Abstract: A network device, system-on-a-chip, and method of performing an auto-negotiation for a planarized computing system. In response to a link request, switching hardware determines whether a source of the link request is planarized or non-planarized. If a mismatch between a received link request and a sent link request occurs, a lower-level event is escalated to the operating system which is enabled to respond to continue the auto-negotiation process.

Abstract: A system for implementing a multiplane network comprises a network device including a plurality of switches for routing traffic to an endpoint through a network of other switches. Each switch in the plurality of switches corresponds to a different plane of the multiplane network. The system includes one or more circuits that manages the plurality of switches as a single logical entity.

Abstract: A power allocation method includes allocating power-consumption allocations to multiple processing devices. Available power allocations, which are offered for transfer to other processing devices, are reported by one or more over-allocated processing devices among the processing devices. Power demands, which are required by one or more under-allocated processing devices among the processing devices, are reported by the under-allocated processing devices. At least some of the available power allocations are transferred from one or more of the over-allocated processing devices to one or more of the under-allocated processing devices.

Abstract: A controller includes an interface and a processor. The interface is to communicate with multiple processing devices. The processor is to determine respective amounts of available electrical power that are available in the processing devices for executing jobs, to select a group of one or more of the processing devices for executing a new job, based at least on (i) the amounts of available electrical power and (ii) an expected power demand needed for executing the new job, and to assign the selected group to execute the new job.

Abstract: 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. The network device issues the request in response to an instruction from a Network Management System (NMS) that is separate from the controller.

Abstract: An apparatus includes an interface and a processor. The interface is to receive telemetry data items obtained from one or more network adapters and from one or more network switches of a network, the telemetry data items pertaining to respective packets and including respective identifiers of flows or applications with which the packets are associated. The processor is to analyze the telemetry data items using the identifiers.
