A study was made of management practices in different computer networks. The five networks were chosen as typical of different approaches to network implementation and management: Defense Advanced Research Projects Agency (ARPA) Network, MERIT Network, Triangle Universities Computation Center (TUCC), Oregon State Regional Network, and Tymnet (a commercial network). A common format which included questions about network mission, technology and organization; financial and legal concerns; and summary of problems and tentative recommendations was used to survey each organization. The resulting report is not intended to be prescriptive, although some empirical observations are presented for each topic covered. (Author/SL)
