CITI Seminar of Thomas Begin (LIP, UCBL Lyon 1) on April 2 at 11am

Title: Contributions to the Performance Modeling of Computer Networks
Date and Place: 02 / 04 / 2019 11:00 in TD-C
Host: Jean-Marie Gorce and Florent de Dinechin
In this talk, I will present some of my contributions to the fields of performance evaluation and computer networks. I will first discuss a new modeling framework to evaluate the performance of DPDK-based virtual switches in the context of NFV (Network Function Virtualization) networks. Then, I’ll describe a scalable stochastic model to accurately forecast the performance of an IEEE 802.11-based network. Finally, I will introduce an original reduced-state description for multiserver queues that breaks the combinatorial complexity inherent to the classical state description and that can easily handle examples with hundreds of servers.


Thomas Begin received his Ph.D. degree in Computer Science from UPMC (U. Paris 6) 2008. He was a post-doctoral fellow at UC Santa Cruz in 2009. Since 2009, he is an Associate Professor at UCBL (U. Lyon 1) in the Computer Science department. During the 2015-2016 academic year, he was on research leave at DIVA lab – University of Ottawa. T. Begin research interests are in performance evaluation, future network architecture, and system modeling. His principal applications pertain to high-level modeling, wireless networks, resource allocation and queueing systems.
