| Abstract | The future IP networks are expected to use IPv6 rather than IPv4. This is mainly due to the limitation of IPv4 in terms of the number of addresses, routing and security. IPv6 has been designed, among other things, to satisfy the future network quality of service (QoS) requirements while IPv6 network offers significant advantages over the current IPv4 network, it will take some time to change from IPv4 to IPv6. Therefore, IPv4 and IPv6 will coexist during the transition period. A number of transition mechanisms are proposed by the Internet Engineering Task Force (IETF). We adopt the Dual Stack Transition Mechanism (DSTM) to study network performance with several types of traffic sources. We evaluate the network performance in terms of the bandwidth, throughput, the percentage of dropped packets, and mean end-to-end delay of each traffic flow in the network with both IPv4 and IPv6. We consider four types of traffic sources: VoIP IPv4, Internet IPv4, FTP IPv6 and MPEG-4 IPv6 with both video and audio. All the simulations are performed using the network simulator 2 (ns-2). The simulation results show that IPv6 with priority has better performance than IPv4. In particular, as we increase the traffic densities of IPv6 sessions, the bandwidths for IPv6 sessions increase at the expense of the decrease in the bandwidths for IPv4 sessions. On the other hand, increasing the bandwidths of IPv4 sessions do not increase their bandwidths due to their lower priorities. In addition, we observe that the increase in packet sizes for IPv6 traffic results in the increase in the mean end-to-end delay, but this is not the case for IPv4 traffic. |
