METHOD FOR CONTROLLING INTERNAL CONNECTIONS AMONG FORWARD ENGINES IN MPLS LER SYSTEM HAVING DISTRIBUTED FORWARD ENGINES

摘要

The forward engine The present invention for a multi-protocol label switching (MPLS) system of the label edge router (LER) system including a plurality of forward engine, shape management unit generates the shape information to determine the shape of the forward engine, connecting the liver to the full-mesh and produces a full-mesh information for the internal connection between the forward engine. Resource management unit inside between the pool and stores the mesh information to the full-mesh table, the forward engine related to the label switch path (LSP) or external connection to the subscriber receiving providing the shape information and the full-mesh information from the shape management using the primary connection information for connecting to generate and release the details of the internal connections. Connection processing in response to the external connection request to the label switch path or a subscriber provides the primary connection information for making internal connections associated with the external connection to the resource management unit, and provides the detailed information received from the resource managing unit to said forward engine . The present invention is to enable a process of rapid, while using a minimum of memory resources, regardless of the number of LSP / subscriber connection and connection release.
