In Internet traffic is processed as quickly as possible, but there is no guarantee of timelines or genuine delivery. Different internet services such as FTP, VoIP and Video uses various traffic management systems. Queuing is one of the very essential mechanisms in traffic management system. Therefore Queuing disciplines are implemented in routers to administer, run, arrange and to prioritize packets in the buffers prior to their transmission. This paper attempts to analyze three queuing systems which show how the choice of the queuing discipline in the routers can affect the performance of the applications and the utilization of the network resources. The study has been carried out using OPNET Modeler simulation tool based on performance metrics as Traffic dropped Traffic Received and packet end to end delay and the simulation results illustrates that WFQ technique is superior compare to other techniques.
