基于响应时间的LAN系统性能评价

LAN network system performance evaluation based on response time

准确地测试LAN系统的性能参数是进行LAN系统性能评价的关键,网络性能参数通常包括响应时间、延迟、吞吐量、网络连通性、数据包可达性、帧传输效率和正确率、协议种类、帧碰撞率、流量等,网络的响应时间是所有性能参数中最重要的参数.提出了一种基于理论计算和实际测试相结合的LAN性能参数测试方法,该方法克服了以往测试方法中容易出现的不确定因素,使用得测试参数的一致性更好.

The key problem in LAN network performance evaluation is testing the network parameters accurately.Network performance parameters include the following:response time,delay,handing capacity,network connectivity,data packet reach ability,frame transform efficiency and correct ratio,protocol type,frame collision ratio and volume of flow etc.The response time is the most important parameter.In this paper,a useful method based on the combination of theory computing and practical measuring to test the network parameters is described.This method is much better in preventing the network parameters from being unstable,and can make the amiability better.
