Internet-Draft draft-dharinigert-ccamp-g-698-2-lmp-00 July 2012
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].

OXC : is an entity that contains transponders
OLS : generic optical system, it can be -
Optical mux , Optical demux, Optical Add Drop Mux, et
OLS to OLS : represents the black-Link itself
Rs/Ss : inbetween the OXC and the OLS
Figure 1: Extended LMP Model
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.

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
