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

提案编号：0435382PI： 布鲁斯麦格斯机构： 卡内基梅隆大学 职务名称：互联网协议和系统设计的测量驱动的方法摘要：互联网的规模和复杂性，今天已经很难为网络研究人员评估的影响，协议的变化可能对其操作。基本的问题是，很难将新协议部署得足够广泛以用于测试目的。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。大规模的测量可以对协议行为进行精确的仿真和基于仿真的评估，因此是对许多协议设计进行“假设”分析的关键。这种从测量到评估的方法使该项目能够对协议和系统设计领域做出重大贡献。 该项目开发了这种新的方法，作为一些具体研究的一部分，结合起来，推动了标准IP和覆盖路由的最新发展。具体而言，该项目预计将作出以下主要贡献：1）结合了用于诊断域间路由问题和域间流量工程的技术的广域IP路由的新颖设计，2）通过新的流式多媒体覆盖设计和反射器网络优化对覆盖路由的显著改进，以及3）使用覆盖和IP路由技术的新颖组合来优化接入网络的性能和可用性。除了所开发的方法和协议之外，作为这项研究的一部分而进行的测量的很大一部分将用于研究和教育。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.
