	Title		: A Two-Level Architecture for Internet Signaling

This memo defines an architectural framework for a wide variety of
Internet signaling protocols.  This framework has a two-level
organization: a common lower layer 'transport' protocol together with
a suite of upper-level signaling protocols.  The common lower level
protocol CSTP (Common Signaling Transport Protocol) provides a
transport-like service that may include reliable delivery and soft
state management.  The upper layer protocols, which implement
algorithms and data structures specific to particular signaling
applications, are generically called ULSPs (Upper-layer Signaling
Protocols).  This memo motivates the two-level design and describes
the service model, API, and operation of the lower level CSTP.

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.
