This article, by William H. Graves, President of the COLLEGIS Research Institute, and former Senior Information Technology Officer and founder of the Institute for Academic Technology (IAT) at the University of North Carolina, (discussed in the September 13, 1996 Scout Report), contains a thought-provoking and succinct defense of the concept of "differentiated network services and related quality-of-service guarantees," that has evolved into Internet2 (discussed in the April 11, 1997 Scout Report) and the University Corporation for Advanced Internet Development (UCAID). Highlights include a short history of the development of Internet2 and UCAID, and a discussion of the spiral "life cycle" model of the Internet, as well as the place of Internet2 in that cycle.
