A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Source-Specific Multicast Working Group of the IETF.
Title : Source-Specific Multicast for IP
Author(s) : H. Holbrook, B. Cain
Filename : draft-ietf-ssm-arch-01.txt
Pages : 14
Date : 2002-11-7
IP addresses in the 232/8 (232.0.0.0 to 232.255.255.255) range are
designated as source-specific multicast (SSM) destination addresses and
are reserved for use by source-specific applications and protocols
[IANA-ALLOCATION]. For IP version 6 (IPv6), the address prefix
FF3x::/32 is reserved for Source-Specific Multicast use, where 'x' is
any valid scope identifier [IPV6-UBM]. This document defines the
semantics of source-specific multicast addresses and specifies the
policies governing their use. It defines an extension to the Internet
network service that applies to datagrams sent to SSM addresses and
defines the host and router requirements to support this extension.
A companion document will describe how the Internet Group Management
Protocol Version 3 [IGMPv3] and the Multicast Listener Discovery
Protocol Version 2 [MLDv2] are adapted to support source-specific
multicast.

In the body type:

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.
