基于虚拟实验方法的滑动窗口协议分析

随着网络技术的飞速发展，如何定量地分析网络的原理，无论对于研究者还是学习者都是十分重要的。建立虚拟网络实验室，是当前网络与研究的设计的先进方法，它的应用使得建立低耗费的复杂网络系统测试平台成为可能。本文通过基于虚拟实验的方法，对三种典型的滑动窗口协议进行分析，用面向对象的方法建立了一个虚拟实验模型,包括体系和主要的类的设计，并介绍了该模型的其他特点。最后通过一些典型的实例具体的描述了滑动窗口协议虚拟实验的过程。并根据实验结果分析了这三种滑动窗口各自协议的特点和性能。

Study on Sliding Window Protocols by the Method of Virtual Experiment

With the rapid development of network technique, it is important for either researchers or learners to analyze principles of network quantitatively. Constituting virtual network laboratory, an advanced method to study and contrive network nowadays, makes it possible to construct test platform for complex network system with low expense. This paper presents a study on three typical kinds of sliding window protocols by the method of virtual experiment. A model of virtual experiment is constructed by object-oriented method, including architecture and main classes. Other features of the model are also presented. The course of the virtual experiment is described by some typical examples. At last, characteristic and performance of those three sliding window protocols are analyzed based on the result of experiment.
