摘要: 為了克服空天地一體化網絡系統(Space-Air-Ground Integrated Network,SAGIN)由于結構復雜和業務多樣而導致的不同網絡間的協同困難,提出了基于移動邊緣計算(Mobile Edge Computing,MEC)的SAGIN多維管理架構。通過將網絡系統劃分為數據層、控制層和管理層,網絡狀態信息由各網絡層逐層匯總和分層處理,網絡管理策略由MEC統一制定,并逐層轉發,實現不同網絡間的協同管理。基于所提架構搭建網絡仿真平臺,并通過強化學習方法制定網絡協同策略,仿真結果證明了該架構的可行性。

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.
