ABSTRACT:
An information processing apparatus (1) is equipped with: a history packet transmitting unit (11) for transmitting a history packet via a communication processing apparatus (2); a request packet transmitting unit (12) for transmitting a request packet which requests a transmission of a return packet; a packet transmission control unit (13) for controlling the transmission of the request packet; a return packet receiving unit (14) for receiving the return packet transmitted from a server apparatus (3); and a port keeping time detecting unit (15) for detecting a port keeping time of the communication processing apparatus (2) based upon the reception of the return packet by the return packet receiving unit (14). The server apparatus (3) is comprised of: a request packet receiving unit (31) for receiving the request packet; and a return packet transmitting unit (32) for transmitting the return packet to a port of the communication processing apparatus (2) when the request packet receiving unit (31) receives the request packet. With employment of the above-described arrangement, an information processing system capable of detecting the port keeping time of the communication processing apparatus is provided.
