摘要: 為了克服空天地一體化網(wǎng)絡(luò)系統(tǒng)(Space-Air-Ground Integrated Network,SAGIN)由于結(jié)構(gòu)復(fù)雜和業(yè)務(wù)多樣而導(dǎo)致的不同網(wǎng)絡(luò)間的協(xié)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(gòu)。通過將網(wǎng)絡(luò)系統(tǒng)劃分為數(shù)據(jù)層、控制層和管理層,網(wǎng)絡(luò)狀態(tài)信息由各網(wǎng)絡(luò)層逐層匯總和分層處理,網(wǎng)絡(luò)管理策略由MEC統(tǒng)一制定,并逐層轉(zhuǎn)發(fā),實現(xiàn)不同網(wǎng)絡(luò)間的協(xié)同管理。基于所提架構(gòu)搭建網(wǎng)絡(luò)仿真平臺,并通過強化學(xué)習(xí)方法制定網(wǎng)絡(luò)協(xié)同策略,仿真結(jié)果證明了該架構(gòu)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.
Key words : SAGIN;network architecture;network management;MEC
