Abstract
A multiport network device includes output ports, internal rules checking logic, a port filter, and input ports. The input ports receive data frames and transfer the data frames to the internal rules checking logic and the port filter. The internal rules checking logic determines the appropriate output ports for the frame. At potentially the same time, the port filter determines priority information for the frame. The port filter informs the internal rules checking logic when it has completed determining the priority information by transmitting an end-of-frame signal to the internal rules checking logic. In response, if the internal rules checking logic has completed determining the output ports for the frame, it assembles a frame descriptor corresponding to the frame and transmits the frame descriptor to the appropriate output port(s).
