A Study of the IPv6 Service Availability Measurement

摘要

While confronting the global IPv4 address exhaustion, it is important and crucial for the entire Internet environment to smoothly upgrade to the next generation Internet Protocol, IPv6. Based on the statistics of the user availability of Google, the global usage of the IPv6 is still very low. As we knew, the service availability is one of the key factors affecting user availability, how to handle the IPv6 service availability measurement becomes a critical topic for the IPv6 upgrade. In previous researches, two points of views for estimating the IPv6 service availability have been proposed. One is to calculate the ratio of all ccTLD IPv6-enabled services to all ccTLD services, and the other is to calculate the ratio of all IPv6-enabled services in the top k popular services to k. In the former method, the importance of each service is treated as equal and the related data need to be provided by its ccTLD. In the latter method, the top k popular services representing the all services are used to calculate the IPv6 service availability and the related data could be obtained by certain public web sites. In this study, we proposed a hybrid method to analyze the service availability using the global top one million popular web sites and top 500 ccTLD's popular web sites from Alexa. In this study, four criteria have been defined and experiments have been made to verify our hypothesis.
