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

没有高性能网络，大数据和高性能计算的价值非常有限。人们早就认识到，最高性能的数据传输应该直接在光电路上运行，而不需要以太网交换或IP路由。这种直接分层避免了与交换相关的分组丢失，并提供了经济高效的服务。现在存在允许动态建立单应用光路的光学设备。然而，建立光路所需的时间对于短或小的传输来说太长了吗？为了传输一个小文件，花一秒钟建立一条100千兆位/秒的链路是没有意义的。该项目正在建设一个综合园区网络，其中小数据传输(MB或GB)使用传统网络，而大数据传输(TB或PB)直接使用光电路。该项目正在建设达拉斯得克萨斯大学的校园网络PROnet，该网络提供尽可能低的网络延迟(仅限信号传播)、可扩展到100Gbps及以上，以及具有低功耗和复杂性的设备。将为网络经验不足的研究人员开发和部署一个用户友好的界面，以根据需要请求提供光纤。将开发一个PROnet控制器用于光线路的调度和自动配置，通过从整个过程中消除人工干预，将大大缩短线路预订过程的时间。对于跨域运营，开放平台奥斯卡将扩展到与PROnet合作。有了这一奥斯卡奖扩展，跨越多个(光和非光)域的混合(光和虚拟)电路的配置将成为现实。该软件将通过不常见的身份支持网络的安全使用。

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.
