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.
