Hi, I looked at section 10 and have some comments 1.
If RTP/RTCP multiplexing is used,
there is no need for any specific operation from the RR side. The RR sends the
RAMS-R message to the RS from the port it wants to receive the RAMS-I and RTP
payload. The RS just sends the information to the port from which it received
the RAMS-R and not to the one in the SDP 2.
In the case where there is no
RTP/RTCP multiplexing, the RAMS-R RTCP message will go to the RS and the RAMS-I
will go to the port on the RR from where the RAMS-R was received. For the RTP,
the RR does not know if it has a NAT on the way to the RS and should try to get
a routable address (using STUN for example) and providing the port to the RS (
we still need to agree on how to do it) 3.
If the above two points are
correct than the RR receive port in the SDP is not really useful Roni Even |
