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


	Title		: Network Mobility Support Requirements

The purpose of traditional mobility support is to provide continuous
Internet connectivity to mobile hosts only (host mobility support).
In contrast, network mobility support (NEMO support) deals with
situations where an entire network changes its point of attachment to
the Internet and thus its reachability in the topology. In this
situation, mobility support is to provide continuous Internet
sessions not only to the router connecting the mobile network to the
global Internet, but also to nodes behind the mobile router. This
document tries to identify what constraints limit the implementation
and the deployment of a potentially and ideally good solution, and
what requirements solutions must comply with. Our main aim is to
raise the discussion on the mailing list.

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.
