基于飞腾平台TOE协议栈的设计与实现
Design and Implementation of TCP/IP Offload Engine Protocol Stack Based on FT Platform
摘要
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.关键词
