Abstract
Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, and mechanisms, for a route processor adjusting admission control policies for packets destined for the route processor and enforced on line cards. Individual line cards can identify offending packet flows that pass through them. However, for example, it is possible that an attack on the route processor might comprise packets being forwarded to the route processor from different line cards, with these packets belonging to a same or different packet flow. By monitoring and identifying offending packet flows, the route processor can inform at least the line cards corresponding to these offending packet flows in order to adjust their corresponding admission control policies to combat such an attack, while typically allowing legitimate traffic to continue to flow at the desired rate to the route processor.
