20140169378 | MAINTAINING PACKET ORDER IN A PARALLEL PROCESSING NETWORK DEVICE - A plurality of packets are received by a packet processing device, and the packets are distributed among two or more packet processing node elements for processing of the packets. The packets are assigned to respective packet classes, each class corresponding to a group of packets for which an order in which the packets were received is to be preserved. The packets are queued in respective queues corresponding to the assigned packet classes and according to an order in which the packets were received by the packet processing device. The packet processing node elements issue respective instructions indicative of processing actions to be performed with respect to the packets, and indications of at least some of the processing actions are stored. A processing action with respect to a packet is performed when the packet has reached a head of a queue corresponding to the class associated with the packet. | 06-19-2014 |
20140215144 | ARCHITECTURE FOR TCAM SHARING - Aspects of the disclosure provide a packet processing system. The packet processing system includes a plurality of processing units, a ternary content addressable memory (TCAM) engine, and an interface. The plurality of processing units is configured to process packets received from a computer network, and to perform an action on a received packet. The action is determined responsively to a lookup in a table of rules to determine a rule to be applied to the received packet. The TCAM engine has a plurality of TCAM banks defining respective subsets of a TCAM memory space to store the rules. The interface is configured to selectably associate the TCAM banks to the processing units. The association is configurable to allocate the subsets of the TCAM memory space to groups of the processing units to share the TCAM memory space by the processing units. | 07-31-2014 |
20150110113 | PACKET PARSING AND KEY GENERATION IN A NETWORK DEVICE - 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. | 04-23-2015 |
20150110114 | Processing Concurrency in a Network Device - 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. | 04-23-2015 |
20150113190 | Processing Concurrency in a Network Device - A processing unit of a packet processing node initiates a transaction with an accelerator engine to trigger the accelerator engine for performing a processing operation with respect to a packet, and triggers the accelerator engine to perform the processing operation. The processing unit attempts to retrieve a result of the first processing operation from a memory location to which a result is to be written. It is determined whether the result has been written to the memory location, and when it is determined that the result has not yet been written to the memory location, the processing unit is locked until at least a portion of the result is written to the memory location. | 04-23-2015 |
