Today's Internet is increasingly expected to support resource-intensive interactive applications, exemplified by the emerging wave of virtual, augmented, and mixed reality applications. Unfortunately, today's public Internet offers a best-effort service, which often falls short of meeting the unprecedented resource requirements and desired goals of these applications. This project aims to achieve high Quality of Service (QoS) for these and other applications by judiciously combining existing Internet resources with additional resources drawn from the cloud, while also being cost-effective for end users. The principal investigators will revisit the QoS problem in the context of the emerging cloud infrastructure: the global footprint of data centers (DC) hosted by major cloud providers. These DCs have good network connectivity (both between data centers as well as to the end-users) but are costly to use. Using extensive network measurements, this project will first quantify the potential benefits of using the cloud as an overlay for wide area communication. Further, it will investigate how best-effort Internet paths can be judiciously combined with cloud overlays to provide bandwidth and latency guarantees to applications, using appropriate and economically efficient pricing mechanisms. The project, if successful, will empower the delivery of high QoS to typical, cost-sensitive end-users, potentially enabling transformative networked applications in areas like healthcare and education. Measurement and protocol insights from this project have the potential to benefit network service providers and network researchers, while students will benefit from new course material and hands-on programming projects.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.

当今的互联网越来越被期望支持资源密集型交互式应用程序，新兴的虚拟、增强和混合现实应用程序浪潮就是例证。不幸的是，当今的公共互联网提供了尽力而为的服务，但往往无法满足这些应用程序前所未有的资源需求和期望目标。该项目旨在通过明智地将现有互联网资源与从云中获取的其他资源相结合，为这些应用程序和其他应用程序实现高质量的服务 (QoS)，同时对最终用户来说也具有成本效益。主要研究人员将在新兴云基础设施的背景下重新审视 QoS 问题：主要云提供商托管的数据中心 (DC) 的全球覆盖范围。这些数据中心具有良好的网络连接（数据中心之间以及最终用户之间），但使用成本昂贵。通过广泛的网络测量，该项目将首先量化使用云作为广域通信覆盖的潜在好处。此外，它将研究如何使用适当且经济高效的定价机制，明智地将尽力而为的互联网路径与云覆盖相结合，为应用程序提供带宽和延迟保证。该项目如果成功，将能够向典型的、对成本敏感的最终用户提供高服务质量，从而有可能在医疗保健和教育等领域实现变革性的网络应用。该项目的测量和协议见解有可能使网络服务提供商和网络研究人员受益，而学生也将从新的课程材料和实践编程项目中受益。该奖项反映了 NSF 的法定使命，并通过使用评估被认为值得支持基金会的智力价值和更广泛的影响审查标准。
