  • Power optical transmission route and spectrum allocation method based on elastic optical network
    Patent number: 11323333
    Abstract: Disclosed is a power optical transmission route and spectrum allocation method based on an elastic optical network, including: determining a set of alternative routes among nodes of a power communication network according to power communication topology; coloring the routes for classification, determining a total number of colors allocated, and determining the coloring of the set of alternative routes according to a hop count of route nodes and the total number of colors of spectrums; proportionally classifying the spectrums into blocks according to the total number of colors allocated and the number of route classes allocated to each color; selecting an optimal solution from the set of alternative routes by comprehensively considering a switching hop count and a network-wide risk balance value, to determine a route to execute service allocation; and determining positions of spectrum blocks according to the route selected and the allocated colors, to complete spectrum allocation.
