Abstract

In this paper, a comparative analysis study is proposed to select the best Ethernet switching mode for a particular computer network requirement. The selected switching mode is reliant on variable factors and parameters in the computer networks. The three Ethernet switching modes which are used in this study are store and forward, Cut-through, and free fragment modes. One of three used switching modes in this study is selected using analytic hierarchy process (AHP) technique as per requirement of a user. AHP is multi criteria decision making instrument created by Thomas Saaty in the 1970s. The criteria or parameters which are used to select best Ethernet switching mode are: latency, function, performance, port density, and cost. The experimental results prove that fragment free switching mode is the best among three switching modes with (0.422) score.
