Abstract: When a path which is a network communication path is calculated, the amount of path calculation is reduced while satisfying the requirement of the path. The network is logically divided into a plurality of calculation domains, and the divided calculation domains are hierarchically managed, and the path attribute of a path within the calculation domain of a lower hierarchical layer is held as a link attribute of an abstract link of a higher hierarchical layer.

Abstract translation: 当计算作为网络通信路径的路径时，减少路径计算量，同时满足路径的要求。 网络在逻辑上划分为多个计算域，划分的计算域被分层管理，并且较低层次的计算域内的路径的路径属性被保持为较高层的抽象链路的链路属性 分级层。
