基于组通信技术的同步复制方法的研究

Research of Eager Replication Methods Based on Group Communication Technology

针对同步复制方法本身的缺点提出一种新的研究思想,即引入组通信技术。利用组通信技术中关于转发信息的定序性质,借助于类队列的并发控制思想,很好地解决了复制领域中的数据一致性及通信量的问题。

In order to overcome the inherent shortcomings of eager replication,group communication technology is introduced.With the help of ordering in messages delivery and the class queues of concurrency control,the problems of data consistency and communication overhead are well solved.
