Idea

• 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• 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

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

CRONCyber-infrastructure for Reconfigurable Optical Networks

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

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)

FederationGENI 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

CRON urn:Short Name: cron.loni.orgFull 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.orgurn: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

LONI supports Vlans 2000 – 4000 for DCN connections

Current defined Vlans2096, 2097, 3440, 3441 EAGER Project

CRON has a direct Layer-2 connection to IONOnce the project defines Vlans for Proto-GENI we

plan to limit the Vlan range for CRON to a small subset

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 needDCN bandwidth is shared between multiple projects.

• Users that cause problems will have OSCARS login suspended
