The current DS-TE (Diffserv Traffic Engineering) approach can only be used with a single OA (Ordered Aggregate) per E-LSP or with L-LSP. It cannot be used to carry multiple OAs per E-LSP. This document motivates reasons where it is desirable to carry multiple OAs per E-LSP. In addition, the document proposes RSVP-TE and CR-LDP extensions to facilitate signalling of multiple traffic parameters for a single E-LSP.
