<p>A computer system (10) includes an end system (40), a bus (50), a communications interface (60), and a bus interface (110). The bus (50) is coupled to the end system (40). The communications interface (60) is coupled to the bus (50) and includes a physical layer (70), a receive buffer (100), and a channel control unit (120). The physical layer (70) is adapted to receive an input signal and demodulate the input signal to generate a plurality of cells. The receive buffer (100) is adapted to receive the cells. The channel control unit (120) is adapted to identify extraneous cells in the receive buffer and discard the extraneous cells. The bus interface (110) is coupled to the bus (50) and is adapted to receive the remaining cells from the channel control unit (120) and transfer the remaining cells over the bus (50) to the end system (40). A method for reducing traffic on a bus (50) coupling an end system (50) to an interface is provided. An input signal is received. The input signal is demodulated to generate a plurality of cells. Extraneous cells in the plurality of cells are identified. The extraneous cells are discarded. The remaining cells are transfered over the bus (50) to the end system (40).</p> |
