This document discusses the creation of negative-acknowledgment
(NACK)-oriented reliable multicast (NORM) protocols.  The rationale
for NORM goals and assumptions are presented.  Technical challenges
for NACK-oriented (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 NORM protocol operation.  It is anticipated that
these building blocks will be useful in generating different
instantiations of reliable multicast protocols.

This document is a product of the Reliable Multicast Transport Working
Group of the IETF.
