Abstract

First data indicative of information that a packet is part of a DDoS attack is received at a management network device. A DDoS remediation network device to be used for remediation of packets associated with the DDoS attack is determined from the first data. Second data, indicative of the DDoS attack and indicative of the DDoS remediation network device, is transmitted from the management network device to an edge network device. The second data is configured to cause the edge network device to route packets associated with the DDoS attack to the DDoS remediation network device.
