Different Internet users often access similar content resulting in identical data repeatedly traversing the network. Several systems have attempted to eliminate this redundant data from network links to improve network performance. However, these only apply to point-deployments, i.e. to specific applications, protocols, or links. Because of this, their benefits are limited.This project develops an Internet architecture where redundancy elimination (RE) is inherently supported by the network. This architecture subsumes localized deployments and extends the benefits of RE to all end-to-end flows. Crucially, it improves the design of applications and protocols. It frees application designers from concerns about using network resources efficiently. Network protocols can leverage inherent RE to better meet application and network constraints. This work will consider the technical, algorithmic and economic issues in this new architecture, including supporting RE in networks and end-hosts, reconfiguring applications to optimally leverage RE, and incentives for ISPs and end-hosts to deploy RE.Intellectual merit: The new architecture will improve end-to-end performance, enhance applications and protocols, and give rise to new applications. The research will consider technical, algorithmic, and economic issues in supporting RE and leveraging it optimally. It will advance various fields of Computer Science, including network hardware, protocols and applications, algorithms, game-theory and network economics.Broader impact: This project will have a broad impact on future applications and protocols. It will improve network management and routing. It will also impact ISP pricing. The project has a substantial educational component involving the introduction of new courses and cross-site mentoring.

不同的互联网用户经常访问相似的内容，导致相同的数据在网络中反复传输。几个系统已经尝试从网络链路中消除这种冗余数据，以提高网络性能。但是，这些仅适用于点部署，即特定的应用程序、协议或链路。因此，它们的好处是有限的。该项目开发了一种互联网体系结构，其中冗余消除(RE)本质上是由网络支持的。此架构包含本地化部署，并将RE的优势扩展到所有端到端流。至关重要的是，它改进了应用程序和协议的设计。它将应用程序设计人员从高效使用网络资源的顾虑中解放出来。网络协议可以利用固有的RE来更好地满足应用和网络约束。这项工作将考虑这个新架构中的技术、算法和经济问题，包括支持网络和终端主机中的RE，重新配置应用程序以最佳地利用RE，以及激励运营商和终端主机部署RE。智力优势：新架构将提高端到端性能，增强应用程序和协议，并产生新的应用程序。这项研究将考虑支持可再生能源和优化利用可再生能源的技术、算法和经济问题。它将推动计算机科学的各个领域，包括网络硬件、协议和应用、算法、博弈论和网络经济学。广泛影响：该项目将对未来的应用和协议产生广泛影响。它将改善网络管理和路由。它还将影响互联网服务提供商的定价。该项目有大量的教育内容，包括采用新课程和跨地点辅导。
