www.ipv6net.ro IPv6 Network Evaluation Testbed

IPv6 is not backwards compatible

The Internet will have to withstand a period through which both protocols will coexist

Currently only 2.09 % of worldwide Internet users have IPv6 connectivity

3


The IETF introduced multiple transition scenarios

Many transition technologies have also been introduced (e. g. MAPe, NAT64, DSLite)

WHICH ONE is most feasible for a specific scenario ?

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


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

18


Formula for the calculation of GFI

Rough idea, use a weighted average

GFIASAMAPe= Wmetric1 * Smetric1 + Wmetric2 * Smetric2 …

Wmetric1 – weight of metric1

Smetric1 – score for ASAMAPe for metric1

Metric for scalability

Metric for Security quantification
