Each ActivatedRoute in the RouterState provides methods to traverse up and down the route tree to get information from parent, child and sibling routes.

路由器状态为我们提供了从任意激活路由开始向上或向下遍历路由树的一种方式，以获得关于父、子、兄弟路由的信息。

There are three parts in this thesis: In the first part, we give a new kind of representation of network with or without movement prohibitions, and a new shortest-route-tree algorithm is presented.

本论文分三部分：第一部分提出了一般网络（有禁行和无禁行）的一种新的表示法及其相应的广义性最短路树算法，并给出了这种算法的收敛性证明。
