Christopher Small – Principal Investigator
Matthew Davy – Co-Principal Investigator
Dave Jent – Co-Principal Investigator


  • "Tango GENI" demonstration of initial integration with AM and other campuses
  • Expansion of IU deployment with NetGear switch and additional HP 5406s
  • Measurement Manager additional features deployed and demonstrated at GEC10
  • Outreach effort at workshops at Internet2 Joint Techs and APRICOT-APAN conferences
  • Began work on Loadbalancer application with Clemson
  • Production Operational Support

Major Accomplishments


Initial integration with AM and other campuses: We deployed a Expedient and Opt-In manager instance connected to the IU Flowvisor. This deployment was successfully used as part of the GENI for Everyone demo. The demonstration showed that a rather complex OpenFlow topology (3 Openflow enabled switches over 2 campuses) could be utilized for external experiments. There were issues with slice creation on the MyPLC nodes in Bloomington because of issues with the nodemanager code crashing on the Planetlab hosts but this was not realted to the core OpenFlow deployment.


Measurement Manager: The Measurement Manager was originally deployed and demonstrated at GEC9. This software capture information about the state of the OpenFlow infrastructure including topology, utilization and configuration of each OpenFlow aggregate. It also captures information thorough the FlowVisor API about the configuration and use of each slice. The collected information can be used by the experimenter, GENI operator or the aggregate owner to monitor and capture information about the experiments and the state of the infrastructure.

For GEC10 we demistrated additional monitoring

Currently data is being collected from the IU, National Lambda Rail and Internet2 OpenFlow networks

More information about the Measurement Manager is at: Measurement Manager

Currently a number of Measurement Manager output formats are used to drive data collection. The Measurement Manager generates configuration for measurement, monitoring and collection of topology information. Some of the live data from the GENI OpenFlow infrastructure is linked below.
