摘　　要： 相对于互联网上层应用和底层通信技术的蓬勃繁荣,互联网的基本网络架构并没有得到同步发展,还是基于设计之初的TCP/IP协议.随着应用环境、用户需求和底层设施的不断发展变化,现有的网络结构已暴露出越来越多的缺陷.针对这些问题,研究人员提出了许多新的网络架构、概念、服务、协议和算法,以构建不同于现有互联网的新型未来互联网.不过,任何一种新的思想在实现或部署到真实的网络之前,都必须经过严格的测试和验证.因此,构建大规模的、真实的、可控的试验平台不仅是未来互联网研究的基础,也是对未来互联网本身探索和研究的一种途径.文中从规模、功能、开放性等基本特性以及科学实验要素、网络元素类型三个方面对试验平台进行了归纳和分类;分析了试验平台的结构化原则和分层结构;重点分析和总结了构建试验平台的关键技术,包括实验描述语言、控制框架和网络资源分片技术;分析了国内试验平台的发展现状;最后探讨了未来互联网试验平台的发展趋势. Abstract Comparing to the booming prosperity of the Internet application and the underlying communication technology, the basic network architecture of the Internet has not been developed simultaneously, and is based on the beginning design of TCP/IP protocol. With the evolvement of application environment, user requirements and underlying facilities, the existing network architecture has exposed more and more defects. For these problems, researchers have proposed many new network architecture, concepts, services, protocols, and algorithms to build the new Future Internet, which is different from the existing Internet. However, any of such new ideas must be tested and evaluated rigorously before being realized or deployed in the actual Internet. So it is not only the base of Future Internet research, but also the way to explore the Future Internet itself to build the large-scale, realistic, controlled experiment platform. This paper concludes and categorizes the experiment platform from the basic characteristics of scale, function, openness, science experimentation elements, and network element type. The architecture princi- ple and hierarchical framework are analyzed. Apart from that, the key technologies to build Future Internet, resource slicing, including the experiment description language, control framework and network are analyzed mainly. After that, the status of domestic experiment platform is analyzed. Finally, the development trend of Future Internet experiment platform is discussed.
