This document discusses the creation of reliable multicast protocols
that utilize 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.  This document obsoletes RFC 3941.  [STANDARDS TRACK]
