Line cards receive control packets and perform a hierarchical rate limiting on those control packets. A set of identifier keys are extracted from the control packets and the protocol of those control packets are determined. At a first level, the control packets are rate limited per unique set of identifier keys per protocol. Those packets which fail the first rate limiting level are dropped. Those packets which pass the first rate limiting level are rate limited at a second level per protocol type. Those packets which fail the second level rate limiting are dropped while those packets which pass the second level rate limiting are sent to the control card for further processing.

Hierarchical rate limiting of control packets

Techniques for multiple protocol cross layer customized QoS propagation and mapping are described herein. In one embodiment of the invention, a first QoS code of a packet is determined, the packet having a first encapsulation layer and a second encapsulation layer, the first QoS code being included within the first encapsulation of the packet. From application of a first cross layer QoS map to the first QoS code, determining that the second encapsulation layer of the packet should be used in determining a QoS classification. The reference point to the second encapsulation layer is stored. The QoS classification is determined with use of the reference point. A representation of the QoS classification is stored in a QoS descriptor and the QoS descriptor is used to influence processing of the packet. Other methods and apparatuses are also described.
