Abstract

   This document defines a flexible solution for support of
   Differentiated Services (Diff-Serv) over Multi-Protocol Label
   Switching (MPLS) networks.

   This solution allows the MPLS network administrator to select how
   Diff-Serv Behavior Aggregates (BAs) are mapped onto Label Switched
   Paths (LSPs) so that he/she can best match the Diff-Serv, Traffic
   Engineering and protection objectives within his/her particular
   network.  For instance, this solution allows the network
   administrator to decide whether different sets of BAs are to be
   mapped onto the same LSP or mapped onto separate LSPs.
