To prevent communication between processes of different computers from being interrupted due to a trouble in one transmission route. A communication controller (1b) of a computer (1) selects at least one of communication devices (1c) and (1d) and establishes physical connections via the selected communication devices, in response to a connection request from a prescribed process. The communication controller (1b) defines the one or more established physical connections as a logical connection. When a trouble happens in a physical connection included in the logical connection, the communication controller (1b) establishes another physical connection via a communication device different from that of the troubled physical connection and includes this physical connection in the logical connection. When receiving a communication request applied to the logical connection, from the process, the communication controller (1b) performs communication via the physical connections included in the logical connection, in response to the communication request. <IMAGE> |
