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 device includes one or more ports, and action-select circuitry. The ports are to exchange packets over a network. The act-ion-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: 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 a memory and a memory management circuit. The memory is to store a shared buffer. The memory management circuit is to estimate respective bandwidth measures for one or more queues used in processing packets in the network device, and to allocate and deallocate segments of the shared buffer to at least one of the queues based on the bandwidth measures.

Abstract: An apparatus for controlling a Shared Buffer (SB), the apparatus including an interface and a SB controller. The interface is to access flow-based data counts and admission states. The SB controller is to perform flow-based accounting of packets received by a network device coupled to a communication network, for producing flow-based data counts, each flow-based data count associated with one or more respective flows, and to generate admission states based at least on the flow-based data counts, each admission state being generated from one or more respective flow-based data counts.

Abstract: A system, switch device, and method of operating a switch device are provided. An illustrative system is disclosed to include a first router block configured to receive a first type of Remote Direct Memory Access (RDMA) packet, a second router block configured to receive a second type of RDMA packet, and a gateway positioned between the first router block and the second router block. The gateway may be configured to translate the first type of RDMA packet received from the first router block for transmission as the second type of RDMA packet by the second router block.

Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving via an ingress interface packets that are not allowed to undergo re-routing and that are addressed to a destination via a first egress interface. The packets are forwarded via the first egress interface when there is a valid path from the first egress interface to the destination. When there is no valid path from the first egress interface to the destination, a second egress interface is selected from a group of multiple egress interfaces that have respective paths to the destination and are assigned to packets for which re-routing is allowed, and the packets are forwarded via the second egress interface until recovering a path to the destination.
