Generalized MPLS extends MPLS to encompass time-division (e.g. SONET ADMs), wavelength (optical lambdas) and spatial switching (e.g. incoming port or fiber to outgoing port or fiber). This document presents an RSVP-TE specific description of the extensions. A CR-LDP specific description can be found in [GMPLS-LDP]. A generic functional description is presented in [GMPLS-SIG]. @@ -80,24 +85,21 @@ 6 Protection Object ......................................... 17 6.1 Procedures ................................................ 17 7 RSVP Message Formats ...................................... 17 8 Acknowledgments ........................................... 19 9 Security Considerations ................................... 20 10 References ................................................ 20 11 Authors' Addresses ........................................ 21 Changes from previous version: -o Fixed format of notification message.

Introduction Generalized MPLS extends MPLS from supporting packet (PSC) interfaces and switching to include support of three new classes of interfaces and switching: Time-Division Multiplex (TDM), Lambda Switch (LSC) and Fiber-Switch (FSC). A functional description of the extensions to MPLS signaling needed to support the new classes of interfaces and switching is provided in [GMPLS-SIG].
