[ndnSIM] N consumers M distinct producers

I'm trying to setup a scenario where there are M distinct producers 1...M.
Each producer is responsible for a certain prefix /producer1 ... /producerM.

There are also N consumers which generate requests for interests ranging
from /producer1 to /producerM followiing a zipf distribution.

I modified the zipfmandelbrotconsumer by changing the following line

  Ptr<Name> nameWithSequence = Create<Name>
  //nameWithSequence->appendSeqNum (seq);


I then installed a consumerapp and producerapp on each node accordingly.


The simulation runs for a very brief amount of time before receiving an error.

Is there any naming convention assumed in the routing such as
/producer/1 /producer/2 instead of being able to route to /producer1
/producer2 ?
