GENI Instrumentation and Measurement Working Group

Charter

Scope: Discuss, develop and build consensus around the architectural framework for the instrumentation and measurement infrastructure that will be deployed and used in GENI.

Chairs: Paul Barford Bruce Maggs

GPO System Engineer: Harry Mussman

Mail list: mail to inst-meas-wg@geni.net / subscribe / mailman archive

Objectives:

Create an architecture for measurement that enables GENI goals to be achieved, document and refine
Facilitate dialog and coordination between teams focused on I&M
Identify key challenges in I&M that could otherwise inhibit the infrastructure
Solicit feedback from users
Communicate via mailing list, wiki, GECs

Meeting Minutes and Presentations


Work-in-Progress

GENI I&M Capabilities Catalog

A v0.1 DRAFT has been completed by the GPO, and includes overview slides, a spreadsheet of the catalog, and drawings from referenced projects.

This document reviews each current GENI I&M project, and other selected projects, and lists:

Architecture components addressed or implemented
Implementations in GENI, or elsewhere
Uses in GENI, or elsewhere

The purpose is to:

Identify projects that can best contribute to architecture topics
Identify projects that can implement enhanced GENI capabilities in Spiral 2

GENI I&M Architecture Document

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

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)

This DRAFT has a revised outline:

A third DRAFT (v1.0) is in preparation, with input from the WG.

The community is invited to help prepare and review this draft, and provide comments, additions or changes to the Inst&Meas WG SE, Harry Mussman, at hmussman@bbn.com

Priority topics

The following priority topics were identified at the 2nd I&M workshop, and teams of attendees (and some non-attendees) were identified for each topic to discuss it, and write a text summary for review by the WG.

Topic 1 GENI I&M Use Cases

Topic 2 GENI I&M Services

Topic 3 GENI I&M Resources

Topic 4 GENI I&M Measurement Plane and Interfaces

Topic 5 GENI I&M Interfaces and Protocols (APIs): Manage Services

Topic 6 GENI I&M Interfaces and Protocols (APIs): Data Flows and Data File Transfers

Topic 7 GENI I&M Interfaces and Protocols (APIs): Registration and Discovery of Services with Available Measurement Data

Topic 8 GENI I&M Interfaces and Protocols (APIs): GUIs

Topic 9 GENI Measurement Data Schema

Task: Define GENI I&M Services?

Task: Define GENI Interfaces, Protocols and Schema for Measurement Data?

Task: Define GENI I&M Use Cases?

Task: Define GENI Measurement Plane?


Available GENI I&M Tools

The GENI I&M Capabilities Catalog identified several available tools at the start of Spiral 2. Throughout Spiral 2, these tools have continued to mature, and several were ready for use by the beginning of Spiral 3.

Tutorials covering four available tools were given at the 3rd I&M Workshop at GEC9:

INSTOOLS: Instrumenting and Monitoring Slices

Jim Griffioen and Hussamuddin Nasir (University of Kentucky) Slides

OML Tutorial

Jolyon White (NICTA) Slides

perfSONAR Tutorial

Martin Swany and Guilherme Fernandes (University of Delaware) Tutorial

OnTimeMeasure Tutorial

Prasad Calyam (The Ohio State University) Slides

The community is invited to start using these tools, and provide comments, additions or changes to their developers.


References

  • Vision for GENI I&M (per Barford on 11/18/09)
    instrumentation and measurement systems provide broad data gathering, analysis and archieval capability
    sufficient for scientific mission
    sufficient for operations
    key for success of the infrastructure
  • Requirementsfor for GENI I&M (initial view) (per Barford on 11/18/09)
    measure details of GENI behavior with high precision and accuracy
    no impact on experiments
    ubiquitous
    extensible
    large capacity
    high availability
    resilient
    strong access control
    tight integration with CFs
  • Conceptual strawman (per Barford on 11/18/09)
    instrumentation - taps in the metwork and systems that provide basic signals
    collection and synthesis - programmable systems that collect, combine and transform basic signals
    archieve - measurement data index and repository
  • DatCat project, that provides a catalog that indexes Internet measurement data, which you can then find, annotate, and cite.
