ICN-WEN: Collaborative Research: Light-Speed Networking (LSN): Refactoring the Wireless Network Stack to Dramatically Reduce Information Response Time

下一代移动和无线应用(如自动驾驶汽车安全、触觉互联网、虚拟/增强现实、工业机器人和远程手术)的一个关键障碍是超低信息响应时间(IRT)，因为这些应用在用户感知的体验方面持续显著改善，一直到低至一毫秒的IRT。不幸的是，尽管新兴的无线通信标准有相当雄心勃勃的计划，但今天的互联网协议栈不能在无线环境中实现1毫秒的常见IRT。降低IRT的一个基本瓶颈是传输延迟受到光速的限制，以及协议堆栈中的各种因素。该项目正在研究“光速网络”(LSN)体系结构的设计、实施和评估，该体系结构寻求通过在网络协议栈的不同层整体地整合以信息为中心的方法来显著降低无线边缘网络中的IRT。该项目还将开发新的课程和宣传材料，旨在对新一代劳动力进行信息感知网络原理的教育，这些原理将成为未来通信网络的基础。LSN项目将使网络能够自动将靠近最终用户的远程服务端点迁移到虚拟基站上的纳米云上，从而减少受光速限制的传播延迟。LSN将这一能力与其他几个新想法结合在一起，包括信息价值感知：使不同的层能够利用关于数据价值和语义的应用级知识；私人信息检索：使用户能够访问信息，而不向网络透露他们正在访问什么；无线电多态：能够根据信息价值智能地使用不同的无线电；以接入点为中心的安全和隐私增强；等等。LSN建立在最近的下一代互联网体系结构项目(包括MobilityFirst和XIA)的关键思想基础上。

A key hurdle for next-generation mobile and wireless applications such as autonomous vehicle safety, tactile Internet, virtual/augmented reality, industrial robotics, and tele-surgery is ultra-low information response time (IRT), since these applications continue to see significant improvement in user-perceived experience all the way down to an IRT as low as a millisecond. Unfortunately, today's Internet protocol stack, despite the rather ambitious projections of emerging wireless communications standards, is unable to achieve a 1 millisecond common-case IRT in wireless environments. A fundamental bottleneck for reducing IRT is propagation delays limited by the speed of light as well as a variety of factors across the protocol stack. This project is investigating the design, implementation, and evaluation of a "light-speed networking" (LSN) architecture seeking to dramatically reduce IRT in wireless edge networks by incorporating an information-centric approach holistically across the different layers of the network protocol stack. This project will also develop novel curricula and dissemination materials aimed at education of a new generation of workforce in information-aware networking principles that are going to be the foundation of future communication networks.The LSN project will enable the network to automatically migrate a remote service endpoint close to the end-user, for example, onto a nano-cloud on a virtualized base station, thereby cutting down propagation delays limited by the speed of light. LSN combines this capability with several other novel ideas including information-value-awareness: enabling different layers to leverage application-level knowledge about the value and semantics of the data; private information retrieval: enabling users to access information without revealing to the network what they are accessing; radio polymorphism: enabling intelligent use of different radios based on information value; access-point-centric security and privacy enhancements; etc. LSN builds upon key ideas from recent next-generation Internet architecture projects including MobilityFirst and XIA.
