In the core of a high capacity network, service differentiation may
still be needed to support applications' utilization of the network.
Applications with similar traffic characteristics and performance
requirements are mapped into diffserv service classes based on end-
to-end behavior requirements of the applications.  However, some
network segments may be configured in such a way that a single
forwarding treatment may satisfy the traffic characteristics and
performance requirements of two or more service classes.  In these
cases, it may be desirable to aggregate two or more diffserv service
classes into a single forwarding treatment.  This document provides
guidelines for the aggregation of diffserv service classes into
forwarding treatments.

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
