The new of internet applications and the traffic coming with it are rapidly growth, the developer of the internet infrastructure needs a high level of quality of services. The high quality of service (QoS) makes main problem with uncontrollable amount of traffic (Congestions) on the internet.
Usually, the internet routers are content two types of queue management mechanisms reactive and proactive mechanism, this paper focus on two important proactive mechanisms these are Random Early Detection (RED) and Random Early Marking (REM), and how to improve the performance of the internet routers by chose the suitable proactive queue management algorithm, these selections are helping the TCP protocol to given guarantee to delivered the packets to the destination.
This paper going to design performance evaluation modelfor examining the RED,REM technique to mitigate the effectiveness of the congestion in the internet routers,and to identify the key parameters to decrease the packet drop in the way to destination by exam many factors such as throughput, packet loss, link utilization, and windowsize by using Network Simulation 2 (NS2). The result shows a good performance for the REM algorithm when compared with RED algorithm in the same scenario.
