          RSVP-TE Extensions for Associated Bidirectional LSPs
         draft-ietf-ccamp-mpls-tp-rsvpte-ext-associated-lsp-08

Abstract

   This document describes Resource reSerVation Protocol (RSVP)
   extensions to bind two point-to-point unidirectional Label Switched
   Paths (LSPs) into an associated bidirectional LSP. The association is
   achieved by defining the new Association Types in (Extended)
   ASSOCIATION object. In addition, RSVP extensions allow asymmetric
   upstream and downstream bandwidths for the bidirectional LSP.
