Nitin,
I'm not sure I understand, RTT (Round Trip Time) doesn't make sense for RTP streams, as they are unacknowledged and simplex (travel in one direction). Where are you seeing this calculation?

Hi All
I have an issue with the Wireshark for calcuating the RTT values. For few pcaps, I have a higher value of RTT on one side or direction but the lower value of RTT on other side.
I have taken the trace in the middle of the connections and in one direction the RTT calculated by Wireshark is around 40 ms but on what other direction its 1.5 ms.
But i think ideally both the sides should have the same values as its round trip time(like a loop).
The trace is RTP over UDP over a VoIP tool.
Now, when i use some other licensed tool based on libpacp used by Wireshark as well, the values for both the sides is almost same with the same pcap file.
So, i am not sure if Wireshark is calculating the wrong RTT values or the interpreation is differnet by other tools as how to calcuate the RTT vlaues??
Any idea about this??
Regards
Nitin
