Instrumentation and Measurement Working Group meeting at GEC6:

Wednesday, November 18, 9am - 11am

Welcome and introduction:

Paul Barford, University of Wisconsin, WG Co-Chair

Approximately 33 attendees.

Initial view of I&M vision, requirements, strawman, and WG Objectives for Spiral 2:

Paul Barford, University of Wisconsin, WG Co-Chair slides

  • brief history of GENI I&M
  • vision for GENI I&M
  • 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


measure details of GENI behavior with high precision and accuracy no impact on experiments ubiquitous extensible large capacity high availability resilient 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


link sensors - deployed on network links via taps, provide basic link signals node sensors - deployed on all systems , provide basic utilization/state/configuration data time sensors - deployed at all sites, provide fine-grained, synchronized timestamps

collection and synthesis

programmable systems connected to sensors transform basic signals into data suitable for more stnadard analysis transformations can be more sophisticated x x

data archieve

high capacity data repositroy deployed data catalog

security and access control

only accessible by authorized users different views depending on authorization level secure private some mechanisms defined by CF

objectives of I&M WG

create an architecture for measuremnt that ensables GENI goals to be achieved, document and refine facilitate dialog and coordination between tams focussed on I&M identify key challenges in I&M that could otherwise inhibit the infrastructure solicit feedback from users mailing list, wiki, GECs

Short presentations by Spiral 2 projects involving instrumentation and measurement design and prototyping, including: 1) title and team, 2) Spiral 2 objectives, 3) challenges, and 4) proposed approach (approx 7min)
