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

加州理工学院的高性能光学集成网络（CHOPIN）提供了最先进的网络技术，加州理工学院校园作为一个单一的概念，支持几个领先的研究小组。CHOPIN在校园内部署了支持软件定义网络（SDN）的交换机，以及加州理工学院和CENIC之间的100 Gbps链路，支持直接连接到加州OpenFlow测试床网络（COTN），连接到Internet 2高级第2层服务（AL 2S）网络，以及其他主要的研究和教育网络。通过这种方式，CHOPIN支持网络领域的前沿研究和开发活动，以及基于高吞吐量计算（HTC）的应用和使用大数据量和速度的研究。设计中集成的ScienceDMZ概念允许在同一底层基础设施上支持校园通用网络和HTC应用的统一、灵活且高性能的系统。新的100 G功能为集成路由高性能服务铺平了道路，例如CENIC HPR-L3和Internet 2高级第3层服务。上行链路由100 G和40 G链路补充，连接到一组支持OpenFlow的交换机，连接到几个主要研究小组。基础设施的改进和利用的软件和方法使加州理工学院的所有校园受益，并明确涉及大数据和高通量研究的小组，如高能物理学、天文学（LIGO，LSST）、地震学、大地测量地球卫星观测和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.
