Community News

After four years serving CCR, the ACM SIGCOMM newsletter, the editor in chief is now Srinivasan Keshav from University of Waterloo, Canada. The reputation of CCR is now increasing quickly. Do not forget CCR Online, where you can post articles, comments, and interact online with the CCR community.

CoNext has now been successful for three years. It is sponsored by ACM SIGCOMM and the goal is to make it the winter top-notch event. In 2008, CoNext is held in Madrid, Spain.


Research Interests

The Paris Lab federating research theme is "Advanced peer-to-peer services". Research activities and area of interests are described in details in the Thomson Paris Research lab overview. Our research focuses on how to provide new communication services on the Internet, and what communication architecture needs to be deployed side by side with the Internet to support these new communication services when the Internet does a bad job.


Projects & Cooperation

Thomson Paris Research Lab is involved in the following projects:

Haggle is a European FET project under the SAC area, with the following partners: THOMSON (FR), University of Cambridge (UK), University of Uppsala (SW), EURECOM (FR), EPFL (CH), SUPSI (CH), CNR (I), and Martel (CH). Haggle is a communication architecture that enables opportunistic communication between networked devices. We named the Haggle communication paradigm "Pocket Switched Network" as data take advantage of both network availability and device mobility to achieve communication services. The Haggle implementation called MobiClique is going to be soon available on windows mobile and symbian phones. Stay tuned!

WIP is a cool project that deals with wireless mesh, community networking, and advanced access point architectures (multiple radio, directional antennas). WIP terminates in December 2008.

NaDA, or Nano Data Center is a new 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 90% capital investment to ISPs, and also 90 to 95% energy in the data delivery process. NaDa, thanks to its "managed Peer-to-peer" communivation 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. Partners are Telefonica, Eurecom, SIT (Fraunhofer), UPMC, CERTH, and Martell.

ONELAB2 is The experimental platform federation project in Europe. It is extending PlanetLab with new testbeds, new technologies, new communication pardigms. ONELAB2 is funded by the EU FIRE unit and is led by UPMC.

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 starts from the 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 that has implemented OSI TP4, moreover in OCCAM :-( 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 Sprintlink. Research reports and exciting data are reported on the IPMON web site.

Between April 2003 and Septembre 2005, I worked with INTEL Research in Cambridge. At IRC, I have launched three projects in the area of network monitoring, wireless networking and opportunistic communication. IRC 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 addition to management and lab organization, my research activities will focus on taking a top-down approach to communication services, where measurement and experimental work will be two important methodological components. In 2006, I became an ACM fellow for contributions to the measurement and analysis of computer networks. Since July 2008, I am also CTO of Thomson Corporate Research.
