Generalized Multi-Protocol Label Switching Signaling Constraint-based Routed Label Distribution Protocol Extensions
RFC 3472, “Generalized Multi-Protocol Label Switching Signaling Constraint-based Routed Label Distribution Protocol Extensions”, is a Proposed Standard document published in February 2003 by P. Ashwood-Smith, L. Berger. It has since been updated by RFC 3468, RFC 4201. The canonical text is published by the RFC Editor.
Abstract
This document describes extensions to Multi-Protocol Label Switching (MPLS) Constraint-based Routed Label Distribution Protocol (CR-LDP) signaling required to support Generalized MPLS. Generalized MPLS extends the MPLS control plane to encompass time-division (e.g., Synchronous Optical Network and Synchronous Digital Hierarchy, SONET/SDH), 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. A generic functional description can be found in separate documents. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
