  • Replicated control block handles for fault-tolerant computer systems
    Patent number: 6704884
    Abstract: In a fault-tolerant system employing software fault-tolerance techniques, the identifiers used for control blocks or objects referenced on an interface between two co-operating partner software processes either require resynchronization after fail over of one or both of the partners or impose unwanted performance impacts on normal operation of the system. Replicated handles enhance the techniques currently used in such systems to avoid both the need for resynchronization and other potential performance impacts of the prior art.

  • Automatic reconnection of partner software processes in a fault-tolerant computer system
    Patent number: 6629260
    Abstract: In a fault-tolerant system employing software fault-tolerance techniques, automatic reconnection of partner processes after a failure of one or more of the partner processes requires that the partner processes are aware of the redundancy strategy employed by their partners. The present invention insulates the partner processes from the need for this knowledge, and also enables automatic reconnection between partner processes running in different parts of a heterogeneous distributed system.
