1. In a data communications device having multiple network interfaces which are capable of transmitting and receiving data elements with a network, a method comprising the steps of:

  • A. determining which of the multiple network interfaces indicates readiness to transmit a data element to the network and which of the multiple network interfaces indicates receipt of a data element from the network;

    B. running, for each network interface indicating readiness to transmit a data element to the network, a transmit interrupt handler to load that network interface with a data element for transmission if such a data element is available for transmission within the data communications device, in response to giving higher priority to handling transmit interrupts relative to handling receive interrupts; and

    C. after step B, running, for at least one network interface which indicates receipt of a data element from the network, a receive interrupt handler to process that data element.
