The Internet has undergone tremendous growth recently, fueled by the emergence of user-generated video, TV- and movie-on-demand services, peer-to-peer file sharing, social networking, and rapid proliferation of smart phones. These new application mixes and the resulting characteristics of network traffic have raised numerous research challenges for practitioners working on various aspects of networks including construction, routing, and staged deployment. As a result, "network design" or more generally "networking," with its many variants, is one of the most active research areas in computer science.Theoretical modeling of networks plays a vital role in understanding computer and communication networks. Examples of such theoretical models that will be addressed further in this project are cost and efficiency optimizations with applications in Fiber Optic Networks, Content Distribution Networks (CDNs), Virtual Private Networks (VPNs), Cellular Networks, and Social Networks. The Principal Investigator will invent and use a variety of techniques in approximation and randomized algorithms, fixed parameter algorithms, algorithmic game theory, and his own Bidimensionality theory, to optimize cost and performance of these strategic networks.As a broader impact, the PI seeks to leverage his network of collaborators to apply these theoretical developments to the design of practical algorithms and mechanisms, to deploy them in real-world settings, and to perform experiments to characterize and explain their behavior and performance. The PI believes that variations of the algorithms designed in this project will be used in real networks, enabling faster networks and cheaper Internet access in practice. This is an especially important goal since the Internet in the U.S. is currently not as fast or cheap as in several other developed or even developing countries.The wealth of attractive open problems in foundations of network design provide, at one extreme, challenging research topics, and at the other extreme, intuitive and accessible problems to inspire students to enter research in computer science, mathematics, and economics. The educational thrust of this project is to actively engage undergraduate and graduate students in study of and research into network design foundations.

互联网最近经历了巨大的增长，由用户生成的视频，电视和电影点播服务，点对点文件共享，社交网络的出现，以及智能手机的快速普及推动。这些新的应用程序混合和由此产生的网络流量的特点提出了许多研究挑战的从业者在网络的各个方面，包括建设，路由和分阶段部署。因此，“网络设计”或更广义的“网络”及其许多变体是计算机科学中最活跃的研究领域之一。网络的理论建模在理解计算机和通信网络方面起着至关重要的作用。在本项目中将进一步讨论的此类理论模型的示例是光纤网络、内容分发网络（CDN）、虚拟专用网络（VPN）、蜂窝网络和社交网络中的应用的成本和效率优化。主要研究者将发明并使用近似和随机算法、固定参数算法、算法博弈论和他自己的二维理论中的各种技术，以优化这些战略网络的成本和性能。作为更广泛的影响，PI寻求利用他的合作者网络将这些理论发展应用于实际算法和机制的设计，将它们部署在真实世界的环境中，并进行实验来描述和解释它们的行为和性能。PI认为，该项目中设计的算法变体将用于真实的网络，从而实现更快的网络和更便宜的互联网接入。这是一个特别重要的目标，因为美国的互联网目前不像其他几个发达国家甚至发展中国家那样快速或便宜。网络设计基础中大量有吸引力的开放问题，一方面提供了具有挑战性的研究课题，另一方面，直观和易于理解的问题，激励学生进入计算机科学，数学和经济学的研究领域。该项目的教育主旨是积极吸引本科生和研究生学习和研究网络设计基础。
