Dynamic bandwidth allocation and management method and system for optical communication network

The invention provides a dynamic bandwidth allocation and management method and system of an optical communication network, and relates to the field of optical communication equipment management. Correspondingly collecting optical signal attribute characteristics corresponding to the optical signals in each target optical communication device; extracting corresponding optical signal flow mode characteristics; constructing a graph structure based on each optical signal attribute feature and each optical signal flow mode feature; updating each graph node in the graph structure based on the graph neural network; inputting the updated node features of each graph node into a network traffic prediction model so as to respectively output network prediction traffic corresponding to a future preset time period; and dynamically adjusting bandwidth resources according to the network predicted traffic of each target optical communication device. Therefore, by globally and dynamically adjusting the bandwidth resources, th
