Wireshark-users: [Wireshark-users] RTCP: Calculate round trip delay

Date: Mon, 05 Mar 2007 13:36:02 +0530
Hi all!

I am working on RTCP protocol. I would like to know how to calculate the round-trip-delay for an SSRC.
I know that it can be calculated using the formula

Round trip delay = Arrival time- Last Sender Report Timestamp - Delay since Last Sender Report Timestamp

But I guess the units of Arrival time and the LSR (and DLSR) are different. I use the arrival time as given by Wireshark. I get some weird answers when I subtract the LSR and DLSR from the arrival time.

Can anybody tell me how to go about the problem?

Thanks in advance.
