软件定义网络（SDN）正在推动研究和教育（R&E）网络的转型，实现网络研究的创新，提高网络性能，并通过策略驱动的网络管理框架提供安全性。内布拉斯加大学林肯分校（UNL）的荷兰计算中心（HCC）支持研究大型数据集的科学家，并确定了网络管理和安全性的灵活性需求，特别是在识别数据流方面。这个问题通过部署生产SDN来解决，重点是集成大规模GridFTP数据传输的网络资源管理。我们提出了SNAG（SDN管理的GridFTP传输网络架构），一个架构，使基于SDN的网络管理的GridFTP文件传输的大规模科学数据集。我们还展示了SNAG如何有效和安全地识别来自紧凑型μ子螺线管（CMS）和激光干涉仪引力波天文台（LIGO）等项目的科学数据集传输。我们专注于公开一个应用程序编程接口（API）之间的可信GridFTP进程和网络层，允许网络跟踪流通过应用程序元数据。
Software Defined Networking (SDN) is driving transformations in Research and Education (R&E) networks, enabling innovations in network research, enhancing network performance, and providing security through a policydriven network management framework. The Holland Computing Center (HCC) at the University of Nebraska-Lincoln (UNL) supports scientists studying large datasets, and has identified a need for flexibility in network management and security, particularly with respect to identifying data flows. This problem is addressed through the deployment of a production SDN with a focus on integrating network resource management for large-scale GridFTP data transfers. We propose SNAG (SDN-managed Network Architecture for GridFTP transfers), an architecture that enables the SDN-based network management of GridFTP file transfers for large-scale science datasets. We also show how SNAG can efficiently and securely identify science dataset transfers from projects such as Compact Muon Solenoid (CMS) and Laser Interferometer Gravitational-Wave Observatory (LIGO). We focus on exposing an Application Program Interface (API) between the trusted GridFTP process and the network layer allowing the network to track flows via application metadata.
