4.3) I&M Use Cases for Infrastructure Measurement, and Support for Operators

4.3.1) Goals

Provide a concise but complete definition of I&M Use Cases for Infrastructure Measurement

Include the support that should be available to operators

Update the GENI I&M Architecture document:

Sec. 3.1. I&M Use cases for Experimenters
Sec. 4.3.1 Type 1 I&M Service: Service Contained within a Slice

Use as guidance in the design of GENI I&M tools, particularly for the GEMINI and GIMI projects

4.3.2) Issues

1) Can an Operator (e.g., GMOC) ever see MD owned by an Experimenter, e.g., to verify acceptable use of GENI resources or to troubleshoot problems in GENI infrastructure? If so, how?

4.3.2) Team

LEAD Martin Swany (Indiana U) Eric Boyd (Internet2) Jason Zurawski (Internet2) Prasad Calyam (Ohio Super Center) Chris Small (Indiana U); Ilia Baldine, for ExoGENI racks (RENCI); ?, for InstaGENI racks (HP); ?, for GMOC
Harry Mussman (GPO)

4.2.3) Meetings

Review with operators at GEC13

1) Definition of topic:

a) Delineate what infrastructure monitoring is and is not covered by this approach.

1) Yes: monitoring of clusters/racks
2) Yes: passive measurements of transport switches, etc.
3) Yes: active measurements of IP networks, of Layer 2 and OpenFlow paths

b) Nominal infrastructure measurement process:

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

c) What support must be provided for Operator? how?

2) Who: LEAD Martin Swany (Indiana U); Eric Boyd (Internet2); Jason Zurawski (Internet2); Prasad Calyam (Ohio Super Center); Chris Small (Indiana U); Ilia Baldine, for ExoGENI racks (RENCI); ?, for InstaGENI racks (HP); ?, for GMOC
