Abstract: A variety of IPv4 to IPv6 transition techniques have been identified and implemented. In this thesis, we conduct TCP performance testing of three kinds of typical transition mechanisms. According to Our experiment results, each technique does induce performance decline, but their effect degrees are not uniform. Tunneling techniques generally present better performance than translation techniques. We analyzed some factors that probably result in performance difference among these translation techniques. In this thesis, we also improve NAT-PT performance by transforming the centralized system into a distributed system. We conduct a set of experiments to compare TCP performance of distributed NAT-PT and centralized NAT-PT. Our experimental results show that, although distributed NAT-PT consumes some resource to implement mapping table synchronization, the effect is limited which results in 1% a?? 12% performance reduction. With load balance of network traffic, the overall performance of distributed NAT-PT presents obvious improvement over the original centralized NAT-PT system.
