A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: Mobile IPv6 handoff by Explicit Multicast

Actual Mobile IPv6 handoff involves two types of the network: re-routing
on the wired region of the network and the activation of the air-link on
the wireless region. In this architecture, a possibility of small break
for a session is still large by the signaling overhead between Home
Agent and Mobile Node (MN). We propose a new handoff method using the
Explicit Multicast (xcast) technique for the Small Group Multicast
(SGM). On the wired section, control/user packets are multicasted by
xcast to the Base Stations where MN can access, then packets are passed
to the air-link activated between a BS and the MN.

In the body type:
	"FILE /internet-drafts/draft-ezaki-handoff-xcast-00.txt".
	
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.
