Christian Huitema

Christian HUITEMA has conducted for several years research in network protocols and network applications. He is now at INRIA in Sophia-Antipolis, where he leads the research project ``RODEO'', whose objective is the definition and the experimentation of communication protocols for very high speed networks, at one Gbit/s or more. This includes the study of high speed transmission control protocols, of their parametrization and of their insertion in the operating systems, and the study of the synchronization functions and of the management of data transparency between heterogeneous systems. The work is conducted in cooperation with industrial partners, and take into account the evolution of the communication standards.

Previously, he took part to the NADIR project, investigating computer usage of telecommunication satellites, where he took part to the definition and development of specialized ``transport'' protocol for the high throughput, long delays and possibly multipoint links provided by the satellites. He then joined the GIPSI project, where he was in charge of the developments of transmission protocols for the SM90 work station, including a local network version of the X.25 protocol, a pre-NFS ``network disk'' protocol, OSI transport and session layer software and one of the earliest X.400 systems. After joining INRIA in Sophia-Antipolis, he took part to to the ESPRIT project THORN, which has provided one of the first X.500 conformant directory system; the initial developments of the ASN.1 compiler MAVROS was done within this project.

Christian Huitema is a member of the Internet Architecture Board (IAB), and vice-chairman of IFIP working group 6.5 (Upper Layers Protocols, Applications and Architectures).

Walid Dabbous graduated from the Faculty of Engineering of the Lebanese University in Beirut in 1986 (Electrical Engineering Department). He obtained his DEA and Doctorat in Computer Science from the University of Paris XI in 1987 and 1991 respectively. He joined the RODEO Team within INRIA in 1987. Since 1991, he is Chargé de Recherche at INRIA. His main research topics are high performance transport and application protocols, congestion control, internet protocols, video conferencing and communication support for CSCW.
