     14
     15 brief history of GENI I&M
     16
     17 vision  for GENI I&M
     18
     19 instrumentation and measurement systems provide broad data gathering, analysis and archieval capability
     20  sufficient for scientific mission
     21  sufficient for operations
     22    key for success of the infrastructure
     23 
     24 requirements
     25  measure details of GENI behavior with high precision and accuracy
     26  no impact on experiments
     27  ubiquitous
     28  extensible
     29  large capacity
     30  high availability
     31  resilient
     32  strong access control
     33  tight integration with CFs
     34 
     35conceptual strawman
     36  instrumentation - taps in the metwork and systems that provide basic signals
     37  collection and synthesis - programmable systems that collect, combine and transform basic signals
     38  archieve - measurement data index and repository
     39 
     40instrumentation
     41  link sensors - deployed on network links via taps, provide basic link signals
     42  node sensors - deployed on all systems , provide basic utilization/state/configuration data
     43  time sensors - deployed at all sites, provide fine-grained, synchronized timestamps
     44 
     45collection and synthesis
     46  programmable systems connected to sensors
     47  transform basic signals into data suitable for more stnadard analysis
     48  transformations can be more sophisticated

     65objectives of I&M WG
     66  create an architecture for measuremnt that ensables GENI goals to be achieved, document and refine
     67  facilitate dialog and coordination between tams focussed on I&M
     68  identify key challenges in I&M that could otherwise inhibit the infrastructure
     69  solicit feedback from users
