卫星网络路由技术∗

摘要

The periodic and dynamic topology of satellite networks poses new challenge to the design of routing protocols. Since the routing protocols of conventional networks can not be effectively applied to satellite networks, many new routing techniques for satellite networks were put forward. With an introduction to satellite network architecture and topology control strategies along with the developmental history of routing techniques on satellite networks, this paper summarizes the core mechanism, feature and major problems of some important routing techniques of satellite networks from the classification perspective. Considering application requirements, the paper also suggests the future trends towards the development of routing techniques on satellite networks.%卫星网络周期性动态变化的拓扑对路由协议的设计提出了新的挑战。由于传统网络的路由协议不再适用于卫星网络，许多针对卫星网络的路由技术被相继提出来。在简要介绍卫星网络架构与拓扑控制策略的基础上，根据卫星网络路由技术的发展脉络，从分类的角度重点阐述了一些关键路由技术的核心机制、特点以及存在的主要问题。最后，针对应用需求，提出了卫星网络路由技术的发展趋势。
