The invention discloses an MSTP network architecture in an electric power communication network, which comprises a kernel layer, a backbone layer and an accessing layer. The kernel layer comprises a plurality of center stations and reserved ones with the center stations forming a looped network; the backbone layer is configured to use the super-high voltage power transformer station as the kernel ring and to access the equipment group of some center station in the kernel layer to form a plurality of independent backbone rings; and the accessing layer is configured to use the edge power transformer stations and the prefectural and municipal companies as nodes and to form different access points that access the backbone rings in the backbone layer through a plurality of network elements so as to access the nodes of the kernel layer; and the center stations and the reserved ones are all deployed with gateway servers. Through the data network channels, dual machine heat equipment is formed. The kernel layer and the backbone layer access the routers of the gateway data network through outer channels, and the kernel layer selects a plurality of network elements as the gateway network elements. With the method, it is possible to effectively increase the network survival performance of a hybrid network.
