== Instrumentation & Measurement Working Session == Wed, 0830-1200 Organizer: Harry Mussman, GPO Description: This session will review the status of current I&M design and prototyping efforts, including the I&M services that have been deployed in GENI and the I&M software that is now available to experimenters and operators. Various I&M use cases will then be illustrated using example experiments. [[PageOutline]] = Instrumentation and Measurement (I&M) Working Session = Wednesday, November 2, 2011, 8:3oam - 12noon [[BR]] Room: [[BR]] Session Leader: Harry Mussman, (GPO, Raytheon BBN Technologies) [[BR]] == Description == This session will review the GENI I&M design and prototyping projects planned for Spiral 4 (this year), including the two large Solicitation 3 I&M D&P projects and those continuing projects from Solicitation 2. Then, it will define and discuss the priority topics that must be resolved between now and GEC13. [[BR]] == Summary == == Agenda == This is a tentative agenda, which may change.

Currently we have to deal with several different users accounts, authentication schemes, object granularity, etc. BTW, we have integrated INSTOOLS with the CNRI workspace model, but again, they have yet another set of user accounts and passwords to deal with. If we could start moving toward some standards in this area, that would be very helpful.

[[BR]] ==== 4.8) Extensions ==== Use MDA as a full Experiment Repository to archive all experiment objects, including: meas data; software; topology/rspec? [[BR]] Use various versions of MDOD to negotiate transfer of data object, e.g., like GENI resource assignment; use versions of MDOD to like rspec advertisement, request, amnifest. [[BR]] Use MDOD with descriptor and holder/transaction records for "object assignment record"; use similar structure in GENI resource assignment to give "resource usage record" [[BR]] === Adjourn === 3:00pm [[BR]] == Background Reading == [http://groups.geni.net/geni/wiki/GeniInstMeas I&M integration wiki][[BR]] [http://groups.geni.net/geni/wiki/GENIIandMCAPCAT GENI I&M Capabilities Catalog][[BR]] [http://groups.geni.net/geni/wiki/GeniInstrumentationandMeasurementsArchitecture GENI I&M Architecture document][[BR]]
