摘要

作为欧洲信息技术研究战略计划(ESPRIT)的一部分，Delta-4项目正在寻求定义一个开放的、容错的分布式计算架构。Delta-4容错方法基于在不同主机上复制软件组件。主动和被动复制策略都包含在Delta-4的框架中。介绍了被动复制范式中使用的机制背后的原理。在Delta-4方法中，向后错误恢复是通过将检查点与进程间通信集成来实现的。这种方法被认为既适用于确定性程序，也适用于非确定性程序。本文还描述了在整个Delta-4框架内实现这样一个系统的方法

Using passive replicates in Delta-4 to provide dependable distributed computing

As part of the European Strategic Programme for Research in Information Technology (ESPRIT), the Delta-4 project is seeking to define an open, fault-tolerant, distributed computing architecture. The Delta-4 approach to fault tolerance is based on the replication of software components on distinct host computers. Both active and passive replication strategies are contained within the framework of Delta-4. The philosophy behind the mechanisms used within the passive replication paradigm is presented. In the Delta-4 approach, backward error recovery is achieved by integrating checkpointing with interprocess communication. This approach is seen to be applicable to both deterministic and nondeterministic programs. A description is also given of the implementation of such a system within the overall Delta-4 framework.<>
