NetSE: Medium: Collaborative Research: Foundational Issues in Network Redundancy Elimination

不同的互联网用户经常访问相似的内容，导致相同的数据反复遍历网络。一些系统已经尝试从网络链路中消除这些冗余数据，以提高网络性能。然而，这些仅适用于点部署，即特定的应用程序、协议或链接。正因为如此，它们的好处是有限的。这个项目开发了一个互联网架构，其中冗余消除（RE）本质上是由网络支持的。该体系结构包含了本地化部署，并将可再生能源的优势扩展到所有端到端流。最重要的是，它改进了应用程序和协议的设计。它使应用程序设计人员不必担心如何有效地使用网络资源。网络协议可以利用固有的正则来更好地满足应用程序和网络约束。这项工作将考虑新架构中的技术、算法和经济问题，包括在网络和终端主机中支持可再生能源，重新配置应用以最佳地利用可再生能源，以及激励isp和终端主机部署可再生能源。智力优势：新架构将提高端到端性能，增强应用和协议，并产生新的应用。该研究将考虑技术、算法和经济问题，以支持可再生能源并最佳地利用它。它将推进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。更广泛的影响：该项目将对未来的应用程序和协议产生广泛的影响。它将改进网络管理和路由。这也将影响ISP的定价。该项目包含大量的教育内容，包括引入新课程和跨站点指导。

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.
