Abstract:
1. A communication management system, comprising: a first peer-to-peer node; a second peer to peer node which has a peer to peer connection to communicate with a the first peer to peer node; a user terminal having a peer-to-peer data connection with the second peer-to-peer node; a node detector which refers to communication data transmitted from or to the first peer to peer node so as to detect identification information of the second peer to peer node and store the detected identification information in a node database, and said node detector detects the port number of a port through which the second peer to peer node conducts peer to peer communication, wherein the identification information includes the IP address of the second peer-to-peer node; and a communication control apparatus connected between the user terminal and the first and second peer-to-peer nodes, said communication control apparatus comprising: the node database which stores identification information of the second peer to peer node detected by the node detector, a search circuit which acquires communication data and searches the node database for identification information of the transmission source or transmission destination of the communication data, and a filtering circuit which performs filtering on the communication data in accordance with the search result of the search circuit; said communication control apparatus configured such that it:
