The Transport Area receives occasional proposals for the development and publication of RFCs dealing with transport topics that are not in scope of an existing working group or do not justify the formation of a new working group. TSVWG will serve as the forum for developing such work items in the IETF.
The TSVWG mailing list is an open discussion forum for such work items, when they arise. The working group meets if there are active proposals that require discussion. The working group milestones are updated as needed to reflect the current work items and their associated milestones.
The currently active TSVWG work items mostly fall under the Following topics:
(A) Maintenance of the Stream Control Transmission Protocol (SCTP), which involves bug fixes to the SCTP specifications and their progression along the standards track. This work item also includes a small number of modular extensions to SCTP. In order to maintain stable specifications, additional work on SCTP in TSVWG requires Area Director approval.
(B) Maintenance of the Resource Reservation Protocol (RSVP) which involves bug fixes to RSVP specifications and their progression along the standards track. This work item may also include a small number of extensions to both RSVP and Integrated Services or advisory documents to address specific application scenarios. In order to maintain stable specifications, additional work on RSVP and/or Integrated Services in TSVWG requires Area Director approval.
(C) Maintenance of IP Differentiated Services (DiffServ) mechanisms, which involves mostly advisory documents on the use of DiffServ in specific application scenarios. Other work items related to DiffServ require Area Director approval.
(D) Selected other work items, which are mostly in TSVWG for historic reasons.
Additional work that does not fall under one of the above topics in TSVWG must satisfy four conditions: (1) WG consensus on the suitability and projected quality of the proposed work item. (2) A core group of WG participants with sufficient energy and expertise to advance the work item according to the proposed schedule. (3) Commitment from the WG as a whole to provide sufficient and timely review of the proposed work item. (4) Agreement by the ADs, who, depending on the scope of the proposed work item, may decide that an IESG review is needed first.
