Embodiment Construction
[0020] refer to figure 1 . In the embodiments described below, a spatial information network service architecture is composed of a backbone network, an access network, various functional subnets, and a single application terminal node. Various existing systems can communicate with this system through a gateway connect. The spatial information network is mainly composed of backbone network, access network and functional subnet. Among them, the backbone network is the core of the space information network, which is responsible for the comprehensive management and control of space resources and networks; the state perception of space resources and the transmission, processing and distribution of command and control information for space resources; assisting in the transmission, processing and distribution of important sea, land and air users Terminal information. The access network is composed of access devices, access nodes and access links, and realizes functions such as ran...

The invention provides a space information network service system structure, and aims at providing a service system structure which is clear in work division, good in comprehensiveness and high in transmission efficiency. The space information network service system structure is achieved through the following technical scheme that a backbone link and an access link achieve heterogeneous network protocol conversion by adopting BP transmission, routing and gateway protocols of a delay tolerant network (DTN)-based layered protocol system to build a space information network protocol system; traffic control is conducted by means of a base pointer, an instruction pointer (IP) and multiple virtual channel layers according to the node types and the link types, a space information network functionmodel is built from two dimensions of service-oriented functions and system-oriented functions, and a backbone network comprehensively controls space resources of the network, senses and transmits the states of the space resources, processes and allocates command control information of the space resources and assists in transmitting, processing and allocating information of sea-land-air user terminals; and an access network achieves random access and information transmission of various user terminals or function subnetwork gateways.
Description
technical field [0001] The invention relates to the field of space network communication for earth observation, satellite navigation, and deep space exploration. It can provide a unified platform for the acquisition, storage and distribution of space information, and can realize the unified management, efficient sharing and comprehensive utilization of space information network. Spatial information network service architecture of large space-time span network architecture. Background technique [0002] The space information network can acquire, transmit and process massive amounts of information generated by space platforms deployed in different space locations and performing different tasks in real time, such as various satellites, near-space vehicles, aircraft, etc., and corresponding ground facilities. The ability of data transmission can effectively realize the connection of land, sea, air, space, and ground multi-dimensional information systems. The space information t...
