Routing optimization method based on SDN context awareness

The invention discloses a routing optimization method based on SDN context awareness, and the method comprises the following steps: 1, collecting the related context data of a network and a user, andbuilding a network context data set; 2, constructing a three-level cascaded neural network model composed of a gating cycle unit, an auto-encoder and a multi-layer sensing mechanism; 3, inputting thenetwork scene data set in the step 1 into a trained graph neural network model for scene awareness to obtain a network performance matrix after scene awareness; and 4, optimizing the routing of the network through an intelligent algorithm according to the network performance matrix obtained in the step 3. Compared with other routing optimization methods, the routing optimization method based on SDN context awareness has the advantages that intelligent fitting of actual scenarios and state requirements can be better achieved, and the resource utilization rate of the network is increased. 本发明公开一种基于SDN情景感知的路由优化方法，包括如下步骤：步
