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.
