Reliable and Efficient Routing Management Mechanism for Power Communication Network Based on Multi-party Cooperation

SDN technology brings the advantages of improving resource utilization and management efficiency to the network, and at the same time, it poses new challenges to the reliable operation of the network. In order to solve the problem of data forwarding error caused by network equipment attack, this paper proposes a multi-party cooperative routing management mechanism for power communication network. In order to achieve a reliable and efficient routing mechanism, a routing management platform architecture is designed according to the characteristics of the network. The architecture includes four types of devices: blockchain, centralized management center, SDN controller and repeater. In the routing table generation stage, a blockchain-based routing table audit mechanism is proposed. In the routing table execution phase, a routing table detection mechanism based on active detection is proposed. In the performance analysis, from the two dimensions of blockchain management routing table, centralized management center and SDN controller collaboration, it is verified that the mechanism in this paper has good performance in improving routing reliability and efficiency.
