Fault Diagnosis and Automatic Reconfiguration for a Ring Subsystem

Abstract A ring subsystem has been developed for a full-scale high performance heterogeneous computer network. The design goals and the implementation issues of the automatic reconfiguration of the ring subsystem are presented. Particular emphasis is laid upon reliability improvement techniques, based on duplication of the ring subsystem components, and the automatic reconfiguration algorithm, which determines network configuration when faults occur.
