A sender processor unit 101 transmits a packet to which a logical address of a receiver processor unit is added. Network routers 102 to 108 obtains a physical address corresponding to a destination logical address by referring to a processor address translation table 122 through a signal line 140, sets a route 112 and transfers the packet to a receiver processor unit 107. When a fault is caused in the receiver processor unit 107, a service processor changes correspondence of logical addresses to physical addresses of the processor address translation table 122. Consequently, a route 113 to a substitute processor unit 105 is dynamically |
