%X As the development of high-speed network technology and rising demand for high-frequency trading, upgra- ding trading speed has become the main focus of e-commerce trading system providers in recent years. Primary-backup replication based on shared storage is a classical approach to ensure high availability and data durability of trading sys- tans at present, but it is difficult to further reduce the system latency due to its persistence bottleneck. ho solve this problem,a Paxos-based approach for memory data replication was proposed and illustrated in the stock trading context. hhe approach accomplishes the primary-backup replication through messaging, can ensure the strong consistency of data replicas and tolerate possible benign failures. Experimental results show that compared with the shared storage replica- tion approach,this approach reduces the order processing latency of stock trading system from several milliseconds to several hundred microseconds in 10 Gbit Ethernet, and achieves hot failover correctly in lure. case of the primary host fai
