Berger, et al. Experimental [Page 1] 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. Table of Contents 1. Introduction ....................................................2 1.1.

Introduction GMPLS [RFC3473] introduced explicit support for bidirectional Label Switched Paths (LSPs). The defined support matched the switching technologies covered by GMPLS, notably Time Division MultiplexingShow full document text
