ABSTRACT:
A communication network switching device is provided between a client and a server as a intermediary mechanism to estimate a traffic and to issue a switching request for communication networks. Two switching devices include units for releasing a session in cooperation with each other and units for resuming the session in cooperation with each other. The client switching device includes a unit for connecting to a communication network to which the communication is to be switched after the session release is complete and for acquiring a new communication address assigned through the connection and a unit for notifying the server switching device of the acquired communication address. The server switching device includes a unit for identifying a server pointed to by a port number specified in a service request to transfer the service request and a unit for acquiring the new communication address acquired by the client switching device.
