Abstract. In the conventional satellite communication networking process, face with many problems, such as resource utilization is not high, QoS is weak, lack of real-time dynamic adjustment to link. PCC architecture-based satellite communications network model through a secure channel to receive channel real-time monitoring information, enhance the satellite resources utilization and QoS based on the policy mechanism, and improve the user experience. On the basis of given networking process, the function units is described in detail, which lays the foundation for the next step of the simulation.
