Company Proprietary Information 2/7/2013 10 Network Infrastructure Program Improvement Goals (CC-NIE Area #1) network upgrades within a campus network to support a wide range of science data flows (including large files, distributed data, sensor networks, and real-time data sources) Brocade Routers support SDN and Legacy Protocols (BGP, OSPF, MPLS, etc.) concurrently in existing hardware/software. Allows Science applications to integrate with existing Campus Infrastructure. re-architecting a campus network to support large science data flows, for example by designing and building a "scienceDMZ" (see http://fasterdata.es.net/fasterdata/sciencedmz/ for more information on the "science DMZ" approach) See Subsequent Slide on Creating a Science-DMZ and how Brocade Solutions Meet Requirements Network connection upgrade for the campus connection to a regional optical exchange or point-of-presence that connects to Internet2 or National Lambda Rail. Brocade Routers are in use at Internet 2 and a Number of Regional RENs/Exchanges as well as Higher Ed Institutions as Border Router connections to those POPs. © 2012 Brocade Communications Systems, Inc.
