Host Group Extensions for CLNP Multicasting
Status of this Memo

community. This memo does not specify an Internet standard of any
kind. Discussion and suggestions for improvement are requested.

Abstract
This memo documents work performed in the TUBA (TCP/UDP over Bigger
Addresses) working group of IPng area prior to the July 1994 decision
to utilize SIPP-16 as the basis for IPng. The TUBA group worked on
extending the Internet Protocol suite by the use of ISO 8473 (CLNP)
and its related routing protocols. This memo describes multicast
extensions to CLNP and its related routing protocols for Internet
multicast use. Publication of this memo does not imply acceptance by
any IETF Working Group for the ideas expressed within.
This memo provides a specification for multicast extensions to the
CLNP protocol similar to those provided to IP by RFC 1112. These
extensions are intended to provide the mechanisms needed by a host
for multicasting in a CLNP based Internet. This memo covers
addressing extensions to the CLNP addressing structure, extensions to
the CLNP protocol and extensions to the ES-IS protocol. An appendix
discusses the differences between IP multicast and the CLNP multicast
approach provided in this memo.
Acknowledgments
The specification provided here was developed by a number of
individuals in the IETF TUBA working group as well as the ANSI X3S3.3
and ISO SC6 WG2 committees. Key contributions were made by Steve
Deering, Joel Halpern, Dave Katz and Dave Oran.
