Abstract: Aiming at the problems of low utilization of network resources and inconvenient searching of nodes in the current ASON network, an optimized design scheme of power dispatching data network based on ASON is proposed. This solution introduces aspects of network structure planning, service routing planning, and network fault diagnosis, focusing on the optimization design of service routing planning. The PageRank algorithm is integrated into the ASON network, and the PageRank calculation unit is used to perform continuous iterative calculations until the user can search for the best target network node according to the set path, and then output more stable network data information. The matrix equation makes the calculation data more accurate, thereby improving the optimization capability of the multi-layer ASON network, saving network resources, and improving the utilization of network information. The experiments show that the scheme designed in this paper can greatly increase the resource utilization rate of the ASON network, and also improve the average network revenue, which has good practical value.
