随着网络带宽的迅速增长,主机协议处理开销已经成为系统整体性能的瓶颈.近年来,在协议加速领域开展了大量的研究工作,主要分为协议处理机制、实现以及结构的优化.在分析了协议处理的开销与性能之后,从协议机制、实现和处理结构这3方面对TCP(transmission control protocol)加速技术的研究现状进行了总结,并分析了进一步的研究方向-With the rapid increment of network bandwidth, the overheads of protocol on host have become the bottleneck of system performance. A lot of work including optimization for protocol mechanism, implementation and architecture have been developed in the fields of protocol acceleration. After analyzing overhead and performance of the protocols, it is attempted to survey the developments of TCP (transfer control protocol) accelerating on mechanism, implementation and architecture. Finally, some future directions are discussed. Key words: protocol performance overhead acceleration mechanism implementation architecture
