This project introduces a grand challenge for the networking community and industry: reducing Internet latencies to close to the limiting physical constraint, the speed of light in free space. Achieving this vision of a 'speed-of-light Internet' could translate into significant value for today's applications; for example, shaving even a few hundred milliseconds from a Web transaction may translate into millions of dollars of revenue for a Web provider, or significantly impact emergency or defense response. The human visual system cannot correctly order visual events separated by less than about 30 millisecond; thus, a response received over the Internet within thirty milliseconds would achieve the illusion of an "instant response", potentially enabling the full potential of certain applications, e.g., tele-immersion, that have so far been limited to the laboratory. For some applications, such as massive multi-player online games, (or any online interactive community), reducing the latency of the Internet will push applications to reach a critical mass of users. A speed-of-light Internet can also be expected to spur the development of new and creative applications. This proposal aims at developing a playbook for realizing a speed-of-light Internet, by identifying the factors that contribute to latency, the applications that would benefit most, and developing an architecture, protocols and methodologies for achieving it.The four main goals of this project are to (1) determine the impact of latency on end users, (2) design a speed-of-light Internet, (3) explore "end-point agnostic" mechanisms for reducing latency, and (4) determine how to operate, maintain, and make use of a bandwidth-constrained low-latency network. The project will investigate these questions in the context of candidate applications including electronic commerce, games, and virtual and augmented reality. The proposed work includes new algorithms and design for the wide-area network infrastructure, and new protocols and network management to deal with the dynamic partitioning of application traffic across the two infrastructures. The project will explore how to leverage low-latency networking technologies, i.e., microwave and millimeter wave radios, which have thus far been deployed as point-to-point links over long distances primarily for the financial industry; specifically, how they can be incorporated into the Internet at large. The work will be carried out in collaboration with McKay Brothers, the operators of an ultra-low-latency network linking financial markets in New York and Chicago, Akamai Technologies, a major provider of content delivery services, and Exablaze, a manufacturer of the ultra-low-latency network interface cards. This will inform the design of a cSpeed mesh network, and its interaction and interoperability with the standard Internet.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目为网络社区和行业带来了一个巨大的挑战：减少互联网潜伏期，以接近限制的物理约束，即自由空间中的光速。实现“光速互联网”的这种愿景可以转化为当今应用程序的重要价值；例如，从网络交易中剃掉几百毫秒的人可能会转化为网络提供商数百万美元的收入，或显着影响紧急情况或国防响应。人类视觉系统无法正确订购少于30毫秒的视觉事件；因此，在三十毫秒内通过互联网收到的响应将实现“即时响应”的幻想，从而有可能使某些应用的全部潜力，例如，迄今为止，这些应用程序已限于实验室。 对于某些应用程序，例如大量的多玩家在线游戏（或任何在线互动社区），降低互联网的延迟将推动应用程序吸引大量用户。也可以预期，光速互联网刺激了新的和创意应用程序的开发。该建议旨在通过确定有助于潜伏期的因素，将受益最大的应用程序以及开发实现它的架构，协议和方法来开发一本剧本来实现光速的互联网。该项目的四个主要目标是（1）确定延迟对用户的影响，（2）设计速度的互联网，（3）探索速度的机制，（2）探索速度的机制。 （4）确定如何操作，维护和利用带宽受限的低延迟网络。该项目将在候选应用程序的背景下调查这些问题，包括电子商务，游戏以及虚拟和增强现实。 拟议的工作包括针对广域网络基础架构的新算法和设计，以及新的协议和网络管理，以处理两种基础架构的应用程序流量的动态分区。 该项目将探讨如何利用低延迟网络技术，即微波炉和毫米波收音机，到目前为止，这些技术主要是为金融业而部署的长距离链接；具体来说，如何将它们整合到整个互联网中。这项工作将与麦凯兄弟（McKay Brothers）合作，麦凯兄弟（McKay Brothers）是一个超级延迟网络的运营商，将纽约和芝加哥的金融市场联系在一起，秋田技术公司（Akamai Technologies），内容交付服务的主要提供商，以及超低网络网络接口卡的制造商Exablaze。这将为CSPEED网络网络的设计及其与标准互联网的互动和互操作性提供信息。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为是值得通过评估的。
