<p>When a packet transmitting means (21) transmits a request packet, a predicting means (23) predicts a response packet which is expected to be received in response to the request packet, so that a packet receiving means (22) can surely receive the response packet. When the means (22) receives a response packet from a transmission medium (25), a comparing means (26) compares the packet received by the receiving means (22) with part of the response packet predicted by the predicting means (23) and, only when the packets are coincident with each other, outputs the received packet. Therefore, the reliability of the transmission medium (25) can be improved, because it becomes possible to surely receive the response packet which is expected to be received by only receiving the response packet preferentially.</p> |
