TCP/IP协议卸载技术性能与实现的研究

Research on Performance and Implementation about TCP/IP Offload Technology

本文通过分析当前计算机系统主要通信瓶颈,建立模型分析其卸载后的性能,得出协议卸载与节点处理能力、网络带宽、网卡处理能力以及需要处理的应用程序、网络数据包的强度有关的结论,得出了他们之间理想状态下的最优解.建立并初步实现TOE通信平台,实现零拷贝,利用Linux开源特点实现相应的软控制程序并结合ML403开发板实现相应的硬处理功能,实现简单数据包的收发.

This paper analyses the main bottleneck in communication, and set up a model to research the performance with TOE. At last, we draw a conclusion： node processing capability, network bandwidth, NIC processing capability, overhead of application and network data, play an important role in protocol offload, and educe the Optimal point. Set up and implement the preliminary platform with TOE and Zero-copy, and we make use of the characteristic of Linux to implement the relating software, finally carry out the simple data transfer with ML403 development board.
