The Datagram Congestion Control Protocol (DCCP) is holding a protocol design review at the Vienna IETF. DCCP is a new transport protocol offering congestion control to (largely multimedia) flows which do not require the reliability of TCP. The charter page is at [1]. More information on the motivation for the working group can be found at [2].

This working group is following an agressive schedule of about 18 months, hoping to publish the spec this November. The three specification documents

draft-ietf-dccp-spec draft-ietf-dccp-ccid2 draft-ietf-dccp-ccid3

are fairly stable and we are nearing completion of an expert review of the documents. (There will be a revision of the drafts before the IETF to incorporate some of the expert reviewer comments. Links to current versions can always be found on the dccp charter page.)

We are hoping that, by holding a design review at this time, we will surface issues which may reveal themselves to the larger IETF community. Interested folks -- particularly from potential user communities -- are invited to attend.
