<p>A communication control device has a physical interface for physical interfacing with a network, a processor (1) for processing high rank communication protocol of a frame from the network, a receiving controller (4) for processing low rank communication protocol of the frame, and a communication buffer (2) for storing the frame in a sequence order received. In the device, at least one of the receiving controller has a controller setting each of the receiving controller into one of a communication processing state, a communication standby state, and a halt state, setting one of the receiving controller under the halt state into the communication standby state, and selecting a data structure and giving the selected data structure to the receiving controller under the communication standby state to process the following frame transferred from the network. The receiving controller under the communication standby state transits into the communication processing state in order to receive the frame and transits into the halt state after receiving completion. <IMAGE></p> |
