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
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
