Despite growing interest in the economic aspects of the Internet, such as network interconnection (peering), pricing, performance, and the profitability of various network types, two historical developments contribute to a persistent disconnect between economic models and actual operational practices on the Internet. First, the Internet became too complex -- in traffic dynamics, topology, and economics -- for currently available analytical tools to allow realistic modeling. Second, the data needed to parameterize more realistic models is simply not available.The problem is fundamental, and familiar: simple models are not valid, and complex models cannot be validated.This project aims to achieve transformative progress in studying economic aspects of the Internet -- network interconnection (peering), pricing, and the profitability of various network types -- by creating more powerful, empirically parameterized computational tools, and enabling broader validation than previously possible. This project will involve measurement of key properties that impact Internet infrastructure economics, such as interdomain traffic, topology dynamics, routing policies and peering practices. These measurements will serve as inputs to a computational model of network interconnection and dynamics. The investigators will validate the model's ability to reproduce known macroscopic properties of the Internet topology, and its ability to reproduce known historical trends in the evolution of the Internet. The investigators will then use the model to study various "what-if" scenarios relating to interdomain interconnection practices, the stability and dynamics of interdomain peering links, and economic properties of provisioning Internet infrastructure.The intellectual merit of this project lies in an approach grounded in empirical measurements of macroscopic Internet topology, traffic demand, routing policies, and peering policies. The data promise to reveal important, and thus far elusive, insights into the economic implications of topology dynamics, interdomain traffic characteristics, and routing policy, but they will also inform the parameterization of a model of network interconnection incentives and dynamics. The broader impact of this project lies in deeper, empirically grounded interpretation of available data on the most opaque sub-discipline of network research -- internetwork economics. The educational side of the project will integrate Internet economics in two Georgia Tech courses, while a PostDoc and a PhD student will graduate as experts in this nascent sub-discipline of Internet research. The data and methods developed during the course of this project will be publicly available and regularly presented to both the research community as well as operator and policy forums, e.g., NANOG, FCC.

尽管对互联网的经济方面的兴趣日益增加，例如网络互连（对等），定价，性能以及各种网络类型的盈利能力，但两种历史发展有助于经济模型与互联网上实际的运营实践之间的持续脱节。 首先，对于目前可用的分析工具，互联网变得过于复杂 - 在交通动态，拓扑和经济学方面，无法实现的建模。 其次，仅仅是不可用的参数化更现实的模型所需的数据。问题是基本和熟悉的：简单的模型无效，并且无法验证复杂的模型。本项目旨在在研究Internet的经济方面（网络互连（Peering），价格），定价），定价和各种网络类型的各种网络类型（通过创建功能强大的效果，可以实现的范围实现的工具，并启用计算性的工具，并实现更强大的计算工具，并实现更强大的计算工具。该项目将涉及影响互联网基础架构经济学的关键特性，例如域间流量，拓扑动态，路由政策和对等实践。这些测量结果将作为网络互连和动态计算模型的输入。研究人员将验证该模型复制互联网拓扑的已知宏观特性的能力，以及其在互联网发展中重现已知历史趋势的能力。然后，研究人员将使用该模型研究与域间互连实践，稳定性和域间对等链接的稳定性和动态以及提供互联网基础架构的经济特性有关的各种“假设”场景。该项目的智力优点在于，该项目的智力优点在于一种基于互联网拓扑的经验测量的方法。该数据有望揭示对拓扑动态，间交通特征和路由政策的经济影响的重要且难以捉摸的见解，但它们还将为网络互连激励措施和动态模型的参数化提供信息。该项目的更广泛影响在于对网络研究最不透明的子学科 - 互联网工作经济学的最不透明的数据进行了更深入，基础的解释。该项目的教育方面将将互联网经济学整合到佐治亚州的两项课程中，而博士后和博士生将毕业于这项互联网研究的新生子学分专家。该项目过程中开发的数据和方法将公开可用，并定期介绍给研究社区以及运营商和政策论坛，例如Nanog，FCC。
