摘要: 为克服TCP/IP协议多次拷贝和上下文切换导致网络存储系统性能低下的问题,提出一种轻量级数据传输协议——高速磁盘存储协议HDSP。HDSP协议借鉴零拷贝技术设计思路,通过精简层次、缩短数据复制次数和高效的流控机制来提高网络存储系统的吞吐率、降低系统负担。测试结果表明,HDSP在局域网存储系统环境中比TCP/IP协议具有更好的性能表现。

Abstract: To overcome the deficiency of the poor performance caused by multi-copy and context switch in TCP/IP,this paper introduces a light weight transport protocol which is referred to High performance Disk Storage Protocol(HDSP).Like the zero-copy technology,HDSP improves the throughput of networked storage system and reduces the system workload by reducing protocol layers and data copy times,and employing efficient flow control.The test result shows that HDSP has better performance than TCP/IP under Ethernet storage environment.
