Hi all, Please find a revision (02) of PCEP Requirements and Extensions for WSON RWA (http://www.ietf.org/internet-drafts/draft-lee-pce-wson-routing-wavelength-0 2.txt). This version has accommodated all the comments from the last meeting at Philadelphia. Please also find a new draft that analyses PCE Routing Architecture Options discussed in the draft-lee-pce-wson-routing-wavelength-02.txt and WSON FRAME. This new draft is entitled "Performance Evaluation of PCE Architectures for Wavelength Switched Optical Networks" (http://www.ietf.org/internet-drafts/draft-bernstein-pce-wson-evaluation-00. txt). Attached is the PDF version of this draft that includes graphical figures that describe some simulation results which are not available for txt version. We'd appreciate your review and comments. See you all in Dublin shortly. Thanks.

Title : PCEP Requirements and Extensions for WSON Routing and Wavelength Assignment Author(s) : Y. Lee, G. Bernstein Filename : draft-lee-pce-wson-routing-wavelength-02.txt Pages : 16 Date : 2008-6-30 This memo provides application-specific requirements and protocol enhancements 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. Different computational architectures for the RWA process are given and the PCEP extensions needed to support these architectures are defined.

Title : Performance Evaluation of PCE Architectures for Wavelength Switched Optical Networks Author(s) : G. Bernstein Filename : draft-bernstein-pce-wson-evaluation-00.txt Pages : 11 Date : 2008-06-30 In this note a number of PCE architectural and computational options are evaluated against a medium sized wavelength switched optical network. The key performance measures of overall and backward blocking are reported under different dynamic traffic scenarios. The corresponding reduction in connection blocking probabilities and computational advantages enabled by these architectural alternatives strongly warrant their inclusion in continuing PCE WSON work.
