ABSTRACT:
There is disclosed a system and a method for isolating faults and recovering a distributed system of the type including a plurality of modules to optimized operation. At least some of the modules are active fault recovery modules and include fault detecting means for initializing a fault check routine and sensing faults within the distributed system. Voting means are associated with each active module for placing a vote during each fault check routine in response to a detected fault. Collective vote determining means record the votes of the active modules after each fault check routine and recovery sequence initializing means initializes a fault isolation and recovery sequence in response to a given number of consecutive collective votes exceeding a predetermined value.
