The IESG has approved the following document: - 'Routing and Wavelength Assignment Information Encoding for Wavelength Switched Optical Networks' (draft-ietf-ccamp-rwa-wson-encode-28.txt) as Proposed Standard This document is the product of the Common Control and Measurement Plane Working Group. The IESG contact persons are Alia Atlas and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ccamp-rwa-wson-encode/ Technical Summary A wavelength switched optical network (WSON) requires that certain key information fields are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON. Part of the WSON information model contains aspects that may be of general applicability to other technologies, while other parts are specific to WSONs. This document provides efficient, protocol-agnostic encodings for the WSON-specific information fields. It is intended that protocol- specific documents will reference this memo to describe how information is carried for specific uses. Such encodings can be used to extend GMPLS signaling and routing protocols. In addition these encodings could be used by other mechanisms to convey this same information to a path computation element (PCE). Working Group Summary This topic been discussed in the WG for a very long time, perhaps 6 years. Support for the work has been tepid, but there are multiple sets of contributors who would like to see the work result in proposed standards. A late discussion about the inclusion of vendor-specific information went back to the WG list and resulted in the removal of such TLVs until the ITU-T has completed its work in this area. Document Quality This document provides background and an approach to extending exiting RFCs for which there are implementations, but does not itself define any protocol mechanisms. The existing RFCs include RFC3471, RFC3473, RFC4202, RFC4203. This work is based on RFC6163. Personnel Lou Berger is the Document Shepherd Adrian Farrel is the Responsible Area Director
