ABSTRACT:
An error handling apparatus and method, and a computer-readable medium storing a computer program for executing the error handling method are provided. According to the method, in a case where a number of errors in object IP packets that are consecutively detected, each within a first predetermined time since a previous error detection, exceeds a maximum allowable number of errors, communication with a sending node of the erroneous IP packets during a second predetermined time is discontinued. Also, errors can be handled with reference to a cache unit including more than one entry identified by an address of a corresponding erroneous IP packet. Therefore, a network load of a receiving node can be reduced by not transmitting an internet control message protocol (ICMP) packet to a sending node where indiscriminate IP packet manipulations or denial of service (DoS) attacks are suspected during the second predetermined time.
