| 摘 要： | 针对已有VoIP检测方法对协议解析依赖性较大,且检测范围不尽全面的问题,提出基于流统计特征的VoIP媒体网关检测方法.该方法通过对RTP流平均包到达间隔作同流计算与同源多流统计,得出对应网络实体的平均包到达间隔概率分布.根据同一IP地址所对应的平均包到达间隔分布的概率峰值判定媒体网关,从而大幅提高VoIP业务检测效率.

| Abstract: | To extend the range of monitoring VoIP traffic, this paper proposed a scheme for identification of media gateways, which was based on statistical flow characteristic. And the pivotal step was to get the probability distribute of mean inter-arrival time of packets, which needed operation in a single flow and statistic in flows from the same IP address. The media gateways can be confirmed by the peak value of the probability distribute of mean inter-arrival time of packets according to IP address, and the identification of media gateways will help to monitor VoIP traffic effectively. |
