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.
