3. Outline Introduction Measurement Target and Procedures Results on End-to-End Application Performance Conclusion

4. Introduction Research Background 1.The transition between IPv4 and IPv6. 2.Several transition mechanisms have been developed. 3.Evaluate before deploy.

5. Introduction Performance Degradation Prediction

6. Introduction Performance Degradation Prediction

7. Measurement Target and Procedures Measurement Target We have classified these mechanism considering the following factors: 1.Architectural Goal 2.Scope 3.Scenarios

8. Measurement Target and Procedures (a) An IPv6 node connecting to an IPv6 node through an IPv4 network. (b) An IPv6 node connecting to an IPv6 node through an IPv4 network supporting NAT. (c) An IPv4 node connecting to an IPv4 node through an IPv6 network. (d) An IPv6 node connecting to an IPv4 node. (e) An IPv4 node connecting to an IPv6 node.

25. Results on End-to-End Application Performance connect/request/response transaction rate

26. Conclusion Our goal was not to evaluate a specific router or host, but to empirically analyze impacts on transition mechanisms compared with IPv4- only and IPv6-only network performance. Future work: We intend to investigate mechanisms with security (e.g, IPsec).
