Hi all, I would like to know the ways to calculate RTT on a RTP receiver
(client) that does not send back packets to sender (Server) in RTP session.
Since, receiver does not send back any packets to the sender, the sender should
not include receiver report blocks in the SR RTCP packets and hence
receiver does not know the "delay on the sender since it
received last RR" and can not calculate RTT using the scheme
mentioned in section "6.4.1 SR: Sender Report RTCP Packet". How does a receiver that does not send back any packets back to
the sender calculate RTT? I will be obliged if some one could help me on the
same. I
would like to add one more point. RFC
3550 also mentions that NTP can be used to calculate RTT, but I think it can
be used to calculate only one side delay and multiplying it by 2 to
get RTT may not be a great idea as the delay may be
different. Regards, Vikal. |
