Government and enterprise private network architecture planning method and device and readable storage medium

The invention provides a government and enterprise private network architecture planning method and device and a readable storage medium. The method comprises the following steps: acquiring government and enterprise oriented ToB values of each infrastructure node in a local network infrastructure according to a stock government and enterprise private line; according to the order of the ToB values from large to small, one or more previous infrastructure nodes are selected in sequence to serve as ToB target architectures, N ToB target architectures are obtained, and N is larger than or equal to 1 and smaller than or equal to the number of all infrastructure nodes; calculating the coverage ratio and the average access distance of each ToB target architecture in the N ToB target architectures to the stock government and enterprise special line; and selecting a proper ToB target architecture as a final ToB target architecture of the government and enterprise private network according to the coverage proportion of
