RFC 3946 GMPLS Extensions for SONET/SDH Control October 2004

1. Introduction

As described in [RFC3945], Generalized MPLS (GMPLS) extends MPLS from supporting packet (Packet Switching Capable - PSC) interfaces and switching to include support of four new classes of interfaces and switching: Layer-2 Switch Capable (L2SC), Time-Division Multiplex (TDM), Lambda Switch Capable (LSC) and Fiber-Switch Capable (FSC). A functional description of the extensions to MPLS signaling needed to support the new classes of interfaces and switching is provided in [RFC3471]. [RFC3473] describes RSVP-TE specific formats and mechanisms needed to support all five classes of interfaces, and CR- LDP extensions can be found in [RFC3472]. This document presents details that are specific to Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH). Per [RFC3471], SONET/SDH specific...
