Abstract: A parsing apparatus includes an interface, a first parser, a second parser and a controller. The interface is configured to receive packets belonging to a plurality of predefined packet types. The first parser is configured to identify any of the packet types. The second parser is configured to identify only a partial subset of the packet types. The controller is configured to receive a packet via the interface, to attempt identifying a packet type of the received packet using the second parser, and in response to detecting that identifying the packet type using the second parser fails, to revert to identify the packet type of the received packet using the first parser.

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 element includes circuitry and one or more interfaces. The interfaces are configured to connect to a communication network. The circuitry is configured to assign multiple egress interfaces corresponding to respective different paths via the communication network for routing packets to a given destination-address group, to hold, for the given destination-address group, respective state information for each of multiple sets of hash results, to receive via an ingress interface a packet destined to the given destination-address group, to calculate a given hash result for the packet and identify a given set of hash results in which the given hash result falls, and to forward the packet via one of the multiple egress interfaces in accordance with the state information corresponding to the given destination-address group and the given set of hash results.

Abstract: Networking devices, systems, and methods are provided. In one example, a method includes receiving a packet at a networking device; evaluating the packet; based on the evaluation of the packet, truncating the packet from a first size to a second size that is smaller than the first size; and storing the truncated packet in a buffer prior to transmitting the truncated packet with the networking device.

Abstract: A network device includes one or more ports, and action-select circuitry. The ports are to exchange packets over a network. The action-select circuitry is to determine, for a given packet, a first search key based on a first header field of the given packet, and a second search key based on a second header field of the given packet, to compare the first search key to a first group of compare values, to output a multi-element vector responsively to a match between the first search key and a first compare value, to generate a composite search key by concatenating the second search key and the multi-element vector, to compare the composite search key to a second group of compare values, and, responsively to a match between the composite search key and a second compare value, to output an action indicator for applying to the given packet.

Abstract: An apparatus includes an input interface to receive incoming packets from a first network device and an output interface to send outgoing packets to a second network device. Media access control security (MACsec) circuitry is coupled between the input interface and the output interface. Bypass flow-control (FC) circuitry is coupled between the input interface and the MACsec circuitry. The bypass FC circuitry is to detect an FC packet in the incoming packets and pass the FC packet passively to the output interface to enable end-to-end flow control directly between the first network device and the second network device.

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: A network device includes multiple ports, packet processing circuitry, a memory and a reserved-memory management circuit (RMMC). The ports are to communicate packets over a network. The packet processing circuitry is to process the packets using a plurality of queues. The memory is to store a shared buffer. The RMMC is to allocate segments of the shared buffer to the queues, including allocating reserve segments of the shared buffer to selected queues that meet a reserve-allocation criterion.

Abstract: A network device includes processing circuitry and a plurality of ports. The ports connect to a communication network. The processing circuitry is configured to receive, via an input port, data packets and probe packets that are addressed to a common output port, to store the data packets in a first queue and the probe packets in a second queue, both the first queue and the second queue are served by the output port, to produce telemetry data indicative of a state of the network device, based on a processing path that the data packets traverse within the network device, to schedule transmission of the data packets from the first queue at a first priority, and schedule transmission of the probe packets from the second queue at a second priority higher than the first priority, and to modify the scheduled probe packets so as to carry the telemetry data.
