IEICE Trans on Communications, Vol.E74,No.9,pp.2756-2764(1991)

This paper is a discussion of the utilization of a campus network at Shinshu University called S-net. S-net was constructed and put into use in 1985, and a total of 48,734 persons made use of S-net in 1990. The structure of S-net is explained and then a description of its current layout is presented. The transmission capabilities of S-net are investigated and the state of utilization of the network is described. The number of S-net users by hour forms a distribution which peaks at 4:00~p.m. and again at 10:00 p.m. Furthermore, a questionnaire survey among S-net users was conducted and the requests and requirements expressed pertaining to the campus network are presented. From these results it can be seen that the demands on the campus network are great. And it was revealed that although a strong desire was voiced on one hand for improvements in the present user environment, requests concerning multi-media networks or connections to off-campus networks exist as well. Finally, the points of improvement of future S-nets based on the opinions and suggestions of the users and six years of actual operating experience with S-net are discussed.
