IRNC: Testbed: COSMOS Interconnecting Continents (COSMIC)

该项目支持使用独特的可编程无线、光学和边缘云网络测试平台基础设施进行国际协作实验。它建立在PAWR COSMOS （NYC）和ORBIT （NJ）测试平台与对等（美国/国际）和FABRIC（美国）测试平台的接口上，并增加了与国际测试平台的连接，包括CPQD（巴西），Kyutech/StarBED（日本），OneLab/NITOS（欧盟/希腊）和CONNECT（爱尔兰）。为了支持跨层国际实验，开发了独特的功能，包括Mininet网络模拟器的光学和BGP扩展，以及用于跨层BGP功能和受控公共互联网实验的对等测试平台工具。该项目为从应用到光学和无线电物理层的网络研究创建了一个强大的国际实验平台。展示各种能力并激励进一步实验的几个不同示例实验包括：(i)远程科学实验期间在分解基础设施上实现多层服务质量的人工智能；（ii）跨网络域和试验台对延迟和容量敏感的移动应用程序进行云处理；（三）跨国界的域间路由、数据安全和隐私。一个旨在扩大对计算机的参与的强有力的外联组成部分使当地的哈莱姆中学和高中教师参与研究和发展教育组成部分。最后，基于仿真的沙盒国际实验能力的发展有望使这种大规模实验更容易为广泛的研究人员所接受。因此，由于独特的国际基础设施的可用性，该项目有可能支持增强未来网络性能的实验，并有助于弥合数字鸿沟。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The project enables the use of unique programmable wireless, optical, and edge-cloud network testbed infrastructure for international collaborative experiments. It builds on the interfaces of the PAWR COSMOS (NYC) and ORBIT (NJ) testbeds with the PEERING (US/International) and FABRIC (US) testbeds, and adds connections to international testbeds, including CPQD (Brazil), Kyutech/StarBED (Japan), OneLab/NITOS (EU/Greece), and CONNECT (Ireland). To support cross-layered international experiments, unique capabilities are developed, including optical and BGP extensions to the Mininet network emulator, and PEERING testbed tools for cross-layer BGP functions and controlled public Internet experimentation.The project creates a powerful international experimental platform for networking research from applications down to the optical and radio physical layers. A few distinct example experiments that demonstrate various capabilities and motivate further experimentation include: (i) Artificial Intelligence for multi-layer Quality of Service over disaggregated infrastructure during remote scientific experimentation; (ii) cloud processing of latency- and capacity-sensitive mobile applications across network domains and testbeds; and (iii) interdomain routing, data security, and privacy across national boundaries.A strong outreach component aiming at broadening participation in computing involves local Harlem middle and high school teachers in research and in development of educational components. Finally, the development of emulation-based sandbox capabilities for international experiments promises to make such large-scale experiments more accessible to a wide range of researchers. Therefore, and due to the availability of a unique international infrastructure, the project has the potential to support experimentation that enhances the performance of future networks and helps bridge the digital divide.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
