| Summary: | Approved for public release, distribution is unlimited === The analysis of LAN performance is the main objective of this research. LANs can be configured in various ways combining different medium access control mechanisms and different physical layer specifications. Details on these alternatives are specified in IEEE 802.3 through IEEE 802.5. We study th performance of different types of LANs under various configurations of servers and stations. The queueing network model is one of the analytical tools to help investigate the performance characteristics of various LAN configurations. Since the analytical approach based on queueing network models is often too complicated to be practically used, we rely on simulations. Thus our analysis will be based on simulations, and SIMLAN II will be the simulation tool for our work. Our specification of simulation models involves three classes of transactions, and one or two servers. There are 24 simulation results in this thesis. These results, which are arranged in tables and figures, help compare th performance characteristics of various LAN configurations.
