Introduction This extension addresses the use cases described by "draft-kdkgall- ccamp-dwdm-if-mng-ctrl-fwk-00". LMP [RFC4902] provides link property correlation capabilities that can be used between a transceiver device and an Optical Line System (OLS) device. Link property correlation is a procedure by which, intrinsic parameters and capabilities are exchanged between two ends of a link. Link property correlation as defined in RFC3591 allows either end of the link to supervise the received signal and operate within a commonly understood parameter window. Here the term 'link' refers in particular to the attachment link between OXC and OLS (see Figure 1). The relevant interface parameters are in line with "draft-galikunze- ccamp-dwdm-if-snmp-mib-01" and "draft-dharini-ccamp-dwdm-if-yang-00". Hiremagalur, et al.

DWDM line system Figure 1 shows a set of reference points (Rs and Ss), for a single- channel connection between transmitter (Tx) and receiver (Rx) devices. Here the DWDM network elements in between those devices include an Optical Multiplexer (OM) and an Optical Demultiplexer (OD). In addition it may include one or more Optical Amplifiers (OA) and one or more Optical Add-Drop Multiplexers (OADM). +-------------------------------------------------+ Ss | DWDM Network Elements | Rs +--+ | | | \ / | | | +--+ Tx L1--|->| \ +------+ +------+ / |--|-->Rx L1 +---+ | | | | | +------+ | | | | | +--+ +---+ | | | | | | | | | | | | +--+ Tx L2--|->| OM |-->|------|->| OADM |--|------|->| OD |--|-->Rx L2 +---+ | | | | | | | | | | | | +--+ +---+ | | | | | +------+ | | | | | +--+ Tx L3--|->| / | DWDM | | ^ | DWDM | \ |--|-->Rx L3 +---+ | | / | Link +----|--|----+ Link | \ | | +--+ +-----------+ | | +----------+ +--+ +--+ | | Rs v | Ss +-----+ +-----+ |RxLx | |TxLx | +-----+ +-----+ Ss = Sender reference point at the DWDM network element tributary output Rs = Receiver reference point at the DWDM network element tributary input Lx = Lambda x OM = Optical Mux OD = Optical Demux OADM = Optical Add Drop Mux from Fig. 5.1/G.698.2 Figure 1: Linear Single Channel approach Hiremagalur, et al.

Use Cases The use cases are described in draft-kdkgall-ccamp-dwdm-if-mng-ctrl- fwk 4. Extensions to LMP-WDM Protocol This document defines extensions to [RFC4209] to allow a set of characteristic parameters, 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. These messages and their usage are defined in subsequent sections of this document. Hiremagalur, et al.

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 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 ) - OCh_General (sub-object Type = TBA) - OCh_ApplicationIdentifier (sub-object Type = TBA) - OCh_Ss (sub-object Type = TBA) - OCh_Rs (sub-object Type = TBA) 11.
