METHOD AND APPARATUS FOR GENERATING PHYSICAL NETWORK TOPOLOGICAL GRAPH

摘要

A method and apparatus for generating a physical network topological graph, relating to the field of communications. The method comprises: a gateway node obtains data transmission parameters between a first-level node and nodes in a first node set, the first-level node being located in a first-level power distribution device in a power distribution network, and the first node set comprising nodes located on other-level power distribution devices other than the first-level power distribution device in the power distribution network; determine, from the first node set according to the data transmission parameters between the first-level node and the nodes in the first node set, a second-level node directly connected to the first-level node; and generate the physical network topological graph of the power distribution network, the physical network topological graph comprising a connection relationship between the first-level power distribution device where the first-level node is and the second-level power distribution device where the second-level node is. The efficiency of generating the physical network topological graph can be improved, the hardware cost is reduced, and occurrence of a hidden danger in the power distribution network is avoided.
