this paper is conducted to analyze the performance of unicast networks under different criteria by using different queuing protocols. This was done by creating a network simulation through NS-2. The data traffic used in the simulation was CBR traffic and it is a representation of multimedia data in NS-2. The protocols that were tested in the simulation were FIFO, FQ, RED, DRR and SFQ. These protocols, including its performance were evaluated and compared to each other in case of packets loss ratio, dropping fairness, end to end delay and delay jitter. Also, this research provides background and some related literature for the performance of unicast networks including queuing algorithms, performance metrics, congestion avoidance and quality of service. Overall results of this study showed that FQ, DRR and SFQ were providing better performance compared to other protocols. However, the best three protocols had different orders based on the performance metric conducted. The scope of this research is focusing only on unicast weird networks, so this work is not applicable for multicast or wireless networks. The proposed model is to show the way how the performance evaluation of unicast networks using different networks queuing protocols under different criteria has been conducted. Results in this study are trusted because they are collected by a very powerful tool called NS-2 or network simulator version 2. It is a very trusted tool in network area because the high reputation it has.
