Abstract

See full text

A communication control apparatus connected between a transmission path and a processing unit which apparatus includes a table memory for storing the number of received frames which are in the state waiting for protocol processing in correspondence with connection identifiers, a first processor responsive to reception of a new frame from the aforementioned transmission path for making decision by referencing the memory table mentioned above as to whether or not the number of the received frames corresponding to the connection identifier of the newly received frame and waiting for the protocol processing has reached a threshold value for thereby abandoning the aforementioned newly received frame when that number has reached the threshold value and, if otherwise, placing the newly received frame in the state waiting for the protocol processing, and a second processor for executing a predetermined protocol processing on the received frame in the state waiting for the protocol processing.
