摘要： TCP/IP协议是网络传输的基础协议，嵌入式系统TCP/IP协议的性能测试对相关产品的研发具有重要的意义。该文通过对PC和嵌入式系统PXA255、AT9200的链接进行数据包发送测试，分析了嵌入式TCP/IP协议的各种开销，获得优化的服务器数据传输尺寸。估计了嵌入式系统所能达到的最大TCP/IP传输速度，并找出影响TCP/IP性能的关键因素和瓶颈。

关键词: 嵌入式系统, TCP/IP, 性能

Abstract: TCP/IP is the basic protocol in data transfers over networks, and the performance evaluation of TCP/IP over embedded systems has great significations to the study and development of correlative production. In this paper, the data packet sent through the link between PC and embedded systems PXA255 and AT9200 is tested, and all kinds of TCP/IP in embedded systems are analyzed, the optimal data size of server transfers is obtained. Furthermore, the maximum transmission speed of TCP/IP over embedded systems is estimated, and the critical factors and bottlenecks which impact the performance of TCP/IP are found out.

Key words: embedded systems, TCP/IP, performance
