[Rmt] I-D ACTION:draft-ietf-rmt-bb-norm-revised-01.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Reliable Multicast Transport Working Group of the IETF.

	Title		: Multicast Negative-Acknowledgment (NACK) Building Blocks
	Author(s)	: B. Adamson, et al.

This document discusses the creation of reliable multicast protocols
utilizing negative-acknowledgment (NACK) feedback.  The rationale for
protocol design goals and assumptions are presented.  Technical   challenges for NACK-based (and in some cases general) reliable
multicast protocol operation are identified.  These goals and
challenges are resolved into a set of functional "building blocks"
that address different aspects of reliable multicast protocol
operation.  It is anticipated that these building blocks will be
useful in generating different instantiations of reliable multicast
protocols.

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.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
