[ndnSIM] Using the ComsumerWindow Application

[Spyridon (Spyros) Mastorakis]

Hi Ashiq,

this behavior has to do with the fact that the window application is based on a maximum sequence number for the data to be fetched.

When you do not specifically set the max sequence number or the size of the data to be fetched (this is implicitly converted to a max seq number), then the application assumes max seq num = 0, tries to send out a single Interest (which does not eventually send since the current seq num is equal to the max one) and then stops.

To change this behavior and make the app send data until the end of the simulation, change line 131 of the ndn-consumer-window.cpp to:

m_seqMax = std::numeric_limits<uint32_t>::max();

Hope that this helps,

I did other experiments with the ConsumerCbr application in same scenario setup and that worked fine. What could I possibly be doing wrong?
