Abstract

Communication controller (3), for buffering data packets, interfaceable with a host processor (I) and a communication medium control unit (2) employing packet numbers assignment storing in a transmit queue (9) and a receive queue (10). Each transmitted or received data packet is assigned a unique packet number (N Ti, N Rj) and dynamically allocated buffer storage (6) by a memory management unit (7) transparent to both the host processor (1) and the control unit (2). The packet number is stored in a packet number queue (9, 10) with pointers corresponding to the physical addresses where the data packet is stored. Mechanism is provided to interrupt the host processor (1) upon completion of any preselected number of data packet transmission.
