| 摘 要： | 2PC协议具有广泛的适用性,但存在易于阻塞和时间延迟的缺点。文中提出了一种改进的基于多站点备份的1-2PC协议。该协议利用＂多站点备份＂技术和＂心跳＂技术可减少分布式事务信息交换的次数,降低事务发生阻塞的概率,缩短事务成功提交的时间,从而改善了提交协议的性能。通过性能比较和分析,证明了提出的协议具有高效性和低阻塞性。

| Abstract: | The two-phase atomic commit protocol is widely used,but it is easy to block and has a substantial time delay.In this paper,an improved one-phase,two-phase commit protocol based on multi-site backup is proposed.The protocol uses ＂multi-site backup＂ technology and ＂Heat-Beat＂ technology which can decrease the times of information exchange,lower the probability of blocking in transactions,shorten the time of submitting a transaction successfully and improve the performance of the commit protocol.By comparing and analyzing the performance,the result shows that the proposed protocol is efficient and low blocking. |
