摘要
随着VoIP的普及,对VoIP监测的需求愈加迫切,目前一般的网络测量工具不能满足VoIP监测的需要。首先介绍了VoIP的关键协议,讨论了VoIP监测的特点和目标,在此基础上详细讲述了一个在Linux平台下基于被动式抓包方法的VoIP监测系统的设计及实现,并重点讨论了一个可行的VoIP监听方案。
With the popularization of VoIP, the requirement of VoIP monitoring becomes more and more urgent. Most of the network measuring tools can not fulfil the requirement of VoIP monitoring. Firstly, this paper introduced the key VoIP protocols. Then it discussed the characteristics and the targets of VoIP momitoring. At the end, we detailed a design and implementation of a prototype VoIP monitoring system on the Linux, which based on passive packet capture method. In addition, it described a proper VoIP wiretap approval.
