一种基于复制组管理的移动agent容错模型

A Mobile Agent Fault-tolerant Model Based on Replica Group Man agement

可靠性是影响目前移动agent应用扩展的一个关键问题之一,现有的分布式系统的容错方法不能完全照搬,该文提出一种基于复制组管理的移动agent容错模型ReGFatoM,通过改进已有的阶段构建模式以及加强复制组管理来提高系统的可靠性,实验表明,ReGFatoM能够有效解决诸如“只一次”执行、阻塞、网络分割等容错问题,而且具有模块化、效率高的优点。

Reliability is one of the key problems which could influence the application of mobile agents.While existing fault-tolerance techniques are not applicable perfectly in mobile agent systems ,a mobile agent fault-tolerance model called ReGFatoM is presented in this paper.It could effectively enhance the reliability of the whole system through dynamic staging mode and efficient replica group management.Simula experiments show that the ReGFatoM could solve many problems like'exactly-once'execution,blocking,network partition etc,but also owns the property of modularity and high efficiency.
