Comparison between IPv4 and IPv6 QOS Based On Opnet Modeler

This paper present study of different (QOS) based on simulative and analytical methods in IPv4/IPv6 networks. This research aims to find out what internet protocol is better under the specific application .in doing so four different network loads in both scenarios are considered. In the context of network load, the importance of varying network load is realized while configuring and simulating the network models. For instance, a medium network load, high network load then a worst possible network load are considered to understand the impact on the delay in IPv4/IPv6 networks. Two Network models are defined which allow us to compare the Obtained results. In addition, IPv4 network model is used and extended in terms of configuring IPv6 network model as. The simulation has been carried out using Optimized Network Engineering Tool (OPNET).
