Open Exchange Points (OXPs) serve as meet points for connecting and facilitating the exchange of data between Research and Education (R&E) networks. They are critical cyberinfrastructure in the transit of data over long geographical distances, switching data flows from one R&E network to the next, to its destination. For example, data from the Vera Rubin Observatory will transit 6 OXPs as it moves from the southern to northern hemispheres. Operationalizing the transit of data flows across OXPs is increasingly important to minimize the impact from events on network services (hardware failures and soft failures). End-to-end network paths for these data flows are not under the control of any individual organization. Multiple R&E network operators must coordinate to establish geographically distributed end-to-end paths – an effort that can take days to weeks.Florida International University (FIU), University of Southern California – Information Sciences Institute (USC-ISI) and University of North Carolina at Chapel Hill - RENCI are furthering AtlanticWave-SDX: a distributed experimental SDX, supporting research, experimental deployments, prototyping and interoperability testing, on national and international scales. AtlanticWave-SDX leverages innovations from the initial AtlanticWave-SDX project, introducing new capabilities, enabling OXPs to react to unplanned network events by adding intelligent closed-loop control of network services powered by in-band network telemetry.AWAVE-SDX is comprised of two components: An infrastructure development component with optical super channels to reframe and reprovision network capacity between R&E backbone networks; An innovation component to build a distributed intercontinental experimental SDX by leveraging OXPs in the U.S., Chile, Brazil, and S. Africa.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.

开放交换点（OXP）作为连接和促进研究和教育（RE）网络之间数据交换的交汇点。它们是长距离传输数据的关键网络基础设施，将数据流从一个R E网络切换到下一个，再到其目的地。例如，来自维拉鲁宾天文台的数据将在从南半球向北方半球移动时经过6个OXP。为了最大限度地减少事件对网络服务（硬件故障和软故障）的影响，跨OXP的数据流传输操作化变得越来越重要。这些数据流的端到端网络路径不受任何单个组织的控制。多个R& E网络运营商必须进行协调，以建立地理上分布的端到端路径-这一工作可能需要数天到数周的时间。佛罗里达国际大学（FIU）、南加州大学信息科学研究所（USC-ISI）和北卡罗来纳州大学查佩尔山- RENCI正在进一步推进AntiticWave-SDX：分布式实验SDX，支持国家和国际规模的研究，实验部署，原型设计和互操作性测试。AWAVE-SDX利用了最初的AWAVE-SDX项目的创新，引入了新的功能，使OXP能够通过添加由带内网络遥测提供动力的网络服务的智能闭环控制来对计划外网络事件做出反应。AWAVE-SDX由两个组件组成：具有光学超级信道的基础设施开发组件，用于在RE骨干网络之间重新构建和重新提供网络容量;创新组件，用于通过利用美国的OXP来构建分布式洲际实验SDX，智利、巴西和S.该奖项反映了NSF的法定使命，并被认为值得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来支持。
