Abstract Satellite networks have high requirements for security and data processing
speed. In order to improve the reliability of the network, software-defined network (SDN)
technology is introduced and a central controller is set in the network. Due to the
characteristics of global perspective, control data separation, and centralized control of
SDN, the idea of SDN is introduced to the design of the satellite network model. As a
result, satellite nodes are only responsible for data transmission, while the maintenance of
the links and the calculation of routes are implemented by the controller. For the massive
LEO satellite network based on SDN,… More >
