Abstract
Through analyzing on the resolution flow of domain name system(DNS), from the viewpoint of the end user, average length of routing path, round-trip time(RTT), delay jitter, bottleneck bandwidth, and packet loss rate are extracted as the performance measurement parameters of DNS resolution network, and the corresponding measurement methods are established. 60 DNS recursive servers of some provinces are measured. The measurement results show that, the average length of routing path of DNS is 13.29 hops, the average RTT is 104.33 ms, the average delay jitter is 2.403 ms, the average bottleneck bandwidth is 80.248 Mb/s(ICMP model) and 87.437 Mb/s(UDP model), and the packet loss rate is 6.077%.
