摘要
随着科学技术的发展,卫星网络在通信技术方面发挥的作用越来越重要,卫星网络组网关键技术的研究越来越受到学术界与工业界的重点关注。从卫星网络研究的背景与意义出发,比较了卫星网络包括同步卫星网络与低轨卫星网络的优缺点,详细介绍了几种典型的低轨卫星星座网络,分别从卫星切换、路由、卫星网络虚拟化三个方面分析了卫星网络组网的研究现状、存在问题与发展趋势,最后,对卫星网络组网关键技术的研究进行总结与展望。
With the rapid development of science and technology,satellite network is playing an increasingly important role in communications technology.The key issue of satellite network is paid more and more attention by academia and industry.In this paper,the background and significance of satellite network are given.And then,the advantages and disadvantages of satellite network including synchronous satellite network and low earth orbit satellite network are compared.What's more,we introduce several typical Low Earth Orbit(LEO)satellite constellation network and analyze the satellite handover,routing,virtualization of satellite network in three aspects:the research situation,issues and development trend.Finally,we conclude the key issues of satellite network.
