摘要:
针对域名系统(DNS)服务质量评价问题,通过对网络行为数据流的分析,结合路由路径平均长度等5个影响网络性能的主要参数,评价用户与DNS递归解析服务器之间的网络服务质量。对各参数对服务质量的贡献度进行量化分析。结合量化分析结果,建立基于贡献度的DNS服务质量评价模型。以Alex top1000域名作为基准数据集,对国内外55个DNS服务器进行测试与评价。测试结果及服务质量综合评价结果表明DNS服务器间的服务水平差别较大,离探测点近的DNS服务器服务质量相对较好,建议优先选取。
Abstract:
Aiming at the quality of service(QoS)estimate problem of domain name systems(DNS),the QoS of networks between users and DNS recursive resolution servers are estimated by analyzing the network data streams and combining with the average lengths of routing paths and other four parameters influencing the network performance.The contribution degree of every parameter for QoS is quantitatively analyzed.Combining with the result of the quantitative analysis,a QoS estimate model of DNS based on contribution degrees is established.The QoS of 55 DNS servers from home and abroad are tested and estimated with the Alex top 1 000 domains as the benchmark data.The test and estimate results of QoS show that the QoS level differences of DNS servers are great,and the DNS server close to the probe point has relatively superior QoS,which should be selected first.
