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体验方面不断取得显著改善，IRT一直低至1毫秒。不幸的是，尽管新兴的无线通信标准有相当雄心勃勃的预测，但今天的互联网协议栈无法在无线环境中实现1毫秒的通用IRT。减少IRT的一个基本瓶颈是受光速以及协议栈中的各种因素限制的传播延迟。该项目旨在研究“光速网络”（LSN）架构的设计、实现和评估，通过在网络协议栈的不同层中整合以信息为中心的方法，大幅减少无线边缘网络中的IRT。这个项目还将编制新的课程和传播材料，目的是教育新一代工作人员了解信息联网原则，这些原则将成为未来通信网络的基础。LSN项目将使网络能够自动迁移靠近最终用户的远程服务端点，例如，迁移到虚拟基站上的纳米云，从而减少受光速限制的传播延迟。LSN将这种能力与其他一些新颖的思想结合起来，包括信息-价值感知：使不同的层能够利用有关数据的价值和语义的应用级知识；私有信息检索：允许用户访问信息而不向网络透露他们正在访问的内容；无线电多态：基于信息价值实现不同无线电的智能使用；以接入点为中心的安全性和隐私增强；等。LSN建立在最近的下一代互联网架构项目（包括MobilityFirst和XIA）的关键思想之上。

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.
