Abstract

   This memo defines extensions to LMP(rfc4209) for managing Optical
   parameters associated with Wavelength Division Multiplexing (WDM)
   systems or characterized by the Optical Transport Network (OTN) in
   accordance with the Black-Link approach defined in ITU-T
   Recommendation G.698.2[ITU.G698.2].[ITU.G698.2],

1.  Introduction

   This extension is based on
   "draft-galikunze-ccamp-g-698-2-snmp-mib-00" and
   "draft-kunze-g-698-2-management-control-framework-02", for the
   relevant parameters specified in G.698.2 [ITU.G698.2].

2.  Extensions to LMP-WDM Protocol

   This document defines extensions to [RFC4209] to allow the Black Link
   (BL) parameters of G.698.2, as described in the draft
   draft-kunze-g-698-2-management-control-framework-02, to be exchanged
   between a router or optical switch and the optical line system to
   which it is attached.  In particular, this document defines
   additional Data Link sub-objects to be carried in the LinkSummary
   message defined in [RFC4204].  The OXC and OLS systems may be managed
   by different Network management systems and hence may not know the
   capability and status of their peer.  The intent of this draft is to
   enable the OXC and OLS systems to exchange this information.  These
   messages and their usage are defined in subsequent sections of this
   document.

   These are the general parameters as described in [G698.2].  Please
   refer to the "draft-galikunze-ccamp-g-698-2-snmp-mib-00". for more
   details about these parameters.

     The general parameters are
         1. Single-channel application codes -- 32 bytes
         2. Vendor Transceiver Class -- 32 bytes
         When Single-channel application code (which is defined in G.698.2) is
         used in the message, then the vendor transaction class need not be used
         (i.e. all 0) and the optional parameters except nominal central
         frequency need not be used. When vendor transaction class is used in the
         message, then the Single-channel application code need not be used
         (i.e. all 0) and the optional parameters needs to be used.

9.  Security Considerations

   LMP message security uses IPsec, as described in [RFC4204].  This
   document only defines new LMP objects that are carried in existing
   LMP messages, similar to the LMP objects in [RFC:4209].  This
   document does not introduce new security considerations.

10.  IANA Considerations

   LMP [RFC4204] defines the following name spaces and the ways in which
   IANA can make assignments to these namespaces: - LMP Message Type -
   LMP Object Class - LMP Object Class type (C-Type) unique within the
   Object Class - LMP Sub-object Class type (Type) unique within the
   Object Class This memo introduces the following new assignments: LMP
   Sub-Object Class names: under DATA_LINK Class name (as defined in
   [RFC4204]) - BL_General (sub-object Type = TBA) - BL_Applicationcode
   (sub-object Type = TBA) - BL_Ss (sub-object Type = TBA) - BL_SsRs
   (sub-object Type = TBA) - BL_Rs (sub-object Type = TBA) - OLS_Status
