摘　　要：以一个基于嵌入式Internet技术的网络POS机为例介绍了一种评估嵌入式系统网络性能的方法.该方法的具体实现策略是,在一个网络POS机系统(一个以Webit为处理器的嵌入式系统)中应用单服务窗等待制M/M/1排队模型测试和评估Webit的网络性能.这些性能包括,Webit在网络上的工作效率、通信质量以及网络拥赛的控制等,从而确保整个系统的稳定性.此方法有助于设计嵌入式信息家电等嵌入式网络产品的编程人员进行调试工作,同时还可用于信息家电性能评估.This paper presents a Network POS based on embedded Internet technology which illustrates a way of evaluating the network capability of a embedded system.Detailed method for the way is that the network capabilities,such as the work efficiency,the communication quality and the controlling for network congestion and so on,are evaluated by a single service window′s waiting strategy which is M/M/1 queueing model in a Network POS system.All the things can insure the stability of systems.This way can help those programmers who are designing embedded network products such as household information appliance debug the program.At the same time,the way can apply for evaluating the capability of household information appliance.
