[ndnSIM] Find rate of interests in a face

[Spyridon (Spyros) Mastorakis]

Hello,

for the PIT table size you can use the size method of the PIT class:

http://ndnsim.net/2.0/doxygen/classnfd_1_1Pit.html#abfb7bf627d26f0b23e7e9de2ca16965f

For the interest rate you will need to modify the ndn-l3-rate-tracer files:

http://ndnsim.net/2.0/doxygen/ndn-l3-rate-tracer_8cpp.html

To get the real time you can use the method now of either the steady_clock or the system_clock class of ndn-cxx. Personally, I would suggest to use the steady_clock class, because it represents a monotonic clock:

http://named-data.net/doc/ndn-cxx/current/doxygen/d3/d44/classndn_1_1time_1_1system__clock.html

For this, i need to find the rate of incoming interest through each face of the router, do some calculations and decide if to forward the packet or not. For the calculations, i need the PIT table size also. I have heard about tracers. But i need to know the interest rate in real time. I would like to know which file i need to modify to implement my project and also the functions to find the interest rate and the PIT table size.
