Routing Information Processing Technology of Switch Based on Hierarchical Scheduling Algorithm

To meet the needs of efficient processing of switch routing information,this paper studies the technology of the switch routing information processing based on hierarchical scheduling algorithm.In the paper,the system is configured based on the plug-in switch interface,and on this basis,the function module of the switch routing information processing is elaborated to facilitate large-scale exchange of the unit network information.To avoid the communication delay caused by the communication blocking of the routing information processing process and maximize the system performance,the paper proposes a hierarchical scheduling algorithm for real-time scheduling of the switch information processing process.In addition,in order to calculate the optimal solution of hierarchical scheduling algorithm for efficient configuration of switches,particle swarm optimization algorithm is used to search the optimal solution of hierarchical scheduling function.The system test results show that the proposed hierarchical scheduling scheme can effectively reduce the communication delay of the switch and improve the processing ability of the switch routing information.
