I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The draft specifies an encoding scheme for information on a Wavelength Switched Optical Network (WSON). Specifically, information that is used for Routing and Wavelength Assignment (RWA). The security considerations section does exist and discloses that the draft does not impose any security considerations in itself, but does admit that documents that reference this draft would have considerations for privacy, spoofing, and tampering of any associated data. I agree with this assertion. General comments: None. Editorial comments: Usually the Abstract is the first section in the draft. The abbreviations should have the expanded word with the corresponding capital letter. GMPLS is not initially expanded in the Abstract section. s/RB identifier./RB identifiers./ Shawn. --
