Expires April 25, 2013 [Page 2] Internet-Draft draft-dharinigert-ccamp-g-698-2-lmp-01 October 2012 1. Introduction This extension is based on "draft-galikunze-ccamp-g-698-2-snmp-mib-01" 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]. 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.

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 Hiremagalur, et al. Expires April 25, 2013 [Page 3] Internet-Draft draft-dharinigert-ccamp-g-698-2-lmp-01 October 2012 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. 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.
