We plan to use at least half of that time to discuss recent work in the bufferbloat area (on CoDel), but are now also soliciting for other area-wide topics that people may want to discuss in meeting time. Please let Martin and I know if you have a request.

The TSV ADs checked this out and felt that the best path to process it would be AD- sponsoring since there isn't a good WG to fit it into at the moment, and the changes are relatively well constrained. http://tools.ietf.org/html/draft-sandlund-rfc4996bis-02 The authors have nicely described the functional changes in the bis document as: o The SACK option compression in [RFC4996] assumed that multiple SACK blocks within the same option would be in sorted order so that the block starts were LSB-encoded from the end of the previous block. This meant that SACK blocks that are not in sorted order could be impossible to compress in some cases. Therefore, the SACK compression in the formal notation has changed and therefore also the bits-on-the-wire. o The ESP NULL header compression has been deprecated due to interoperability problems with needing to know information from the trailer. The ESP NULL compression was already removed from ROHCv2 [RFC5225] for the same reason and it was considered better to remove it from this profile rather than try to fix the interoperability issue. There are some non-functional changes (e.g. clarifications and FN code corrections) as well, which are also summarized in the document. This is felt to be ready to go forward, and should start an IETF LC soon. If people are interested in this and have comments, please use either the TSVAREA list to provide them, or respond to the IETF LC. -- Wes Eddy MTI Systems
