Technology for identifying VoIP traffic based on H.323 protocol
基于H.323协议的VoIP语音流量识别

The H.323 protocol and the session process based on H.323 were analyzed, the session signature in the communication process produced by VoIP based on H.323 was introduced, the tuples of the communicators were abstracted, and then the whole VoIP traffic was identified. The corresponding scheme for traffic store, search, update and the algorithm for VoIP traffic identification were designed. Experiment indicates that this method can accurately identify the H.323-based VoIP traffic.
