摘要

卫星网络层与空基网络层作为下一代网络的重要组成部分将引领世界进入全球互联时代。然而，飞机作为空基网络的主要节点具有的高机动性和稀疏分布等特点限制了原本为地面自组织网络设计的传统路由算法的应用。利用空基网络接入软件定义卫星网络，通过卫星对飞机的连接实现航空网络中飞机的实时通信与状态同步。为了将航空组网和传输机制扩展到全球范围，提出通过全球范围内划分为多域方法并设计提出一种域间路由算法。该算法通过类比光的反射原理，限制路由学习包传播，高效避免多节点大规模网络场景中状态同步与泛洪学习所带来的巨额通信开销。采用真实的飞机数据进行实验仿真，验证了相较其余基准算法，设计的低代价域间路由算法可以有效地降低通信成本和提高传输质量。

Abstract

Satellite network layer and aeronautical network layer are treated as important parts of the next generation network

which will lead the world into the era of global interconnection.However

the high mobility and sparse distribution of aircraft limit the application of traditional routing algorithms originally designed for ground-based ad-hoc networks.Therefore

this paper used the aeronautical network to access software defi ned satellite network (Sat-SDN) for realizing real-time communication and state synchronization between aircraft via the inter-satellite and satellite-to-aircraft links.In order to extend the aeronautical networking and transmission mechanism to the global scope

a multiple domain division method was proposed

and an inter domain routing algorithm was presented.By analogy the refl ection principle of light

a routing learning method which limited the broadcasting of routing learning packets into a specifi c area was proposed

and eff ectively avoided severe communication overhead caused by state synchronization and fl ooding learning in large-scale networks.The real aircraft data was used for experimental simulation to compared the performance of proposed low-cost inter-domain routing algorithm (LIRA) with existing solutions.The simulation results showed that LIRA could eff ectively reduced the communication overhead and improved the transmission quality.
