摘要

针对卫星高速移动导致的卫星网络内部及与地面网络间的连接关系不断变化的问题，提出了一种基于位置的天地一体化网络路由寻址机制——LA-ISTN。用户的IP地址携带其地理位置信息，在星间路由时，基于位置信息计算得到的路由方位选择最优的转发接口。仿真结果表明，相对于快照协议和OSPF路由协议，LA-ISTN显著降低了星上路由表存储开销，没有路由更新包交换开销和邻居通信开销；星上路由不依赖预测的链路连接关系，稳健性强，可保证网络时刻可用。

Abstract

The ever-changing characteristics of the connection between the satellite network and the terrestrial network caused by the high-speed movement of the satellites have always been one of the most important problem that plagues the routing mechanism of the satellite network and integrated network.To address this problem

a location addressing based routing mechanism of integrated satellite and terrestrial network (LA-ISTN) was proposed.LA-ISTN exploited the user’s physical location in the user’s IP address to calculate the routing orientation.Based on the orientation

LA-ISTN could choose the best forward interface.Theoretical analysis and simulation experiments show that compared with snapshot protocol and OSPF routing protocol

LA-ISTN significantly reduces the route table storage overhead

with no routing updates cost caused by neighbor packet switching and communication.Inter-satellite route selection is not dependent on the prediction of link connection relations

with strong robustness

can always guarantee the network’s availability.
