NETWORK COMMUNICATION SYSTEM, SERVER SYSTEM, AND TERMINAL
First Claim
1. A network communication system comprising a server system connected to a network, and a terminal connected to the network and having a predetermined connection authority to the server system,wherein the server system includes a plurality of servers, each server having a different IP address set thereto, and performing a predetermined process in response to a connection request from the terminal 1, andwherein the terminal includes a connection destination list storage unit that stores information concerning a preset prioritized connection order of connection with the server, fault determining means that determines whether a traffic fault occurs on the server when a connection request is made to the server, and priority order setting means that changes connection to a next server in accordance with the connection order if the fault determining means determines that a traffic fault occurs on the server.

Abstract
A network communication system includes a network, a system of authentication servers, and a terminal. The system of the authentication servers includes a plurality of servers that execute a predetermined process in response to an authentication request from the terminal. The terminal includes a connection destination list storage unit that stores information concerning a preset prioritized connection order of connection with the server, fault determining means that, when an authentication request is made to the server, determines whether a traffic fault occurs on the server, and priority order setting means that, if the fault determining means determines that a traffic fault occurs on the server, changes connection to a next server in accordance with the connection order.
