摘要
根据目前天地一体化网络发展趋势,提出作为天基骨干网的卫星通信港架构,针对卫星通信港的组网问题,设计一种适用于天地一体化的卫星通信港架构方案。该方案基于SDN的集中式管理模型,通过多域控制器连接管理由天基接入网和地基接入网组成的多个控制域,每个控制域均部署单域控制器进行域内管理。通过STK软件对方案进行仿真。仿真结果表明,卫星通信港在网络覆盖和灵活组网特性上更具优势,符合我国天地一体化网络发展的需求。
According to the current trend of integration of space and ground networks,an architecture for satellite communication formation used as space-based backbone network is proposed.In view of the networking problem of satellite communication,a scheme of satellite communication formation is designed for integration of space and ground networks.Based on SDN centralized management model,this scheme manages multiple control domains composed of space-based access network and ground access network through multi-domain controller connection.Each control domain is deployed in domain management.The program is simulated through STK software.The results show that the satellite communication formation features more advantages in network coverage and networking flexibility,and meets China＇s space communication needs of the integration of the ground network.
