摘要
随着航天技术、电子技术以及通信技术的发展,空间网络由于其"高、广、远"的独特优势,在对地观测、应急通信、航天测控、航空运输等方面都有着重要的作用。然而,空间网络面临星上处理能力受限、传输延时差异大等方面的挑战。为在空间网络中满足不同业务的差异化服务质量(QoS)需求,对面向空间网络的虚拟路由器实现方法进行了研究。在分析了国内外在虚拟路由器领域的探索与实践情况的基础上,针对空间路由设备对载荷和功耗的要求,提出了一种面基于ZYNQ嵌入式平台和轻量级虚拟化技术LXC(Linux Container)的虚拟路由器实现方法。实验表明,提出的虚拟路由器实现方法可以在处理能力受限的嵌入式平台上实现差异化的服务。
With the development of aerospace technology,electronic technology and communication technology,space network plays an important role in earth observation,emergency communication,space tracking and control,air transportation and other aspects due to its unique advantages of"high,wide and far". However,the space network is faced with challenges such as limited on-board processing capacity and large difference in transmission latency. In order to meet the differentiated quality of service requirements of different services in space network,this paper studied the implementation method of virtual router for space network. Based on the analysis of the exploration and practice in the field of virtual router at domestic and overseas,a virtual router implementation method based on ZYNQ embedded platform and lightweight virtualization technology Linux Container( LXC) is proposed according to the load and power requirements of spatial routing devices. Experiments show that the virtual router implementation method proposed in this paper can achieve differentiated services on the embedded platform with limited processing capacity.
