The IESG has received a request from the Transport Area Working Group WG (tsvwg) to consider the following document: - 'Stream Schedulers and User Message Interleaving for the Stream Control Transmission Protocol' <draft-ietf-tsvwg-sctp-ndata-12.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-08-25. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Stream Control Transmission Protocol (SCTP) is a message oriented transport protocol supporting arbitrarily large user messages. This document adds a new chunk to SCTP for carrying payload data. This allows a sender to interleave different user messages that would otherwise result in head of line blocking at the sender. The interleaving of user messages is required for WebRTC Datachannels. Whenever an SCTP sender is allowed to send user data, it may choose from multiple outgoing SCTP streams. Multiple ways for performing this selection, called stream schedulers, are defined. A stream scheduler can choose to either implement, or not implement, user message interleaving. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-sctp-ndata/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-sctp-ndata/ballot/ No IPR declarations have been submitted directly on this I-D.
