  1. Embedded Measurement Framework (ERM)Spiral 2 Year-end Project Review PI: Keren Bergman Students: Michael Wang, Caroline Lai, Cathy Chen Senior Researcher: Dr. Balagangadhar Bathula August 27, 2010

  2. Project Summary • Address the GENI challenge of architectural experimentations across diverse heterogeneous technologies by • Supporting embedded real-time measurements from GENI substrates • Utilize measurement capabilities to enable cross-layer communication and control • Spiral 1: • Evaluated GENI’s capabilities for embedded real-time measurements and cross-layer control • Proposed development of a Unified Measurement Framework (UMF) • Joined Cluster D to integrate UMF into ORCA-BEN • Spiral 2: • Designed and implemented a NetFPGA-based UMF • Demoed UMF in an experimental use-case run at Columbia University • Integrated UMF with Integrated Measurement Framework (IMF) and collaborated on an experimental use-case run at BEN based in North Carolina • Began plan to work with other GENI clusters to expand the reach of UMF August 27, 2010

  3. Milestone & QSR Status August 27, 2010

  4. Accomplishments 1: Advancing GENI Spiral 2 Goals Spiral 2 Goal: Instrumentation & Measurement • Implement NetFPGA-based UMF to support embedded real-time measurements and enable cross-layer communications • Develop measurement handler software for Polatis to measure optical power • Develop XML-RPC code and prototype board to control semiconductor optical amplifier (SOA) • Develop MATLAB script to control variable optical attenuator (VOA) UMF Physical Setup August 27, 2010

  5. Accomplishments 1: Advancing GENI Spiral 2 Goals Spiral 2 Goal: Optical Layer Experimentation • Tested UMF in an experimental use-case performed at Columbia University • VOA1 attenuates power of input light signal • Unprotected lightpath (red line) – power on this lightpath is directly affected by VOA1 • Protected lightpath (green line): • UMF monitors power of input light signal • UMF controls SOA to amplify input signal when power is below a threshold • Receiver setup is used to obtain eye diagrams and BER curves Experimental Setup at Columbia University August 27, 2010

  6. Experimental Results Determining Optimal Power Threshold Eye Diagrams August 27, 2010

  7. Accomplishments 1: Advancing GENI Spiral 2 Goals Spiral 2 Goal: Integration IMF Infrastructure at BEN-RENCI Integrate UMF with IMF in BEN August 27, 2010

  8. Accomplishments 2:Other Project Accomplishments • Participated in the First Workshop on the perfSONAR Network Measurement Infrastructure (July 7-9, 2010 in Arlington, VA) • Highlighted our embedded real-time measurements and cross-layer efforts at the breakout sessions • Discussed potential to use physical layer measurements to deal with disaster management of L1 infrastructure • Collaborated with IMF and LEARN projects to discuss possibilities of: • Integrating optical layer measurement capabilities into perfSONAR • Utilizing measurement capabilities of perfSONAR to support cross-layer communication and optimization • Effort toward expanded platforms for implementing UMF: • NetFPGAsummer camp 2010 (Aug 8-13) • OpenFlowtutorial at GEC8 (July 22) • Began planning opportunities to expand reach of UMF • Committed to house GENI Racks at Columbia University in preparation for Solicitation 3 Enhanced Meso-scale Prototype proposal • Committed to technically working with the selected Solicitation 3 I&M project, specifically collaboration with “GEMINI: a GENI Measurement and Instrumentation Infrastructure” proposal • Collaborated with the NSF ERC-funded Center for Integrated Access Networks (CIAN) and hosted 2 REU students to work on cross-layer related projects August 27, 2010

  9. Issues • By end of spiral 2, enabled embedded real-time measurement and cross-layer communication and control in ORCA-BEN. • Expand of ERM capabilities into the other GENI clusters challenged by multiple I&M platforms and efforts. • Clear path for broadening insertion of ERM/Cross-layer in GENI following Solicitation 3 proposals selection. • In the meantime, we have had numerous technical discussions with multiple groups and projects, understand the paths toward expanding UMF across GENI. August 27, 2010

  10. Plans • Spiral 2 (remaining work) • Milestone S2.f • Begin plan to integrate the UMF with infrastructures in other GENI clusters • Spiral 3 (tentative next steps) • Design and develop a more universally deployable version of UMF consisting of: • Suite of software and NetFPGA to expand optical layer measurement capabilities • Set of active optical components (SOAs, VOAs, etc) to enable cross-layer control • Deploy UMF within multiple infrastructures in other GENI clusters • Collaborate with the selected Solicitation 3 efforts • instrumentation and measurement proposal • enhanced meso-scale prototype proposal (GENI Rack) to expand the optical layer measurement and cross-layer optimization capabilities of UMF.
