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

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)

Experimental Setup at Columbia University
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

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:– NetFPGA summer camp 2010 (Aug 8-13) – OpenFlow tutorial 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

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.

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.
