Abstract
In times of Internet access becoming a popular consumer application even for "normal" residential users, some telephone exchanges are congested by customers using modem or ISDN dial-up connections to their Internet Service Providers. In order to estimate the number of additional lines and switching capacity required in an exchange, the Internet access traffic must be characterised in terms of holding time and call interarrival time distributions. In this paper, we analyse six months worth of log files tracing the usage of the central modem pool and ISDN access lines at University of Stuttgart. Mathematical distributions are fitted to the measured data and the fit quality is evaluated with respect to the blocking probability observed in a multiple server loss system loaded by the described traffic.
