In order to improve its performance,the remote device replication system is optimized.A design of remote device replication system is presented,which uses multi-thread parallel processing and pipelining technology.High-performance log and bitmap reduce the waiting time for application I/O operation.The replication system is based on a self-adaptive asynchronous device replication protocol and a fast request mergence strategy,which are able to reduce the time for net dispatching,and make the most of the net band for replica-tion.Experiments show that the replication system is able to improve the performance of replication evidently.
