2005年1月,美国的30位互联网专家组织了“跨越网络革命性创新的障碍”研讨会,这个研讨会是由TomAnderson、LarryPeterson、ScottShenker以及JonathanTumer等人发起的,会议向NS(F美国自然科学基金会)提交了相关的报告。在这个研讨会报告的基础上,一个美国网络研究领域重构下一代互联网的计划——GENI项目逐渐成形。2005年8月底,NSF专家在费城的科学讨论会上首次公开讨论了这一项目,目标是创建一个新的互联网和分布式系统架构,其设想超出了目前渐进式改进Internet的努力范围,预计将耗资3亿美金,为期10年。目前,该项目仍处于规划阶段,3亿美元的投入预算还处于评估之中。GENI于2006年2月从原有的“GlobalEnvi-ronmentforNetworkingInvestegations(”全球网络探索环境)更名为“GlobalEn-vironmentforNetworkInnovations(”全球网络创新环境),这一更名体现了其革命性的主旨。本刊将分三期对“跨越网络革命性创新的障碍”研讨会报告进行全文译介,奉献给关注并正在进行互联网研究的工作者们。这个报告共有五个部分,第一部分是关于重构下一代互联网的总体建议,提出全新的革命性设想;第二部分阐述Internet在发展中出现的各种问题,以及目前为此而进行的一些渐进式的修正努力;第三部分提出了目前Internet面临的严峻挑战,及迎接挑战的方案,包括安全、经济动机、地址绑定、终端主机假设、用户层的路由选择、控制和管理、满足应用的需求等七大方面,这是网络体系结构上七个可能的局限性,指出新网络要减少信用猜忌、给用户选择权、允许边界差异、让网络透明、符合应用的需求等;第四部分是Internet体系结构创新的试验性部署,提出建立一个全球访问和不同性能的试验床,这一部分勾勒了搭建这个试验床的目标和设计原理;第五部分是对创建全新网络的六大建议,建议NSF采取新的措施,以便在互联网领域推进创新性变革,从而释放出受限于目前Internet服务的新的应用类型。
In January 2005, 30 Internet experts from the United States organized a Symposium on “Barriers to Crossing the Web for Revolutionary Innovation,” sponsored by Tom Anderson, Larry Peterson, Scott Shenker, and Jonathan Tumer, Foundation) submitted the relevant report. On the basis of this workshop report, a plan for the reconstruction of the next generation of Internet in the field of network research in the United States - the GENI project is gradually taking shape. At the end of August 2005, NSF experts debuted this project for the first time at a scientific symposium in Philadelphia with the goal of creating a new Internet and distributed system architecture that was beyond the current efforts to improve the Internet so far. Cost 300 million US dollars for a period of 10 years. At present, the project is still in the planning stage and the estimated investment of 300 million U.S. dollars is still under evaluation. GENI changed its name to GlobalEnvironment for NetworkInnovations (“Global Network Innovation Environment”) in February 2006 from its original GlobalEnvivision for NetworkingInvestegations (“Global Network Discovery Environment”), a change of name that reflects its revolutionary thrust. This issue will be translated in three phases on the report of the Symposium on “Barriers to Innovation Across the Web,” dedicated to those concerned and conducting Internet research. The report consists of five parts. The first part is about the overall proposal for the reconstruction of the next generation of Internet and proposes a completely new and revolutionary vision. The second part describes various issues arising in the development of the Internet and some progress made so far The third part presents the current Internet challenges and challenges to meet the challenges of the program, including security, economic motivation, address binding, end-host hypothesis, user-level routing, control and management, to meet the application Demand and other seven aspects, which is the network architecture of the seven possible limitations, pointed out that the new network to reduce the risk of suspicion, to the user to choose the right to allow the border difference, so that the network is transparent, in line with the needs of the application; the fourth part is The tentative deployment of an Internet architecture innovation proposes the establishment of a global access and test bed of varying performance that outlines the objectives and design principles for building this test bed. The fifth section is the six recommendations for creating a new network, recommending NSF Take new steps to promote innovative change in the Internet space, freeing up the Internet New types of business applications.
