METHOD, APPARATUS AND SOFTWARE FOR NETWORK TRAFFIC MANAGEMENT

摘要

A network traffic evaluation device is provided that may be used to warn of or prevent trafficabnormalities such as denial of service attacks. The device includes a data interface to receive one or both of network traffic and data indicative of characteristics of network traffic. The network traffic and/or data received by the data interface is processed for predeterminedcharacteristics that indicate that the network traffic contains a subset of attack traffic. Upon detection of the predetermined characteristics information defining a superset is provided. The superset is a portion of the network traffic that contains the subset and defines network traffic that may be redirected and/or blocked by a network device.
