Christian Huitema joined Microsoft in February 2000, as "architect" in the "Windows Networking & Communications" group. The group is in charge of all the networking support for Windows, including the evolution of TCP/IP support, IPv6, Real-Time Communication, and Universal Plug and Play (UPnP).
Prior to joining Microsoft, he 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. His personal work on quality of service focused on measurement of the Internet's size and quality.
Huitema joined Bellcore (now Telcordia) the 18 March 1996. From 1986 to 1996, he led the research project RODEO at INRIA in Sophia-Antipolis, France. He worked there on the definition and the experimentation of innovative communication protocols, software and compilers. One of the 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, he worked at CNET (Centre National d'Etudes des Télécommunications), investigating computer usage of telecommunication satellites -- this was the subject of his doctorate thesis. He worked then on a joined project between CNET and INRIA, where he developed communication protocols for the SM90 workstation.
Between 1975 and 1980, he worked as a software engineer at SEMA, first porting large Fortran programs to new architecture and then developing large Cobol applications for manufacture control.
He 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).
Huitema was a member of the Internet Architecture Board (IAB) from 1991 to 1996, its chair between April 1993 and July 1995. He was elected a trustee of the Internet Society in May 1995.
Huitema has 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).
