Hi All, I've submitted draft-ietf-dccp-udpencap-00 to the I-D editor. While we're waiting for it to arrive in the archive, it can be viewed at http://www.phelan-4.com/dccp/draft-ietf-dccp-udpencap-00.txt. You can see a diff with the previous (individual) version at http://tools.ietf.org//rfcdiff?url1=http://www.phelan-4.com/dccp/draft-i etf-dccp-udpencap-00.txt&url2=http://www.ietf.org/id/draft-phelan-dccp-n atencap-03.txt.
This version incorporates changes that were discussed on the mailing list in December or so last year. Important changes are: o Partial checksum -- this was completely modified to use a UDP-Lite type operation. For DCCP-NAT, the UDP Length field is redefined to mean the extent of the packet that is covered by the UDP checksum. This, while still a kludge, is cleaner than the previous mechanism, and provides protection for the UDP header that the previous mechanism didn't. o SDP simplification -- I mostly followed Colin's suggestions for simplifying the SDP, but not completely. Colin, please check this out. o ECN -- there is a new section on ECN support in reaction to Gorry's comments in this area. Gorry, please check this out. o PMTUD -- there is a new section on PMTUD. Basically it just says do what RFC4340 says to do. Tom P.
