The Internet Group Management Protocol (IGMPv3) for IPv4 and the
Multicast Listener Discovery (MLDv2) for IPv6 add 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.

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 application program interfaces (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.

This document is a product of the Multicast & Anycast Group Membership
Working Group of the IETF.
