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催化下一代互联网架构的核心组成部分，大大增加了功能的能力，鲁棒性，灵活性和异构性的互联网在面对现代应用程序的需求。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，或把这个问题作为一个思想实验，几乎没有机会产生实际影响，第二个推力是建立研究基础设施，使我们能够发现，评估和部署这种架构。具体来说，覆盖网络最近出现作为一个有前途的技术，引入互联网的颠覆性技术。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？ 什么是适当的最小的，普遍共享的环境来覆盖？支持越来越多的叠加机会的底层的核心在于三个关键要素。 首先，必须有一些信息发现和传播的手段，通过覆盖了解底层互联网;所谓的信息平面。第二，将覆盖提升为第一类对象特别强调网络资源的复杂集合的协调分配（例如，带宽、存储、计算周期、共享信息）以经济上一致的、计算上实用的方式竞争覆盖。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，以及通过虚拟化实现资源分配决策的挑战。结合起来，这些元素构成了覆盖操作环境的关键核心;覆盖启用世界的必要通用子结构。这三个要素在该研究计划中发挥着关键作用：它们既是关键目标（输出），同时也是构建可扩展的广域测试平台的关键，该平台允许研究人员在现实条件下评估新想法。
