  • Real network connections

    • Up to 10,000km of optical fibers

    • Up to 200ms of delay

  • Emulated network connections

    • Less than 100m of optical fibers

    • Up to 200ms of delay


Motivation

Motivation

  • Demands

    • Many users at Physics, Bio, Chemistry, Medical and Mechanical eng. Areas want to use high speed networks

      • 15 NSF EPSCoR proposals from the LA state

      • Hundreds (??) of proposals from the States

  • Facts

    • Only a few optical fibers are available

    • They need to wait until networks are stable and ready to use after they requests to network administration staffs

      • It takes from a few days to weeks

      • It asks more than a few staffs at a few places

CRONCyber-infrastructure for Reconfigurable Optical Networks

  • Goal

    • Bridging the gap between physical networks and large scale scientific research

  • Objectives

    • Developing virtually shared 10Gbps networking and high-end computing resources

    • Enabling large scale scientific experiments to share CRON without mutual interference

Components

Components

  • Switches

    • Data plane: Cisco Nexus 5020 switch consisting 50 X 10GE ports

    • Control plane: Cisco 3560 switch

  • Emulators

    • Hardware Emulators: 4 X Anue 10GE emulators for upto 10Gbps bandwidth

    • Software Emulators: modified NistNet & Dummynet for less than 5Gbps bandwidth

  • Workstations

    • 20 X Sun X4250 servers (two quad cores with 10GE)


Connecting cron with geni

Connecting CRON with GENI

  • Connections

    • Between CRON and LONI

      • 10GE X 2

    • Between LONI and Internet2

      • Internet2 ION (Interoperable On-demand Network) (upto 7GE)

      • LONI 10G to Interent2 (Shared Resource: R&E, CPS/TR, ION)


Federation geni grows by gluing together heterogeneous infrastructure

Goals: avoid technology “lock in,” add new technologies as they mature, and potentially grow quickly by incorporating existing infrastructure into the overall “GENI ecosystem”

How to connect to loni cron

How to Connect to LONI/CRON

  • CRON urn:

    • Short Name: cron.loni.org

    • Full urn: urn:ogf:network:domain=loni.org:node=lsu-dcn:port=0-2-3:link=*

    • The full urn will change by mid August

  • LONI Main urn:

    • Short Name: loni-e1.loni.org

    • urn:ogf:network:domain=loni.org:node=loni-dcn-e1:port=0-9-3:link=*

  • LONI Test urn:

    • Short Name: test1.btr.loni.org


Ion dcn vlans

ION/DCN Vlans

  • LONI supports Vlans 2000 – 4000 for DCN connections

  • Current defined Vlans

    • 2096, 2097, 3440, 3441 EAGER Project

  • CRON has a direct Layer-2 connection to ION

    • Once the project defines Vlans for Proto-GENI we plan to limit the Vlan range for CRON to a small subset


Bandwidth

Bandwidth

  • LONI will change the bandwidth available for ION/DCN circuits.

    • The Internet2 connection is shared between R&E, CPS/TR, and ION.

      • R&E traffic needs will be given priority on LONI network during semesters.

      • ION and CPS/TR traffic will be determined by user needs.

      • Our current max reservation is 7G.

  • Only reserve what you need

    • DCN bandwidth is shared between multiple projects.

      • Users that cause problems will have OSCARS login suspended
