摘　　要：探讨了一种集中式、基于单个探测点的拓扑测量系统原型的设计与实现。在该原型中以数据采集为核心,设计了一组可扩展的探测模块,每个模块相对独立,从而使得系统可以很方便地加入不同的拓扑测量机制和技术,系统的灵活性和扩展性得以提高;同时在系统运行中引入了基于状态的拓扑更新策略,使得拓扑测量的结果具有相对较高的完整性和准确性。在实现时,充分利用了VC.NET的多线程技术,使拓扑测量的速度也得以提高。A centralized network topology measurement system is introduced, data collecting is the kernel. It is composed of several expandable, relatively independent detecting modules. This mechanism could make the system more flexible and easy to extend. Besides, a strategy for updating the data obtained during the process of topology measurement and multithread technique of VC. NET is used in our system. All of those methods have improved the system performance, especially veracity, integrality and speed.
