摘要
在中低轨道卫星星座中,利用星间链路组网是宽带卫星网络技术发展的一个主要方向。卫星网络中的边界路由主要解决卫星网络和地面网络之间在网络层的互操作性问题,实现网络层的互相融合,使端用户能够通过异构网络来透明地通信。在分析已有研究的基础上,结合地面网络使用的边界路由技术,给出了地面网络与卫星网络的互连模型,分析了具有星间链路的卫星网络中边界路由问题的实质,并介绍了一种基于BGP-4协议的卫星网络边界路由机制,进而指出了后续的研究方向。
Building networks with Inter-Satellite Links （ISLs） in MEO/LEO satellite constellation is becoming a major trend of broadband satellite networks. The main task of border routing in satellite networks is to resolve interoperation problem in network layer between satellite networks and terrestrial networks, and so to achieve network layer integration and make the end users feel they can communicate with each other just like in one type of networks. By introducing related work in this area and border routing technique used in terrestrial network, the inter-connection model of satellite/terrestrial networks is presented in the paper, and the essential of border routing in satellite network with ISis is analyzed, then a satellite network border routing scheme based on BGP-4 is introduced. Finally, the last section concludes the paper and identifies some future research directions.
