The proposed research program will develop and catalyze the core component of a next-generation Internet architecture that greatly increases the functional capabilities, robustness, flexibility, and heterogeneity of the Internet in the face of modern application requirements.Our approach has two inter-related thrusts. The first is to address the following question: What is the right architecture for the next generation of global networking infrastructure? Because proposing a clean-slate design, or treating this question as a thought experiment, has little chance of practical impact, the second thrust is to build the research infrastructure that allows us to discover, evaluate and deploy this architecture.Specifically, overlay networks have recently emerged as a promising technique for introducing disruptive technology into the Internet. This focus on overlay functionality has left unanswered the single most critical question: What lies underneath? What is the appropriate minimal, universally shared environment to underlay the overlays?The core of an underlay that supports an increasing multiplicity of overlay opportunities lies in three key elements. First, there must be some means of information discovery and dissemination through with overlays learn about the underlying Internet; a so-called Information Plane. Second, elevating overlays to first-class objects places special emphasis on the coordinated assignment of complex collections of network resources (e.g., bandwidth, storage, computational cycles, shared information) to competing overlays in an economically coherent, computationally practical fashion. This requires an Economic Framework for resource allocation. Third, there is a complementary question of how to define the basic unit of resource, and the challenges in the implementation of decisions made in resource allocation by means of Virtualization. Combined, these elements form the critical core of an operating environment for overlays; the necessary universal substructure for an overlay-enabled world. These three elements play a pivotal role in this research program: they are both a key objective (output), and at the same time, essential for building a scalable wide-area testbed that allows researchers to evaluate new ideas under real-world conditions.

拟议的研究计划将开发和促进下一代互联网架构的核心组件，在面对现代应用需求时，该架构将大大提高互联网的功能、鲁棒性、灵活性和异构性。我们的方法有两个相互关联的主旨。首先是解决以下问题：下一代全球网络基础设施的正确架构是什么？因为提出一个全新的设计，或者把这个问题当作一个思想实验，几乎没有机会产生实际影响，所以第二个目标是建立研究基础设施，让我们能够发现、评估和部署这个架构。具体来说，覆盖网络最近已经成为一种将颠覆性技术引入互联网的有前途的技术。这种对覆盖功能的关注没有回答一个最关键的问题：下面是什么？ 什么是适合覆盖层底层的最小、普遍共享的环境？支持不断增加的覆盖层机会多样性的底层层的核心在于三个关键要素。 首先，必须有某种信息发现和传播的手段，通过覆盖层了解底层互联网；所谓的信息平面。其次，将覆盖提升为一流对象特别强调以经济上一致、计算上实用的方式将复杂的网络资源集合（例如带宽、存储、计算周期、共享信息）协调分配给竞争覆盖。这需要一个资源分配的经济框架。 第三，还有一个补充问题，即如何定义资源的基本单位，以及通过虚拟化手段进行资源配置决策的实施面临的挑战。这些元素结合在一起，构成了覆盖操作环境的关键核心；覆盖启用的世界所必需的通用基础结构。这三个要素在该研究计划中发挥着关键作用：它们都是关键目标（输出），同时对于构建可扩展的广域测试台至关重要，该测试台使研究人员能够在现实条件下评估新想法。
