PROBLEM TO BE SOLVED: To ensure the continuity of the communication even after the migration.SOLUTION: A physical server executing a virtual FW relays the communication between a first node and a second node connected with each other through a plurality of relay devices. A physical server, to which processing for relaying between the first node and the second node is to be migrated from another computer, generates control information indicating that the communication from the second node to the first node should go through that physical server, and then transmits the generated control information to the relay devices. |
