摘要： A packet being processed by a network device is parsed by a programmable processing unit executing computer readable instructions stored in a non-transitory computer readable storage medium. Parsing the packet includes identifying one or more protocol layers within a header of the packet, identifying respective locations of protocol headers within the header of the packet, and providing the respective identified locations of protocol headers within the header of the packet to a hardware key generator block. A lookup key corresponding to the packet is generated by the key generator block using the respective identified locations. Generating the lookup key includes extracting, using an identified location of a protocol header, one or more fields from the corresponding protocol header. The lookup key is provided to a lookup engine. A lookup operation with respect to the packet is performed by the lookup engine and based on the lookup key.

摘要： One or more processing operations with respect to a packet are performed at a packet processing node of a network device, the packet processing node configured to perform multiple different processing operations with respect to the packet. A first accelerator engine is triggered for performing a first additional processing operation with respect to the packet. The first additional processing operation constitutes an operation that is different from the multiple different processing operations that the packet processing node is configured to perform. The first additional processing operation is performed by the first accelerator engine. Concurrently with performing the first additional processing operation at the first accelerator engine, at least a portion of a second additional processing operation with respect to the packet is performed by the packet processing node, the second additional processing operation not dependent on a result of the first additional processing operation.
