Requirements for Generalized MPLS (GMPLS) Signaling Usage and Extensions for Automatically Switched Optical Network (ASON)
RFC 4139

Received changes through RFC Editor sync (changed abstract to 'The Generalized Multi-Protocol Label Switching (GMPLS) suite of protocols has been defined to control different switching technologies and different applications. These include support for requesting Time Division Multiplexing (TDM) connections, including Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) and Optical Transport Networks (OTNs).

This document concentrates on the signaling aspects of the GMPLS suite of protocols. It identifies the features to be covered by the GMPLS signaling protocol to support the capabilities of an Automatically Switched Optical Network (ASON). This document provides a problem statement and additional requirements for the GMPLS signaling protocol to support the ASON functionality. This memo provides information for the Internet community.')
