POSE: Phase II: Open-Source Precision, High Accuracy and Security Environment (OpenPHASE) For Time Verification, Calibration, and Interoperability

当前研究和开发的重要领域以及现有的操作系统都依赖于高精度、亚纳秒级的分布式计时解决方案。 白色兔子是一个解决方案，由欧洲核子研究中心开发，用于大型强子对撞机，作为一个开源的硬件，固件和软件系统，通过以太网网络实现亚纳秒同步。 白色兔子在高能物理、聚变研究和量子网络等许多领域的使用和应用都有所增长。 高精度定时解决方案对于大型分布式数据库、确定性时间敏感电信以及先进制造等领域的网络物理系统也越来越重要。实现开源生态系统的途径，在本文中称为用于时间验证，校准和互操作性的开源精度，高精度和安全环境，通过指导委员会与相关行业论坛，国际标准和其他利益相关者协调，以帮助指导和塑造不断增长的社区，以鼓励进一步的入职，开发人员参与，并为最终用户的反馈提供了一条途径。 这项工作的主要重点是白色兔子开源生态系统的发展，使社区能够访问资源来验证，测量和校准他们的系统。 这项工作建立并扩展了验证开源高精度计时解决方案（如白色兔子）的最佳实践，并在可能的情况下开发开源解决方案，例如用于校准过程的自动化。 这一努力促进了解决方案的加速部署，同时保持了最终用户对开源解决方案的信心，以提高其采用率。 这项工作使开源社区能够利用资源和流程来集成新的和更新的开源硬件，并对其开源固件和软件更新进行持续集成测试。 该奖项反映了NSF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。

Significant areas of current research and development, as well as existing operational systems, rely on high-accuracy, sub-nanosecond, distributed timing solutions. White Rabbit is a solution, developed by CERN for use in the Large Hadron Collider, as an open-source hardware, firmware, and software system that enables sub-nanosecond synchronization via ethernet networking. White Rabbit has since grown in its use and application in many areas of high-energy physics, fusion research, and quantum networking as examples. High accuracy timing solutions are also increasingly critical to large distributed databases, deterministic time-sensitive telecommunications, and cyber-physical systems in areas such as advanced manufacturing. The pathway to enable an Open Source Ecosystem, titled herein as the Open-Source Precision, High Accuracy and Security Environment For Time Verification, Calibration, and Interoperability, coordinates with related industry forums, international standards, and other stakeholders through a steering committee to help direct and shape the growing community to encourage further onboarding, developer engagement, and provide a path for end-user feedback to be addressed. The principal focus of this effort is the growth of the White Rabbit open-source ecosystem, enabling the community with access to resources to validate, measure, and calibrate their systems. The work establishes and expands best practices in validating open-source high-accuracy timing solutions such as White Rabbit, and where possible, develop open-source solutions, e.g. for automation of calibration processes. The effort fosters accelerated deployment of solutions while maintaining end-user confidence in the open-source solutions to grow their adoption. The work enables the open source community with the resources and process to integrate new and updated open-source hardware and perform continuous integration testing of their open-source firmware and software updates. Resources are remotely accessible to the global members who will help shape the direction and growth of the ecosystem.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.
