摘要 |
<p><P>PROBLEM TO BE SOLVED: To easily and accurately specify a communication device which performs P2P communication. <P>SOLUTION: A P2P communication device 300 which is installed with software for P2P communication is connected to a communication network 7. A communication information collection device 200 is also connected to the communication network 7 for acquiring packets transmitted on the communication network 7 to acquire communication histories including the IP address and the port number of a transmission source or a transmission destination from the acquired packets. In addition, a communication analyzer 100 is connected to the communication network 7 for extracting a communication history including an IP address assigned to the P2P communication device 300 as a transmission source or a transmission destination from the communication histories to acquire the IP address and the port number of a communication device that is a communication partner of the P2P communication device 300 from the extracted communication history to specify the communication device 400 which is under P2P communication. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
