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:


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:


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

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.
