Abstract: A device, a switch, and a method of determining latency which exceeds a threshold are described. A task is enqueued and a time is determined based on two clocks. A time the task is dequeued is determined based on the two clocks. Based on the time of enqueue and the time of dequeue according to each of the two clocks, the task is identified as meeting or violating a service level agreement.

Abstract: A network element includes circuitry and multiple ports. The multiple ports are configured to connect to a communication network. The circuitry is configured to receive via one of the ports a packet that originated from a source node and is destined to a destination node, the packet including a mark that is indicative of a cumulative state derived from at least bandwidth utilization conditions of output ports that were traversed by the packet along a path, from the source node up to the network element, to select a port for forwarding the packet toward the destination node, to update the mark of the packet based at least on a value of the mark in the received packet and on a local bandwidth utilization condition of the selected port, and to transmit the packet having the updated mark to the destination node via the selected port.

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: 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 networking device and system are described, among other things. An illustrative system is disclosed to include a shared buffer and at least a flow controller. In some embodiments, the system and/or flow controller may be configured to measure a packet flow's bandwidth consumption of the shared buffer, assign a flow-type attribute to the packet flow based on the packet flow's bandwidth consumption of the shared buffer, select a shared buffer schema for the packet flow based on the flow-type attribute assigned to the packet flow, and apply the selected shared buffer schema to the packet flow. For example, the flow-type attribute assigned to the packet flow may comprise a mice flow state or an elephant flow state, and a reserve attribute may be assigned to the flow based on the packet flow being assigned the mice flow state or the elephant flow state.

Abstract: A network element includes one or more ports and a packet processor. The one or more ports are to transmit and receive packets over a network. The packet processor is to apply a plurality of rules to the packets, each rule specifying (i) expected values for each header field of a group of header fields of the packets, including, for a given header field in the group, at least a set of multiple expected values, (ii) a group ID associated with the set, and (iii) an action to be applied to the packets whose header fields match the expected values.
