摘要： Embodiments of the invention include a method performed in a packet processor core for policing a packet through a hierarchical policer coupled to one or more policing requestors. The hierarchical policer has a plurality of meter levels including an initial level and one or more subsequent levels. The hierarchical policer creates a meter result at the meter of each meter level using packet characteristics and a meter state for that meter level. The hierarchical policer generates meter level outputs that classify the packet for each meter level and for at least one of the subsequent levels the meter level output is based on the meter level output from a previous meter level. The hierarchical policer performs a meter combine operation that produces a final packet output attribute from the combination of the meter level outputs. The hierarchical policer returns the final packet output attribute to a policing requestor.

摘要： Embodiments of the invention include a method for avoiding memory bandwidth utilization during packet processing. The packet processing core receives a plurality of packets. The packet processing core identifies the packet's quality of service (QoS) descriptor. The packet processing core determines that at least one packet should be moved to an off-chip packet stored prior to the packet being transmitted to the egress port. The packet processing core bases that determination, at least in part, on the packet's QoS descriptor. The packet processing core moves the determined packets to the off-chip packet store. The packet processing core determines that at least one packet should not be moved to the off-chip packet store prior to the packet being transmitted to the egress port. This determination is also made, at least in part, based on the packet's QoS descriptor.

摘要： Embodiments of the invention a method for policing a packet at line rate. A hierarchical policer receives a policer request comprising packet characteristics and identifying request configuration information. The hierarchical policer retrieves meter states specified by the request configuration information. The hierarchical policer processes packet characteristics through meters to generate a meter result. The hierarchical policer generates a hierarchical policer table lookup address using a plurality of meter types, a plurality of input color controls, one or more of the packet characteristics, the meter results, and a plurality of coupling algorithm identifiers. The hierarchical policer reads a hierarchical meter result from a hierarchical policer result table, containing at least a final output packet attribute that classifies the packet. The hierarchical policer updates one or more of the meter states based on the plurality of meter state results. The hierarchical policer returns the final packet output to a policing requestor.
