A special random selective service queueing model for access to a star LAN

Abstract In this paper the multiple star LAN is first reduced to a new collision-elimination access mode. The new queueing model for this kind of access mode has been built. The model abides by a special random selective service, i.e., instead of selecting a customer randomly from all the waiting customers, the server will select one customer from a part of them. Apparently this is a new queueing model. The performance evaluation for the new multiple star LAN has been finished by calculating the steady-state characteristics of some important parameters, such as mean queueing length, mean waiting time, etc. Some of them have been simulated on the computer, and some important results have been obtained.
