摘要: 为了克服空天地一体化网络系统(Space-Air-Ground Integrated Network,SAGIN)由于结构复杂和业务多样而导致的不同网络间的协同困难,提出了基于移动边缘计算(Mobile Edge Computing,MEC)的SAGIN多维管理架构。通过将网络系统划分为数据层、控制层和管理层,网络状态信息由各网络层逐层汇总和分层处理,网络管理策略由MEC统一制定,并逐层转发,实现不同网络间的协同管理。基于所提架构搭建网络仿真平台,并通过强化学习方法制定网络协同策略,仿真结果证明了该架构的可行性。

Abstract: In order to overcome the difficulties of cooperation between different networks caused by the complex structure and diverse services of SAGIN(Space-Air-Ground Integrated Network), a multi-dimensional management architecture of SAGIN based on Mobile Edge Computing(MEC) is proposed. The network system is divided into data layer, control layer and management layer. The network state information is collected and processed layer by layer and the network management strategy is formulated by MEC and forwarded layer by layer. The simulation platform based on the proposed architecture is built, and the network cooperation strategy is formulated through reinforcement learning method. The simulation results prove the effectiveness of the proposed architecture.
