Design and Implementation of Network Performance Measuring and Evaluation System Based on Distributed n∶n Equal Evaluating Model

在对现有网络性能评价模型进行分析的基础上 ,提出了一种新的分布式n∶n对等评价模型 ,并着重讨论了它的基本工作原理、评价模型和系统结构 ,包括模块划分、报文格式以及测量方案等。通过对总线型局域网的实际测量结果进行分析 ,表明所得到的结论与理论分析结果是一致的。由于采用了这种分布式对等评价模型 ,使得整个评测系统具有精度高、适应性强、可扩展性好等特点。

On the basis of a thorough analysis of existing network performance evaluating models, this paper puts forward a new distributed n∶n equal evaluating model. It details the principle, the evaluating model and system structure, including module compartmentalization, message format and the measuring scheme, etc. The analysis of experiment results shows that the outcome of practical measurement on Ether-LAN fits in well with the theoretical analysis. Owing to this distributed evaluating model, the evaluating system can get several good features, such as high precision, good adaptability and good extensibility.
