Hi Greg. I'm really interested in this topic, but I think I've missed some points when reading your ID.
For instance, I don't get why you consider the signal modulation format. I don't believe a single-vendor environment would require a negociation on modulation for a specific bandwidth, and I don't think modulation information would be enough for 2 different implementations to interwork on (analog) optical line. Anyway, this work is a good start to highlight GMPLS and PCE lack to handle the different kinds of optical networks. Regards, Julien -----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-switched-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.
