    abstract =  {Control Plane Policing (CoPP), as described in RFC 6192, classifies control-plane-destined traffic using static packet header fields. This static classification cannot distinguish legitimate protocol traffic from attack traffic that matches the same header-based rules. This document specifies Stateful CoPP, an operational practice in which the router's runtime protocol state -- including configured peer identities, session state, and expected ingress interfaces -- is incorporated into CoPP classification. Stateful CoPP allows confirmed legitimate traffic to receive preferential access to control plane CPU resources under attack conditions.},
