容错中间件的研究

Research of fault-tolerant middleware

容错是实现分布式系统可靠性和可用性的重要手段。文中容错中间件为分布式系统提供容错基础设施,结合了中间件技术的优点,提高了分布式对象容错,简化了分布式系统容错的开发。同时阐述了运用反射原理实现动态配置容错策略,来满足各种分布式系统的容错要求。

Fault-tolerant is an important way to implements reliability and availability of the distributed system. The fault-tolerant middlewar e mentioned in the article is a fault-tolerant infrastructure of the distributed system. It combines the advantages of the middleware technologies and enhances the fault-tolerance of the distributed objects. It also expatiates the implements of dynamic deploying of the fault-tolerant strategy using reflection principle to meet the needs of all kinds fault-tolerant of distributed systems.
