This draft is a work item of the Multicast & Anycast Group Membership Working Group of the IETF.
Title : Socket Interface Extensions for Multicast Source

IGMPv3 for IPv4 adds the capability for applications to express
source filters on multicast group memberships, which allows
receiver applications to determine the set of senders (sources)
from which to accept multicast traffic. This capability also
simplifies support of one-to-many type multicast applications. It
is expected that in the near future, the same capability will be
available in IPv6 as well.
This document specifies new socket options and functions to manage
source filters for IP Multicast group memberships. It also
defines the socket structures to provide input and output
arguments to these new APIs. These extensions are designed to
provide access to the source filtering features, while introducing
a minimum of change into the system and providing complete
compatibility for existing multicast applications.

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
