摘要：

卫星网络发展到今天，技术日益成熟、国际标准逐渐完善、市场蓬勃发展，但当前卫星网络的高延时弯管架构、不具备标准的星上IP功能以及缺乏兼容性与扩展性等局限性，导致其不能像地面Internet一样高速而迅猛地发展。下一代卫星网络只有利用成熟的IP 技术组建IP 卫星网络和地面Internet无缝对接，才能突破卫星网络发展的瓶颈，满足用户廉价和方便的服务需求。本文在总结当前卫星网络局限性的基础上，探讨了下一代卫星网络IP 化的必然性、架构及优势，并阐述了下一代卫星网络面临的挑战及机遇。

Abstract:

The satellite network has being developed to today, its techniques have being developed maturely, international standards have being gradually developed, and markets also have being boomed. But the limitations in recent satellite networks, which are high-latency pipe structure, non-standard satellite IP function, lack of compatibility and expansibility, and so on, block the rapid development of them comparing with the ground Internet. Only when next generation satellite networks utilize mature IP technology to build IP satellite network and seamlessly connect with internet on the earth, we can break through the developmental bottleneck of satellite network and meet cheap and convenient service of the users. Based on summarizing limitations of the present satellite network, we have explored the necessity, structure and advantages of next generation satellite network, and have elaborated challenges and opportunities faced by next generation satellite network.

Key words: next generation satellite network, IP technology, challenge, opportunity
