	Title		: Explicit Multicast (Xcast) Concepts and Options

While traditional IP multicast schemes [1112] are scalable for very
   large multicast groups, they have scalability issues with a very
   large number of distinct multicast groups.  This document describes
   Xcast (Explicit Multi-unicast (Xcast)), a new multicast scheme with
   complementary scaling properties: Xcast supports a very large number
   of small multicast sessions.  Xcast achieves this by explicitly
   encoding the list of destinations in the data packets, instead of
   using a multicast group address.

   This document discusses Xcast concepts and options in several areas;
   it does not provide a complete technical specification.

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
