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.
Cheers
Greg B.
