It is very important for designing thosesystems to avoid a performance decline by network access concentrationsto the networks and servers caused by users' operations. We evaluatedthe performance of various network topologies based on Ethernet to findproper designs for the networks for educational computer systems bysimulations in the access concentration scenarios.  To simulate usersbehavior in educational systems, we utilized models based on measuredbehavior in actual educational systems.
