NeTS-NR: A Measurement-Driven Approach to Internet Protocol and Systems Design

提案编号：0435382PI：Bruce Maggs机构：卡内基梅隆大学标题：互联网协议和系统设计的测量驱动方法摘要：当今互联网的巨大规模和复杂性使网络研究人员难以评估协议变化可能对其运行产生的影响。基本问题是很难为测试目的而部署足够广泛的新协议。作为回应，该项目使用了一种新的方法(测量驱动的协议设计)，将互联网的大规模测量与新协议的设计相结合。大规模测量能够对协议行为进行准确的仿真和基于模拟的评估，因此是对许多协议设计进行假设分析的关键。这种衡量到评估的方法使该项目能够在协议和系统设计领域做出重大贡献。该项目开发了这一新的方法，作为许多具体研究的一部分，这些研究结合在一起，推动了标准IP和覆盖路由方面的最先进技术。具体地说，该项目希望做出以下主要贡献：1)广域IP路由的新设计，结合了诊断域间路由问题和域间流量工程的技术；2)通过新的流媒体覆盖设计和反射器网络优化来显著改进覆盖路由；以及3)使用覆盖和IP路由技术的新组合来优化接入网络的性能和可用性。除了开发的方法和协议之外，作为研究的一部分，很大一部分测量结果将用于研究和教育。为了使它们可用，该项目还探索了网络测量的匿名化技术。

Proposal Number: 0435382PI: Bruce MaggsInstitution: Carnegie Mellon University Title: A Measurement-Driven Approach to Internet Protocol and System DesignAbstract: The sheer size and complexity of the Internet today has made it difficult for network researchers to evaluate the impact that protocol changes may have on its operation. The basic problem is that it is difficult to deploy new protocols widely enough for testing purposes. In response, this project uses a novel approach (Measurement-Driven Protocol Design) that combines large-scale measurements of the Internet with the design of new protocols. Large-scale measurements enable accurate emulation- and simulation-based evaluation of protocol behavior and, thus, are the key to doing the "what if" analysis for many protocol designs. This measure-to-evaluate approach enables the project to make significant contributions to the areas of protocol and system design. This project develops this new methodology as part a number of specific research thrusts that, in combination, push the state-of-the-art in both standard IP and overlay routing. Specifically, the project expects to make the following major contributions: 1) novel designs for wide-area IP routing incorporating techniques for diagnosing inter-domain routing problems and inter-domain traffic engineering, 2) significant improvements to overlay routing through new streaming multimedia overlay designs and reflector networks optimizations, and 3) optimization of access networks' performance and availability using a novel combination of overlay and IP routing techniques.In addition to the methodology and protocols developed, a significant fraction of the measurements made as part of this research will be made available for research and education. In order to make them available, this project also explores anonymization techniques for network measurements.
