摘要: We describe a fault tolerance framework for CORBA that provides management and core services, implemented above the ORB ease of use customization, mechanisms, beneath transparency efficiency. Strong replica consistency is facilitated by multicast engine reliable totally ordered delivery messages to replicas an object. Transparency application allows programmers focus on their applications rather than tolerance, ORE existing commercial ORBs be used without modification. The adheres CORBA's objective interoperability ensuring different implementations specifications can interoperate non-fault-tolerant objects interwork with fault-tolerant objects.
