Instrumentation and Measurement (I&M) Working Session

Thursday, March 17, 2011, 1:00pm - 4:00pm
Room: Bahia 2
Session Leader: Harry Mussman, (GPO, Raytheon BBN Technologies)

Description

This session will review three key instrumentation and measurement (I&M) topics still under study by the GENI I&M community, and present the status of a prototype Measurement Data Archive (MDA) service.

Each topic will be reviewed by a member of the community, and then opened for discussion and a determination of the next steps.

5) Current I&M Design and Prototyping Efforts

3:45pm

I&M services for Experimenters, including:

Instrumentation Tools (for use with protoGENI)
OMF/OML
LAMP (uses perfSONAR technology, for use with protoGENI)
OnTimeMeasure (for use with protoGENI or PlanetLab)

I&M services for monitoring infrastructure, including:

Measurement System, for packet capture
Shadownet, for router monitoring
Scalable Sensing Service

Measurement Data Archive (MDA) service

First prototype by CNRI, including User Workspace (UW) service and Digital Object Archive (DOA) service

Management of an I&M service, from Measurement Orchestration (MO) service:

First prototype by IMF and ERM projects, following OMF approach

Measurement Data Objects, and Descriptors (“metadata”):

Defining common data model, then schemas
First prototype software by ?

Measurement traffic flows, proxies/mechanisms) to reach servers in private address space

First prototype of ssh access by ORCA project

How can we build a guide?

6) I&M Service Deployments

3:50pm

Current I&M services for Experimenters, including:

Instrumentation Tools (for use with protoGENI)
OMF/OML
LAMP (uses perfSONAR technology, for use with protoGENI)
OnTimeMeasure (for use with protoGENI or PlanetLab)

Introduce I&M services for monitoring infrastructure, including:

perfSONAR components, with Measurement Information (MI) service, and first use of Measurement Data Object Descriptors (MDOD’s)? Who?
Measurement System for packet capture?
Scalable Sensing Service?

Introduce Measurement Data Archive (MDA) service:

Include User Workspace (UW) service
Include Digital Object Archive (DOA) service
Who are first users?
Are there other uses, e.g., software downloads?
When ready to support Researchers?
