一种基于查询事件的域名服务器日志模型
A DNS Logging Model Based on Query Event
-
摘要: 提出了一种基于查询事件的日志模型, 采用查询/应答日志匹配的方法完整的记录了一次查询事件, 利用内存数据结构提高了海量数据写入的I/O效率;在日志分析过程中对日志文件建立二维哈希索引, 利用布隆过滤器减少磁盘I/O次数, 提高了分析效率.Abstract: In this paper, we investigate a logging model based on a complete DNS query event.The corresponding query/response matching technique is designed, equipped with a facility of memory caching to solve the performance bottleneck of the insertion operations.Furthermore, a mechanism of two-dimensional hash indexing with Bloom Filter is designed to improve searching and retrieving by reducing disk I/O.
