METHOD FOR PROCESS MIGRATION BETWEEN NETWORKS AND NETWORK SYSTEM THEREOF

摘要

[PROBLEMS] To eliminate service use stop and communication resetting by a user when operating server switching such as process migration is performed. [MEANS FOR SOLVING PROBLEMS] When server/network linkage control means (2) receives a session migration start request, it issues an operating server switching control start report to operating server switching control means (3) (step S702). The operating server switching control means (3) receives the operating server switching control start report and performs switching of the operating server. Next, the server/network linkage control means (2) receives the operating server switching control end report and transmits a connection destination target network switching request to connection control means (4) (step S707). The connection control means (4) switches the connection destination target network of a user corresponding to the user name to be subjected to the connection destination target network switching, from the target network including the main server to the switching destination target network including the backup server (step S708).
