[Abstract] The architecture of the space-based transmission network has a substantial impact on the integrated space and terrestrial information network. A two-layered architecture constructed by integrating geostationary orbit (GEO) and low earth orbit (LEO) satellite constellations is proposed for the space-based transmission network, and related issues such as the onboard processing ability, air interface, protocol stack, routing and switching, and systematic verification are discussed.
