SoCS: Leveraging Shared Social Interest in a Content Centric Internet

在过去的半个世纪里，互联网已经从一种资源共享的媒介转变为一种以访问和分发内容为中心的媒介。这项研究工作利用社会科学研究的见解来表征对内容分发服务的共同兴趣，并探索这些发现对现有和未来服务设计的影响。它的议程基于这样一种观察，即彻底了解对内容的共同兴趣--人们希望在何时何地共享什么内容--是设计、实施和管理内容分发服务的关键，它决定了这些服务的架构和动态组织，确定了用户体验的性能及其对底层网络的影响。这项工作利用流行的内容分发系统中用户的观点来探索内容分发的这些和其他方面，并作为一个试验台，以获得对共同兴趣和内容分发网络的演变和动态的社会科学见解。广泛的影响：这项努力的研究成果将以出版物、数据集和软件的形式提供。如果适用，该软件将在我们之前成功的基础上，集成到BitTorrent等现有系统中。拟议工作的影响自然会延伸到现有服务和网络之外，通过与互联网工程任务组和合作研究实验室的密切互动，为未来内容分发服务和新的以内容为中心的互联网架构的设计提供信息。除了前景看好的研究问题和实际效益外，该项目还将对通信、网络和分布式系统方面的教育产生直接影响。

Over the last half century, the Internet has moved from a medium for resource sharing to one centered on the access and distribution of content. This research effort leverages insights from social science research to characterize shared interest in content distributing services and explore the implications of these findings on the design of existing and future services. Its agenda is predicated on the observation that a thorough understanding of shared interest in content - what content people want to share, when, and where - is key to the design, implementation and management of content distribution services, dictating these services' architectures and dynamic organizations, determining performance experienced by users and the impact they have on the underlying network. The effort leverages the view of users in a popular content distribution system to explore these and other aspects of content distribution and serve as a testbed for gaining social scientific insights in the evolution and dynamics of shared interest and content distribution networks.Broader Impact: Research findings from this effort will be made available as publications, datasets and software. When applicable, the software will be integrated into existing systems such as BitTorrent, building on our previous successes. The impact of the proposed work will naturally extend beyond existing services and networks to inform the design of future content distribution services and new content-centric Internet architectures through close interaction with the Internet Engineering Task Force and collaborating research labs. In addition to the promising research questions and practical benefits, the project will have a direct impact on education in communication, network and distributed systems.
