- 16. 16 www.ipv6net.ro IPv6 Network Evaluation Testbed Lack of control data Cross check the results with commercial benchmarking tools The diversity and complexity of existing production networks The methodology can be reproduced and customized results can be obtained Coping with the number of existing and future technologies Research collaboration can transform IPv6NET into an exhaustive IPv6 transition resource
- 17. 17 www.ipv6net.ro IPv6 Network Evaluation Testbed Using the proposed IPv6NET and the associated methodology we have identified the following feasibility trends: Closed Environment MAPe had a better overall performance followed closely by DSLite, MAPt and 464XLAT Translation-based technologies (464XLAT, MAPt) had better latency Encapsulation-based technologies (MAPe, DSLite) had better throughput Open Environment Applications capability results indicate asamap as a mature and suitable transition implementation Operational capability results indicate enhancements are needed before using asamap in a production network
