I've just submitted draft-ietf-dccp-serv-codes-05.txt. This revision incorporates feedback around the last DCCP WG meeting via the list and meeting, and recent comments from Colin on the interim version:
Tom Phelan suggested clarification was needed for the usage of well- known ports in section 1, and various other clarifications. Eddie Kohler suggested reworking the midbox section. Eddie noted the hash function included the highest numbered port, which is not accessible on all OS. There was also discussion about the proper server port range to be used with this method. After previous concerns that using registered ports could have some (unknown) side effect, use was recommended in the dynamic range. Text was added to this section. Discussions at IETF-71 lead to the idea to removing the IANA guidance on maintaining the registries to a new document that defines the policy across the set of transport registries. Eddie noted that port-reuse is likely to be more common with DCCP (security considerations). Lars noted that rate-limiting benchmarking tools may be somewhat undesirable, and this related to services for testing. The text recommending an update to the IANA procedures for ports and service codes has been moved to a TSV WG draft. The draft is available at the IETF I-D archive: http://www.ietf.org/internet-drafts/draft-ietf-dccp-serv-codes-05.txt Comments are welcome.
