CAREER: Transparent Bandwidth Conservation Techniques

在过去的十年里，互联网已经成为传播信息的主要工具之一。随着应用程序和信息源在范围和规模上的增加，互联网的传统点对点特性已经形成了整个网络中日益冗余的数据的自然趋势。虽然出现了各种各样的技术来提高网络的效率，但这些技术都取得了不同程度的成功。这项职业工作旨在开发新的技术，通过透明的带宽节约来提高网络效率，同时避免与以前方法相关的许多陷阱。研究的个别方面包括多播的范式转换方法(隐形多播)，其中冗余分组被动态地转换为多播或从多播动态转换，用于扩展带宽节约的好处的域间对等协议，以及对现有应用的广泛分析/利用以增加冗余但仍可提高整体系统效率。此外，该项目还将成为大规模面向群体的应用程序开发的催化剂。此外，这项工作将对互联网的效率、服务质量定价和资源管理以及如何设计应用程序以与底层网络合作产生直接影响。除了其研究影响之外，这项工作还将通过对课堂方法和学生发展竞赛的创新研究直接影响教育。研究结果还将通过开发可通过开放源码免费获得的原型传达给工业界和学术界。

Over the past decade, the Internet has emerged as one of the primary tools for information dissemination. The traditional point-to-point nature of the Internet has created a natural trend of increasingly redundant data across the network as applications and information sources increase in both scope and scale. While a wide variety of techniques have emerged to increase the efficiency of the network, the techniques have met with varying degrees of success. This career work aims to develop novel techniques for network efficiency through transparent bandwidth conservation while avoiding many of the pitfalls associated with previous approaches. Individual facets of the research include a paradigm-shifting approach to multicast (stealth multicast) whereby redundant packets are dynamically converted to/from multicast, inter-domain peering protocols for expanding the benefits of bandwidth conservation, and extensive analsis/exploitation of existing applications to increase redundancy but yet improve overall system efficiency. In addition, this project will serve as a catalyst for the development of large-scale group oriented applications. Furthermore, the work will have a direct impact on the efficiency of the Internet, Quality-of-Service pricing and resource management, and how applications are designed to cooperate with the underlying network. Beyond its research impact, this work will directly impact education through innovative studies on classroom methodologies and student development contests. The results will also be conveyed to industry and academia through the development of prototypes freely available via open-source.
