项目摘要

Interconnection agreements between Internet Service Providers (ISPs), transit providers, and content delivery networks (CDNs) allow broadband users to transmit traffic to, and receive traffic from, everywhere on the Internet. These agreements are based on a combination of technical issues (e.g. the locations to and from which the provider agrees to route traffic and the amount of traffic exchanged in each direction) and economic issues (e.g. the perceived value of the arrangement and any fees involved). Historically, interconnection agreements consisted of settlement-free peering agreements (between network providers at the same tier) or paid transit agreements (between network providers of different tiers). However, changes in Internet topology resulting from mergers between access and backbone networks and the proliferation of CDNs have resulted in most Internet traffic now flowing through interconnection points between access networks and CDNs. These traffic flows are often subject to a new category of paid peering agreements.In the past five years, disputes over interconnection agreements have occasionally led to failures to augment interconnection capacity, which in turn have harmed the experience of consumers. This project will construct a modern model of Internet interconnection that incorporates both the relevant technical and economic factors. The model will be used to explain and guide new forms of Internet interconnection arrangements. The project will also develop methods to illustrate when Internet interconnection agreements may be used in anticompetitive and discriminatory manners. This project consists of two interrelated efforts. In the development of models of Internet interconnection, the project will investigate the cost factors that should affect interconnection arrangements, including the destinations to which a network operator will route traffic, the volume of traffic, the network cost along that path, and any transit payments required. The project will also investigate the value factors that may affect interconnection arrangements, including the destinations to which an interconnection partner will route traffic, the volume of traffic, and the value of that traffic based on the application. The project will then analyze the variation of the feasible ranges of prices for paid peering with network costs, the maximum that a party is willing to pay, routing and traffic ratios, and competitive pressures.Second, in the development of analytical models of competitive versus anticompetitive behavior, the project will evaluate the characteristics of a variety of interconnection agreements, including the minimum number of interconnection points, routing requirements, capacity augmentation requirements, determinants of payment, and conditions for termination. The project will examine the impact of interconnection prices on broadband providers, content providers, and Internet users, and the resulting impact upon engineering decisions.The project is expected to contribute substantially to the development of network modeling and analysis techniques that integrate technical and economic factors. The expected outcomes of the project will lend insight into commercial interconnection arrangements, as well as into related public policy issues when disputes harm the experience of consumers. The project will also contribute to informing policymakers and their staff about the technical aspects of telecommunication issues.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

互联网服务提供商（isp）、传输提供商和内容交付网络（cdn）之间的互连协议允许宽带用户向互联网上的任何地方发送流量和从任何地方接收流量。这些协议是基于技术问题（例如，提供商同意将流量路由到何处和从何处出发，以及在每个方向上交换的流量数量）和经济问题（例如，安排的感知价值和所涉及的任何费用）的组合。从历史上看，互连协议由免结算对等协议（在同一层的网络提供商之间）或付费传输协议（在不同层的网络提供商之间）组成。然而，由于接入网和骨干网的合并以及cdn的激增，互联网拓扑结构发生了变化，导致大多数互联网流量现在都流经接入网和cdn之间的互连点。这些流量通常受制于一种新的付费对等协议。在过去的五年中，关于互联协议的争议偶尔会导致未能增加互联容量，这反过来又损害了消费者的体验。该项目将构建一个融合相关技术和经济因素的现代互联网互联互通模式。该模型将用于解释和指导互联网互连安排的新形式。该项目还将制定方法，说明互联网互联协议何时可用于反竞争和歧视方式。这个项目由两项相互关联的工作组成。在互联网互连模型的发展过程中，本项目将调查影响互连安排的成本因素，包括网络运营商将把流量路由到的目的地、流量、沿该路径的网络成本，以及所需的任何过路费。该计划亦会研究可能影响互连安排的价值因素，包括互连合作伙伴将把流量路由至的目的地、交通量，以及该交通量的价值。然后，该项目将分析付费对等网络的可行价格范围随网络成本、一方愿意支付的最高价格、路由和流量比率以及竞争压力的变化。其次，在开发竞争与反竞争行为的分析模型时，该项目将评估各种互连协议的特征，包括互连点的最小数量、路由要求、容量增强要求、支付决定因素和终止条件。该项目将研究互连价格对宽带提供商、内容提供商和互联网用户的影响，以及由此对工程决策的影响。预计该项目将对综合技术和经济因素的网络建模和分析技术的发展作出重大贡献。该项目的预期结果将有助于深入了解商业互联安排，以及当争议损害消费者体验时相关的公共政策问题。该项目还将有助于使决策者及其工作人员了解电信问题的技术方面。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
