Project Summary (1/3) • Measurements are important to experimenters • Some measurements can be made by experimenter code, in or on top of slice, but – • Measurements from substrate are also very important • Experimenter cannot directly measure L1 or close to L1 • Substrates must provide measurement capability, as part of substrate capability • Especially optical substrates – measurement capability and technology is not trivial • Experimenter should be able to request measurement capability when requesting sliver • Access control, accounting etc. issues • Experimenter must be able to consume measurements at any layer (in-slice), online • Consumer is automated protocol, designed by experimenter • Good deal of research in recent years has focused on cross-layer control • Normal consumption at “L8”, offline consumption, must also be enabled • Desirable to integrate actuation in same design • Close the loop of feedback control by reactive protocols • Plan: Build on UMF (GENI ERM project) to provide diverse optical substrate measurements uniformly, use SILO (NSF FIND project) to consume and react in-stack, offer to experimenter through ORCA August 27, 2010

Milestone & QSR Status August 27, 2010
Accomplishments 1: Advancing GENI Spiral 2 Goals (1/2) • IMF addresses the “Instrumentation and Measurements” Spiral 2 Goal of GENI • Creates a framework for a specific measurement flow and utilization pathway • Demonstrates the practicality of using substrate measurements in slice • Even (especially?) when the substrate uses specialized technology • Articulates the connection between measurement (sensing) and actuation • Meaningful to address both in the same conceptual framework • Also addresses the underlying philosophy of integration • Defined multiple modes to rendezvous producer and consumer of measurements • Unified pub-sub approach to realizing these modes • Provides a structure to base further pertinent work on • Access control to measurement data – privilege to consume • Any and all substrates? Only substrates occupied by slice? Logged measurement data as substrate spec? • Year 1 accomplishments can be summed up by considering the GEC8 demo August 27, 2010
Accomplishments 1: Advancing GENI Spiral 2 Goals (2/2) August 27, 2010
Accomplishments 2:Other Project Accomplishments • Attended GECs, demos • Attended and contributed to the I&M working group meetings • Collaborated with LEARN to synchronize substrate measurement effort • Expended effort in understanding perfSONAR • Attended the perfSONAR workshop • Held one-on-one meeting with Martin Swany to discuss possibility of convergence • Jointly with LEARN, evaluated perfSONAR and potential convergence with IMF • Currently making specific plans to introduce GENI and IMF coverage in courses and NCSU, Columbia • Special day-long courses under design at Columbia August 27, 2010
Issues • Initial delay in contract negotiation – GPO handled by delaying first milestone date • Kept to actual presentation at GEC6 • General delay in keeping up with milestones on wiki, and wiki updates • PI acknowledges problem, will do better • Non-standard calendar causing some tension • Funds only till end of September • Initial refusal by admin staff to appoint RA • Also cannot hang on to ARRA money • Contact with GPO financial staff has brought no solution • Currently resolved – will face again next year August 27, 2010
Plans – Rest of Spiral 2 • Complete packaging and release of software, together with complete h/w and demo specs • Complete annual project report August 27, 2010
Plans – Potential Spiral 3 • Stay on track for original goals • Catch up on measurement ontology – in concert with I&M frameworks • Contribute to emerging I&M architectures – integrate IMF as a unique capability • Cross-layer, in-slice, optical substrate • Extend capabilities • Develop suite of software libraries to expand the measurement capabilities of IMF • Increase set of programmable active components for actuation and cross-layer control • Develop ORCA interface further • Allow SILO services and IMF capabilities to be represented in ORCA • Allow ORCA to advertise and provision measurement capabilities as SILO and IMF services • Develop experimenter’s interface • Allow experimenter to specify what layers to cross-layer experiment on • Allow experimenter to load experimental code as SILO service • Allow experimenter to load experimental code as tuning algorithm • Added specific directions • Interface / find convergence point with PerfSONAR, and any other useful architectures • Continue outreach efforts August 27, 2010
