Dear Colin, As discussed during the meeting, I would like to remind you that the following paragraph from Section 4.1 (http://www.ietf.org/internet-drafts/draft-ietf-dccp-rtp-04.txt) requires a sentence or two stating that the probing mechanism described is under the assumption that the underlying DCCP mechanism does not do any probing. If the underlying CCID does probing (for eg Faster Restart), then please state what the sender should do or could do. “A DCCP connection is opened when an end system joins an RTP session, and it remains open for the duration of the session. To ensure NAT bindings are kept open, an end system SHOULD send a zero length DCCP- Data packet once every 15 seconds during periods when it has no other data to send. This removes the need for RTP no-op packets [18], and
similar application level keep-alives,
when using RTP over DCCP “. Regards Arjuna ------------------------------- Dr.Arjuna Sathiaseelan Electronics Research Group Email: arjuna@xxxxxxxxxxxxxx Web: www.erg.abdn.ac.uk/users/arjuna Phone : +44-1224-272780 |
