Replicated execution of distributed programs provides a means of masking hardware or software failures in a distributed system. Application level entities (processes, objects) are replicated to execute on distinct processors. Such replica entities communicate via message-passing. Non-determinism within the replicas could cause messages to be processed in non-identical order, producing a divergence...
Due to the message transmission between processes in a distributed system, an error in a process might be propagated to another via faulty messages, which causes a global failure. In the absence of built-in fault detection methods, rollback recovery approach is not useful. To avoid error propagation and rollback overhead, roll-forward recovery schemes based on redundancy techniques such as N-Version...
