Biography

Dr. Payman Samadi
Post-doctoral Research Scientist
Columbia University

Payman Samadi received his Ph.D. degree in photonics and telecommunications from McGill University, Montreal, QC, Canada in 2012.  He was a product manager at Optiwave Systems Inc. leading optical system simulation software tools.  He is currently a post-doctoral research scientist at the lightwave research laboratories of Columbia University, New York, NY, USA.  His research interests include network architecture, software-defined networking and optical interconnects for applications in data centers and distributed computing.

Abstract

The rise of cloud computing and big data has enormously increased the deployment of data centers.  Majority of the data centers are small to mid-sized, generally located in metro-scale distances and are actively communicating for services such as data replication, Virtual Machine (VM) migration, backup, load balancing or fault/disaster recovery.  This work presents a software-defined optical network to provide on-demand, bandwidth-selective and high throughout inter data center connectivity in metro-scale distances.

Teachers in Industry Opportunity

Teachers in Industry is the innovative business-education partnership that places experienced classroom teachers in your workforce during the summer. Businesses gain from the professionalism and expertise of a science, technology, engineering or math (STEM) teacher. Teachers take their real-world industry experience back into the classroom to more effectively prepare students to enter the future workforce. The Teachers in Industry program is the best long term investment in the development of future scientists, technologists, engineers and mathematicians essential to the 21st century workforce.
Teachers in Industry, formerly known as the MASTER-IP Program, was established in 2009 by the University of Arizona College of Education, Tucson Values Teachers, Science Foundation Arizona and Raytheon Missile Systems. Continue reading

IAB RESEARCH CORNER UPDATE

A team of students from the University of Arizona, Columbia University, the University of California, Los Angeles, the University of Southern California, and Cornell University completed a test bed insertion and demonstration of the CIAN Box in the TOAN test bed during the May NSF site review. The configuration is shown schematically in Figure 1.

Figure 1. Credit: CIAN Box Team. Schematic of CIAN Box test bed insertion and associated networking architecture. DE = Distance Emulation, CDC = Colorless, Directionless, Contentionless, WSS = Wavelength Selectable Switch, DLI = Delay Line Interferometer, OSNR = Optical Signal-to-Noise Ratio, TiSER = Time Stretched Enhanced Recorder – used for quality of service measurement, OFDM = Orthogonal Frequency-Division Multiplexing, DP-QPSK = Dual-Polarization Quadrature Phase Shift Keying, OOK = On/Off Keyed

The distance emulators are designed to implement a variety of network impairments as shown in Figure 2.  Various impairments, singly and in combination, were added to the signals and the quality of service (QOS) was monitored.  If the QOS fell below the desired level, the signal was switched onto a different channel with a potentially different encoding scheme.  After many late nights and long weekends the assembled system is shown in Figure 3.  A picture of the implementation team is shown in Figure 4.  Additional information can be found on the CIAN website.
