LMP
(ONS 15454 SDH only) The Link Management Protocol (LMP) manages traffic engineering (TE) links. Traffic engineering encompasses traffic management, capacity management, traffic measurement and modeling, network modeling, and performance analysis. Traffic engineering methods include call routing, connection routing, quality of service (QoS) resource management, routing table management, and capacity management. In short, TE links are designed to define the most efficient paths possible for traffic to flow over a network and through the Internet.
LMP manages TE links between peer nodes, such as two Calient PXCs. Peer nodes have equivalent signaling and routing. LMP also manages TE links between a node such as a Calient PXC and an adjacent optical line system (OLS) node. An example of an OLS node is an ONS 15454 DWDM node. Networks with routers, switches, optical cross-connects (OXC), dense wavelength division multiplexing (DWDM) optical line systems (OLS), and add/drop multiplexers (ADM) use a common control plane such as Generalized Multiprotocol Label Switching (GMPLS) to dynamically provision resources and to provide network survivability using protection and restoration techniques. LMP is part of the GMPLS protocol suite.
