RFC 5467         Asymmetric Bandwidth Bidirectional LSP       March 2009

Abstract

   This document defines a method for the support of GMPLS asymmetric
   bandwidth bidirectional Label Switched Paths (LSPs).  The presented
   approach is applicable to any switching technology and builds on the
   original Resource Reservation Protocol (RSVP) model for the transport
   of traffic-related parameters.  The procedures described in this
   document are experimental.
