<p><P>PROBLEM TO BE SOLVED: To detect a packet loss of a fragment packet in real time. <P>SOLUTION: A receiving part 11 receives a fragment packet, a packet processing part 13 determines whether the fragment packet is the last fragment packet, and when any fragment packets are not received upon receiving the last fragment packet and when unreceived fragment packets can not be received within a prescribed time, a packet loss determining part 14 determines that the packet loss has occurred. Consequently, it is possible to detect a packet loss in real time while taking into consideration the switching of arrival orders of the fragment packets. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
