| Abstract | IPv4 addresses have already been exhausted and internet community is arranging a move from IPv4 to IPv6. But migration is not going to happen overnight. IPv4 and IPv6 must co exist. Since, very few IPv6 applications prevail in market, ISPs are reluctant in upgrading their core. They wish to provide IPv6 connectivity through their existing MPLS enabled IPv4 core, with minimum expense and less configuration difficulties. The goal of this study is to assess the performance of mixed IPv4 and IPv6 traffic when passed through DiffServ aware MPLS IPv4 core. Simulation is carried out for two transition mechanisms, PE and 6VPE We use GNS3 to configure and run topology, and Iperf3 to generate and capture data streams for the study. The key contribution of this study is that it aims to evaluate performance of hybrid IPv4 and IPv6 traffic over traffic engineered network, which in earlier studies were evaluated separately. Result shows no critical distinction in the performance of IPv4 and IPv6 traffic under normal condition. EF class traffic shows better performance than AF41 class traffic. LER performs load balancing and forwards IPv4 and IPv6 AF41 traffic along separate paths. When EF traffic is introduced, it takes path along IPv6 AF41 traffic. Because of this, throughput for IPv6 AF41 decreases, and jitter increases significantly, and there is significant packet loss too. Overall, there is no critical difference in the performance of 6PE and 6VPE transition mechanism. |
