Technical Summary
This document provides a model of information needed by the routing
and wavelength assignment (RWA) process in wavelength switched
optical networks (WSONs). The purpose of the information described
in this model is to facilitate constrained lightpath computation in
WSONs. This model takes into account compatibility constraints
between WSON signal attributes and network elements but does not
include constraints due to optical impairments. Aspects of this
information that may be of use to other technologies utilizing a
GMPLS control plane are discussed.
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.
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.
