摘要
A path selection method is provided, which includes the following steps. A middle domain determines a path cost of an inter-domain link from the middle domain to a destination node domain according to a received path cost of an inter-domain link sent by a source node domain, and then sends the path cost to the destination node domain. The middle domain receives an optimal service path from the destination node domain to a destination node returned from the destination node domain, in which the optimal service path is determined according to the path cost of inter-domain link sent by the middle domain, and determines an optimal service path from the middle domain to the destination node according to the received optimal service path and sends the optimal service path to the source node domain, for making the source node domain determine an optimal service path from a source node to the destination node according to the optimal service path sent by the middle domain. Accordingly, a network system and a path computation element are provided. The technical solutions can improve the efficiency of selecting the optimal service path.
