Department of Computer Science and Center for Computation & Technology Federating CRON with ProtoGENI Seung-Jong (Jay) Park Assistant Professor Computer Science and Center for Computation & Technology Louisiana State University July 22, 2010
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 Cisco/UltraLight wave EnLIGHTen ed wave (Cisco/NLR) LONI wave CHI HOU DAL TUL KAN PIT WDC OGD BOI CLE POR DEN SVL SEA Baton Rouge Raleigh To Asia To CanadaTo Europe L.A. San Diego CAVE wave Chicago
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 CRON Cyber-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)
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” NSF parts of GENI Backbone #1 Backbone #2 Wireless #1 Wireless #2 Access #1 Corporate GENI suites Other-Nation Projects Other-Nation Projects Compute Cluster #2 Compute Cluster #1 My experiment runs across the evolving GENI federation. My GENI Slice This approach looks remarkably familiar...
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 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 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
