ABSTRACT:
A bank of processing units is connected to a number of LANs via a bank of MAC controllers. An interconnect switch allows any of the processing units to access any of the MAC controllers. A housekeeping processor periodically detects faults in the connectivity of the processing units to the LANs. When a fault is detected, a redundant processing unit is assigned to be connected to the LAN. If a fault still exists, then a redundant MAC controller is assigned to the redundant processing unit. The MAC address of the previous MAC controller is reassigned to the redundant MAC controller.
