Tom Henderson is principal researcher for ExtremeLabs, Inc., of Indianapolis. ExtremeLabs performs systems analysis and performance testing in medium- to high-end networking and microprocessor-based systems platforms. While much of the research is published in major trade publications, ExtremeLabs also performs private testing and simulation on network traffic performance-- especially in the field of isochronous applications (multimedia). ExtremeLabs also performs technical investigations for venture capital organizations.
Prior to ExtremeLabs, Tom was the senior vice president of Unitel, and its successor company, publically traded Telecomm Industries Corporation (TCMM). TCMM was one of the largest interconnects in North America, and Tom's responsibilities were architectural/framework design, engineering overview and oversight, as well as serving as principal engineering liaison to business partners.
Unitel acquired Tom's company, Corporate Networks, Inc., in 1993. Corporate Networks was a communications/network integration concern with twenty-one employees. For the eight years prior to the acquisition, Tom and his crew designed and deployed over 500 local networks in the central region, and was a vendor/consultant to universities, Fortune 500 firms, non-profit organizations, and others-- specializing in local networks and network-to-mainframe connectivity.
Tom was a co-founder of the Local Area Network Dealers Association in 1985, whose US organization later merged with the Business Technology Association; the Canadian organization survives independently. Tom was also the founder of the Computer Telephony Resellers Association, which merged with the MultiMedia Telecommunications Association. Tom served for several years as a member of the MMTA board of governors, and voted for the merger between the MMTA and the TIA.
Tom currently serves on the technical program committee of the International Communications Association (ICA), the Conference Advisory Board for COMDEX Spring, Fall, Canada West, and Toronto. Tom is also a director of PBS affiliate WFYI-20 in Indianapolis. The father of two, Tom's non-computer passions are music, travel, and restoring old Jags. He's working on his PhD in computer science research.
