本文重点介绍 COSMOS - 用于城市规模部署的云增强开放软件定义的移动无线测试床。作为 NSF 高级无线研究平台 (PAWR) 计划的一部分，COSMOS 测试台正在西哈莱姆区（纽约市）部署。它将使研究人员能够在最苛刻的现实环境中探索超高带宽和超低延迟的技术“最佳点”。我们描述了测试平台的架构、设计和部署挑战以及在设计和试点部署过程中获得的经验。具体来说，我们描述了 COSMOS 的计算和网络架构、关键构建块及其在不同层的可编程性。这些构建模块包括软件定义无线电、28 GHz 毫米波相控阵模块、光传输网络、核心和边缘云以及控制和管理软件。我们描述了 COSMOS 在密集城市环境中的部署阶段、可以在测试平台中研究的研究领域以及具体的示例实验。最后，我们讨论使用 COSMOS 作为教育工具的经验。
This paper focuses on COSMOS - Cloud enhanced Open Software defined MObile wireless testbed for city-Scale deployment. The COSMOS testbed is being deployed in West Harlem (New York City) as part of the NSF Platforms for Advanced Wireless Research (PAWR) program. It will enable researchers to explore the technology "sweet spot" of ultra-high bandwidth and ultra-low latency in the most demanding real-world environment. We describe the testbed's architecture, the design and deployment challenges, and the experience gained during the design and pilot deployment. Specifically, we describe COSMOS' computing and network architectures, the critical building blocks, and its programmability at different layers. The building blocks include software-defined radios, 28 GHz millimeter-wave phased array modules, optical transport network, core and edge cloud, and control and management software. We describe COSMOS' deployment phases in a dense urban environment, the research areas that could be studied in the testbed, and specific example experiments. Finally, we discuss our experience with using COSMOS as an educational tool.
