A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: SCTP Partial Reliability Extension
	Author(s)	: R. Stewart, M. Ramalho
	Filename	: draft-stewart-tsvwg-prsctp-04.txt
	Pages		: 27

This memo describes an extension to the Stream Control Transmission
Protocol (SCTP) RFC2960 [4] that allows an SCTP endpoint to signal to
its peer that it should move the cumulative ack point forward.  When
both sides of an SCTP association support this extension, it can be
used by an SCTP implementation to provide partially reliable data
transmission service to an upper layer protocol.  This memo describes
(1) the protocol extensions, which consist of a new parameter for
INIT and INIT ACK, and a new FORWARD TSN chunk type (2) one example
partially reliable service that can be provided to the upper layer
via this mechanism.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
