In 2000, XCAST (Explicit Multi-Unicast) was first proposed as a
protocol intended for small group multicasting. It combined three
similar datagram simulcasting protocols that were submitted as
earlier Internet Drafts by a number of different research groups.
After that, researchers in those groups worked together to further
develop, experiment and conduct standardization in IETF as well as in
the open source community. This resulted in several implementations
of protocol stacks, systems of multi-party video conference and group
management, and mechanisms for harmonizing XCAST with ASM and SSM. In
addition, an XCAST backbone for various experiments has been launched
to operate inter-continentally.
One of the main purposes of this document is to summarize the efforts
undertaken by XCAST community as "best current practices" that would
then be formally introduced to the IETF/IRTF community. In addition,
we raise an issue concerning IANA resource allocation, which prevents
us from widely expanding our experimental networks as well as
distributing our software. Finally, we request IESG and other experts
to check the validity of our proposed protocol and make any
suggestions about how IANA can assign appropriate resources
accordingly.

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.
