Datacenter Circuit-Switching: This was a joint effort with folks from Carnegie Mellon

SELECTED

RECENT PROJECTS University (CMU), Rice University, and Intel Labs at Pittsburgh in which the fundamental

challenges in building hybrid electrical/optical datacenter networks are explored. We discuss

both the problems that must be addressed to make these interconnects truly useful and the

implications of these challenges on what solutions are likely to be ultimately feasible

through proposing an observe-analyze-act framework. As an outcome of this effort, we

published a paper in SOCC 11.

Opportunity Cost: Lack of inventory at fulfillment centers close to the cities can be very

expensive for Amazon.com especially upon fulfillment of fast-track orders. In this summer

internship project, we investigate a potential solution to this problem through applying a so

called opportunity cost when fulfilling any orders through these fulfillment centers. We

implement and analyze the results of this approach.

HELIOS: This work was done at UC San Diego. We built a fully functional prototype of a

hybrid/electrical optical switch architecture for datacenters using commercial 10GigE

packet switches and MEM-based optical circuit switches. I was involved in designing

scheduling algorithms and developing a centralized topology manager which controls the

routing path of the flows by changes the circuit mapping of circuit switches based on the

traffic information received from switches. This project is developed in C++, Python and

Linux shell scripts and is published in SIGCOMM 10.

VIVALDI: How would TCP look like if it has information about the underlying wireless

channel characteristic (e.g., wireless signal level, mac layer retransmission ratio, etc) at each

time and could use that to adjust its rate? I was working on this project over a summer

internship at Cisco Systems. The idea is to use cross layer optimization to improve the

performance of wireless TCP connections. I was involved in developing a complete

emulation framework to experiment and study the ideas further. This project is done with

C, Python, and Linux bash script.
