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

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.
