[ndnSIM] How to manually set name of Interest and Data

[Alex Afanasyev]

Hi Kengo,

There are a few ways of achieving this.  The simplest one is to modify the existing Produce application to remove the assumption that all requested data exist and only reply the Interests of your choice.

A little bit more complex, but future proof, is to write a second producer applications the implements your behavior.  We will be really happy to merge this code into the ndnSIM.

In ndn-simple.cpp using the Helper "consumerHelper.SetPrefix("/prefix")," it would automatically add 0, 1, ... to the end of /prefix/. Then using the "producerHelper.SetPrefix("/prefix")" the Producer would return the matching Data packet, assuming it exist.
