LOAD DISTRIBUTION SYSTEM, NODE DEVICE, LOAD DISTRIBUTION DEVICE, LOAD DISTRIBUTION CONTROL PROGRAM, LOAD DISTRIBUTION PROGRAM, AND LOAD DISTRIBUTION METHOD

摘要

A layered load distribution system (1) including one or more nodes (11-13, 21, 31-39, 41-43, 51-59) in each layer. Load distribution information on each of all nodes (11-13, 21, 31-39, 41-43, 51-59) included in the layered structure is integrally managed in one node (11-13) among these nodes. Where the load distribution information represents either the number of processes that have been received and the number of processes that have been implemented at each of nodes to which a process request is distributed, the connection state and the load state of each of the nodes to which a process request is distributed, or the load distribution method implemented in the load distribution nodes.
