基于DNS协议分析的流量监测系统
首发时间:2009-12-16
摘要:本文结合现有网络协议分析与流量监测技术,在广域网环境下,设计出一个新的基于DNS协议分析的网络流量监测系统,通过使用流量监控设备可以将TCP/IP网络中传送的数据包完全截获下来,并根据需求启用数据包捕获过滤机制,进行过滤和协议分析,进而解析还原得到我们所需要的DNS相关信息,然后利用关键字过滤技术,结合DNS服务提供商需求,达到对如DNS部署效率、用户行为分析等特定信息的快速获取和跟踪的目的,从而不仅可以方便DNS服务提供商有针对性地部署DNS服务器,同时也为其用户业务策略提供了一个很好的手段。

A Traffic Monitoring System Based on DNS Analysis
Abstract:In this paper, a new network traffic monitoring system which is based on DNS protocol analysis is designed, combined with network protocol analysis and network flow monitoring technology. Data packages of TCP/IP network can be captured by network traffic monitoring equipment, and it can be analyzed through data package filtering mechanism according to requirement, then the information we care about which is related to DNS will be resolved and be retrieved from the complicated protocols. The key word filtering technology will also be used and combined with the requirement of DNS service provider, the goal of DNS servers\
