1. Introduction
This extension is based on "draft-galikunze-ccamp-opt-imp-snmp-
mib-00" and "draft-kunze-g-698-2-management-control-framework-02",
for the relevant optical parameters mainly (but not restrictriced to)
described in recommendations like ITU-T G.698.2 [ITU.G698.2] and
G.694.1 [ITU.G694.1]. This document further extend the draft-
dharinigert-ccamp-g-698-2-lmp-03. The LMP Model from RFC4902 is
extended to provide link property correlation between a client and an
OLS device. By using LMP, the capabilities of either end of this
link are exchanged where the term 'link' refers to the attachment
link between OXC and OLS (see Figure 1). By performing link property
correlation, both ends of the link can agree on a common parameter
window that can be supported and supervised by each device. The
actual selection of a specific parameter value whithin the parameter
window is outside the scope of LMP. In GMPLS the parameter selection

(e.g. wavelength) is performed by RSVP-TE and Wavelength routing by
IGP. This document does not include the ITU-T G.698.2 "application-
code" and few other parameters described in the draft draft-

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] and [RFC6205]. 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.
The following new messages are defined for the WDM extension for
ITU-T G.698.2 [ITU.G698.2]/ITU-T G.698.1 [ITU.G698.1]/
ITU-T G.959.1 [ITU.G959.1]

These are the general parameters as described in [G698.2]. Please
refer to the "draft-galikunze-ccamp-g-698-2-snmp-mib-02". for more
details about these parameters.
The general parameters are

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

Sub-Object Class names: under DATA_LINK Class name (as defined in
