     Signaling Extensions for Wavelength Switched Optical Networks
                 draft-ietf-ccamp-wson-signaling-07.txt

Abstract

   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
   equipment.

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with
   the provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF), its areas, and its working groups.  Note that
   other groups may also distribute working documents as Internet-
   Drafts.

   Internet-Drafts are draft documents valid for a maximum of six
   months and may be updated, replaced, or obsoleted by other documents
   at any time.  It is inappropriate to use Internet-Drafts as
   reference material or to cite them other than as "work in progress."
