  • Patent number: 7814224
    Abstract: An information processor disclosed herein prevents adverse impacts on higher priority processing due to extremely frequent receive processing when inbound traffic from a network is over-traffic state (under a DoS attack). The information processor attached to a network collects information about traffic state and, if it is determined that over-traffic state is present, deactivates the communication processing function without passing an interrupt request due to communication to the data processing block. In this state, the information processor continues to collect information about traffic state and, when it is determined that over-traffic state has terminated, starts to transfer an interrupt request to the data processing block and makes the communication processing function recover.
