Performance investigation of IPv4/IPv6 transition mechanisms

1Pv4/1Pv6 transition always occurs process in deploying 1Pv6-based services across the 1Pv4 Internet. The IETF Next Generation Transition Working Group (NGtrans) has proposed many transition mechanisms to enable the seamless integration of 1Pv6 facilities into current networks. This work mainly addresses the performance of the various tunneling transition mechanisms used in different networks. The effect of these mechanisms on the performance of end-to-end applications is explored using metrics such as transmission latency, throughput, CPU utilization and packet loss. The measured latency and throughput of the 6to4 mechanism are better than those of the configured tunnel and tunnel broker mechanisms by 89.38% and 94.83%, 42.47% and 48.76%. However, the 6to4 mechanism must work much harder (greater overhead) for each packet sent, and it must therefore run at a higher CPU utilization of the edge router. Larger packets had higher loss rates, for all three tunneling mechanisms.
