The IESG has approved the following document: - 'Stream Control Transmission Protocol (SCTP) Stream Reconfiguration' (draft-ietf-tsvwg-sctp-strrst-13.txt) as a Proposed Standard This document is the product of the Transport Area Working Group. The IESG contact persons are Wesley Eddy and David Harrington. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tsvwg-sctp-strrst/ Technical Summary Many applications that use SCTP want the ability to "reset" a stream. The intention of resetting a stream is to set the numbering sequence of the stream back to 'zero' with a corresponding notification to the upper layer that this has been performed. The applications that want this feature want it so that they can "re-use" streams for different purposes but still utilize the stream sequence number so that the application can track the message flows. Thus, without this feature, a new use of an old stream would result in message numbers greater than expected unless there is a protocol mechanism to "reset the streams back to zero". This document also includes methods for resetting the transport sequence numbers, adding additional streams and resetting all stream sequence numbers. Working Group Summary Understanding that 'strong' consensus is nearly impossible in an open area WG such as TSVWG, with 5-6 sub-groups within this WG divided along technology focuses -- there is unwavering consensus in the WG amongst interested parties to publish this document. It has been reviewed by several people in the WG last call. Document Quality Only part of this document has been implemented to date in FreeBSD. Other implementations are progressing, but their status is unknown at this time. There is interest in this document from other groups that will use the features it provides. The IETF IPFIX working group is one example. Personnel James Polk <jmpolk@cisco.com> is the Document Shepherd, and Wesley Eddy <wes@mti-systems.com> is the responsible AD. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
