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 “.
Would a change similar to the following suffice?
