Current works

• Leading the research project RODEO, which is engaged in international projects such has MICE (multimedia conferences), Password (security) or Hipparch (new architecture for high speed protocols). Apart from pushing everybody around, I was following closely the work on:
  • Network conscious applications, an example of which is IVS, developed by Thierry Turletti. The next step is on audio over the network, without resource reservation.
  • High speed marshalling routines, following the work of Philipp Hoschka.

  A short biography

  I have conducted for several years research in network protocols and network applications. I am now at Bellcore, in the Computer Networking Research department.

  From October 1986 to March 1996, I worked at INRIA in Sophia-Antipolis, where I led the research project RODEO. The objectives of the project are 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 parametrisation and of their insertion in the operating systems, and the study of the synchronisation functions and of the management of data transparency between heterogeneous systems. Amongst the output of the RODEO project, one can count one of the most performant ASN.1 compiler, MAVROS, and the IP based H.261 videoconferencing system, IVS.

  Previously, I took part to the NADIR project, investigating computer usage of telecommunication satellites, where I worked on the definition and development of specialized ``transport'' protocol for the high throughput, long delays and possibly multipoint links provided by the satellites -- this was the subject of my doctorate thesis. I joined then the GIPSI project, where I was in charge of developments of transmission protocols for the SM90 workstation, including a local network version of the X.25 protocol, a pre-NFS ``network disk'' protocol, an implementation of IP over X.25, OSI transport and session layer software and one of the earliest X.400 systems. After joining INRIA in Sophia-Antipolis, I 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.

  I was from 1991 to 1996 a member of the Internet Architecture Board (IAB), which I chaired between April 1993 and July 1995. I was elected a trustee of the Internet Society in May 1995.
