分布式冗余服务管理系统中的管理信息收集策略

Strategies on Information Gathering in Distributed Redundant Server's Management System

使用冗余服务来提高分布式系统的可靠性、可用性及吞吐能力已成为分布式应用的研究热点。文章在提出一个基于Agent的冗余服务管理模型的基础上，详细分析了为了更好地实现系统的冗余管理功能，几种必要管理信息的收集策略，并通过比较，选择较优策略。

In order to improve the reliability,availability and throughput,redundant server becomes a hot spot in distributed application.This paper suggests a redundant management model based on Agent,and makes a thorough study on several information collection strategies being necessary for information management to better facilitate redundant management in distributive systems.In addition, a comparison among the different strategies is made for singling out the best adoption.
