Abstract:
Apparatus and methods for mitigating network attacks, such as by dynamically re-routing traffic. Various disclosed embodiments manipulate path-based routing of the backbone network to insert a scrubbing appliance within the backbone network topology, rather than using traditional network addressed tunnels in the edge network. In one implementation, traffic entering the backbone network ingress peer routers (from either another backbone network, or an edge network) is normally destination-address routed via the backbone to its appropriate egress router based on a path label; however, when a Distributed Denial of Service (DDoS) attack is detected, the ingress peer router inserts an additional hop into the path label that redirects dirty traffic to a substantially centralized scrubbing appliance. The benefits of the disclosed solutions include, among other things, significantly reduced attack response/recovery times without significant capital outlays.
