Abstract:
A method and apparatus of a network element that installs a control plane data rule from system memory to specialized hardware memory in a network element is described. In an exemplary embodiment, the network element receives control plane data processing statistics of control plane data that is received by the network element, where the control plane data is policed using a plurality of control plane data policing rules stored in the system memory. The network element further determines that a candidate policing rule is being utilized greater than a threshold based on at least the control plane data processing statistics, where the candidate policing rule is one of the plurality of control plane data policing rules stored in the system memory. The network element additionally installs the candidate policing rule in the specialized hardware memory, where the candidate policing rule is subsequently used by the network element to police the control plane data.
