Abstract
A network device connects a terminal device to the Internet using a plurality of connections. The network device obtains a quantity of different destination port numbers employed by the plurality of connections, calculates a ratio of the quantity of the different destination port numbers to a quantity of the connections, and determines that the connections include at least one point to point connection if the calculated ratio is larger than a predetermined ratio. The network device further determines that one of the connections is the point to point connection upon the condition that a communication protocol of the one of the connections is the transmission control protocol, that the destination port number of the one of the connections is larger than a predetermined port number, and that the average size of the packets of the one of the connections is larger than the predetermined size.
