Technical Summary PR-SCTP provides an enhancement to the Stream Control Transmission Protocol (SCTP) that allows an SCTP endpoint to signal to its peer that it should mov the cumulative ack point forward. This allows SCTP to provides its users (upper layer protocols) with a partially reliable transport service. By informing a peer that it should no longer expect to receive one or more DATA chunks, SCTP endpoints can enforce their own rules governing retransmission of data. One potential application of this, which is described in the document, is a "timed reliability" service that specifies a maximum duration of time for which retransmission should be attempted. Working Group Summary The TSVWG working group supported the advancement of this document, and substantial review was performed by participants in the WG. Protocol Quality This document was reviewed for the IESG by Jon Peterson.
