Hi All, I've submitted draft-phelan-dccp-natencap-00.txt to the draft depository. I'm not sure where the notification will go -- it's an individual submission and the automatic submission tool didn't give me a way to tell it to send notification to dccp. I believe it's in the repository now, and it's also available at http://www.phelan-4.com/dccp/draft-phelan-dccp-natencap-00.txt. This draft defines DCCP-NAT, an alternative encapsulation building on a UDP shim layer that will allow DCCP applications to interwork with current NAT devices. The motivation for this is nicely described in Jonathan Rosenberg's new draft-rosenberg-internet-waist-hourglass-00.txt. I didn't know this was coming, but I think it has a point. The approach here is different than the one that SCTP is appearing to take (draft-tuexen-sctp-udp-encaps-01.txt). That seems to insert a couple of bump-in-the-wire encapsulation/decapsulation functions. DCCP-NAT specifies a new native encapsulation. Comments appreciated. Tom P.
