Despite its enormous success, today's Internet suffers certain well-known shortcomings, and is increasingly strained to meet the high availability, reliability, mobility, manageability and security demands of modern applications and services. In contrast, Ethernet is largely plug-&-play; however, this traditional layer-2 technology can hardly meet the scale as well as the efficiency and robustness requirements of emerging and future large, dynamic networks such as data centers and cloud-computing services.In this project, the PI is developing VIRO --- a novel and paradigm-shifting approach to network routing and forwarding. VIRO simultaneously addresses the challenges faced by IP networks and Ethernet by decoupling routing from addressing and by integrating and unifying routing and forwarding performed by the traditional layer-2 and layer 3. VIRO introduces a topology-aware, structured virtual identifier (vid) space onto which both physical identifiers and higher layer addresses/names are mapped. It employs innovative DHT-style routing mechanisms to build end-to-end connectivity from bottom-up, and to route/forward data packets using vids only. Hence, VIRO is not only highly scalable and robust, but also namespace-independent. This research project has the potential to reduce the complexity and costs of operating and managing future large, dynamic networks, and to foster creation and deployment of new Internet services. The PI plans to disseminate the research outcomes through publications and outreach activities. VIRO prototypes will be implemented and made publicly available. Through participation in future Internet design forums and collaboration with industrial partners, the PI will seek to impact the larger industry behind Internet technologies.

尽管取得了巨大的成功，但今天的互联网存在某些众所周知的缺点，并且越来越难以满足现代应用和服务的高可用性、可靠性、移动性、可扩展性和安全性需求。相比之下，以太网在很大程度上是即插&即用;然而，这种传统的第二层技术很难满足新兴的和未来的大型动态网络（如数据中心和云计算服务）的规模、效率和鲁棒性要求。在这个项目中，PI正在开发VIRO --一种新颖的、范式转变的网络路由和转发方法。VIRO同时解决了IP网络和以太网所面临的挑战，将路由从寻址中分离出来，并集成和统一了传统的第2层和第3层执行的路由和转发。VIRO引入了一个拓扑感知的结构化虚拟标识符（VID）空间，物理标识符和更高层的地址/名称都映射到该空间上。它采用创新的DHT式路由机制，自下而上构建端到端连接，并仅使用vid路由/转发数据包。因此，VIRO不仅具有高度的可扩展性和健壮性，而且与命名空间无关。该研究项目有可能降低运营和管理未来大型动态网络的复杂性和成本，并促进新的互联网服务的创建和部署。主要研究者计划通过出版物和外联活动传播研究成果。VIRO原型将被实施并公开提供。通过参与未来的互联网设计论坛和与行业合作伙伴的合作，PI将寻求影响互联网技术背后的更大行业。
