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 a CR-LDP specific description of the extensions. An RSVP-TE specific description can be found in [GMPLS- RSVP]. A generic functional description is presented in [GMPLS-SIG]. @@ -70,22 +74,21 @@ 5.1 Procedures ................................................ 10 6 Protection TLV ............................................ 11 6.1 Procedures ................................................ 12 7 Acknowledgments ........................................... 12 8 Security Considerations ................................... 12 9 References ................................................ 12 10 Authors' Addresses ........................................ 13 Changes from previous version: -o Removed SONET/SDH specifics. -o Added Acceptable Label Set +o Fixed Label Set format 1. 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].
