<P>PROBLEM TO BE SOLVED: To provide a user terminal connection network identification device and method and a computer readable storage medium. <P>SOLUTION: A user terminal connection network identification device comprises: a packet capture unit which captures a plurality of packets transmitted or received between a user terminal and a server; a flow classification unit which classifies the captured packets into individual flows by referring to at least one of the source address, the destination address and the port number of each of the plurality of packets captured by the packet capture unit; an RTT calculation unit which determines a round trip time (RTT) value from the packets classified into the same flow by the flow classification unit; and a connection network determination unit which, when the RTT value calculated by the RTT calculation unit exceeds a set reference value, determines that the source address included in the packets transmitted to the server in the same flow is the address to be connected to a first communication network. <P>COPYRIGHT: (C)2013,JPO&INPIT |
