This document provides extensions to Generalized Multiprotocol Label Switching (GMPLS) signaling for control of Wavelength Switched Optical Networks (WSONs). Fundamental extensions are given to permit simultaneous bidirectional wavelength assignment, while more advanced extensions are given to support the networks described in [RFC6163], which feature connections requiring configuration of input, output, and general signal processing capabilities at a node along a Label Switched Path (LSP).

      Signaling Extensions for Wavelength Switched Optical Networks


   This document provides extensions to Generalized Multiprotocol Label    Switching (GMPLS) signaling for control of Wavelength Switched    Optical Networks (WSONs).  Such extensions are applicable in WSONs    under a number of conditions including: (a) when optional processing,    such as regeneration, must be configured to occur at specific nodes    along a path, (b) where equipment must be configured to accept an    optical signal with specific attributes, or (c) where equipment must    be configured to output an optical signal with specific attributes.    This document provides mechanisms to support distributed wavelength    assignment with a choice of distributed wavelength assignment    algorithms.
