US11757932B2 Event driven route control
Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.
