A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCEP Requirements for WSON Routing and Wavelength Assignment Authors : Young Lee Greg Bernstein Jonas Martensson Tomonori Takeda Takehiro Tsuritani Oscar Gonzalez de Dios Filename : draft-ietf-pce-wson-routing-wavelength-14.txt Pages : 13 Date : 2014-10-13 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 for PCEP extensions in support of optical impairments will be addressed in a separate document.
