摘要：

Due to the limitation of space equipment resource expansion ability and physical environment, making the packet loss rate and delay high, so the space-based information port cannot meet the requirements of high-performance information task processing. This paper studies the centralized and structured distributed network structure models of P2P (Peer to Peer) sharing network, and puts forward four P2P sharing network model schemes. Based on PeerSim simulation platform, a simulation platform is built for the proposed structured distributed peer-to-peer network, and the influence of key parameters on network performance is studied. The results show that for large satellite networks with strong node mobility, compared with the single layer network, the structured distributes two-layer P2P network of the space-based information port can not only reduce the time delay by nearly 90%, but also ensure that the success rate of the search can reach more than 98%. The simulation results verify the rationality of the proposed scheme, which can improve the information processing ability of the space-based information port. © 2022 Chinese Institute of Electronics.
