Generalized MPLS - an overview

Abstract

CMPLS, being developed by IETF and OIF, has been proposed to address traflc engineering to n variety of nenuoi-king technology, and tu sene in R variety of network signaling layers. exrending capabilities beyond those networks that are only packet-based. GMPLS is an extension of MPLS rind it provides a control plane for devices that swirch in rime, packet, wavelength, and fiber doiliains. This coilinion control pluiie promises to sirnpliJy network operatiori and mariagenient by automating end-to-erid provisioning of coiinections, nianaging network resources, and providing QuS. One of the main architecture enhancements proposed by GMPLS is the cornplete separation of the control and duta planes, allowing high performance, iiitellipn networking ujliile sbiiplifiing networks by combining transport and rmrltiservice switching into a single layered rietwork.
