INTERNET LOAD-DECENTRALIZED RELAYING CONNECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To decentralize the load on a plurality of authentication service GW devices and to make a large number of IPsec connections from dial-up terminals. SOLUTION: Multiple authentication server GW devices which terminate IPsec are installed, a load decentralizing device which administers the authentication server GW devices (monitors their life/death states is placed), and a reception server is provided so that authentication server GWs are seen from a terminal side as if there were one authenticating server GW. The reception server monitors the life/dead state and use state (number of connections) of the load distributing device to send the address of an authentication server GW back to the terminal.
