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.

在过去十年中，互联网已成为信息传播的主要工具之一。 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性质造成了网络上冗余数据越来越多的自然趋势。 虽然已经出现了各种各样的技术来提高网络的效率，但这些技术已经取得了不同程度的成功。 这项职业工作旨在通过透明的带宽节约来开发网络效率的新技术，同时避免与以前的方法相关的许多陷阱。 个别方面的研究包括一个范式转变的方法，多播（隐形多播），冗余数据包动态转换为/从多播，域间对等协议，扩大带宽节约的好处，和广泛的分析/利用现有的应用程序，以增加冗余，但还提高整体系统的效率。此外，该项目还将成为开发面向大规模群体的应用程序的催化剂。 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应用程序如何设计以与底层网络合作产生直接影响。 除了其研究影响，这项工作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开源免费提供的原型传达给工业界和学术界。
