Description of Working Group:


    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.
