GENI Instrumentation and Measurement Working Group


Scope: Discuss, develop and build consensus around the architectural framework for the instrumentation and measurement infrastructure that will be deployed and used in GENI.

Chairs: Paul Barford Bruce Maggs

GPO System Engineer: Harry Mussman

Mail list: mail to / subscribe / mailman archive


Create an architecture for measurement that ensables GENI goals to be achieved, document and refine
Facilitate dialog and coordination between teams focussed on I&M
Identify key challenges in I&M that could otherwise inhibit the infrastructure
Solicit feedback from users
Communicate via mailing list, wiki, GECs


Meeting Minutes and Presentations


  • Common schema for measurement data example: see recent DatCat project, that provides a catalog that indexes Internet measurement data, which you can then find, annotate, and cite.

  • Common mechanism for accessing data

  • Gather in one document the measurements desired for experiments by other projects, i.e., target problems


  • Vision for GENI I&M (initial view)
    instrumentation and measurement systems provide broad data gathering, analysis and archieval capability
    sufficient for scientific mission
    sufficient for operations
    key for success of the infrastructure
  • Requirementsfor for GENI I&M (initial view)
    measure details of GENI behavior with high precision and accuracy
    no impact on experiments
    large capacity
    high availability
    strong access control
    tight integration with CFs
  • Conceptual strawman
    instrumentation - taps in the metwork and systems that provide basic signals
    collection and synthesis - programmable systems that collect, combine and transform basic signals
    archieve - measurement data index and repository
