| 摘 要： | 基于冗余的入侵容忍数据库是由多个异构数据库服务器组成的,通过增加冗余单元实现数据库的可生存性和可用性,但是冗余会引起系统性能下降.为提高系统性能,必须解决选举和数据库同步问题,这需要有效的算法及复杂周密的同步协议来实现.给出了多种可行的选举算法和一种动态同步方案,能够很好地解决数据库之间的选举和同步问题.

| Abstract: | The intrusion tolerance database based on redundancy is made of several isomerous database servers. And by adding redundancy cell, it achieves the survival and availability of database. But at the same time, redundancy makes the performance of system decline. In order to increase the performance, must deal with the problem of voting and database synchronization. Several voting algorithms and a synchronous scheme are presented, which could effectively deal with the problem and increase the efficiency of intrusion tolerance database. |
