CC*DNI Integration: PROnet: A PRogrammable Optical Network Prototype Serving the Campus

如果没有高性能网络，大数据和高性能计算的价值就非常有限。 长期以来，人们一直认为，最高性能的数据传输应该直接在光纤电路上运行，而无需以太网交换或IP路由。 这种直接分层避免了与交换相关的数据包丢失，并提供了一种具有成本效益的服务。 现在存在允许动态建立单个应用光路的光学设备。 但是，设置光路所需的时间对于短或小的传输来说太长了吗？花一秒钟来建立100千兆位/秒的链路以便传输小文件是没有意义的。 该项目正在建设一个综合校园网络，其中小数据传输（兆字节或千兆字节）乘坐传统网络和大数据传输（兆字节或千兆字节）直接乘坐光学电路。该项目正在建设PROnet，这是德克萨斯大学达拉斯的一个校园网络，它提供了尽可能低的网络延迟（仅信号传播），可扩展到100 Gbps及以上，以及具有低功耗和复杂性的设备。一个用户友好的界面将开发和部署的网络经验不足的研究人员要求提供所需的光学。将开发一个PROnet控制器，用于光路的调度和自动配置，这将通过从整个过程中消除人为干预来显著缩短电路预留程序时间。在跨域操作方面，开放平台OSCARS将扩展到与PROnet一起使用。有了这个OSCARS扩展，跨多个（光和非光）域的混合（光和虚拟）电路的配置将成为现实。 该软件将支持通过InCommon身份安全使用网络。

Without high-performance networking big data and high performance computing have very limited value. It has long been recognized that the highest performance data transfers should directly run the on top of optical circuits without Ethernet switching or IP routing. This direct layering avoids switching-related packet loss and provides a cost effective service. Optical equipment now exists that will permit the dynamic establishment of single application light paths. However, the time required to set up optical circuits is too long for short or small transfers ? taking a second to set up a 100 Gigabit/sec link in order to transfer a small file does not make sense. This project is building an integrated campus network where small data transfers (megabytes or gigabytes) ride conventional networks and big data transfers (terabytes or petabytes) ride directly on optical circuits. The project is building PROnet, a campus network at the University of Texas, Dallas, which provides the lowest possible network latency (signal propagation only), scalability to 100Gbps and beyond, and equipment having low power consumption and complexity. A user-friendly interface will be developed and deployed for the network inexperienced researcher to request the provisioning of as needed optical. A PROnet controller will be developed for the scheduling and automatic provisioning of optical circuits, which will shorten the circuit reservation procedure time significantly by removing human intervention from the entire process. For inter-domain operation, the open platform OSCARS will be extended to work with PROnet. With this OSCARS extension, provisioning of hybrid (optical and virtual) circuits spanning across multiple (optical and non-optical) domains will be a reality. The software will support secure use of the network via InCommon identities.
