News

TECHNICOLOR has recently opened a new Research Lab in Palo Alto. This lab focuses on machine learning, privacy, and user knowledge. It is led by Jean Bolot. I am based in Palo-Alto in 2011 to help build and integrate the lab.

Research Interests

My research activities focus on content distribution, and more recently user knowledge and recommendation. 

Projects & Cooperation

NaDA, or Nano Data Center is a content delivery paradigm where content is stored on the home gateways, in such a way that it can be accessed quickly and securely by customers. We expect NaDa to save up to 70% capital investment to ISPs, and similar savings in energy. NaDa, thanks to its "managed Peer-to-peer" communication infrastructure, will allow a large range of new services to be deployed quickly and safely such as P2P games, User generated Services, VoD, Catch-up TV, etc. NaDa is funded by the EU FIRE program. You can see the NaDa clip on youtube.

C’MON, or collaborative monitoring, is an ambitious measurement project funded by ANR, the French national research agency. C’MON is trying to infer the performance of ISPs relying only on information collected by Internet users. C’MON builds on grenouille.com monitoring package and will enhance it with new measurement and inference techniques. Even stronger: the project will also try to detect when ISPs try to hide perfromance or availability problems to their customers.

Bio

I got my PhD in Computer Science on January 30, 1991, in Grenoble (FRANCE). During this period, I worked on high performance implementations of Transport protocols. I am certainly one of the few who has implemented OSI TP4 in OCCAM on a multi-Transputer platform that I designed, without a debugging tool :-( I also took part to the design of XTP, and of its hardware implementation, the Protocol Engine. I joined the RODEO project at INRIA Sophia-Antipolis in October 1993 . The activity of the RODEO project was focused on Internet multimedia applications and protocols.

From October 1998 to April 2003, I worked with Sprint Advanced Technology Labs. I was given the opportunity to build a new research group which problematic was to understand how to make backbone management easier and performance higher. We designed a unique measurement infrastructure made of GPS synchronized packet traces, routing events, SNMP data, and active probing. The knowledge extracted from these data allowed us to design tools, models, and traffic engineering mechanisms, most of them being used by Sprint. 

Between April 2003 and Septembre 2005, I worked with INTEL Research in Cambridge. I have launched three projects in the area of network monitoring, wireless networking and opportunistic communication. INTEL Research gave me a unique opportunity to broaden my research scope and get some knowledge in new research areas.

I have joined Thomson in October 2005 to create and manage the Paris Research Lab. In 2009, Thomson became TECHNICOLOR and I became Chief Scientist. I am now in charge of the long term research strategy for the company, as well as academic relationships, fellowship program and Scientific Advisory Board.

I am an ACM fellow since 2006 for contributions to the measurement and analysis of computer networks.
