	Title		: Provider Architecture for Differentiated Services

   This document describes the Provider Architecture for Differentiated
   Services and Traffic Engineering (PASTE) for Internet Service
   Providers (ISPs).  Providing differentiated services in ISPs is a
   challenge because the scaling problems presented by the sheer number
   of flows present in large ISPs makes the cost of maintaining per-flow
   state unacceptable.  Coupled with this, large ISPs need the ability
   to perform traffic engineering by directing aggregated flows of
   traffic along specific paths.
 
   PASTE addresses these issues by using Multiprotocol Label Switching
   (MPLS) [1] and the Resource Reservation Protocol (RSVP) [2] to create
   a scalable traffic management architecture that supports
   differentiated services.  This document assumes that the reader has
   at least some familiarity with both of these technologies.

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.

implementation to automatically retrieve the ASCII version of the
