Hi, The revision added a couple of new requirements on Wavelength Policy area, both of which was raised by Oscar.
In Section 2.1.5. we have added these new requirements: - The PCReq Message SHOULD be able to request, when requesting a 1+1 connection (e.g. link disjoint paths), that both paths use the same wavelength. Note that this is extremely useful in the case of protection with single transponder. Now, there is no way to specify such constraint. - The PCReq Message SHOULD be able to request, when performing 3R, that wavelength may change or not. Oscar was also added to a new contributor of this draft. Please send your comment if any to the mailing list on these changes.

Title : PCEP Requirements for WSON Routing and Wavelength Assignment Author(s) : Young Lee Greg Bernstein Jonas Martensson Tomonori Takeda Takehiro Tsuritani Oscar Gonzalez de Dios Filename : draft-ietf-pce-wson-routing-wavelength-06.txt Pages : 13 Date : 2011-10-30 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 Optical impairments will be addressed in a separate document.
