Hi Haroon,<br>
<br>
To simulate 5 seconds of network activity, you would want to put Stop(Seconds(5)) in your scenario. How long such a simulation will take depends on many factors, including machine CPU, memory, topology, and the actual scenario. But in any case, even if it takes 3 days to finish, NS-3/ndnSIM will simulate just 5 seconds of the network activity in the scenario you have defined.<br>

Dear All,<br>
<br>
I am curious to know how a distributed application works in CCN paradigm.<br>
Consider a scenario where an application is having three threads (logical<br>
processes) running on three nodes (three processors of a single node). Now,<br>
if these three processes want to communicate with each other for a certain<br>
reason. How can I achieve the same in CCN, i.e., (a) how processes can<br>
refer to each other (NAMING CONCERN) (b) will the format of Interest and<br>
Data packets will be same as that of current packet structure in CCN/NDN.<br>
Since, these communication messages might be very short like Hello packets<br>
or status request of a node.<br>
<br>
<br>
Is there any simple distributed application with which I can start working<br>
and come out with different possibilities of communication between<br>
processes of an application? Furthermore, I would like to mention that I<br>
want do this in ndnSIM. Currently, is there any support (libraries) in<br>
ndnSIM for doing this.<br>
<br>
<br>
Another concern I am thinking is that I know that CCN is pull based<br>
approach. Can I mix a push based approach for some messages in a<br>
distributed scenario discussed above without violating CCN paradigm?<br>
<br>
<br>
Best,<br>

Hi Narjes,<br>
<br>
In which file(s) did you define the new strategies? Are you sure they are compiled together with your scenario?<br>
<br>
I frequently forget to add<br>
<br>
NS_OBJECT_ENSURE_REGISTERED(MyStrategyClass);<br>
<br>
to ensure that the new strategy is registered in NS-3 object system.<br>

I don?t work with CCNx daemon, but with NFD daemon each of your threads can register its own individual name like<br>
1) /chatapp/thread1<br>
2) /chatapp/thread2<br>
3) /chatapp/thread3<br>
<br>
I didn?t understand question b), but you can have intra-process communication with Interest and Data packets in NFD.<br>
<br>
Regarding ndnSIM, in normal mode, its core works in a single thread, and it?s not that trivial to make your simulation scenario run in multiple-threads.<br>
You can refer to general NS-3 documentation for help.<br>
<br>
To find some information about ?pushing? you can find the section talking about "Command Interests" in NFD developers guide.<br>
