4.2) I&M Use Cases for Experiments, and Support for Experimenters

4.2.1) Goals

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

Include the support that should be available to experimenters, i.e., on-line instructions, examples and help desks.

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

4.2.2) 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?

4.2.3) Team

CO-LEAD Jim Griffioen (U Kentucky)
CO-LEAD Mike Zink (UMass Amherst)
Max Ott (NICTA)
Prasad Calyam (Ohio Super Center)
Harry Mussman (GPO)

4.2.4) Meetings

Review with experimenters at GEC13

4.2.5) Vision

From Sec. 2 of the GENI I&M Architecture document:

To conduct useful and repeatable experiments, GENI experimenters require extensive and reliable instrumentation and measurement capabilities to gather, analyze, present and archive Measurement Data (MD).

Remove the burden on researcher to become a system and network measurement infrastructure expert so that researcher can better focus on the science in the experiments

Want to work towards Max Ott's vision for experiment support


4.2.6) Baseline experiment use case


1) Setup and run experiment using Experiment Control Tools and Experiment Orchestration Service
1b) Include resources and software for instrumentation and measurement services in the slice

2) Setup and run measurement services within slice, using persistent services as necessary.
2b) Option: get measurement data from persistent MP.

3) Gather MD into MAP service, to analyze and.or visualize, during or after experiment; formulate MDOD.

4) Archive MD with MDOD.

5) Share archived MD with others, per policy included within MDOD.

6) Pull MD out of archive, to analyze and/or visualize.


4.2.7) Extended experiment use cases

Extended experiment use cases:

1) WiMAX (or other wireless) measurements
1b) Where MC may be disconnected from MPs from time to time.

2) LEARN/BEN layer 0,1 or 2 measurements
2b) Which may drive other functions in the experiment, i.e., adjust protocol parameters
2c) Where short delays are essential

3) Sensor network (radars, power monitors)
3b) Where measurements are at the heart of the experiment

4) Measure DiCloud workflow

4.2.8) Baseline slice measurements

A typical experimenter's slice includes several nodes or hosts, with connecting links. Baseline slice measurements include a set of measurements for each node or host.

From INSTOOLS, this is: baseline measurements of each node (host)

4.2.9) Support for experimenters

1) What support must be provided for Experimenters?
1b) On-line instructions
1c) Examples
1d) Help desks
1e) How?
