As the Internet grows larger and more complex, it becomes exceedingly difficult to reason about its structural properties because there exists no scalable method to map the Internet's crucial structural properties such as connectivity, delay and bandwidth. The lack of such structural information in efficiently accessible form leads to poorly functioning and excessively complex network software and protocols. The Internet Geometry project aims to develop geometric models of the Internet's crucial structural properties, much like their geometric longitudes and latitudes can represent distances between locations on the Earth. Geometric models are inherently simple and scalable, and thus can enable a wide variety of scalable performance-aware protocols and applications. The expected contributions of this CAREER research project include new fundamental understanding of the geometric properties of the Internet by studying extensive Internet structural data and new methods to generate accurate network geometric models. The PI will work towards a public global-scale distributed system that enables all Internet nodes to independently compute their network geometric properties, and simple and scalable protocols and systems for network routing and distributed system self-organization enabled by network geometric models.

随着互联网变得越来越大和越来越复杂，对其结构属性进行推理变得非常困难，因为没有可扩展的方法来映射互联网的关键结构属性，如连通性、延迟和带宽。缺乏有效可访问形式的这种结构信息导致功能不佳且过于复杂的网络软件和协议。互联网几何项目旨在开发互联网关键结构属性的几何模型，就像它们的几何经度和纬度可以代表地球上各个地点之间的距离一样。几何模型本质上简单且可扩展，因此可以支持各种可扩展的性能感知协议和应用。这一职业研究项目的预期贡献包括通过研究大量的互联网结构数据来对互联网的几何属性有新的基本理解，以及生成准确的网络几何模型的新方法。PI将致力于建立一个公开的全球规模的分布式系统，使所有互联网节点能够独立计算其网络几何属性，并通过网络几何模型实现简单且可扩展的网络路由和分布式系统自组织的协议和系统。
