It has long been recognized that the Internet lacks the flexibility to provide enhanced services. While proposals to augment the Internet abound, efforts to modify its infrastructure have essentially failed. As a response, overlay networking gained attention as a viable an approach to provide enhanced Internet services. Another response has been the push to define a new clean-slate Internet architecture. Network virtualization is emerging as a promising new central feature of the future Internet architecture. Interestingly, but perhaps not surprisingly, the use of overlay networking in the current Internet, as well as the potential deployment of network virtualization in a future Internet both result in what we dub as multi-layered networks. The goal of this project is to undertake a systematic investigation of this paradigm, focusing primarily on routing functions. The research aims to provide a unified understanding that will be applicable in both current and future Internet environments. The project also aims to articulate fundamental differences between current and future environments that will affect how we use or design multi-layered networks. A central concern is the interaction between routing protocols in the multiple layers. Broader Impact: Since the project considers both the current and a future Internet, results from this project will more broadly help improve our understanding of network virtualization in a future Internet and how it can achieve its full potential. The PI is also committed to activities with additional broader impact including: development of modules based on our research for classes and continued emphasis on inclusion of under-represented groups within the research.

人们早就认识到，互联网缺乏提供增强服务的灵活性。虽然增强互联网的提议比比皆是，但修改其基础设施的努力基本上失败了。作为一种回应，覆盖网络作为一种提供增强Internet服务的可行方法而受到关注。另一种回应是推动定义一种全新的互联网架构。网络虚拟化正在成为未来Internet架构的一个有前途的新中心特征。有趣的是，但也许并不令人惊讶的是，当前Internet中覆盖网络的使用，以及未来Internet中网络虚拟化的潜在部署，都导致了我们所称的多层网络。这个项目的目标是对这个范例进行系统的研究，主要集中在路由功能上。这项研究的目的是提供一个统一的理解，将适用于当前和未来的互联网环境。该项目还旨在阐明当前和未来环境之间的根本差异，这些差异将影响我们如何使用或设计多层网络。一个中心问题是多层路由协议之间的交互。更广泛的影响：由于该项目考虑了当前和未来的互联网，因此该项目的结果将更广泛地帮助我们更好地理解未来互联网中的网络虚拟化，以及它如何实现其全部潜力。PI还致力于具有更广泛影响的活动，包括：根据我们的课程研究开发模块，并继续强调在研究中纳入代表性不足的群体。
