Walter David "Dave" Sincoskie (December 21, 1954 – October 20, 2010) was an American computer engineer. Sincoskie installed the first ethernet local area network at Bellcore, and helped invent voice over IP technology. Sincoskie authored the first local ATM specification. He is also the inventor of the VLAN.
Sincoskie received his bachelor's degree, master's degree, and Ph.D in Electrical Engineering from the University of Delaware. His doctoral adviser was Dave Farber.
Sincoskie worked for Bell Laboratories in Murray Hill from 1980 to 1983. In 1984 he moved to the newly formed Bellcore (now Telcordia), where he was District Manager of the Computer Communications Research group for the first few years. During this time, Dr. Sincoskie worked on Internet telephony and as a result developed what is now known today as the VLAN.
From 1986 to 1990, he managed the Packet Communications Research Department, which spearheaded the telecommunications transition from circuit-switching to packet-switching, a key factor in the successful commercialization of the Internet. Dr. Sincoskie also co-authored the first specifications for Local ATM, which were later adopted by the ATM Forum.
From 1990 to 1996, Dr. Sincoskie was Executive Director of the Computer Networking Research Department at Telcordia. He managed a group working on the AURORA gigabit testbed, IPv6, IP over ATM, NSFNET, and broadband service control. He was the Project Director for two operational NSFNET Network Access Points, Chicago and San Francisco, which today interconnect approximately 150 Internet service providers.
From 1996 to 2008, he was senior vice president of Telcordia Technologies's Networking Systems Laboratory where, among other achievements, he pioneered the creation of Internet telephony. In 2008, Dr. Sincoskie left Telcordia and joined the faculty at the University of Delaware's Electrical and Computer Engineering Department as a full professor. At UD, he formed and served as Director to the Center for Information and Communication Sciences, jump starting the cyber security research effort at the institution.
