[ndnSIM] Inconsistent number of sent packets

Hi huyao,

Did you specify any randomization for inter-interest gap using Randomize parameter (uniform, exponential)?  Though, by default there is no randomization.

Btw. Do all your interest are getting satisfied from the first attempt?  If not, the difference can come from the interest retransmission, since those that needs to be retransmitted are sharing the same "cbr" constraints as new interests.

For example, I set the Interest frequency as 10 (packets per second) for 20 seconds, the result is the number of sent packets is 200 which is the same as theoretic value. But if I set the Interest frequency as 100 for 20 seconds, the simulation result is the number of sent packets is 1805 which is less than the theoretic value 2000. What is the possible reason for this phenomenon? (No packets are sent from other faces)
