DYNAMIC INFORMATION BUS GENERATION METHOD AND SUB- NETWORK MANAGEMENT PROCESS

摘要

PROBLEM TO BE SOLVED: To dynamically construct a logical multicast network to efficiently use computer respires and network resources with respect to a dynamic information bus generation method. SOLUTION: A field management process FM is placed on a network, and a field client process FC is placed in each of hosts 1 to 3, and a sub-network management process SM is placed in each sub-network. When the field management process FM receives an information bus generation request as a communication means between a plurality of terminals on the network from a user through the field client process FC, the field management process FM determines a connection point between sub-networks and instructs the sub-network management processes SM corresponding to the connection point to set multicast tunneling, and then multicast tunneling is set, and each terminal designates a multicast address to send data, and thus an information bus supporting communication between groups is dynamically generated.
