Apparatus and method for identifying an access network of a networked terminal

摘要

Disclosed herein is an apparatus and method of identifying an access network. The apparatus including: a packet capturing unit configured to capture a plurality of packets transmitted or received by a server; a flow classifying unit configured to classify each of the captured packets into individual flows with reference to at least one of an origination address, a destination address, and a port number; a round trip time (RTT) calculating unit configured to calculate RTT values from the packets classified into a flow of the individual flows; an access network determining unit configured to determine that an origination address included in a packet classified into the flow is an address accessing the server through a first communication network when the RTT calculated values exceed a reference value; and a storage unit configured to store the address accessing the server through the first communication network.
