| 摘 要： | 由于互联网路由存在不对称的特点，即“源-宿”方向和反方向路由路径的不一致，使得已有的拓扑发现算法存在路径丢失问题。增加测量点会增加流量负荷。利用源-宿双向测量的方法，解决了拓扑发现中的路径丢失。实验结果表明该算法不仅可以获得较高的发现率，还具有网络流量负荷小的特点。

| Abstract: | The no-symmetrical existing in networks routers means that ＂source-destination＂ and ＂destination-source＂ router links are not always equal during topology discovery.It makes route-lost problem.Adding measure nodes can cause large flow.This paper proposes a method that it uses bidirectional way to discover the link which is hidden.Experiment show this algorithm can find more links than other algorithms in same conditions,can cause less-load in network and can be fit for large-scale networks. |

| Keywords: | topology discover multi-measure bidirectional way topology |
