This paper presents development of the wired LAN overall performance model. We investigated the performance characteristics of major LAN components, that is, media, protocols, traffic and devices; determined the main characteristics amongst them and their interrelation; and applied mathematical principles to develop a model which captures the overall network performance in terms of its characteristics. The model works for wired LAN specifically therefore it cannot be used for other networks unless it is developed further to accommodate necessary and relevant performance elements. 

 

Key words: Network performance, wired LAN, performance elements.
