PCE Extensions for WSON

PCEP Requirements for WSON Routing and Wavelength Assignment

Abstract

This memo provides application-specific requirements for the Path Computation Element communication Protocol (PCEP) for the support of Wavelength Switched Optical Networks (WSON). Lightpath provisioning in WSONs requires a routing and wavelength assignment (RWA) process.  From a path computation perspective, wavelength assignment is the process of determining which wavelength can be used on each hop of a path and forms an additional routing constraint to optical light path computation. Requirements related to optical impairments will be addressed in a separate document.
 

Status and Background

This document is a PCE working group document.

 PCEP Requirements for WSON Impairments

Abstract

This memo provides application-specific requirements for the Path Computation Element communication Protocol (PCEP) for the support of Impairments in Wavelength Switched Optical Networks (WSON). From a path computation perspective, optical impairments are additional constraints on the process of determining an optical light path.

Status and Background

This document is currently "individual submission" that contains requirements for PCEP based on the WSON impairment Framework Working Group document at CCAMP.

PCEP Extensions in support of WSON Signal Compatibility Constraints

Abstract

This memo provides the Path Computation Element communication Protocol (PCEP) extensions for the support of signal compatibility constraints in Wavelength Switched Optical Networks (WSON).

Signal compatibility is an essential path computation constraint in path computation of WSON networks where network elements can be limited to processing WSON signals with specific characteristics and attributes

Status and Background

This document is currently "individual submission" that contains signal compatibility requirements for PCEP based on the WSON Framework Working Group document at CCAMP.
