摘要:
 传统TCP/IP协议栈要占用大量计算和访存资源，主要表现在中断上下文切换、协议处理和数据拷贝三方面。为减轻飞腾处理器计算负载，逐步采用软硬件一体化即协议卸载引擎( TCP/IP Offload Engine)技术，用硬件部分或全部实现TCP/IP协议处理。因飞腾平台处理器频率较低，网络负载较重时容易成为网络 I/O 瓶颈。文中对 TCP/IP 卸载引擎( TOE)技术及其相关原理进行研究，设计并实现了飞腾平台TOE协议卸载引擎的驱动，利用TOE对飞腾平台的网络性能进行优化。测试表明：飞腾平台使用TCP/IP卸载引擎能提高网络吞吐量并减少CPU利用率。
Abstract:
 Traditional TCP/IP protocol stack takes a lot of computation and memory access resources,mainly in the aspects of interrupting context switch,protocol processing and data copying. In order to reduce the computational load of processor,phased integration of hard-ware and software that is protocol offload engines (TCP/IP Offload Engine) technology,use some or all of the hardware to achieve TCP/IP protocol processing. FT processor’s frequency is low,when the network load becomes heavy,it easily becomes a network I/O bottlenecks. Introduce the principle of TOE,and design and implement the TOE driver on domestic platform,optimizing network perform-ance on FT platform by TOE. Tests show use of the TCP/IP offload engine significantly improves network throughput and reduces CPU utilization.
