摘要
为了更好地发挥地月空间基础设施对各类用户的服务效能、构建跨域融合一体的地月空间网络,提出了地月云网概念,各星座/设施之间及其内部通过无线链路连接成网,并通过一体化网络协议实现地月空间组网.地月空间组网运行将对传统深空探测任务带来颠覆性变革,可以实现全时段测控、高效数据回传、器间任务协同等.然而,地月云网具有高动态、大时延、强异构特点,这给地月空间组网带来了挑战.对地月空间网络发展与特点进行了分析,构建了适应地月空间特征及满足未来深空探测网络节点互联需求的地月云网协议栈,具有一体化、通用化、分层化、智能化、国际化的特点,并对其数据面和控制面设计进行了阐述.同时对未来地月云网协议发展进行了展望,提出了关键技术.
Abstract
To enhance the service efficiency of cislunar-spatial infrastructure for diverse users and to establish a cross-domain,integrated cislunar-spatial network,the concept of cislunar cloud network is introduced.Interconnecting various constellations and facilities through wireless links,the cislunar cloud network employed the integrated network protocols to facilitate cislunar-spatial networking.The operational deployment of the cislunar-spatial network promised a transformative change for traditional deep-space exploration missions,enabling continuous telemetry,efficient data transmission,and collaborative inter-probe tasks.However,the cislunar cloud network,characterized by high dynamics,significant latency,and strong heterogeneity,poses challenges to cislunar-spatial networking.The development and features of cislunar-spatial networks are analyzed,a cislunar cloud network protocol stack is constructed adaptable to cislunar-spatial characteristics and meeting the interconnection needs of future deep-space exploration network nodes.The protocol stack is characterized by integration,universality,layering,intelligence,and internationalization.The design of its data plane and control plane is elaborated on.Additionally,a forward-looking perspective is provided on the future development of the cislunar cloud network protocols.
