A controller includes one or more ports and a processor. The one or more ports are to communicate with a network that includes multiple network devices. The processor is to receive, from a network device in the network, a request to perform a software update in the network device, to evaluate a permission condition in response to the request, to send to the network device a response granting the request when the permission condition is met, and to at least temporarily deny the request when the permission condition is not met.

In-service software update managed by network controller

A network adapter includes a host interface, a network interface, a packet processor, and a telemetry handler. The host interface is to communicate with a host. The network interface is to send packets to a network. The packet processor is to process the packets prior to sending the packets to the network. The telemetry handler is to receive from the host, over the host interface, an indication specifying a flow or application, to mark one or more packets associated with the flow or application with a specified identifier in response to the indication, and to send the marked packets using the packet processor to the network via the network interface.

Flow/application-based packet marking by network-adapter

Methods, systems, and computer program products to generate a telemetry pipeline. In embodiments, the system includes a communication interface that receives one or more user-defined functions for the telemetry pipeline. The system also includes control logic that implements programmatically the one or more user-defined functions to collect telemetry data at a plurality of layers in the telemetry pipeline based on the one or more user-defined functions and calculate smart metrics at different layers of the plurality of layers in the telemetry pipeline. The smart metrics may be calculated at a layer closest to where associated telemetry data is collected.

Telemetry data abstraction

Processors, systems and methods are described that synchronize clocks of devices on a second network that uses a second network protocol to a source clock on a first network that uses a first network protocol. Processors, systems and methods are described to cause a first time synchronization message corresponding to a first network communication protocol to be converted to a second time synchronization message corresponding to a second network communication protocol to enable synchronization.

Time synchronization message conversion

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.

Reliable credit-based communication over long-haul links

Methods and systems include a hardware abstraction layer to provide control of two or more network switch controllers as a single network switch controller.

Port management in multi-ASIC systems

An electronic device connectable to a network interface device having a plurality of signal lanes may include a first computing device, a second computing device, and an interface to connect the first computing device to a first subset of signal lanes of the plurality of data lanes of the network interface device and connect the second computing device to a second subset of data lanes of the plurality of data lanes of the network computing device.

Electronic device and method for sharing data lanes of a network interface device between two or more computing devices

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.
