Scheduling Strategy of Aviation Information Network Service Function Chain Requirements

The low resource utilization efficiency may be caused by service burst, dynamic change of topology structure and limited resources in aviation information network (AIN) scenario. A service function chain scheduling algorithm for network function virtualization is proposed for the efficient scheduling of service function chain requirement (SFCR) . The algorithm is mapped according to the correlation between SFCR and the platform, thus improving the processing efficiency of server, effectively reducing the number of virtual network function (VNF) instantiations, and integrating the platform resources. In considering the impacts of delay and traffic, the network function instances are integrated and migrated to reduce the network energy consumption and improve the resource utilization. The simulated results show that the proposed approach has better optimization performance in terms of the number of running platfors, SFCR acceptance ratio, and the network resource consumption while guaranteeing the delay requirements, which is suitable for solving the SFCR scheduling problem in AIN scenarios. © 2024 China Ordnance Industry Corporation.
