1. A method for conveying data over a packet-switching network, comprising:

  • receiving data from a peripheral device for transmission via the network to a memory associated with a central processing unit (CPU);

    receiving an interrupt signal from the peripheral device associated with the data;

    sending one or more data packets containing the data over the network to a host network interface serving the memory and the CPU; and

    sending an interrupt packet over the network to the host network interface, responsive to which an interrupt input of the CPU is asserted only after the one or more data packets have arrived at the host network interface, wherein sending the interrupt packet comprises reading a cause of the interrupt from the peripheral device, and incorporating the cause in the interrupt packet.
