Title: Dynamic information bus generation method and sub- network management process
Inventor: KURITA TOSHIHIKO
IPC: H04L12/46
Filed: 1999-11-30
Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To reduce the internal volume of a housing and thereby miniaturize a connector without increasing the number of components by folding a flat spring part or the multiple folded parts of the spring part after blanking at a virtual bending line along the expandable direction of the spring part. SOLUTION: A metal plate is blanked and then the multiple folded parts located at both sides of a flat spring part 22 are folded at a virtual folding line along the expandable direction E of the spring part 22.
