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
