网络技术走演进与革命融合路线

1、网络技术走演进与革命融合路线1969年，美国国防部资助建立arpanet，分为民用和军用两个部分，其中，民用部分于1989年更名为internet互联网。经过将近50年的发展，现在它已经成为与人们日常生活息息相关的重要因素之一。 随着网络通信技术的发展，三网融合、物联网、云计算服务等新技术的兴起对现有网络的扩展性、移动性、安全性、能耗、服务质量等方面提出巨大挑战。探索适合未来互联网应用创新的关键技术迫在眉睫。 任何地点任何终端都流畅 为占领未来网络制高点，美国、日本、欧盟等国家和地区高度重视网络科研基础试验设施的研究与建设，先后启动plantlab、geni、onelab、corelab等一系

2、列基础试验网络建设项目。近日我国首个未来网络小规模试验设施开通仪式在南京未来网络谷召开，标志国内首个未来网络小规模试验设施正式开通。据中国工程院院士、中国科学院计算技术研究所所长李国杰介绍，这是一个试验平台，是国家未来网络创新平台（ceni）的基础。 中国科学院计算机网络信息中心首席科学家钱华林表示，目前未来网络的形态尚不明确，但可以肯定的是，未来网络的速度更快，允许人们在任何地方使用任何终端设备流畅地观看视频。中国工程院院士刘韵洁给记者说出他对未来网络的理解：“所谓未来网络，是指不受现有网络架构模式的约束，高效、多规模、高度可伸缩、灵活可扩展、支持异构融合的新型网络体系结构。” 对于未来网络

3、发展的技术路线，业内有两种说法：一是演进型技术路线，即对原有ip网络架构进行修补，以及利用ipv6解决地址空间的问题；二是革命型技术路线，即彻底脱离原有架构来构建全新的网络体系结构。在刘韵洁看来，未来网络技术应该走演进与革命相融合的技术路线。 7个核心节点 面对全球未来信息网络技术发展的大趋势，加强未来网络基础设施研究与建设势在必行。六年磨一剑，在以刘韵洁、李国杰为代表的团队的努力下，未来网络小规模试验设施得以揭开神秘面纱。据了解，该设施覆盖南京、北京、西安、重庆等4个城市，包括南京未来网络谷、翠屏研发中心、中国科学院计算技术研究所、北京邮电大学、中国联通研究院、西安交通大学、重庆邮电大学7个

4、核心节点。 网络管控中心设在南京未来网络谷，通过联邦机制实现与美国geni与欧盟onelab的互联。设施包括软件可定义虚拟路由交换、数据存储与计算、网络测量与测试、网络资源管控等子系统。单台物理骨干节点可以支持128个异构的虚拟节点并行运行，通过不同层次的编程接口方便用户实现网络数据平面与控制平面分离，并同时实现软件可定义。基于该试验设施，研发团队展示了网络安全云服务、信息安全云服务、网络资源优化、网络加速、面向服务的新型网络体系结构等验证实验，充分体现了该试验设施的虚拟化与可编程能力，灵活支持网络体系结构与业务创新验证。qcwa3ptgz7r4i30ka1dkaghn3xtkknbycudx
