Bruno Kauffmann


I work as a permanent researcher at Orange Labs (formerly France Telecom R&D) since december 2010, in the "Traffic and Resource Management" (TRM) research group. My research interests include stochastic modeling and performance evaluation, with a specific application to the design, modeling and performance evaluation of caches.

I graduated from École Normale Supérieure (ENS) in 2007 and got a master degree in computer sciences from the MPRI, with a specialization in networking and distributed algorithmic.
From 2007 to 2010, I've been a PhD student in the ENS - INRIA Trec Project, under the supervision of Francois Baccelli. The goal was build connections between network theories (mostly queueing theory) on one side, and Internet probing and measurement on the other side.

More information is available on my personal web page.

Centres d'intérêt

I am working at the intersection of applied mathematics (mostly applied probabilities and statistics) and networking fields, with a strong focus on stochastic modelling and performance evaluation.

I am currently focused on two main research axes:

  • the modelling and evaluation of high speed networks,;

  • The evaluation, dimensionning and parameterization of cache policies in networks;

From my PhD., I keep an interest (and some skills) in tomography and active probing for networks.
