Diffserv has been deployed in many networks; it provides differentiated traffic forwarding based on the Diffserv Codepoint (DSCP) field, which is part of the IP header [RFC2474]. This document defines a set of common Diffserv classes (Per-Hop Behaviors (PHBs)) and codepoints for use at interconnection points to which and from which locally used classes and codepoints should be mapped.

              Diffserv-Interconnection Classes and Practice


   This document defines a limited common set of Diffserv Per-Hop    Behaviors (PHBs) and Diffserv Codepoints (DSCPs) to be applied at    (inter)connections of two separately administered and operated    networks, and it explains how this approach can simplify network    configuration and operation.  Many network providers operate    Multiprotocol Label Switching (MPLS) using Treatment Aggregates for    traffic marked with different Diffserv Per-Hop Behaviors and use MPLS    for interconnection with other networks.  This document offers a    simple interconnection approach that may simplify operation of    Diffserv for network interconnection among providers that use MPLS    and apply the Short Pipe Model.  While motivated by the requirements    of MPLS network operators that use Short Pipe Model tunnels, this    document is applicable to other networks, both MPLS and non-MPLS.
