Abstract: A networking device and system are described, among other things. An illustrative system is disclosed to include a packet parser and a state machine that includes a NULL header state. The packet parser references the state machine to enter the NULL header state automatically in response to parsing a packet header of a predetermined type and then, while in the NULL header state, analyzes a subsequent set of bytes without advancing a parser pointer.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a bandwidth-constrained resource and a controller that dynamically allocates a proportional consumption of storage to the bandwidth-constrained resource thereby enabling the bandwidth-constrained resource to provide bandwidth to a consuming entity. The controller may allocate the proportional consumption of the storage to the bandwidth-constrained resource based on a current state of the bandwidth-constrained resource.

Abstract: A parsing apparatus includes a packet-type identification circuit and a parser. The packet-type identification circuit is to receive a packet to be parsed, and to identify a packet type of the packet by extracting a packet-type identifier from a defined field in the packet. The parser is to store one or more parsing templates that specify parsing of one or more respective packet types. When the packet type of the packet corresponds to a parsing template among the stored parsing templates, the parser is to parse the packet in accordance with the stored parsing template. When the packet type of the packet does not correspond to any of the stored parsing templates, the parser is to parse the packet using an alternative parsing scheme.

Abstract: A method for communication includes configuring a router to forward data packets over a network in accordance with Multiprotocol Label Switching (MPLS) labels appended to the data packets. At least first and second entries, corresponding to respective first and second labels, are stored in a Next Hop Label Forwarding Entry (NHLFE) table in the router, such that each of the first entries contains a respective pointer to at least one of the second entries. Upon receiving in the router a data packet from the network, a first entry is selected from among the first entries in the NHLFE table and, responsively to the pointer in the first entry, a second entry is selected. The respective first and second labels from the selected first and second entries are pushed onto an MPLS label stack of the data packet.

Abstract: A network device includes one or more ports, a packet processor, and a memory management circuit. The one or more ports are to communicate packets over a network. The packet processor is to process the packets using a plurality of queues. The memory management circuit is to maintain a shared buffer in a memory and adaptively allocate memory resources from the shared buffer to the queues, to maintain in the memory, in addition to the shared buffer, a shared-reserve memory pool for use by a defined subset of the queues, to identify in the subset a queue that (i) requires additional memory resources, (ii) is not eligible for additional allocation from the shared buffer, and (iii) meets an eligibility condition for the shared-reserve memory pool, and to allocate memory resources to the identified queue from the shared-reserve memory pool.

Abstract: An example method for dynamic packet routing using prioritized groups includes: receiving, by a processing device, routing information specifying a plurality of paths to a network destination, wherein each path is associated with a respective cost metric value; associating a first subset of the plurality of paths with a first priority routing group for the network destination, wherein each path of the first subset satisfies a first cost criterion based on a cost metric value of the path; associating a second subset of the plurality of paths with a second priority routing group for the network destination, wherein each path of the second subset satisfies a second cost criterion; and storing, in a forwarding information data structure, a first definition of the first priority routing group and a second definition of a second priority routing group.
