【摘要】 近年来,基于互联网的应用发展迅速,导致IP业务已成为通信网络所承载的主要业务。采用IP技术,便于星座网络与地面网络更好地融合,因此星座IP路由已成为目前的研究热点。根据网络服务策略的不同,本文对面向连接和无连接的ISL路由技术进行了介绍, 并分析比较了各种路由技术的优缺点。作为一种新的尝试,借鉴移动自组织网的路由思想设计星座路由的方法在本文中也做了简要探讨。更多还原

【Abstract】 The growth of Internet-based applications in recent years has led to telecommunication system transporting an increasing large amount of IP-based traffic. IP technologies would be desirable for merging constellation network and terrestrial network, so IP routing has become a hot topic in the research area of satellite constellation network. Based on the difference of service strategy, there are two types of routing strategy: connection-oriented and connectionless-oriented ISL routing. After the introduction of major routing algorithms, we analyzed their advantages and disadvantages. MANET routing, which is also discussed briefly, .is a new method of resolving constellation routing problem.更多还原
