CAREER: Putting Network Measurements to Work - Design & Evaluation of Measurement-Driven Network Mechanisms

该项目的中心论点是，互联网测量领域已经成熟到可以从描述性角色转变为操作性角色。在终端主机、路由器或边缘设备和代理处被动或主动收集的测量结果可以反馈并用于应用程序、传输协议、数据包转发引擎和路由机制。该项目旨在设计和评估由测量驱动的重要网络机制。以下是三种这样的机制。主要路由器进程的自动配置技术，例如基于路由器接口中的被动测量的缓冲区管理技术动态路由选择，由主动边缘到边缘性能测量和拥塞预测驱动高带宽长距离网络的传输优化，使用最近开发的带宽估计技术。对测量的关注已融入该项目的研究和教育方面。主要的教育目标是将网络测量作为学习和可视化工具引入课堂。 PI 将创建一门互联网测量研究生课程，也涵盖“网络统计”，即用于分析网络测量的统计工具的集合。该项目可以产生重大的技术、经济和社会影响。将网络测量作为一种操作工具进行大规模部署可以提高互联网的性能、弹性和稳健性，并支持新的服务和应用。正在开发的工具、原型和学习材料均已公开。最后，测量在课程中的整合从根本上改变了计算机网络的教学方式。

The central thesis of this project is that the area of Internet measurements has matured to the point that it can advance from a descriptive to an operational role. Measurements, collected passively or actively at end-hosts, routers, or edge devices and proxies, can be fed back and used in applications, transport protocols, packet forwarding engines, and routing mechanisms. The project aims at the design and evaluation of important network mechanisms driven by measurements. Three such mechanisms are the following. Techniques for the auto-configuration of major router processes, such as buffer management, based on passive measurements in router interfaces Dynamic route selection, driven by active edge-to-edge performance measurements and congestion prediction Transport optimizations for high-bandwidth long-distance networks, using recently developed bandwidth estimation techniques.The focus on measurements is integrated in the project's research and education aspects. A major educational objective is to bring network measurements into the classroom as a learning and visualization tool. The PI is going to create an Internet measurements graduate course, lso covering "network statistics", i.e., a collection of statistical tools for the analysis of network measurements. The project can have a significant technological, economic, and social impact. A wide-scale deployment of network measurements as an operational tool can improve the Internet's performance, resilience, and robustness, and enable new services and applications. The tools, prototypes, and learning material being developed are made publicly available. Finally, the integration of measurements in the curriculum changes radically the way in which computer networking is being taught.
