Biography of Christian Huitema

I am a "Distinguished Engineer" at Microsoft, working on innovative networking projects. Until December 2007, I was in charge of the "Wireless and Mobility Networking" team at Microsoft, in the "Windows Networking & Devices" group. I joined Microsoft in February 2000, working first as "architect" in the "Windows Networking & Communications" group. In my Architect role, I had the chance not only to provide general guidance on a number of TCP-IP related issues, but also to initiate several interesting projects, such as the integration of “presence” and “instant messaging” in SIP for real-time communication, the development of IPv6 transition technologies including Teredo for NAT traversal, and the Peer-to-Peer Name Resolution Protocol. In the wireless team, we developed the “native Wi-Fi” architecture, and are now preparing the support in Windows for a number of exciting technologies such as UWB, Wimax or Mesh Networking.

From 1996 to January 2000, I was chief scientist, and Telcordia Fellow, in the Internet Architecture Research laboratory of Telcordia, working on Internet Quality of Service and Internet Telephony. The work on Internet Telephony led to the development of the "Call Agent Architecture" that enables very large scale configuration, moving Internet telephony into the main stream of telecommunications. My personal work on quality of service focused on measurement of the Internet's size and quality.

From 1986 to 1996, I led the research project RODEO at INRIA in Sophia-Antipolis, France. I worked there on the definition and the experimentation of innovative communication protocols, software and compilers. One of our results was the IP based H.261 videoconferencing system, IVS, with which we demonstrated in 1994 that video communication can be made Internet friendly.

From 1980 to 1985, I was working at CNET (Centre National d'Etudes des Télécommunications), investigating computer usage of telecommunication satellites -- this was the subject of my doctorate thesis. I worked then on a join project between CNET and INRIA, where I developed communication protocols for the SM90 workstation.

Between 1975 and 1980, I worked as a software engineer at SEMA, first porting large Fortran programs to new architecture and then developing large Cobol applications for manufacture control.

I studied at the Ecole Polytechnique in Paris from 1972 to 1975, and obtained in 1985 a Doctorat ès Sciences from the Université Pierre et Marie Curie (Paris 6)

I was a member of the Internet Architecture Board (IAB) from 1991 to 1996, its chair between April 1993 and July 1995. I was elected a trustee of the Internet Society in May 1995, re-elected in May 1998, and served as a trustee until June 2001. I also served as a member of the board of the SIP Forum from 2001 to 2003.

I have written a fairly large number of scientific publications, articles and conference communications, as well as three books, "Routing in the Internet" (Prentice-Hall PTR, 1995), "IPv6, the new Internet Protocol" (Prentice-Hall PTR, 1996) and "Et Dieu créa l'Internet" (Eyrolles, 1995).
