Architecture Design and Key Technologies Analysis of LEO Satellite Mega-Constellations
Published 2024-06-01“…The large number of network elements in the mega-constellations pose a severe challenge to the existing network architecture and technical system.Based on the concept and characteristics of constellation architecture, combined with the development of domestic and foreign satellite constellations and technology prediction, a multi-layer and multi-domain hybrid intelligent cooperative network architecture was proposed, which consist of four layers (perception plane, data plane, control plane, intelligent management plane) and three layers (resource layer, transport layer, service layer) , the architecture of constellation network management and control, technology reference model and protocol architecture were designed.At the same time, accorded to the construction and development trend of constellation, this paper expounded and analyzed the evolution trend of the key technologies, such as constellation network addressing and routing, network robust agile guarantee, differentiated service bearing, end-to-end reliable transmission, etc.The research results could support the development and construction of LEO giant constellation network in our country.…”

Research on Strategies and Technologies for Resource Management and Control of Heterogeneous Network of High and Low Orbit Satellites
Published 2021-12-01“…With the vigorous development of space communication technology and the continuous advancement of space-integrated-ground information network, satellite communication networks resource management and control is becoming more and more complex.Due to the scarcity of satellite resources, the slowness of resource scheduling compared to the status refreshing, and uneven distribution of business, eff ciently managing resources has become one of urgent problems to be solved in the development of satellite communications.In view of the heterogeneous network system architecture of high and low orbit satellites, the challenges, its network resource management and control facing, were analyzed.Integrating on the basis of traditional management and control architecture, the collaborative management and control architecture based on group management was introduced.The management strategy of satellite network virtual resource pool was explained to relieved resources scarcity.Resource scheduling algorithms based on deep reinforcement learning(DRL) was introduced to solved the mismatch problem of traditional scheduling methods in complex environments.Beam-hopping technology was adopted to deal with the two-dimensional unevenness of service distribution in time and space.…”
