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 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: A device, communication system, and method are provided. In one example, a system for routing traffic is described that includes a plurality of ports to facilitate communication over a network. The system also includes a controller to determine, for a first port of a plurality of ports, a bandwidth for the first port and a bandwidth history for the first port, compare the bandwidth for the first port and the bandwidth history for the first port to a threshold, and alter a configuration of the first port based on the comparing of the bandwidth and the bandwidth history to the threshold.

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 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.

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 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: 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.
