[ndnSIM] How to calculate RTT value in ndnSIM

[Klaus Schneider]

Also, if you want the RTT for every single packet, you can look into 
RttMeanDeviation::AckSeq():

> m = Simulator::Now() - i->time; // Elapsed time

Then use this time right there, or store it in a map<seq, Time>.

Best regards,
Klaus
