DCCP notes from IETF-77

[Pasi Sarolahti <pasi.sarolahti@xxxxxx>]

Hi,

I wrote up this short summary what happened with DCCP in the last  
meeting (apologies for forgetting to send these earlier). If you find  
something incorrectly said, shout. The full minutes are available as  
part of tsvwg notes at http://www.ietf.org/proceedings/10mar/minutes/tsvwg.txt 
 .

------------

DCCP did not meet in Anaheim, but the only active draft, draft-ietf- 
dccp-udpencap, was discussed in the TSVWG session, along with a  
similar draft for SCTP. There were some feedback about the mechanism,  
regarding the proposal to reuse UDP length field to implement partial  
checksums, and not using the standard DCCP header with UDP  
encapsulation. The message from the room was towards favoring the  
standard use of UDP and DCCP headers instead of the currently  
documented use. A generic mechanism for UDP encapsulation was also  
brought up as a possible alternative for protocol specific variants.  
No conclusions were made whether the IETF should work on a generic  
approach instead of the protocol-specific alternatives, but it was  
noted that we should decide to pick one of the approaches.

The envisioned next steps would be to revise draft-ietf-dccp-udpencap,  
taking the feedback into account, into a shape that it would be ready  
for WG last call. By (or at) the next meeting, based on the revised  
drafts, we should confirm whether we go forward with the protocol  
specific drafts, or whether the IETF wants to pursue a generic approach.
