<p>A migration program which reduces a service suspension time, ensures access transparency and position transparency, and enables normal operation without degrading the performance. When processing is migrated from a source computer (2), an operating reception block (1a) receives an operating system program through a network (6). An execution information reception block (1b) receives execution information needed to resume a process of the source computer, through the network (6) from the source computer (2). An address reception block (1c) receives a floating MAC address assigned to the source computer (2) in addition to the inherent MAC address, from the source computer (2). A processing block (1d) executes processing to restore the state of the source computer (2) in accordance with the received operating system program and execution information, and performs subsequent communication by using the received floating MAC address of the source computer (2).</p> |
