Stochastic Modeling of Lotus Notes with a Queueing Model

With the increasing popularity and diversity of computer systems, quality of services for computer applications becomes more and more important. In order to facilitate the theoretical studies on the computer performance management problem, an effective simulation environment is desired. In this paper, we propose a methodology of extracting a queueing model from the measurements of computer systems. In particular, a queueing simulator in the form of a closed queueing network is constructed from Lotus Notes log files with demonstrated accuracy.
