Abstract: Switches for performing packet switching and associated methods are provided. An example switch includes an ingress port for receiving a packet. The switch includes a plurality of egress ports for discharging the packet from the switch. The switch includes a plurality of egress queues with each egress queue associated with one of the plurality of egress ports. The switch includes a control plane configured to determine a descriptor associated with a packet, determine a first egress port from which to discharge the at least one packet and to transmit the descriptor to an egress queue associated with the first egress port. The switch includes a descriptor crossbar configured to transmit the descriptor from the egress queue to a second egress port of the plurality of egress ports. The switch includes a packet crossbar configured to transmit the at least one packet from the ingress port to the second egress port.

Abstract: A network device includes processing circuitry and one or more ports. The one or more ports are configured to connect to a communication network. The processing circuitry is configured to receive a packet originating from a network node running an application program, the packet includes application-level metadata relating to the application program, to generate telemetry data based at least on the application-level metadata, and to transmit the telemetry data via one of the ports, over the communication network.

Abstract: A communication apparatus includes input circuitry, an encapsulator, transmission circuitry and flow control circuitry. The input circuitry is to receive packets from a data source in accordance with a first communication protocol that employs credit-based flow control. The encapsulator is to buffer the packets in a memory buffer and to encapsulate the buffered packets in accordance with a second communication protocol. The transmission circuitry is to transmit the encapsulated packets over a communication link in accordance with the second communication protocol. The flow control circuitry is to receive from the encapsulator buffer status indications that are indicative of a fill level of the memory buffer, and to exchange credit messages with the data source, in accordance with the credit-based flow control of the first communication protocol, responsively to the buffer status indications.
