Abstract
A method, apparatus and network device for controlling the flow of network data arranged in frames and minimizing congestion is disclosed. A status error indicator is generated within a receive FIFO memory indicative of a frame overflow within the receive FIFO memory. In response to the status error indicator, an early congestion interrupt is generated to a host processor indicative that a frame overflow has occurred within the receive FIFO memory. The incoming frame is discarded and the services of received frames are enhanced by one of either increasing the number of words of a direct memory access (DMA) unit burst size, or modifying the time-slice of other active processes.
