摘要
由于应用场合的固有特点,嵌入式以太网有区别于普通局域网的基本特征,计算机局域网时延分析的一般结论并不完全适用,必须根据嵌入式应用的基本特征具体分析其时延特性。分析了影响以太网实时性能的主要因素和嵌入式以太网的基本网络特征,建立了嵌入式以太网的仿真模型,采用动态仿真方法具体分析了各种网络参数对嵌入式以太网链路延迟的影响。
Embedded Ethernet is distinct from local computer network because of its inherent characteristics arising from application.The general conclusion about link delay of local computer network does not hold true for embedded Ethernet.lt is necessary to analyze embedded Ethernet delay characteristic according to application particularity.This paper concludes the factors affecting the real-time performance and the specialty of embedded application.After that,the simulation model of embedded Ethernet is built up using OPNET software.And then the affection of network parameters on link delay is studied by simulation.
