ABSTRACT:
A data relay device transmitting received unit data has an external interface unit, a main control unit, where the received unit data are received from outside the data relay device and transmitted to the corresponding destination memory not through the main control unit. The external interface unit is equipped with memory in the external interface, the threshold setting unit, and the external control unit. The main control unit receiving the threshold receiving notice reads the information in the corresponding field of the received unit data stored in the memory in the external interface and judges whether the received unit data should be transmitted, or not. The main control unit deletes the received unit data judged to be unnecessary before the transmitting.
