Sponsored by the National Science Foundation 2 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

Sponsored by the National Science Foundation 6 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

Sponsored by the National Science Foundation 8 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

Sponsored by the National Science Foundation 9 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

Sponsored by the National Science Foundation 10 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

Sponsored by the National Science Foundation 11 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
