Comparative analysis of performance of hub with switch local area network (LAN) using riverbed in University of Technology (Utech), Jamaica

Abstract

Hubs and switches have been actively used devices in computer networks vision, over two (2) decades. As results, numerous approaches have been used with varying degrees of success to evaluate the performances of these devices in computer networks. A class of approach that has shown substantial promise is one that gives clear and predictive results regarding the numbers of workstations, servers and categories of cables used in the network is by riverbed academic edition, version 17.5 approach. A common theme in this green technique, to this approach is by creating two scenarios. In the first scenario, about seven (7) to ten (10) workstations were connected to web server via a hub. The relevant performance statistics were collected at both workstations and the server. The same was done in the second scenario except that the hub was replaced with a switch, which will facilitate the connections between the workstations and the server. Simulations in the laboratory-using riverbed version 17.5, were done to obtain the statistical comparative results of these two scenarios. This approach has shown to outperform other existing methods in comparative analysis of performance of hub with switch in a local area network (LAN).
