Wavelength Assignement Object http://tools.ietf.org/html/draft-lee-pce-wson-rwa-ext-03 And additions.. The format of the Wavelength Assignment (WA) object body is as follows: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Flags | O |M| +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | // Optional TLVs // | | Lee & Casellas Expires April31,2012 [Page 7] Internet-Draft PCEP Extension for WSON RWA October 2011 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Figure 3 WA Object o Flags (32 bits) The following new flags SHOULD be set . M (Mode - 1 bit): M bit is used to indicate the mode of wavelength assignment. When M bit is set to 1, this indicates that the label assigned by the PCE must be explicit. That is, the selected way to convey the allocated wavelength is by means of Explicit Label Control (ELC) [RFC4003] for each hop of a computed LSP. Otherwise, the label assigned by the PCE needs not be explicit (i.e., it can be suggested in the form of label set objects in the corresponding response, to allow distributed WA. In such case, the PCE MUST return a Label_Set object in the response if the path is found. (Ed note: When the distributed WA is applied, some specific wavelength range and/or the maximum number of wavelengths to be returned in the Label Set might be additionally indicated. The optional TLV field will be used for conveying this additional request. The details of this encoding will be provided in a later revision.) . O (Order - 3 bits): O bit is used to indicate the wavelength assignment constraint in regard to the order of wavelength assignment to be returned by the PCE. This case is only applied when M bit is set to "explicit." The following indicators should be defined: 000 - Reserved 001 - Random Assignment 010 - First Fit (FF) in descending Order 011 - First Fit (FF) in ascending Order 100 - Last Fit (LF) in ascending Order 101 - Last Fit (LF) in descending Order 110 - Vendor Specific/Private Lee & Casellas Expires April31,2012 [Page 8] Internet-Draft PCEP Extension for WSON RWA October 2011 111 - Reserved When the Order bit is set for "Vendor Specific/Private", the optional TLV field will be used to indicate specifics of the order algorithm applied by the PCE.
