Abstract
An apparatus is equipped to receive network traffic data for network traffic routed over one or more network links relevant to a network link. Selected numbers of analysis are performed to determine if the network link of interest is being misused. The analyses include but are not limited to analyses to determine whether the network traffic routed are inconsistent with an expected traffic pattern, whether unallocated source addresses are present, whether source addresses exhibit an uncharacteristic even distribution pattern, whether a server is uncharacteristically excessive in responding to the same source address, whether normal bursty behavior is absent from the traffic, whether a ratio of packets in one direction to packets in another direction is out of balance, whether a ratio of packets of one type to packets of another type is out of balance, and whether a server is uncharacteristically excessive in responding with error responses.
