[wiki:InstMeasTopic_4.3UseCasesInfrastructure  Work in Progress]  [[BR]] 

1)  Definition of topic:  [[BR]]

a)  Delineate what infrastructure monitoring is and is not covered by this approach.  [[BR]]
  1)  Yes:  monitoring of clusters/racks [[BR]]
  2)  Yes:  passive measurements of transport switches, etc.  [[BR]]
  3)  Yes:  active measurements of IP networks, of Layer 2 and OpenFlow paths [[BR]]

b)  Nominal infrastructure measurement process:  [[BR]]
  1)  Setup persistent or on-demand infrastructure measurement slice.  [[BR]]
  2)  Make passive measurements or make active measurements.  [[BR]]
  3)  Gather MD, and observe as it is gathered;  formulate MDOD.  [[BR]]
  4)  Store MD in collector, describe with MDOD, and register MDOD so that MD can be shared.  [[BR]]
  5)  Typically share MD with Aggregate Operator, GMOC and/or Experimenters, per policy written into MDOD.  [[BR]]
  6)  Pull MD out of collector, analyze and visualize.  [[BR]]
  7)  Archive MD with MDOD.  [[BR]]
  8)  Share archived MD with others, per policy included within MDOD.  [[BR]]
  9)  Pull MD out of archive, to analyze and/or visualize.   [[BR]]

c)  What support must be provided for Operator?  how?  [[BR]]
