Abstract:
1. A statistical information generator for VoIP (Voice over Internet Protocol) traffic analysis, comprising: a packet collection module collecting packets from a network; and a statistical information generation module analyzing information of a call setup packet or a media packet among the packets collected by the packet collection module, and generating statistical information of the network; wherein the statistical information generation module comprises: a structure generation module receiving the packets collected by the packet collection module, classifying the packets into the call setup packet and the media packet, generating a call setup information structure by analyzing information of the call setup packet if the received packet is the call setup packet, and generating a media information structure by analyzing information of the media packet if the received packet is the media packet; a call setup statistical information generation module receiving the call setup information structure from the structure generation module, and generating call setup statistical information by combining the call setup information structures using at least one of transmitter identification information, receiver identification information, and call identification information among information of the call setup information structure as a key value; a media statistical information generation module receiving the media information structure from the structure generation module, and generating media statistical information by combining the media information structures using media session identification information among information of the media information structure as a key value; and a statistical information transmission module receiving the generated call setup statistical information or the media statistical information from the call setup statistical information generation module or the media statistical information generation module, generating the statistical information of the network, and transmitting the statistical information to an analysis server.
