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. In addition this memo provides mechanisms to
support distributed wavelength assignment with choice in distributed
wavelength assignment algorithms. These extensions build on previous
work for the control of lambda and G.709 based networks. This
document updates [RFC6205] as make it applicable to WSON-LSC capable

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.

The Document Shepherd has reviewed the document as it has progressed
through the CCAMP WG, including as part of an extended WG last calls.
The Shepherd believes this document is ready for publication. This
document is part of a set of documents on WSON and final publication --
and at the AD's discretion, IETF LC -- should occur as a set.
The documents set includes:
> (4) Does the document Shepherd have any concerns about the depth or
> breadth of the reviews that have been performed?
> (5) Do portions of the document need review from a particular or from
> broader perspective, e.g., security, operational complexity, AAA, DNS,
> DHCP, XML, or internationalization? If so, describe the review that
> took place.
As part of the 2nd WG LC, both the OSPF WGs chairs were consulted, and
one provided comments.
> (6) Describe any specific concerns or issues that the Document Shepherd
> has with this document that the Responsible Area Director and/or the
> IESG should be aware of? For example, perhaps he or she is uncomfortable
> with certain parts of the document, or has concerns whether there really
> is a need for it. In any event, if the WG has discussed those issues and
> has indicated that it still wishes to advance the document, detail those
> concerns here.
No specific concerns.
> (7) Has each author confirmed that any and all appropriate IPR
> disclosures required for full conformance with the provisions of BCP 78
> and BCP 79 have already been filed. If not, explain why.
Yes, via messages to/on the CCAMP WG list.
> (8) Has an IPR disclosure been filed that references this document?
> If so, summarize any WG discussion and conclusion regarding the IPR
No IPR has been disclosed for this document.
> (9) How solid is the WG consensus behind this document? Does it
> represent the strong concurrence of a few individuals, with others
> being silent, or does the WG as a whole understand and agree with it?
Good among interested parties. No objections from others.
> (10) Has anyone threatened an appeal or otherwise indicated extreme

Not to my knowledge.

The document passes tools idnits with 1 warning.

Note that this document uses mechanisms defined in
draft-ietf-ccamp-lsp-attribute-ro which the WG expects to progress/LC
shortly. Given the size of the WSON document set, we expect this
document will be ready for publication at the roughly the same time.

The IANA section was fully reviewed by the document shepherd. Three new
allocations are requested in this document.
Two registries are created, both with Standards Action and Specification
Required policies as defined in [RFC5226].
> (18) List any new IANA registries that require Expert Review for future

> language, such as XML code, BNF rules, MIB definitions, etc.
This document contains RBNF as defined in RFC5511. There are no automated
tools for the validation of such, but RBNF was reviewed and discussed as
part of last call.
