An automatic test device is disclosed. The automatic test device is includes connection ports, a processor, and a transmission integrated interface. The connection ports is configured to couple to a device under test. The processor is coupled to the connection ports and is configured to transmit a test instruction through the connection ports to the device under test. The device under test is in a test mode after receiving the test instruction, and the first processor is configured to receive a test signal transmitted through the connection ports from the device under test when the device under test is in the test mode. The transmission integrated interface is coupled between the connection ports and the processor, and is configured to transmit at least one of the test instructions to the connection ports or the processor. An automatic test system is also disclosed herein.

Methods and apparatus for mediating user access to services over a network are described. Access is provided by a service network host to a plurality of connectors providing access to a plurality of services over the network. The services are provided by entities independent from the service network host. The connectors including a first connector are configured to communicate with a first service using a first format to retrieve or modify data associated with the first service. The first connector is further configured to identify one or more methods or data fields of the first service. The service network host is further configured to provide, to a computer associated with a user over the network, one or more directions for using the first connector to display and/or modify data from the first service over the network.

In a data processing method, a timeout aggregation node of a cluster obtains first data that is partial aggregated data in a data-intensive computing task. The first data carries a first identifier of a timeout node indicating that a timeout occurs on the timeout node. The timeout aggregation node obtains second data of the timeout node based on the first identifier, where the second data is to-be-aggregated data sent by the timeout node. The timeout aggregation node aggregates the first data and the second data according to a preset rule to obtain third data that is complete aggregated data. The timeout aggregation node then notifies each computing node in the cluster of the third data.

A network switch is capable of supporting cut-through switching and interface channelization with enhanced system performance. The network switch includes a plurality of ingress tiles, each tile including a virtual output queue (VOQ) scheduler operable to submit schedule requests to a fabric scheduler. Data is requested in unit of quantum, which may aggregate multiple packets, and which reduces schedule latency. Each request is associated with a start-of-quantum (SoR) state or a middle-of-quantum (MoR) state to support cut-through. The fabric scheduler performs a multi-stage scheduling process to progressively narrow the selection of requests, including stages of arbitration in virtual output port level, virtual output port group level, tile level, egress port level, and port group level. Each tile receives the grants for its requests and accordingly sends request data to a switch fabric for transmission to the destination egress ports.

A method and system of configuring a stack of switches includes configuring a switch with mapping information based on a user input flow mapping that defines destination port(s) (local destination port(s) and/or remote destination port(s)) for a flow to exit the stack. The mapping information includes any local destination port(s) via which the flow can exit the stack from the switch and an outbound stack port for each of any remote destination port(s) via which the flow can be transmitted from the switch to a downstream switch. The method further includes creating a decapsulation entry having a flow ID for the flow, wherein the flow ID is assigned to the flow and is unique across the stack, and configuring the switch with access to a decapsulation algorithm configured to use the flow ID via the decapsulation entry to decapsulate encapsulated network traffic of the flow received from an upstream switch.

Examples disclosed herein relate generally to providing frames at a network port. Some examples relate to an apparatus. The apparatus may include a network port to directly couple the apparatus to a switch. The apparatus may also include a transmission logic to provide a frame at the network port at a time slot of a switch-associated cycle time. The transmission logic may provide the frame at the time slot at least partially responsive to an offset value and a port number. Related devices, systems and methods are also disclosed.
