 there are NetDeviceFace, but in version 2.3, this class is replaced with NetDeviceTransport. Now I can not get the queue length from an outFace in ndnSIM2.3?
with my best regardVay

Hi Vay,

It is similar, but just a little bit more indirect:

nfd::Face face;
auto& transport = dynamic_cast<NetDeviceTransport>(face->getTransport())
if (transport != nullptr) {
   transport->GetNetDevice() ...  // and the rest the same as before
}
// else it is not a NetDevice-based face

Sincerely,
Alex

Message-ID: <CAOaFBRUzMzsU8tWZ-SS4yabbVMFRuoAVAq_RAOBhEvfEekmQBg@mail.gmail.com>

Dear all

I want to add a new variable in data.hpp and  create get?set functions.
Then , in ndn-producer.cpp::oninterest , i use set functions like below.

data->setString(str);
//std::cout << data->getString() << std::endl;
I make sure that the str was set.

but , in ndn-consumer.cpp::ondata , i use get functions like below.

std::cout << data->getString() << std::endl;

there is something wrong, str is empty!

why i want to do that is the content may be encoded ,
and the consumer will receive some trash that i dont need.

can someone help me to solve this questions
I need some steps or tips.

My guess that you have missed two more steps while modifying data.cpp. You also need to properly encode and decode your new string to/from wire format.

However, I'm kind of unsure what the problem you referring about receiving trash. The producer app is controlling what is put into the content and in which format.  If you want to publish just a string, you just need to encode and decode it from the content.  If you want to include more content (e.g., to inflate packet size), you can define a small structure on how content part is encoded.

I test the same code on three platfoms like below.

http://imgur.com/a/9e38l

and the first one is mac os, second one is mint based on ubuntu16.04, the
last one is ubuntu16.04 LTS.

the code in ndn-producer is
data->setContent(::ndn::encoding::makeStringBlock(::ndn::tlv::Content,
str));

the code in ndn-consumer is
NS_LOG_INFO("< DATA for " << data->getContent().value());

I dont know what happened on these platforms, the same code ,the different
result. orz

This is not the proper way of interpreting content as a string.  This will try to interpret bytes carried in the content as a null-terminated string, which the content probably isn't.

Use this, a bit more explicit, way:

std::string stringValue(data->getContent().value(), data->getContent().value_size());

Message-ID: <CA+CQka4jfpicN9wyaSCh8hYpnOrRLXsyvEoqni52QT_E4ti_7w@mail.gmail.com>

Dear ndnSIM users

I need to run a topology consisting of a producer, a consumer
and a few routers. I want to use the nlsr as the routing protocol
in this simulation. I know I can use nlsrSIM which is ported by
Anil Jangam into ndnSIM recently but I do not know how exactly I can do it.
I appreciate if anyone help me doing this.

Hello Mahsa,

This scenario of application is not available yet nor tested. Below are
some some directions how it can be done.

As discussed, you will have to install the producer consumer apps on the
nodes along with NLSR and start the producer/consumer application as soon
as you detect that routing has converged. You can start them ahead of
routing convergence but it may not find the routes and traffic may not go
through. Please note that the default routing must disabled when NLSR is
active.

Topic: AppDelay tracer
hi Alex,
ndnsim Appdelaytracer stops writing into the specified file after 5 
seconds.
I am simulating a VANETS scenario using multicast forwarding strategy.

i've called/defined the following virtual function as per the sources:

Simulator::Stop (Seconds (50.0));
AppDelayTracer::InstallAll("3trapptrace.txt")
Simulator::Run ();
Simulator::Destroy ();

Let me know if further details are required to debug this problem.

Regards,
Raj

Hi Raj,

AppDelayTracer add a line into the output only when the client app receives data.  The behavior you observing suggests that your client apps stop receiving data after 5 seconds.

Dear all ndn users


I changed my max packet length ,  but it's something bad happened.

The MCU size is to short.

Where is the MCU attributed variable that I can set?

Thanks

You need to modify MAX_NDN_PACKET_SIZE in
ns-3/src/ndnSIM/ndn-cxx/src/encoding/tlv.hpp

I have already modified it.

But it pop up this message.

assert failed. cond="packet->GetSize() <= m_netDevice->GetMtu()",
msg="Packet size 142480 exceeds device MTU 1500",
file=../src/ndnSIM/model/ndn-net-device-link-service.cpp, line=139
terminate called without an active exception

So , is it have the way to modify MTU size?

For this, you need to set default size of MTU for NS-3's PointToPoint devices:

There are several ways, the simplest one is

  Config::SetDefault("ns3:: PointToPointNetDevice::Mtu", StringValue("65535"));

Message-ID: <58a7a9ff.c1ce620a.77d9.2818@mx.google.com>

ACM ICN 2017 - CALL FOR POSTERS AND DEMOS
4th ACM Conference on Information-Centric Networking
Berlin, Germany on Sep. 26-28, 2017
http://conferences2.sigcomm.org/acm-icn/2017/cf-posters-and-demos.html

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

The ICN poster and demo sessions are intended to showcase works-in-progress. Topics of interest are the same as those listed in the main track call for papers. We strongly encourage both student and industry submissions. Both demos and posters should be accompanied by a two-page extended abstract, which will be published in the conference proceedings.

We specifically encourage submissions of posters and demos that are accompanied with datasets. Such submissions will have a preferential treatment during the review and will be eligible for special awards. The aim is to collect and share datasets that can hopefully become a common ground for evaluation in the ICN community.

The posters and demos submitted to ACM ICN 2017 must be original and cannot be concurrently submitted to other workshops or conferences during the ACM ICN 2017 poster/demo review period. All dual submissions will be rejected without review.

WHY SHOULD YOU SUBMIT A POSTER OR A DEMO?

Presenting a poster is a great opportunity, especially for students, to obtain interesting and valuable feedback on ongoing research from a knowledgeable crowd at the conference. Accepted posters and demos will be published as a two-page abstract for the archived conference proceedings. Students who are submitting posters are highly encouraged to examine if they are eligible for student travel grants.

Subject: [ndnSIM] Best Route acting weird
Message-ID: <CADQ0MFanQCeZRGat+eVK1hAAkToLss+bk-jW+aryeQAn=4FEEg@mail.gmail.com>

?Hi there,

I was trying to show the impact forwarding plane and forwarding strategy in
failure detection with a simple scenario in ndnSIM:

  ndn::FibHelper::AddRoute(nodes.Get(0),ndn::Name("/prefix"),
> nodes.Get(2),1);
>   ndn::FibHelper::AddRoute(nodes.Get(1),ndn::Name("/prefix"),
> nodes.Get(2),20);
>   ndn::FibHelper::AddRoute(nodes.Get(0),ndn::Name("/prefix"),
> nodes.Get(1),20);
>
>   ndn::StrategyChoiceHelper::Install(nodes.Get(0), ndn::Name("/prefix"),
> "/localhost/nfd/strategy/best-route");
>
>   // Consumer
>   ndn::AppHelper consumerHelper("ns3::ndn::ConsumerCbr");
>   consumerHelper.SetPrefix("/prefix");
>   consumerHelper.SetAttribute("Frequency", StringValue("1"));
>   consumerHelper.Install(nodes.Get(0));
>
>   // Producer
>   ndn::AppHelper producerHelper("ns3::ndn::Producer");
>   producerHelper.SetPrefix("/prefix");
>   producerHelper.SetAttribute("PayloadSize", StringValue("1024"));
>   producerHelper.Install(nodes.Get(2));
>
>   Simulator::Schedule(Seconds(3.0), ndn::LinkControlHelper::FailLink,
> nodes.Get(0), nodes.Get(2));
>   Simulator::Schedule(Seconds(15.0), ndn::LinkControlHelper::UpLink,
> nodes.Get(0), nodes.Get(2));
>

It works fine at first and detects the failure so tries with the other face
from 4s to 8s. But After 9s, Consumer tries sending interest while nfd does
not send it:

9s 0 ndn.Consumer:SendPacket()
> 9s 0 ndn.Consumer:SendPacket(): [INFO ] > Interest for 6
> 9s 0 ndn.Consumer:WillSendOutInterest(): [DEBUG] Trying to add 6 with
> +9000000000.0ns. already 0 items
> 10s 0 ndn.Consumer:SendPacket()
> 10s 0 ndn.Consumer:SendPacket(): [INFO ] > Interest for 7
> 10s 0 ndn.Consumer:WillSendOutInterest(): [DEBUG] Trying to add 7 with
> +10000000000.0ns. already 1 items
> 10.6s -1 ndn.Consumer:OnTimeout(6)
> 11s 0 ndn.Consumer:SendPacket()
> 11s 0 ndn.Consumer:SendPacket(): [INFO ] > Interest for 6
> 11s 0 ndn.Consumer:WillSendOutInterest(): [DEBUG] Trying to add 6 with
> +11000000000.0ns. already 1 items
>

 As soon as UpLink event, consumer tries with the first face and retrieves
data. Why is that? Is it a kind of bug in nfd?

Thanks,
Sabet

Anil,

Why is that? I mean if I install and start a producer application on one of
the nodes in ndn-simple-nlsr, why it isn't going to converge the routing
tables? Isn't that why we expect from nlsr?

Hi Sabet

This may be related to the retransmission behavior of ns3::ndn::ConsumerCbr.

I can see that ndn::LinkControlHelper::FailLink does not cause
face->getStatus() to become DOWN, and there is no BFD running, so the face
will remain UP from strategy point of view.
Your scenario uses static routes, so that 0->2 route would remain active
even if the link is having 100% loss rate.
As long as face->getState() is UP and the route is still active, NFD
best-route v4 keeps using 0->2 route when an Interest is received for the
first time, and will try 0->1 route only if the consumer retransmit the
Interest (same Name+Selectors+Link, different Nonce).
Moreover, a consumer retransmission can cause best-route v4 to use 0->2
route only if it arrives no later than InterestLifetime expiration (2
seconds in your scenario), and no earlier than best-route's suppression
timer (10ms for the first retransmission).

ns3::ndn::ConsumerCbr expresses a new Interest every 1 second with
InterestLifetime 2000ms, and retransmits an unsatisfied Interest after RTO.
RTO is computed using TCP's algorithm, bounded between 0.2 and 200 seconds.
When Data arrives, its RTT is added to the RttEstimator if the Interest has
not been retransmitted. On the other hand, if an Interest times out (no
Data within RTO), the RTO multiplier doubles, up to 64. The multiplier can
be reset to 1 only if a Data arrives without any Interest retransmission.
Combine this with the behavior of best-route v4, we can see that, since
best-route v4 requires consumer retransmission for every Interest in order
to retrieve Data via 0->1 route, the multiplier would never get reset.
Eventually, the RTO would exceed InterestLifetime, and therefore the
retransmitted Interest would not be detected by best-route v4 as consumer
retransmission.

Your log shows, Interest for seq 6 is initially sent at 9.0s. RTO timeout
occurs at 10.6s. Then, the logic in ConsumerCbr schedules the
retransmission at 11.0s.
This is exactly the case I described above: at 11.0s, PIT entry is gone
because InterestLifetime has expired, so that best-route v4 would detect
the Interest as a new Interest instead of a retransmission, and forward it
toward 0->2 route which is having 100% loss rate.
This is the expected behavior of best-route v4, and it's not a NFD bug.


To make this scenario work better, suggestions are:

   - Implement BFD in the face, making face->getState() report as DOWN, so
   that strategy would not use the face.
   - Use AccessStrategy, which can switch to 0->1 route if 0->2 isn't
   working. But it won't switch back.
   - Change either InterestLifetime or max RTO, so that max RTO (plus
   ConsumerCbr's scheduling delay) is less than InterestLifetime.


Yours, Junxiao

So, the helper does not really fail a link. Isn't failing/uping a link what
it actually supposed to do?

What is RetxSuppressionExponential? Actually I can see what it does. But,
why is it separated from the strategy itself?

About you suggestion. Do we have any kind of implementation of BFD(rfc
5880/7880) for NDN in any level?

Thanks,
Sabet

Alex,

I can make a copy of Interest and modify it. How can I get it
Forwarder::startProcessInterest to make it pass forwarding pipeline again?
I mean, what about the incoming face? Any suggestion?

Thanks,
Sabet

Hi Sabet


Thank you so much. You're right!! I guess this shows what you said:


> 10s 0 nfd.BestRouteStrategy2:afterReceiveInterest(): [DEBUG]
> /prefix/%FE%07?ndn.InterestLifetime=2000&ndn.Nonce=3530243069 from=259
> newPitEntry-to=257
> 14s 0 nfd.BestRouteStrategy2:afterReceiveInterest(): [DEBUG]
> /prefix/%FE%07?ndn.InterestLifetime=2000&ndn.Nonce=85550101 from=259
> newPitEntry-to=257
>

These two lines clearly indicate the consumer retransmission is treated as
new Interest by best-route v4.

So, the helper does not really fail a link. Isn't failing/uping a link what
it actually supposed to do?

LinkControlHelper fails a link by setting it's loss rate to 100%. This is
correct.
What's missing is: the face state won't report as DOWN. This can be
achieved either by BFD, or by monitoring the underlying transport and
change state directly https://redmine.named-data.net/issues/3352 .
The equivalence of the latter approach in ndnSIM is to set the transport
state as DOWN in LinkControlHelper. Let's see how ndnSIM developers think
about this.

What is RetxSuppressionExponential? Actually I can see what it does. But,
why is it separated from the strategy itself?

RetxSuppression* implements an algorithm to determine whether an incoming
Interest should cause strategy retry or should be aggregated. Too much
retries waste bandwidth; too much aggregation limits the opportunity to
explore alternate paths https://redmine.named-data.net/issues/3889 .
The implementation is in separate classes so that it can be reused across
strategies. However, it should be considered part of the strategy design.


About you suggestion. Do we have any kind of implementation of BFD(rfc
5880/7880) for NDN in any level?

No.

Yours, Junxiao

This line is trying to copy Fib type because 'auto' is deduced as
'nfd::Fib' value type. Change it to 'const nfd::Fib&' and this should
compile.

Hi Sabet

Starting NFD 0.5.0, Strategy::sendInterest function allows the strategy to
directly specify the Interest packet to be sent out, so that you can make a
copy of the Interest and modify it as you need.

auto outInterest = make_shared<Interest>(inInterest);
outInterest->setInterestLifetime(time::milliseconds(500));
this->sendInterest(pitEntry, outFace, *outInterest);

Just make sure the copy of Interest is created in make_shared, and it still
matches the PIT entry which means you can't change Name+Selectors+Link.



I can make a copy of Interest and modify it. How can I get it
Forwarder::startProcessInterest
to make it pass forwarding pipeline again? I mean, what about the incoming
face? Any suggestion?

I don't know why you want the Interest to enter as an incoming Interest.
Where does it come from? (and that will be your incoming face)

Yours, Junxiao

Dear Junxaio,

The point is that I want to substitute Link object. So I need to have the
interest processed again, because this time it will be out of
producerRegion and should be forwarded based on forwarding hint.

Thanks,
Sabet

Hi Sabet

You are actually able to change the Link object from strategy in NFD 0.5.1,
but this is an undocumented feature and can disappear in NFD 0.6.0

Hi Sabet,

I did not say that -- NLSR will converge. I was suggesting it from the
point in your simulation where you start the producer application e.g. if
you start producer, before starting the NLSR application, it may not find
the routes. Hope this clarify your doubt.

 Junxiao,

Could you please refer me to the actual code? To the best of my knowledge,
it is in Forwader::onContentStoreMiss that nfd decides whether to look up
fib with interest's name or with selectedDelegation. So it is before
strategy taking control of forwarding interest.

BTW, for that issue, I guess it would be nicer if every application as soon
as starting, update NRT with its prefix. Furthermore , I believe every
router in a domain should have the same NRT, or at least there must be
certain conjuctions.

Thanks,
Sabet

Anil,

Thanks for the clarification. So if I start a producer app after NLSR
initialization, nlsr will do the convergence. Why not before? I mean If I
start a producer app at 1s and start nlsr at 2s, the node should inform
other routers of the producer prefix, right?

Thanks,
Sabet

Hi Sabet,

What I am trying to say that if you start producer before NLSR app, it may
not find routes as NLSR would still be doing the routing table updates. It
does not mean that it will not allow NLSR to converge. Since I have not yet
tested this scenario myself, I thought to speculate that possibility. I do
not know how ndnSIM scheduler would be scheduling events from two different
ndn applications running on a given node. Let me know how it behaves once
you try it.

OK.

Take ndn-nlsr-simple for example. At first(0s), there is 1 entry in fib of
all nodes. At Seconds(25.0) fib size of nodes are:
node 0 = 12
node 1 = 11
node 2 = 11
node 3 = 10
node 4 = 10

I install and start a ndn::Producer application on nodes.Get(0) at
Seconds(2.0). Again at Seconds(25.0) I have:
 ?
node 0 = 13
node 1 = 11
node 2 = 11
node 3 = 10
node 4 = 10

So I guess the convergence has not happened successfully.

That is it! You're right. Thank you.

This is anyone interested:

printFIB(Ptr<Node> node)
{
    const nfd::Fib& fib =
node->GetObject<ndn::L3Protocol>()->getForwarder()->getFib();
    for (nfd::Fib::const_iterator entry = fib.begin(); entry != fib.end();
entry++)
      cout<<entry->getPrefix()<<std::endl;
    cout<<std::endl;
}

hi Alex,
I have written a new forwarding strategy and
included :
const Name 
ZStrategy::STRATEGY_NAME("ndn:/localhost/nfd/strategy/ZStrategy/%FD%00");
NFD_REGISTER_STRATEGY(ZStrategy);

How do i call it in my main program(#include

1.
StrategyChoiceHelper::InstallAll("/", 
"/localhost/nfd/strategy/ZStrategy");
--------------------------------------------------------------------------------------------------------------
Problem: Can't test if this is implemented or not

OR

2.
StrategyChoiceHelper::Install<nfd::fw::ZStrategy>(nodes,"/");

Where should I change in the ndnSIM code that a node send their current
position to a specific node in the network connecting through
wireless+wired.

Please for God sake Just give me a hint at least.

Hi Naveed,

Can you provide some more details about what you are trying to do? Not
sure I understand the problem.

If your mobile nodes are sending Interests to a specific node, can you
just append the information to Interest name(s)?
Alternately, you could try designing a protocol where the collector
node tries to contact the mobile node through Interest.

Susmit thank you very much for kind reply. I attached scenario pic please
take a look to it. Basically I want that when node 1 move from AP1 to AP2,
the AP2 send the node information to node 2 in the picture. Hope you
understand what I am trying to do.

Hi Naveed,

apologies for the belated response. I have not seen 6 emails from you on the list, are you sure you have sent them to the correct mailing list and not some bounces mailing list?

Anyway, back to your question, as Susmit already pointed out, your question is kind of broad to be given a single answer. There is a number of ways to approach the problem: 1) attach information to Interest name, 2) create an ndnSIM application to do that, 3) change NFD on each node to do that.

You will have to decide which way you would like to go, understand the trade-offs of each approach and then you will have to dive deep into the related parts of the codebase.

Thanks and I am sorry again for the inconvenience,

hi Alex,
I have written a new forwarding strategy and
included :
const Name 
ZStrategy::STRATEGY_NAME("ndn:/localhost/nfd/strategy/ZStrategy/%FD%00");

How do i call it in my main program(#include

OR

Hi,

have you tried to register your strategy like this?

https://github.com/named-data-ndnSIM/NFD/blob/38111cde9bab698f6eaf1a9d430130c2cbb3eca4/daemon/fw/multicast-strategy.cpp#L32-L33 <https://github.com/named-data-ndnSIM/NFD/blob/38111cde9bab698f6eaf1a9d430130c2cbb3eca4/daemon/fw/multicast-strategy.cpp#L32-L33>

hi Spyros,
I have written a new forwarding strategy and
included following in z-strategy.cpp
const Name 
ZStrategy::STRATEGY_NAME("ndn:/localhost/nfd/strategy/ZStrategy/%FD%00");
NFD_REGISTER_STRATEGY(ZStrategy);

after saving the files z-strategy.cpp and z-strategy.hpp in 
/NFD/daemon/fw
i used ./waf
then included the below method in my main(network simulation)program.

How do i call it in my main program(#include 
"NFD/daemon/fw/z-strategy.hpp") that implements this strategy?
1.
StrategyChoiceHelper::InstallAll("/", 
"/localhost/nfd/strategy/ZStrategy");
--------------------------------------------------------------------------------------------------------------

2.
I moved the random-load-balancer-strategy.hpp and

StrategyChoiceHelper::Install<nfd::fw::RandomLoadBalancerStrategy>(nodes,"/");

I tried using:

Subject: [ndnSIM] A question about the expiry of PIT entry
Message-ID: <2017022415594216327025@iie.ac.cn>

Dear all:
     Recently, I wonder about the expiry of PIT entry recorded in the PIT module, and I print the expiry in the Inrecord of each entry by adding print information  in the  "Forwarder::onIncomingInterset()" and move function "compare_InRecord_expiry" ahead to avoid error. I run the "./waf --run ndn-simple" successfully and redirect the output into a text file.
//+++++++++++++++++++++++++++++++++++++++
double tt = ns3::Simulator::Now().ToDouble(ns3::Time::S);
std::cout <<"==========Forwarder::onIncomingInterest==================" << interest.getName().toUri()  << "\t"  << m_pit.size() << std::endl;
auto it = m_pit.begin();
for(it = m_pit.begin(); it != m_pit.end(); it++)
{
        pit::InRecordCollection::iterator lastExpiring = std::max_element(it->in_begin(), it->in_end(), &compare_InRecord_expiry);
        time::nanoseconds time_s = lastExpiring->getExpiry()- time::steady_clock::now();
        std::cout << tt << "\t" << it->getName().toUri() << "\t" <<  time_s << std::endl;
}
//+++++++++++++++++++++++++++++++++++++++
     In general, the expiry should be a non-negetive value since it means the time interval to be expired. However, I find there are negetive values and huge positive values in the result file. As shown below fig. and I doubt the entry satisfied by Data is not clear timely, but I still cannot convince myself. 
    I need your help and looking forward to your reply. Thanks very much.
