【摘要】：通過對DNS解析數(shù)據(jù)流的分析,從終端用戶角度出發(fā),選取路由路徑平均長度、路由往返時延RTT、時延抖動、路徑瓶頸帶寬和丟包率作為DNS解析網(wǎng)絡(luò)性能測量參數(shù),并建立相應(yīng)的測試方法。對全國各省市首選及備份的60個DNS遞歸解析服務(wù)器進行主動測量。測量結(jié)果表明:DNS解析路由路徑平均長度為13.29跳,平均往返時延為104.33 ms,平均時延抖動為2.403 ms,瓶頸帶寬分別為80.248 Mb/s(ICMP方式)和87.437 Mb/s(UDP方式),丟包率為6.077%。
[Abstract]:Based on the analysis of DNS data stream, the average length of route path, the delay jitter of RTT, the bottleneck bandwidth and packet loss rate of DNS are selected as the parameters of network performance measurement from the point of view of end user. And establish the corresponding test method. The 60 DNS recursive parsing servers selected and backed up by provinces and cities in China were measured actively. The measurement results show that the average length of DNS parsing routing path is 13.29 hops, the average round-trip delay is 104.33 ms, the average delay jitter is 2.403 ms, the bottleneck bandwidth is 80.248 Mb/s (ICMP mode) and 87.437 Mb/s (UDP mode), and the packet loss rate is 6.077.
