[ndnSIM] Re: ConsumerBatches

Hi Akash,

There is no limit for "batches", but the logic implemented inside the ConsumerBatches class may not be exactly what you're expecting.  Actually, if you run your simulation long enough (for the modified version of ndn-simple.cc it took ~900 seconds), it will created all the created Interests (5023 to be exact).

You can check the current logic for scheduling the Interest in apps/ndn-consumer-batches.cc line 86-96.  Basically, the consumer is trying to express only singular Interests, pacing each interest in the batch with the current RTT estimate, to ensure they are not dropped.  In other words, there are no surges of Interests at any given point of time.  Not sure what logic you want the on-off consumer to have, but you can try to create a new consumer, combining ConsumerCbr and ConsumerBatches classes.
