SERVER SYSTESM FOR INTERNET

摘要

PROBLEM TO BE SOLVED: To decentralize access in a server group and back up data against fault occurrence without forcing a user to do special operation by selecting an optimum server which sends information out of one information transmission server group each time the information transmission server group is accessed. SOLUTION: This system has information transmission server groups 1091-109N which send information over the Internet 111 and a management server 101 which manages access from terminals. The information transmission server groups 1091-109N each consists of servers having the same information. The management server 101 has a management table containing host names given to the server groups 1091-109N and the communication addresses and selection information of the respective servers. When a communication address corresponding to a host name is requested, one of the communication addresses stored in the management table is selected and sent to the request source according to the contents of the selection information.
