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 as indicated by
Diffserv Service Classes . 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
