  1. An Integrated Measurement Framework (IMF) for Enabling GENI Substrate Measurement and Control I. Baldine, K. Bergman, R. Dutta, C. P. Lai, G. Rouskas, A. Wang, M. S. Wang

  2. Experimenter access to measurement • Provides abstraction of substrate measurement capabilities • Physical layer attributes: optical or RF power • Performance parameters: BER, packet loss, CPU usage • Experimenter sees unified interface

  3. Architecture • Measurement plane – represents the measurement functionalities available within an experimenter’s slice • Substrate environment control – Environment of a slice may be manipulated

  4. Architecture Track subscribe requests from consumers; Receive publish events with measurement data or meta-data. Experimenter tools outside slice; In-slice functions for closed feed-back loop; Storage functions to collect and store Allows consumer to subscribe by interest, polls; Translate information substrate and slice topology. Like PSM, but applied to substrate environment control Presents a uniform interface to substrate control and manipulation capabilities Presents a uniform interface to configure and query substrate measurement capabilities.

  5. Use Case Run SILO applications on ORCA-BEN. SILO: Services Integration, controL, and Optimization. • The SILO Measurement Service can access IMF substrates to obtain measurement data or control substrate environment. • MH substrates include Polatis, DTN, and Cisco (future). • SCH substrates may include SOAs, NetFPGAs, programmable attenuators, etc.

  6. Next Steps • Run SILO – IMF for a complete closed-loop feedback control demonstration • Create SCM to mirror measurement capability • Measure – control – monitor • Down the road – better presenting capabilities to experimenter who only consumes • Also examine API for in-slice consumer programmers • Integrate with measurement ontology ?
