For a growing number of data-intensive research projects spanning a wide range of disciplines, high-speed network access to computation and storage -- located either locally in the campus or in the cloud (e.g., at national labs) -- has become critical to the research. While old, slow, campus network infrastructure is a key contributor to poor performance, an equally important contributor is the problem of bottlenecks that arise at security and network management policy enforcement points in the network.This project aims to dramatically improve network performance for a wide range of researchers across the campus by removing many of the bottlenecks inherent in the traditional network infrastructure. By replacing the existing network with modern software defined network (SDN) infrastructure, researchers will benefit from both the increased speed of the underlying network hardware and also from the ability to utilize SDN paths that avoid traditional policy enforcement bottlenecks. As a result, researchers across the campus will see significantly faster data transfers, enabling them to more effectively carry out their research.This project builds on and extends a successful initial SDN deployment at the University of Kentucky, adding SDN switches to ten research buildings and connecting each of them to the existing SDN research network core with 40G uplinks. To ensure high-speed access to the Internet/Cloud, the research core network is being linked through a new 100 Gbps link to Internet2. Research traffic in the enabled buildings is automatically routed onto the SDN research network where SDN flow rules allow research traffic to bypass legacy network infrastructure designed to police normal traffic. By extending the SDN network capabilities to several new buildings on campus, a wide range of researchers are able to archive significantly higher network throughput for their research data.

对于越来越多的数据密集型研究项目，涵盖了广泛的学科，高速网络可以访问计算和存储 - 位于校园或云中（例如，在国家实验室） - 对研究至关重要。 虽然古老，缓慢，校园网络基础设施是导致性能差的关键因素，但同样重要的贡献者是在网络中的安全和网络管理政策执法点出现的瓶颈问题。该项目旨在通过拆除许多传统网络内置的网络来改善校园各种研究人员的网络性能，从而极大地提高网络性能。 通过使用现代软件定义网络（SDN）基础架构代替现有网络，研究人员将受益于基础网络硬件的提高速度，也将从利用SDN路径的能力中受益。 结果，整个校园的研究人员将看到更快的数据传输，使他们能够更有效地进行研究。该项目基于肯塔基大学的成功并扩展了成功的初始SDN部署，并将SDN开​​关添加到了十座研究建筑中，并将其连接到现有的SDN研究网络与40G Uplinks的现有研究网络核心。为了确保对Internet/Cloud的高速访问，研究核心网络正在通过新的100 Gbps链接链接到Internet2。 启用建筑物中的研究流量将自动路由到SDN研究网络，在该网络中，SDN流量规则允许研究流量绕过旨在监管正常流量的传统网络基础架构。 通过将SDN网络功能扩展到校园的几座新建筑物，许多研究人员能够为其研究数据归档更高的网络吞吐量。
