Abstract

A connection from first terminal CL, Clto m of relay servers RSto RSis performed and a connection from second terminal CL, CLto n thereof is performed to relay a communication between the terminals with one of the relay servers connected in common to both of the terminals set to be an active relay server. If a failure occurs in the active relay server, the other relay server connected in common to the first terminal and the second terminal is searched to relay a communication between the terminals with the relay server set to be an alternative relay server at the first terminal and the second terminal. Consequently, a data communication between the terminals is performed through the relay server selected optionally, and furthermore, adjustment for determining the alternative relay server is performed on the terminal side if a failure occurs in an active relay server.
