Scientific researchers on university campuses create, analyze, visualize, and share large and diverse datasets from experimental devices like brain scanners, particle colliders, and genome sequencers. However, these "big data" applications place strain on traditional campus networks, due to rapidly increasing volumes of data, the need for either predictably low latency (to adapt experiments in real time) or high throughput (to transfer large data sets between locations), and sophisticated access-control policies (to protect the privacy of human subjects). To enable the next wave of scientific advances, university campuses must find effective ways to meet these challenging demands, at reasonable cost. The emerging technology of Software-Defined Networking (SDN) lowers the barrier to innovation in network management, and can substantially reduce cost through (i) inexpensive commodity network switches, (ii) greater automation of network configuration, and (iii) novel network-management applications that optimize bandwidth usage. Yet, existing innovation in SDN focuses primarily on the needs of commercial cloud providers, rather than the unique requirements of university campuses and scientific researchers. Princeton University is creating a software-defined campus network that can enable the next generation of data-driven scientific research. The initiative brings together big-data science researchers, computer scientists who are experts in SDN, and the campus Office of Information Technology. Princeton is deploying an open-source SDN platform for monitoring and configuring the network, conducting trials of new ways to support big-data applications, and bridging with the larger community, on and off campus, to support the sharing of scientific data, SDN software, and operational experiences.

大学校园的科学研究人员通过大脑扫描仪、粒子对撞机和基因组测序仪等实验设备创建、分析、可视化和共享大量多样的数据集。 然而，这些“大数据”应用程序给传统校园网络带来了压力，因为数据量迅速增加，需要可预测的低延迟（实时调整实验）或高吞吐量（在位置之间传输大型数据集） ，以及复杂的访问控制策略（以保护人类受试者的隐私）。 为了实现下一波科学进步，大学校园必须找到有效的方法，以合理的成本满足这些具有挑战性的需求。 软件定义网络（SDN）的新兴技术降低了网络管理创新的障碍，并且可以通过（i）廉价的商用网络交换机，（ii）更高的网络配置自动化程度，以及（iii）新颖的网络来大幅降低成本。优化带宽使用的管理应用程序。 然而，现有的SDN创新主要关注商业云提供商的需求，而不是大学校园和科学研究人员的独特需求。 普林斯顿大学正在创建一个软件定义的校园网络，可以实现下一代数据驱动的科学研究。 该倡议汇集了大数据科学研究人员、SDN 专家计算机科学家以及校园信息技术办公室。 普林斯顿大学正在部署一个开源 SDN 平台来监控和配置网络，尝试支持大数据应用的新方法，并与校园内外更大的社区建立桥梁，以支持科学数据、SDN 软件的共享，以及运营经验。
