	Title		: Explicit Multicast (Xcast) Basic Specification

Multicast has become increasingly important with the emergence of
network-based applications such as IP telephony and video
conferencing. The Internet community has done a significant amount of
work on IP multicast over the last decade [1075, 2201, 2236, DEER,
DEE2, FARI, HOLB, MBONE, PERL].
However, while today's multicast schemes are scalable in the sense
that they can support very large multicast groups, there are
scalability issues when a network needs to support a very large
number of distinct multicast groups.

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.
