Technical Summary
This memo provides extensions to Generalized Multi-Protocol Label
Switching (GMPLS) signaling for control of Wavelength Switched
Optical Networks (WSON). Such extensions are applicable in WSONs
under a number of conditions including: (a) when optional
processing, such as regeneration, must be configured to occur at
specific nodes along a path, (b) where equipment must be configured
to accept an optical signal with specific attributes, or (c) where
equipment must be configured to output an optical signal with
specific attributes. This document provides mechanisms to
support distributed wavelength assignment with choice in distributed
wavelength assignment algorithms.
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
The base GMPLS protocol has been implemented. The extensions defined in
this document are compatible with earlier implementations. Multiple
implementors have stated their intent to implement, or have stated that
they have already implemented, the mechanisms defined in this document.
Personnel
Lou Berger is the Document Shepherd
Deborah Brungard is the Responsible Area Director
RFC Editor Note
Please change Section 5 Security Considerations, second sentence:
OLD
As such, this
document introduces no new security considerations to the existing
GMPLS signaling protocols.
NEW
The specific additional information (optical resource and wavelength selection
properties) is not viewed as substantively changing or adding to the security
considerations of the existing GMPLS signaling protocol mechanisms.
