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ORBIT开放接入测试平台的开发旨在解决支持大规模真实和可重复无线网络实验的挑战。 400个节点的ORBIT无线电网格于2005年作为社区资源发布，研究人员可通过互联网门户网站（www.orbit-lab.org）访问，该门户网站提供各种服务，协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。 - 所有400个ORBIT无线电节点，作为实验人员的主要计算平台。ORBIT后端集群中的计算/存储服务器和交换设备。用于无线电网络频谱监测的射频测量仪器，该项目还包括用于持续维护的资源和作为社区资源的轨道设施连续24/7运行所需的软件支持。 拟议的设备升级将使ORBIT为对新兴无线技术和网络结构进行预期的更高性能实验做好准备。 升级后的ORBIT测试平台将支持的实验研究的具体领域包括动态频谱接入、认知网络、无线安全、延迟容忍路由协议和网络虚拟化。 作为一个开放的社区设施，ORBIT有助于降低无线网络实验的障碍，从而提高该领域的教学和研究效率。 该测试平台目前是NSF计算机科学和工程界未来互联网架构研究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.
