Precedence: list

This eamail contains a brief overview of the WG status. TSVWG covers a 
wide range of transport-related topics, specifying ranging from 
transport protocols and mechanisms, to network-to-transport interactions 
(including Explicit Congestion Notification and Differentiated 
Services). The WG has two sessions scheduled for IETF-119.

Two drafts are with the RFC Ed, in preparation for publication as RFCs:
• draft-ietf-tsvwg-ecn-encap-guidelines
• draft-ietf-tsvwg-rfc6040update-shim

One draft is submitted to our AD after a WGLC (in AD review with issues 
raised and a revised ID expected)
• draft-ietf-tsvwg-sctp-zero-checksum


Authentication Chunks for SCTP: The work to specify Authentication 
Chunks for SCTP is a bis to  RFC 4895. The progress will be reported at 
the meeting.

SCTP and DTLS: A TSVWG Design Team twas formed that will present 
proposed requirements for DTLS over SCTP. The WG is encouraged to read 
the design team slides ahead of Tuesday's TSVWG meeting, where there 
will be an opportunity for WG feedback. The WG then plans to determine 
which proposals will be used for the basis for a protocol specification. 
Note: There is a proposal for related work being considered by the TLS 
working group.

MP-DCCP: This draft recently completed WGLC review with support to 
publish. The ID is currently with the WG Chairs. This drafts targets PS. 
Offers to provide a technical review of this sepc will be appreciated.

UDP Options: There will be a short summary of the latest revisions to 
the protocol draft, which includes proposals to resolve all current 
issues. The related work on DPLPMTUD is also awaiting completion of this 
spec. The WG will seek WGLC review comments after the IETF-119 TSVWG 
meeting.

NQB PHB: The latest draft includes proposals to resolve all current 
issues. This is thought by the Editor to be ready to proceed to WGLC 
after the IETF-119 TSVWG meeting.

2024.
