地月云网:跨域融合一体的地月空间网络OA北大核心CSTPCD

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.
