Curriculum Vitae - Mr. John C. Klensin
Mr. John C. Klensin is Internet Architecture Vice President at AT&T and also has chaired the IETF's Internet Architecture Board since April 2000. Prior to joining AT&T, he was Distinguished Engineering Fellow at MCI and then MCI WorldCom, where he had lead responsibility for the design of many aspects of the internetMCI and marketplaceMCI offerings (the latter was probably the first major commercial effort in multi-vendor Internet business to consumer ecommerce). Prior to coming to MCI in mid-1994, he was INFOODS Project Coordinator for the United Nations University and, before that, was at MIT for nearly 30 years.
As a long-term contributor to the design of the administrative systems for the Internet such as those for top-level domains and MIME media types, Mr. Klensin was heavily involved in the process of converting those systems to more formal private sector control. He served on the IANA Transition Advisory Group and was active in the initial phases of organization and technical structuring of the new Internet Consortium for Assigned Names and Numbers (ICANN).
He has also been an active technical contributor to the Internet, beginning with the original ARPANET file transfer protocol (from which Internet email developed) and continuing more recent efforts including international character sets and multimedia data and performance improvements for HTTP. He has also served as a working group convener within ISO/IEC JTC1 and as a member and Vice Chair of ANSI's Information Systems Standards Board whose responsibilities included oversight for US participation in JTC1. Mr. Klensin was also founding co-principal investigator of the Network Start-up Resource Center project which provides technical assistance for creation of computer network connections to developing areas (including initial domain name management) and continues as a senior advisor to that activity.
