• Status of functions and features planned for Spiral 3– On track with plan

• At GEC 10 demo:– IMF’s PSM and MH communicated using pS query

• GEC8 demo and before – used proprietary (arbitrary) XML-RPC interaction

– MH integrated new pS service “IMFRealTime” (based on “skeleton” service of pS) – field pS queries, trigger measurement

– Code released on wiki• Now:

– “IMFRealTime” updated to subsume true MP+MA (with database) functions: more versatile pS queries

– pS queries can be sent by clients without going through IMF– All measurements, triggered, scheduled, in database

• Next:– Integrate proposed MDOD– Restore XML-RPC pathway– OMF for control pathway, ORCA integration (later)

S/W: IMF client-side code (Java) (in IMF VM image (SILO) or standalone) – as beforeBox: GENI Slice or anything connected toCommodity network OR mgmt network

Not in GEC10 cut

S/W: pubsub_for_perfsonar.tar.gz in GEC10Box: IMF Agent of aggregate (could be physically remote)

S/W: Measurement handler (with IMFRealTime service code: mh.tar.gz + perfsonar_imf_realtime.tar.gz in GEC10)Box: Measurement Agent of aggregate, typically sitting next to optical switch or other substrate (could be ERM box)

NEW: pS request (SOAP)

NEW: pS codepS query client

• Connectivity planned for Spiral 3– Continue with BEN-ORCA connectivity– Integrate into LEARN

• Tools: planned for Spiral 4– Allow experimenter to see measurement/actuation capabilities of

substrate as resources measurement/actuation capabilities of resources

• Must include realtime capability quantification• Conform to MDOD - actuation?

– Allow experimenter to specify inclusion of such resources in slice– Allow experimenter to “hook up” measurement capabilities with

protocols inside stack (pS or XML-RPC), similarly actuation capabilities (OMF or XML-RPC)

– Allow IMF-controllable actuation resource to be viewable and controllable through an OMF experiment

• Experiments planned for Spiral 3– No outside researcher experimenters as of now– No multiple aggregates as of now (but possibly after I&M

architecture emerges)

• Integrate IMF capabilities into LEARN testbed – Already collaborating with LEARN

• Interfacing / using IMF in CentMesh (outdoor wireless mesh testbed at NCSU) - started
