摘　　要：针对服务功能链(service function chain,SFC)请求动态变化导致的航空信息网络中平台负载不均问题,提出了一种基于联盟博弈的SFC迁移算法。该算法将航空平台作为博弈参与者,将SFC实例作为博弈商品,以网络能耗和迁移开销联合优化为目标。在算法执行过程中,各航空平台之间相互协作构建博弈联盟,通过联盟之间的比较与交换行为实现SFC迁移及网络资源整合。研究结果表明,所提算法具有较低的计算复杂度、较好的收敛性且能够形成纳什稳定结构。此外,在不同的网络规模下,所提算法均能有效降低网络能耗及网络迁移开销,同时保持较高的不同规模网络的资源利用率。In order to solve the load imbalance problem in aviation information network caused by the dynamic changes of service function chain(SFC)requests,a coalitional-game based SFC migration algorithm is proposed.The algorithm regards the aviation platform as the game player and the SFC instance as the game good,which aims to achieve the joint optimization of the network energy consumption and migration overheads.During the execution of the algorithm,the aviation platforms collaborate with each other to build game coalitions,and achieve the SFC migration and network resources integration through the comparison-and-swap operation between different coalitions.The experiment results show that the proposed algorithm has low computational complexity,good convergence performance and is capable to form the Nash-stable structure.Besides,the algorithm can effectively reduce the network energy consumption and migration overhead while maintaining the high resource utilization in different network sizes.
