Part I

• Motivation of the measurements• Measurement methodology• Measured IPv6 deployment results• Conclusions

IPv6 deployment monitoring4

IPv6 measurements

• Provide information on the progress of IPv6 deployment in Europe

• First measurement campaign in October/November 2009• Second measurement campaign in October/November 2010• This presentation presents results of the second measurement

campaign and compares these with the first measurement results• Make a statement to which extend the target set by the European

Commission to have 25 percent of the European citizens capable of accessing the IPv6 internet is met.

Note: measurement platform measures continuously in time.

• Have webmasters place a script on their website that causes end users to connect to measurement server.

• Measurement server measures user’s IPv4 and IPv6 connectivity

Measurement Methodology

webbrowser

1. http request IPv4/IPv6

webpagewith TNO JAVA script

2. JAVA script

HTTP/PHP server MySQL serverand logging tool

users between countries • 2% increase in IPv6 deployment

Conclusions

• IPv6 deployment has not significantly improved over the last year.

• IPv6 accessible content has not become available in a significant amount

• The fraction of unique users capable of accessing the Internet over IPv6 has grown less than a percent.

• The target set by the European Commission to have 25 percent of the European citizens capable of accessing the IPv6 internet is not met.

• Results are in line with outcomes from the interviews and questionnaires and bottleneck studies.

Part II

• Reflecting on IPv6 measurements• Improving IPv6 deployment measurements• Discussion (separate agenda item)

IPv6 deployment monitoring16

Reflecting on IPv6 deployment measurements

• Large number of measurement initiatives and consortia exist• Active measurements• Passive measurements• Technical vs. non-technical

• Common implementation problems• Uniformity of data set• Representativeness of data set• Poor business case• Privacy

• Different measures for IPv6 deployment• User oriented• Network oriented• Service, content, data oriented

IPv6 deployment monitoring17

Measure once, analyze as often as you like

• Holistic approach improves efficiency and effectiveness of measurements by exchanging results between measurement groups and reuse of data and results

• Separation of data acquisition layer and shared interfaces for analysis module plug-ins.

Discussion

• Dealing with privacy

• Ownership, maintenance of, and contribution to data acquisition platform, (processed) data, (analyzed) results

• Feasibility
