CESG Seminar: Codes for Distributed Storage Systems: Design, Analysis, and Implementation

January 29, 2016 @ 4:00 pm - 5:00 pm

Dr. Alex Sprintson

Room 236C WEB

Abstract: This talk will provide an overview of our recent research efforts on the design, analysis, and implementation of efficient and secure codes for distributed storage systems. First, we discuss constructions of weakly secure codes that aim to hide information about individual packets as well as small groups of packets from an eavesdropper. Weakly secure codes do not use random keys, and, as a result, have better performance and lower overhead than the traditional schemes.

Next, we discuss the design and analysis of codes of distributed storage codes with certain locality constraints. Inspired from the notion of unequal error protection, we are focus on unequal locality codes, in which, different subsets of symbols have different locality requirements.

Finally, we discuss a new architecture that leverages coding technique to improve the performance of Storage Area Networks. The key idea of our approach is to extend the capabilities of Software-Defined Networking (SDN)-enabled switches to allow them to perform both traditional forwarding operations as well as new encoding operation.

Bio: Dr. Sprintson is an Associate Professor with the Department of Electrical and Computer Engineering, Texas A&M University, College Station. From 2003 to 2005, he was a Postdoctoral Research Fellow with the California Institute of Technology, Pasadena. His research interests lie in the general area of communication networks with a focus on network coding and software defined networks. Dr. Sprintson received the Wolf Award for Distinguished Ph.D.students, the Viterbi Postdoctoral Fellowship, and the NSF CAREER award. Currently, he serves as an associate editor of the IEEE Transactions on Wireless Communications. He has been a member of the Technical Program Committee for the IEEE Infocom 2006–2015.
