Abstract

The present disclosure provides a path selection method and apparatus. The method comprises: receiving a traffic scheduling request, wherein the traffic scheduling request comprises a requirement for path selection, a source node, and a destination node; determining, for each dedicated line cloud comprising both a source virtual node connected with the source node and a destination virtual node connected with the destination node, a dedicated line corresponding to the dedicated line cloud as a traffic forwarding path when static attribute of a link between the source node and the respective source virtual node and a link between the destination node and the respective destination virtual node, and/or a dynamic attribute of a link between the respective source virtual node and the respective destination virtual node satisfy the requirement for path selection. The present disclosure can implement path selection based on bandwidth and quality in a point-to-multipoint network by a controller.
