网格环境下的故障检测服务研究

Research on Failure Detection Service in Grid Environment

研究网格环境下的故障检测服务问题。从识别网格环境对故障检测服务的特殊需求出发，研究了网格环境下故障检测服务的实现机理，并对现有实现方法的优缺点作了深入比较，指出现有方法在满足网格特定需求方面的缺陷，提出设计动态自适应故障检测服务的重要性。在此基础上，通过对分布式系统中已有动态自适应故障服务的分析，提出了工作思路，为今后的深入研究指明了方向。

This paper studies on the issue of failure detection service in grid environment. Firstly, we identify the special requirements for failure detection service in grid environment. Then, research the implement mechanism of failure detection service, and compare the existed methods in detail. On this basis, we present the importance of adaptive failure detection service. At last, we propose the future research direction by analyzing existed adaptive failure detection service in distributed systems.
