A Recovery Technique for Distributed Communicating Process Systems

This paper presents a recovery technique for distributed communicating processsystems.It handles both hardware faults and software faults uniformly.Differing fromother recovery techniques,it brings an extremely small amount of execution overheadto nonfailing processes and can be implemented easily.It can be applied to aprogramming procedure to mask the software design errors or imbeded into anoperating system to enhance the reliability of the whole system.The theoretical workis carried out first,then the implementation problems are considered and theevaluation techniques are discussed last.
