CI-ADDO-EN: Major Equipment Upgrade and Improved Operations Support for the ORBIT Open Access Wireless Networking Testbed

罗格斯大学下一代无线网络的轨道开放接入试验台的开发是为了应对支持现实和可重复的大规模无线网络实验的挑战。由400个节点组成的轨道无线电网格于2005年作为社区资源发布，研究人员可以通过互联网门户网站(www.Orbit-Lab.org)访问该网格，该门户网站提供各种服务，帮助用户进行实验设置、控制和测量。该项目旨在对构成轨道试验台的计算设备和测量仪器进行重大硬件升级。正在升级的具体设备包括：-所有400个轨道无线电节点，作为实验者的主要计算平台。-轨道后端集群中的计算/存储服务器和交换设备。-无线电电网频谱监测的射频测量仪器。该项目还包括作为社区资源持续24/7运行轨道设施所需的持续维护和软件支持的资源。拟议的设备升级将为新兴无线技术和网络架构的预期更高性能试验做好轨道准备。升级后的Orbit试验台将支持的具体实验研究领域包括动态频谱接入、认知网络、无线安全、容迟路由协议和网络虚拟化。作为一个开放的社区设施，Orbit有助于降低在无线网络上进行实验的门槛，从而提高现场的教学和研究效率。该试验台目前是NSF计算机科学和工程界未来互联网体系结构研究的无线方面的重要平台。

The ORBIT open access testbed for next-generation wireless networking at Rutgers was developed to address the challenge of supporting realistic and reproducible wireless networking experiments at scale. The 400-node ORBIT radio grid was released as a community resource in 2005, and can be accessed by researchers via an Internet portal (www.orbit-lab.org) which provides a variety of services to assist users with experiment setup, control and measurement. This project is aimed at a major hardware upgrade of the computing equipment and measurement instruments which make up the ORBIT testbed. Specific equipment items being upgraded are:- All 400 ORBIT radio nodes which serve as the primary computing platform for experimenters.- Computing/storage servers and switching equipment in the ORBIT backend cluster.- RF measurement instruments for spectrum monitoring on the radio grid.This project also includes resources for ongoing maintenance and software support necessary for continued 24/7 operation of the ORBIT facility as a community resource. The proposed equipment upgrade will prepare ORBIT for anticipated higher performance experiments on emerging wireless technologies and network architectures. Specific areas of experimental research that will be enabled by the upgraded ORBIT testbed include dynamic spectrum access, cognitive networking, wireless security, delay-tolerant routing protocols and network virtualization. As an open community facility, ORBIT helps lower the barrier for experimentation on wireless networks, thus improving teaching and research productivity in the field. The testbed currently serves as an important platform for wireless aspects of future Internet architecture research in the NSF computer science and engineering communities.
