How to measure processing delay in ndnSIM node? #75

Closed pengminjiong closed 8 years ago

pengminjiong commented 8 years ago

once a relay node received several same interest packet, process in the relay node(not sure, please check them): 1, look up FIB 2 Keep the same interest packet in PIT 3 send out one interest packet to the publisher 4 receive data from the publisher 5 move data to cache 6 send back to the subscribers .

Is it possible to measure the processing delay(look up FIB , keep the same interest packets) in ndnSIM ? I found simulator virtual time do not have processing delay. really need help

NS-3 is a discrete even simulator. Unless you define a model which simulates the processing time, any actual function invocation takes 0 of simulation time. In other words, it is not easy (if possible at all) simulate processing delays in NS-3 and ndnSIM.
