中文摘要:
      当前有关研究软件定义卫星网络控制器静态部署方法忽略了卫星网络拓扑的动态性、用户数据流量的不稳定性。综合卫星网络的动态特性,基于软件定义卫星网络的架构,通过设定的三门限值,采用交换机迁移的方式,提出了一种改进鲸鱼优化算法(MWOA)的多控制器动态部署方法,有效地实现了多控制器动态部署。仿真实验表明:MWOA相比于其他算法,在交换机迁移开销、控制链路时延及负载均衡方面均有显著优势,该方法能够进一步提升卫星网络的处理性能,满足用户通信需求。
英文摘要:
      Aimed at the problems that current research on the static deployment of software defined satellite network controllers is ignorence of the dynamic topology of satellite networks, and the user data traffic is unsteadly,a multi controller dynamic deployment method based on the modified whale optimization algorithm (MWOA) is proposed in comprehensive utilization of the dynamic characteristics of satellite networks by setting three threshold values and adopting switch migration in combination of the software defined satellite network architecture. The simulation results show that compared with other algorithms, MWOA has significant advantages of switching migration costs, controlling link delay, and load balancing. This method can further improve the processing performance of satellite networks and meet the needs of communication for users.
