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
web server
end user 3. PHP call
TNO IP monitoring server:- ipv4.test.ipv6monitoring.eu- ipv6.test.ipv6monitoring.eu- ipv4v6.test.ipv6monitoring.eu
PHP call via-IPv4 only-IPv6 only-dual stack

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
