What is CRON?Experimental Networking Testbed for 10Gbps High Speed Networks

Motivation of CRON Challenges of experimentation over 10Gpbs production networks Scarce and expensive resources Limited access for network researchers Interference to other production level traffic uncontrollable networking environments

CRON InfrastructureGoal : Bridging the gap between physical Networks and large scale scientific researchObjectives : (1) Developing virtually shared 10Gbps networking and high-end computing resources and (2) Enabling large scale scientific experiments to share CRON without mutual interference

Introduction of CRON

Research Impact of CRONNext generation networking and computing researchDistributed computing for large scale computational sciences(Physics, fluid dynamics, bioinformatics, etc.), Remote visualization

Vertical Federation CRON with OnTimeMeasure@OSU

Integrating the OnTimeMeasure sliver on CRON experiment slice

Real time data diagnosis from CRON experiment slice

Experimental Results(Y-shape topology)Aggregated throughput between flows reaching 9Gbps

Federation of CRON with GENI

Horizontal Federation CRON with ProtoGENI@BBNEmulab-based Component Manager & Slice AuthorityReceiving user credentials Register a slice at the Clearinghouse@Utah

Resource reservation between component managersCreating slivers Exchanging RSpec

Internet2 connection between CRON and ProtoGENI@BBNCreating a vlan with ION service of Internet2
