GENI Instrumentation and Measurements Architecture, Version 0.1

An effort is underway to define and document the GENI Instrumentation and Measurements Architecture.

Plan:
+ Completed by GEC7: v0.1 DRAFT, by GPO
+ Completed by GEC8: v0.5 DRAFT, by GPO, with revised outline and contributions after 2nd workshop
+ In preparation: v1.0 DRAFT, including contributions from WG

A first DRAFT (v0.1) was completed by the GPO: GENI I&M Architecture (Document ID: GENI-SE-IM-ARCH-0.1, Date: March 8, 2010)
This DRAFT includes proposed I&M services and a proposed configuration

Document outline:

  1. Document Scope
  2. Introduction
  3. Definition and configuration of I&M services
  4. Interfaces, protocols and schema for Measurement Data (MD)
  5. Ownership of MD and privacy of owners
  6. Interfaces, protocols and APIs for using I&M services
  7. Basic GENI I&M use cases
  8. MD transport via the GENI Measurement Plane
  9. Discovery, authorization, assignment and binding of GENI I&M services
  10. Measurement Orchestration (MO) service
  11. Measurement Point (MP)
  12. Time-stamping MD
  13. Measurement Collection (MC) service
  14. Measurement Analysis and Presentation (MAP) service
  15. Measurement Data Archive (MDA) service
  16. Additional GENI I&M use cases

This document was reviewed at the Inst&Meas WG meeting at GEC7: slides

A second DRAFT (v0.5) was completed by the GPO, with input from the 2nd I&M Workshop: GENI I&M Architecture (Document ID: GENI-SE-IM-ARCH-0.5, Date: July 22, 2010)
