CC-NIE Networking Infrastructure: Caltech's High-performance OPtical Integrated Network (CHOPIN)

加州理工学院高性能光集成网络（CHOPIN）为加州理工学院校园提供最先进的网络技术，作为一个单一的概念，支持几个领先的研究小组。CHOPIN在校园内部署了软件定义网络（SDN）功能的交换机，以及加州理工学院和CENIC之间的100Gbps链路，支持直接连接到加州OpenFlow测试平台网络（COTN），连接到Internet2高级第二层服务（AL2S）网络，以及其他主要的研究和教育网络。通过这种方式，肖邦支持网络领域的前沿研发活动，以及基于高通量计算（HTC）的应用和使用大数据量和速度的研究。将ScienceDMZ概念集成到设计中，可以实现统一、灵活、高性能的系统，在相同的底层基础设施上支持校园通用网络和HTC应用程序。新的100G功能也为与路由高性能服务（如CENIC HPR-L3和Internet2高级第三层服务）的集成铺平了道路。上行链路由100G和40G链路补充，连接到几个主要研究小组的一组OpenFlow功能交换机。基础设施的改善和利用的软件和方法使加州理工学院的所有校园受益，并明确参与大数据和高通量研究的团体，如高能物理，天文学（LIGO， LSST），地震学，大地测量地球卫星观测以及许多其他纯科学和应用科学学科，包括计算机科学和应用数学。

The Caltech High-performance OPtical Integrated Network (CHOPIN) delivers the most advanced networking technologies to the Caltech campus as a single concept in support of several leading research groups. CHOPIN deploys Software-Defined Networking (SDN) capable switches on the campus, as well as a 100Gbps link between Caltech and CENIC, supporting direct connectivity to the California OpenFlow Testbed Network (COTN), a connection to the Internet2 Advanced Layer 2 Services (AL2S) network, as well as other major Research and Education networks. In this way, CHOPIN supports leading edge Research and Development activities in the networking area, as well as high-throughput computing (HTC) based applications and research using large data volumes and velocities.The ScienceDMZ concept integrated into the design allows for a unified, flexible, yet high-performance system supporting both the campus General Purpose Network and HTC applications on the same underlying infrastructure. The new 100G capability paves the way for integration also with routed high performance services such as the CENIC HPR-L3 and Internet2 Advanced Layer 3 Services. The uplink is complemented by 100G and 40G links to a set of OpenFlow capable switches to each of several major research groups.The infrastructure improvements and leveraged software and methods benefit all of the Caltech campus, and explicitly groups involved in Big Data and high-throughput research, such as high energy physics, astronomy (LIGO, LSST), seismology, geodetic Earth satellite observations and many other pure and applied science disciplines, including computer science and applied mathematics.
