6.4. LMP
LMP is a protocol being standardized by the IETF. Its functionality includes:
Link connectivity verification: Supports the discovery of topological links between adjacent OXCs or PXCs.
Link parameter correlation: Supports the exchange of link parameters between adjacent NEs.
Control channel management: Allows the health of the control channel(s) between two adjacent NEs to be monitored.
Link fault localization: Allows the localization of faults occurring in topological links between PXCs.
LMP has been designed to accommodate OOO switches (PXCs) with their limitations on in-band communication capabilities (i.e., overhead bytes cannot be used for communication). Thus, LMP functions are somewhat more complex than what is required for just ...
