Christian Huitema is a Distinguished Engineer, and the General Manager for Wireless and Mobility Networking in the Windows Networking and Devices group. He joined Microsoft in February 2000 as an architect in the Windows Networking and Communications group. In his architect role, he provided general guidance on TCP-IP related issues, and initiated three projects: 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, his team developed the “native Wi-Fi” architecture, and added support in Windows for a number of exciting technologies such as UWB, Wimax or Mesh Networking.
From 1996 to January 2000, Huitema was chief scientist and Telcordia Fellow, in the Internet Architecture Research laboratory of Telcordia. There he worked on Internet Quality of Service and Internet Telephony. This led to the development of the "Call Agent Architecture" that enables very large scale configuration, and 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.
From 1986 to 1996, Huitema led the research project RODEO at INRIA in Sophia-Antipolis, France. His work focused 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 was demonstrated that video communication can be made Internet friendly.
From 1980 to 1985, Huitema worked at CNET (Centre National d'Etudes des Télécommunications), investigating computer usage of telecommunication satellites, which was also the subject of his doctoral thesis. He also worked on a joined project between CNET and INRIA, where he developed communication protocols for the SM90 workstation.
Between 1975 and 1980, Huitema worked as a software engineer at SEMA, first porting large Fortran programs to new architecture and then developing large Cobol applications for manufacture control. Huitema studied at the Ecole Polytechnique in Paris from 1972 to 1975, and obtained a Doctorat ès Sciences from the Université Pierre et Marie Curie (Paris) in 1985.
He was a member of the Internet Architecture Board (IAB) from 1991 to 1996,and its chair between April 1993 and July 1995. He was elected a trustee of the Internet Society in May 1995, re-elected in May 1998, and served as a trustee until June 2001. He also served as a member of the board of the SIP Forum from 2001 to 2003.
Huitema has written a 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).
