摘要

由于空间设备资源扩展能力和物理环境的限制造成天基信息港网络丢包率与时延较高，无法满足高性能信息任务处理需求.本文对对等共享网络的集中式和结构化分布式网络结构模型进行具体研究，共提出了四种天基信息港对等共享网络模型方案.基于PeerSim仿真平台对所提出的结构化分布式对等网络搭建了仿真平台，研究关键参数对网络性能的影响.结果表明，对于节点移动性强的大型卫星网络，天基信息港结构化分布式双层对等网络相较于单层网络不仅时延减少近90%，并能够保证查找成功率达到98%以上.通过仿真验证了我们所提方案的合理性，具备提高天基信息港信息处理能力的优势.

Abstract

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.
