	Title		: A Framework for Network-based VPNs
	Author(s)	: M. Suzuki
	Filename	: draft-suzuki-nbvpn-framework-00.txt
	Pages		: 32
	Date		: 13-Jul-00
	
The objective of this draft is to clarify a framework for
standardizing the mechanisms supporting interoperable network-based
virtual private networks (NBVPNs).  These are VPNs using IP
facilities whose operation mechanisms are implemented within a
network (or networks) and outsourced to one or more service
providers.
This draft first describes the assumed services of NBVPNs and
clarifies the logical architecture model and reference model of
NBVPN.  Considering the assumed services, this draft further
clarifies the NBVPN requirements for interfaces and MIBs in the
reference model.  It also surveys and discusses current technologies
supporting NBVPNs such as tunneling, VPN identifier, routing, and
QoS/SLA.  Additionally it will, in future, provide outline of the
interface and MIB specifications and present criteria for achieving
interoperability.

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.
