Abstract
A system and method for mitigating a denial of service attack in a subscriber network. A traffic monitor monitors bandwidth usage of a subscriber network that is directed to a particular port. The traffic monitor detects excessive traffic based on preset thresholds or algorithms. When excessive traffic is detected, the traffic monitor may obtain the source IP address from headers in the packet stream and identify the device or devices from which the packets were delivered to the network. Using the IP addresses of affected devices, a policy may be implemented to throttle packets originating from those devices that are directed to the particular port.
