Research On Architecture Of Space Information Transmission Network

In step with the prompt development of aerospace technology, building earth-space integrated space information network is an effective way, as well as a development orientation to utilize space and improve the overall application capacity of information system. Based on the important role and main characteristics of information transmission in space information network, the two-layer architecture conception of space information transmission network(SITN) including the "backbone layer and regional access layer" is presented. Taking the networked management and application service of SITN as the object, the system components of the backbone layer are investigated, and a "management and data transmission" dual-network functional configuration of backbone network is designed, providing technology reference for accelerating the development of SITN.
