Contributions To The Internet
For fourteen years, Wolff worked as a communications and technology researcher for the United States Army. While working for the Army, Wolff introduced the UNIX operating system to Army labs in the early 1980s. Also while working for the Army, Wolff managed a research group that participated in the development of ARPANET, a major technology precursor to the Internet.
In 1986, Wolff became Division Director for Networking and Communications Research and Infrastructure at the National Science Foundation where he managed the NSFNET project which included a national backbone network in the U.S. that interconnected NSF sponsored supercomputing centers, regional research and education networks, federal agency networks, and international research and education networks. The five super computing centers were located at Princeton, Cornell, the University of California at San Diego, the University of Illinois at Urbana-Champaign, and the University of Pittsburgh. Wolff also managed grants to link the nation's universities together into regional networks that connected to the backbone and so provided universal connectivity to the academic community. The NSFNET was compatible with, interconnected to, and eventually replaced the ARPANET network.
Wolff also conceived the Gigabit Testbed, a joint NSF-DARPA project designed to prove the feasibility of IP networking at gigabit speeds.
In 1994, Wolff left NSF and joined Cisco where he helped with projects such as Internet2 and the Abilene Network. Wolff's career at Cisco began as business development manager for the Academic Research and Technology Initiative program. There Wolff helped advance the University Research Project (URP) which supports academic research candidates with grants to further networking technology. He was named the interim Vice President and Chief Technology Officer of Internet2 on March 31, 2011.
