Abstract :
DNS is an important application as a part of the procedures of most Internet applications, which means quality of DNS directly influences quality of these applications. In order to monitor and analyze user perceived end-to-end quality of DNS applications, two key parameters of DNS quality were chosen. A distributed system NQM was used to monitor various types of practical DNS services by deploying monitors in different provinces and accessed to main ISPs in China by Ethernet, ADSL and 3G wireless terminals. Monitors were properly configured to avoid responses from OS or ISP DNS server cache caused by last query. Based on monitoring data, different aspects of user perceived DNS quality are analyzed in comparison with wired and wireless clients, idle and busy times, weekdays and weekend. Some realistic interesting conclusions are summarized.
