Subject: [ndnSIM] Sending extra interest to just neighbor nodes
Message-ID: <5571AAE5.2020909@inl.ics.keio.ac.jp>

Dear Alex / Spyridon,

Hopefully you are not too busy at this time. I just discovered that the 
code I used to create extra interest for the same content to be sent to 
neighbor nodes did not work as expected. Originally after the 
PropagateInterest (inFace, interest, pitEntry); code of OnInterest 
function of ndn-forwarding-strategy.cc, I added these lines with the 
hope to send another interest for the same content, but with different 
scope and outgoing face:

interest->SetScope (2);
pitEntry->ClearOutgoing ();
pitEntry->AddOutgoing (<another_out_face>);
PropagateInterest (inFace, interest, pitEntry);

However after this part of code is called, the second call to 
PropagateInterest function (the last line that I added) detects that it 
is a retransmission of interest instead, and I get the -SIGIOT error. (I 
checked the isRetransmitted boolean value in the PropagateInterest 
function and found this error)

To fix this, I first thought about creating another pitEntry requesting 
the same content, but with the new outgoing face and interest scope. 
However, I believe this is not possible because PIT table should not 
contain multiple entries for the same content request.

Then I thought about modifying the existing pitEntry for that particular 
content by adding another outgoing face to its list of outgoing face. 
However, I am not sure what the simulator will behave when it finds 
multiple outgoing faces in its list. Will the node send interests to all 
possible faces in the list of outgoing faces? Also by using this method, 
the PropagateInterest function will be called only once to send 
interests with different scopes. If this is the correct approach, how 
can I set different scopes for interests which are to be forwarded to 
different outgoing faces?

Or if you can suggest other approaches, I will gladly follow those 
suggestions as well. Your kind help is appreciated.

Hi Bouabid,

In general, our ndnSIM website provides some helpful information for new users:

http://ndnsim.net/2.0/

To get familiar with NDN simulations, you may take a look at the simulation examples on the ndnSIM website:

http://ndnsim.net/2.0/examples.html

The next step could be to run these simulation examples and see what will happen.

Message-ID: <CAHVD1iZg8qusJJGWZgnLnoxziiqUf8xM5b+GwhPDHmtAsNofMQ@mail.gmail.com>

Hi,

In one of my simulation scenarios, I need a SDN controller function to
program the NFD e.g. to add prefixes to the FIB.

Is this capability currently available in ndnSIM or may be in ns-3, which
can be used in ndnSIM application logic?

Please also suggest alternatives.

Thanks,

I have been doing simulations based on the example of Wifi in
infrastructure mode, adding the ndn modules developed by your team and I
get the following errors after compilation.



I would also like to ask you if it is possible to run simulation of LTE
based on NDN. I ask you this because I also have been running some scripts
including both technologies but it gives me errors associated with the ndn
module, saying that ndnHelpers cannot we recognized.



I appreciate all the help and hints you could provide me in order to fix
this issues.



Best regards.

Hi Gustavo,

Of course, you can run LTE based on NDN. NDN is a universal network layer protocol, that is anything can run over NDN and NDN can run over anything. You should be able to do so in a way similar to your WiFi scenario. There is also a ndnSIM user that has been working on that and has asked some relevant questions:

http://www.lists.cs.ucla.edu/pipermail/ndnsim/2015-April/001832.html

I think that the third attachment includes a scenario that this user has coded. I suggest that you contact the user directly, so that you could share your experience.

Regarding your WiFi scenario, could you please send me your code as an attachment? I am having a hard time to identify the code lines, since the plain text formatting is not working well.

Thank you.

Hi Anil,

to the best of my knowledge, you can use the OpenFlow protocol by attaching it as a module to NS3. Probably, this link can help:

https://www.nsnam.org/docs/release/3.13/models/html/openflow-switch.html

The SDN controller could use the FIB helper to add prefixes to the desired NFD FIBs.

Another alternative could be to create a dedicated node running a SDN controller application that you will code and then modify the forwarding pipelines of NFD to send Interests to the controller in order to perform the desired processing.

Message-ID: <CAM3J8PqjctrtrE+TdKwXaLn+hZ_8vHrVnQxoNNx+QffH4YEVaQ@mail.gmail.com>

Hi,
I want to get the data stored into the CS.I'm using ndnSim 2.0 and I found
a method called getData in the class ndn-contentStore.cpp.

http://ndnsim.net/2.0/doxygen/classns3_1_1ndn_1_1cs_1_1Entry.html

How can I use this method to getData.
thnx a lot for help.

Hi Spyros,Could you please add a scenario/example to show how we can use the class "model/ndn-net-device-face.cpp" for using NDN over L2 frames in ndnSIM environment for educational purposes?I asked from many registered students in this email-group, and they also wanted to know about this important feature in ndnSIM. Thank you in advance for your support.

Best Regards,Armin

ndnSIM already works directly on top of L2 frames, be it PPP frames with PointToPoint channels and network devices or any other type of channels. ? Take a look into model/ndn-net-device-face.cpp for more details.

Message-ID: <CAGCGGjY2hHtVhzayxT2b+Fm_9DNx=ntsZV_h9Km0bGJ+z1yHhw@mail.gmail.com>

Hello Guys,

Do we have a function in NFD at app level such as InterestTimeOut()? like
if I send an interest and if we didn't get any response of that interest
then we should get a notification (event) InterestTimeOut.

I could see a function in NDN face, (ndn-cxx/face.hpp)

  const PendingInterestId*
  expressInterest(const Interest& interest,
                  const OnData& onData, const OnTimeout& onTimeout =
OnTimeout());

But don't know how to use it or call NDF app level

Thanks for the input.

Thanks,
Hitesh

Hi Gustavo,

please use the ?reply to all? option, so that our email exchange is visible to all the users, as some of them may have a similar question.

The thing I meant is that I can see the compilation errors, but if you do not send me the source code itself as a .cpp file, I am not able to see the line numbers, so that to identify directly where the errors occur. :)

Could you please send me the scenario as a .cpp file?

Thanks.

Hi Imen,

I would suggest that you use the find method instead (it is the highest level API call that we have) in a way similar to the one shown here:

https://github.com/NDN-Routing/ndnSIM/blob/master/NFD/daemon/fw/forwarder.cpp#L99-L102

Please let me know if you need any further help.

Hi Hitesh,

NFD is the NDN Forwarder, that is it operates somewhere between the Link and Network layers.

As far as the application layer timeouts, you should modify the code of the consumer application under the "/apps? directory (or create your own consumer application). Specifically, for this purpose, we have the OnTimeout method and some other methods to handle the retransmission timer (e.g., GetRetxTimer, CheckRetxTimeout, SetRetxTimer):

http://ndnsim.net/2.0/doxygen/classns3_1_1ndn_1_1Consumer.html#a5f4e5baddcb70c734c3c92e7bb4d6f38
https://github.com/NDN-Routing/ndnSIM/blob/master/apps/ndn-consumer.cpp

Hope that this helps.

Hi Spyros,I have a network working in L2 as TSN (time-sensitive networking) which consists of real-time Ethernet frames.Now, I am going to transfer its frames through NDN. So, could you please give me some clues?

Good morning Spyridon,

Finally I could solve the issue. It was a problem related with the main
syntaxis at the end of the script. Now I have been able to run the Wifi
simulation in infrastructure mode using ndn.

Thank you very much for your support.

Regards.

Thank you Spyridon.

I have gone through all these. However, they are tracking interest based on
sequence number, same case for OnTimeout as well. In my case, I am not
generating any sequences, its simple interest to neighbor.
Let me explain my thought,

I already customized consumer app to simple interest to neighbor without
any sequences, so I am simple looking an event for OnTimeout where it will
tell me which interest for it timed out rather than sequence number.

For instance, event would be called,
OnTimeout(shared_ptr<const Interest> interest);

Please correct me if I am wrong or going other direction.

Regards,
Hitesh

Hi Hitesh,

if this approach works for you, I do not see any reasons not to use it. :)

Let me elaborate on the sequence number a little bit:

the sequence number is just a way to distinguish among the multiple segments of a file (i.e., name prefix ? at least that is the way I think of it). You can keep the sequence number and remove it after the transmission using the the getPrefix method of the name class:

http://named-data.net/doc/ndn-cxx/current/doxygen/da/d3e/classndn_1_1Name.html#accf5de89558b3bd59a009cb74ceccb4d

We used the sequence number as a way to specify which segment of the file has not been retrieved and request again only the specific segment. If you are planning to retrieve a single data packet for each name prefix, then you do not need a sequence number.

In general, I do not see the sequence number as a limitation or problem, as: 1) it can be removed/added any time, 2) the Interest forwarding is being performed based on the longest name prefix match principle.

That's really great explanation Spyridon. I got a small picture about
sequence :).

Let me think how to incorporate it.

Also, I am still searching or exploring how to use OnTime with interest
name packet approach. I  will update you based on my solution.

Hitesh

Hello.

How can I get the full prefix name in insert method in lru-policy.hpp?

insert(typename parent_trie::iterator item)

*item returns just behind of full prefix that is some kind of %FE%07 if
/prefix1/%FE%07.


Best regards.

Message-ID: <CAGcped2XjUCZbV0BSEMAZm-zSR1bdvig_hVq+a=bN+GzyZnO_Q@mail.gmail.com>

Hi all,

I am re-coding a project that I did with CCNx 0.8.2 into NDN. Checking the
NFD code, I realized that I need to modify the NFD's forwarder
(forwarder.cpp). I am considering writing and testing my code with ndnSIM,
and, when it is stable, I would probably need to move to NFD to test in a
real scenario.

Before starting to code, I would like to know if there is any way to
configure ndnSIM to use a standalone version of NFD, as it does with
ndn-cxx? This will save me some work in the future.

Many thanks and best regards,

Jonnahtan Saltarin.

Hi Jonnahtan,

Unfortunately, ndnSIM has to use a slightly modified version of NFD (some of the behavior must be changed, specifically anything related to real time and real interface operations).

As of right now, NFD is embedded inside the ndnSIM codebase, and we almost finished in a slightly different arrangement where NFD is a git submodule inside ndnSIM.  This would simplify your task, but still would require additional cherry-pikcing of commits from one branch (ndnSIM) to master branch.

Hi Hisham,

Sorry for the delayed reply.  Is your simulation scenario written in c++ or python?  Also, how do you run the simulation?  If with ./waf --run, then the python you see is probably related to this part.

Hi,
My program is in C++.
Is there another method to run my program?  Is it more efficient?

It is not question of efficiency.  Either way it would be the same (the other way is directly running scenario binary from ./build folder).  Running with ./waf --run just has overhead in the beginning of the simulation, as it checks that the latest code is compiled.  It has no effect on later simulation.

Dear Chaim,

To make it compile, you just need to recompile ndn-cxx library as a shared library (this was a recent change in order to avoid several problem caused by the static library):

// clone ndn-cxx
./waf configure --enable-shared --disable-static
./waf
sudo ./waf install


Then reconfigure/build ndnSIM as usual.

Subject: [ndnSIM] Simulation error with NDN over Wireless
Message-ID: <CAF_z9ZJQE9AwoWkB1uptJa-fumvRQr9C0wqBnQ3u0inS5Cs+iw@mail.gmail.com>

Hello,

I am having a problem when I run a simulation of two wired nodes and an
access point with two nodes attached. The simulation is based on ndn but
when I try to check the transmitted and received packets in the python
interface in the access point node and in the other two wired ones the
simulation stops suddenly. The error is described below.

I have checked and it seems to be a bug (bug#1273).

I would really appreciate your help to try to solve this issue.

Regards.

Hi Gustavo,

please when you want us to review some code, include the source file as an attachment. 

When you mentioned bug #1273, do you refer to NS3?

Thank you.

Sorry Spyridon,

next time I will do it as you suggest.

I am getting the same problem reported in this website
http://redmine.named-data.net/issues/1273 .

Please let me know if I should modify something in order to fix this issue.

Regards.

this bug was closed a year ago and it was not related to ndnSIM.

In any case, I do not think that this is related to your case.

Hi Trade,

you do not need to use openssl.

ndnSIM uses ndn-cxx that implements its own crypto primitives.

Hi,

you can take a look at this example:

https://github.com/NDN-Routing/ndnSIM/blob/master/examples/ndn-simple-wifi.cpp

The mobility model for this case is constant, but you can use another one. There are some mobility models offered by NS3.

You may take a look at the NS3 documentation:

https://www.nsnam.org/docs/models/html/mobility.html

Hope that this helps.

Spyridon but do you know what could be the reason of the problem in my
simulation??

Everytime that I try to run it starts without any problem but when I try to
check in the node the flow of interests and contents. It works in the nodes
attached to the wireless AP but if I want to check the same in the wireless
AP node, p2p node and csma node the program stops suddenly and shows me the
following error:



*terminate called after throwing an instance of 'ndn::tlv::Error'  what():
Empty buffer during TLV processingCommand
['/root/ndnSIM/ns-3/build/**scratch/sim05_1',
'--**SimulatorImplementationType=**ns3::VisualSimulatorImpl'] terminated
with signal SIGIOT. Run it under a debugger to get more information (./waf
--run <program> --command-template="gdb --args %s <args>").*

If you could provide me some hints to fix it I would appreciate it.

Regards.

You could run the debugger and find where the exact runtime error occurs and what exactly this error is.

Moreover, you could use the tracers instead of the visualizer. The particular visualizer is a very unstable component of NS3.

Subject: [ndnSIM] Full name requested,
	but Data packet does not have wire format error
Message-ID: <CACfwXDY0Ls0zB24SjTX4-fMkb+0UW94MQdScqd4JjnzK3xtwog@mail.gmail.com>

Hello all,

?I am simulating a simple producer/consumer scenario with
2914.r0-conv-annotated topology and I am getting the following error:?

terminate called after throwing an instance of 'ndn::Data::Error'
  what():  Full name requested, but Data packet does not have wire format
(e.g., not signed)

This error happens when the same consumer requests the same file in a short
period of time.

I found a related problem here
http://gerrit.named-data.net/#/c/1484/1/tests/other/cs-smoketest.cpp but I
am not sure how to solve my problem with this information. I am using
ndnSim 2.0. Could you help me?

Thanks in advance,
Elisa

Hi Elisa,

as it is mentioned in the error message, the data packets may have not
been signed properly or their wire format has not been created properly.

Do you have any specific reasons that you would like to acquire the full
name of a data packet? Have you modified any parts of the ndnSIM codebase?

Thanks,
Spyros

Hi Spyros,

Thank you for your hint. I've managed to isolate the problem, now I wonder
if you have some thoughts on how to fix it. Here is what is happening:

I am changing signature field in each Data packet to match nonce value of
its Interest (it is a workaround I need). I am placing this code on
forwarder.cc, Forwarder::onIncomingInterest(Face& inFace, const Interest&
interest) method, before the node send data to face in case of a cache hit:

ndn::Signature signature;
ndn::SignatureInfo signatureInfo(static_cast<
::ndn::tlv::SignatureTypeValue>(interest.getNonce()));

signature.setInfo(signatureInfo);
signature.setValue(Block(interest.getNonce()));

I am doing something wrong here, since I've commented these lines and the
error is gone. Do you spot anything unusual?

Thanks!

Hi All,


Is there any way to manually "on/off/disable/enable" faces from application
for a particular time or event?


Any suggestion will be appreciated.


Thanks,

Check http://ndnsim.net/2.0/helpers.html#link-control-helper <http://ndnsim.net/2.0/helpers.html#link-control-helper>

This can emulate link going down/up.

Dear all,

 

the problem of "error while loading shared libraries: libndn-cxx.so.0.3.2:
cannot open shared object file: No such file or directory" can be easily
fixed by editing ndnSIM wscript (usually found in ns-3/src/ndnSIM). Locate
the line with "conf.check_cfg(package='libndn-cxx'.. ( see
https://github.com/named-data/ndnSIM/blob/master/wscript#L31 ) and below
that line append the following code:

 

conf.env.append_value('NS3_MODULE_PATH',conf.env['LIBPATH_NDN_CXX'])

 

The same fix should be working for the scenario template, though I haven't
been able to verify that yet.

 

Alternatively, modifying your LD_LIBRARY_PATH appropriately should work too.

Dear All,

I want to check PIT list when data arrive to the router.
So I added 2 lines to the onIncomingData part in forwarder.cpp.

  const nfd::Pit::const_iterator pit_iterator = m_pit.begin();
  const pit::InRecordCollection& inRecords = (*pit_iterator).getInRecords();                

But when I run the ndn-simple scenario, the process was terminated
due to the segmentation fault which caused by getInRecords method. 

Could anyone tell me the appropriate way to check PIT list when data arrive on router?

Thanks,

Ryota Ohnishi

Message-ID: <CAF_z9ZKuU26oO+P1dSDm75aestjKx3LhRzY3xwerrgWz=zpT7A@mail.gmail.com>

Hello,

I have been facing this problem. I have defined the wireless parameters to
define an access point. When I check the interest and data messages in the
wireless network everything is fine.

When I include and connect to the Access Point a wired device through point
to point link the data and interest messages keep going in the network but
if I want to check the traffic that is flowing in each one of the nodes
where the interest and data messages travel, then the simulation stops.

I have also done only telling to the simulator to save the trace of a
certain node in a file but then the simulation stops again.

I suspect that due to a redifinition of the network characteristics of the
node when I set the NetDeviceContainer in which I include the access point
and the wired node  is probably the cause of the problem but I am not sure.

Please could you provide some hints to solve the issue. I have also run the
debugger (gdb tool) and it exits normally without precising any error.

Thanks for your support.

Hello,

if you add these two lines of code at the beginning of the onIncomingData method, you will get a segmentation fault.

I added these two lines at the end of the method and it worked fine. I am not sure why this happens, I will need to take a closer look at it.

As a quick work-around, I would suggest the following:

In order to get the PIT entries that are going to be satisfied by the particular data packet, you can use the following code line (forwarder.cpp:279):

pit::DataMatchResult pitMatches = m_pit.findAllDataMatches(data);

https://github.com/NDN-Routing/ndnSIM/blob/master/NFD/daemon/fw/forwarder.cpp#L279

Afterwards, you can use the two lines of code that you mentioned at the end of the method to get the remaining PIT entries.

Please let me know shall you need anything else.

Thanks.

Hi Gustavo,

to assist you in the best possible way, I would like to know whether you use the visualizer or the command line logs. Moreover, when you said that you print the trace of a certain node, I guess you use our tracers, right?

Thank you.

Hello Spyridon,

I use first the visualizer and the simulation ran without any problem but
when I check each node the simulation stopped. Then I used the ASCII
command and CS and L3 tracers to check what was travelling through the node
but then the simulation crashed again.

Also, if a run the entire topology based on P2P links I don't have any
problem. It is just when P2P and WiFi are present in the same simulation
running ndn.

I appreciate the hints you could give me to solve it.

Regards.

Hmm.. This is the first time I hear about such an issue and I have no idea if it is a ndnSIM-related issue or it is related to NS3.

Could you send me your scenario source code to take a look?

I would suggest that you also send a high-level description to the NS3 mailing list to check with these guys as well.

@Alex: Have you ever experienced such a behavior? Do you have any further clues?

Thanks.

Thank you Alex for the information.

Here is update from me,

I used that function to link down, however, I noticed that, rather just
down the link, its been shutting down source node. For instance,

void ns3::ndn::LinkControlHelper::FailLink(Ptr< Node > node1,Ptr< Node >
node2 )

In above function case, node1, whole node is down not just the link.

Any idea/thought about it?

Thanks !

Regards,
Hitesh

Hi Hitesh,

There was a small bug with LinkControllerHelper implementation that has been fixed in one of the recent commits (https://github.com/NDN-Routing/ndnSIM/commit/da325915a8109979875b214eb2c87678c42fcb21 <https://github.com/NDN-Routing/ndnSIM/commit/da325915a8109979875b214eb2c87678c42fcb21>)

Hello Spyridon,

Thank you for your suggestion to move PIT log code to the other line.
I moved my lines to just below these lines and it worked fine!

	const_cast<Data&>(data).setIncomingFaceId(inFace.getId());	
	++m_counters.getNInDatas();

So that I can now get PIT list in Forwarder.

Thank you again for your advice.

Subject: Re: [ndnSIM] How can I get PIT list in Forwarder?

Hello,

if you add these two lines of code at the beginning of the onIncomingData method, you will get a segmentation fault.

I added these two lines at the end of the method and it worked fine. I am not sure why this happens, I will need to take a closer look at it.

As a quick work-around, I would suggest the following:

In order to get the PIT entries that are going to be satisfied by the particular data packet, you can use the following code line (forwarder.cpp:279):

pit::DataMatchResult pitMatches = m_pit.findAllDataMatches(data);

https://github.com/NDN-Routing/ndnSIM/blob/master/NFD/daemon/fw/forwarder.cpp#L279

Afterwards, you can use the two lines of code that you mentioned at the end of the method to get the remaining PIT entries.

Please let me know shall you need anything else.

Thanks.

Hello Spyridon,

Regarding to the problem I was facing to check the traffic in the nodes it
is partially solved. I recheck the commands used to enable Ascii scripts
and now it works in that way but still failing in the python interface when
you want to check directly on the node during the running simulation.

I want to ask you the following. I have added the two wireless devices in
infrastructure mode. One of them is a consumer and a wired node is the
publisher. My question is why if I don't establish a connection between the
two wireless nodes one of them sends interest to the other one? Default
routes are enables but even when I used a customized forwarding strategy
that still happens. Is that a normal behaviour?

In the attachment you can find the file.

Regards.

Hello.

Can we use ip-based red queue in ndnsim2.0?
I found the example *ndn-grid-topo-plugin-red-queues.cc *in example folder
And the topology is like below:
[Node0       Node1       1Mbps       1       10ms
 ns3::RedQueue,MeanPktSize=100]
I am not sure it is working well now. and how can I designate minth and
maxth in RedQueue? what is the meaning of MeanPktSize?

Best regards.
Wonjun, Choi
