Hi Greg, this is a timely topic to be tackled for both the PCE and GMPLS WGs, and well worth supporting. I would like to highlight that the renewed interest in this work by carriers is sparked by the fact that there is new optical equipment moving into the network, both in the core as well as in the metro/aggregation area which needs management and configuration. There is no intention to implement fast optical switching at large scale, except during failure recovery and for planned maintenance etc which would affect the IGP stability. Dimitri's remark during the GMPLS WG meeting showed me that it might be necessary to emphasize that position.
Regards, Michael -----Original Message----- From: Greg Bernstein [mailto:[EMAIL PROTECTED] Hi CCAMPer's and PCEr's, we have just published a new draft on the "Applicability of GMPLS and PCE to Wavelength Switched Optical Networks" http://www.ietf.org/internet-drafts/draft-bernstein-ccamp-wavelength-swi tched-00.txt . This draft looks at optical networks that include tunable lasers and ROADM (reconfigurable optical add/drop multiplexers) with no or limited wavelength conversion capability (these components are defined in the draft). These limitations lead to the RWA (routing and wavelength assignment) problem which is a bit more demanding in terms of input information and computation than other constrained path computation problems. In the draft we look at the implications for GMPLS signaling, GMPLS routing, and PCE protocols and suggest some potential extensions to better accommodate this application. We'd appreciate feedback/collaboration on (a) overall interest in this application, (b) requirements discussions, and (c) solution/extension discussions.
