【摘要】 CN顶级域名的DNS日志从分布式站点传输到数据处理中心时,对海量数据存储和传输带宽提出极大挑战。针对该问题,提出一种高效的DNS日志压缩算法,利用DNS查询类型的冗余性和DNS查询时间、IP地址和域名等的重复性进行DNS日志压缩。实验结果证明了DNS日志压缩算法在DNS实时监控和分析系统中部署的有效性和高效性。更多还原

【Abstract】 In the deployment of real time Domain Name System(DNS) monitoring and analysis system,the large volume CN top level domain DNS log heavily burdens its transmission from the distributed sites to the data processing center.The redundancy of DNS query type and the repetitiveness of DNS query time,IP and domain name are utilized for the DNS log compression to facilitate its transmission.For IP and domain name compression,the algorithm relies on their concentration property as well as their time and space locality.更多还原
