NeTS: Small: VIRO: Highly Scalable, Robust and Namespace Independent Routing for Future Networks

尽管取得了巨大的成功，但当今的互联网仍存在一些众所周知的缺点，越来越难以满足现代应用程序和服务的高可用性、可靠性、移动性、可管理性和安全性要求。相比之下，以太网在很大程度上是即插即用的；然而，这种传统的第二层技术很难满足新兴和未来大型、动态网络(如数据中心和云计算服务)的规模以及效率和健壮性要求。在这个项目中，PI正在开发一种新颖的、改变模式的网络路由和转发方法--Viro。Viro通过将路由与寻址分离，并通过集成和统一传统的第2层和第3层执行的路由和转发，同时解决了IP网络和以太网面临的挑战。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。它采用创新的分布式哈希表风格的路由机制来建立自下而上的端到端连接，并仅使用VID来路由/转发数据分组。因此，Viro不仅具有高度的可伸缩性和健壮性，而且与命名空间无关。这一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，并促进新互联网服务的创建和部署。国际和平协会计划通过出版物和外展活动传播研究成果。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。

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.
