A method of communicating with two or more slaves is provided. The method includes receiving a command packet with an interface, wherein the command packet is sent by a master over a master-slave bus and associating a slave address of the command packet with one of two or more slaves communicatively coupled to the interface.

A computing apparatus, including at least one general computing core circuit, an internal interface circuit, an external interface circuit, a cache coherence engine circuit, and a protocol conversion circuit. The computing apparatus is coupled to an internal apparatus using the internal interface circuit, and is coupled to an external apparatus using the external interface circuit. When working in a first mode, the cache coherence engine circuit implements cache coherence between the computing apparatus, the internal apparatus, and the external apparatus, and in this case, the computing apparatus is used as a node controller. When working in a second mode, the cache coherence engine circuit processes only cache coherence between the computing apparatus and the internal apparatus, and the external interface circuit is used as a network interface circuit.

In an embodiment of the present invention, a method receives, at a first node of multiple nodes, each node connected to a common network bus, a health message from a second node. The health message includes a log of health messages from other nodes. Each node sends health messages at a frequency known to the plurality of nodes. The method further compares, at the first node, the log of messages from other nodes in the received health message to a log of health messages previously received from other nodes stored by the first node. Based on the comparison, determining a health status of each node. Using embodiments of the present method and system, computing units can form dynamic fault-tolerant groups.

The invention relates to a method for managing configuration of an industrial internet field broadband bus, the method being applicable to a two-wire data transfer network in which a bus controller and respective bus terminals are synchronized in clock, and the bus controller allocates time slices for the respective bus terminals and the bus controller, so that the bus controller firstly acquires the configuration information, and determines the bus terminal corresponding to the configuration information, and then the bus controller transmits the configuration information to the bus terminal in the time slice occupied by the bus controller, when the bus controller need transmit configuration information to the respective bus terminals, to thereby make the bus terminal perform corresponding configuration operations according to the configuration information.

A computing device that forms a group in accordance with a peer-to-peer protocol in which a device may be identified based on a credential of a user. The credential may be used to determine a unique identifier for the user such that the same identifier is used on any device operated by the same user. Such an identifier may be used in connection with a peer-to-peer protocol that supports persistent peer-to-peer groups. As a result, the unique identifier for the user may be retained by remote devices that have paired with any device operated by a particular user such that those remote devices may automatically establish a connection with any other device operated by the same user that similarly uses the same unique identifier for the user.

A system of embedding access control logic into a network gear according to an embodiment includes a plurality of access control devices including corresponding lock mechanisms configured to control access through corresponding passageways, a headend access control system configured to manage access control data associated with the plurality of access control devices, and a network switch communicatively coupled to the headend access control system and comprising a smart communication manager, wherein the smart communication manager includes an application programming interface accessible by the headend access control system and translates commands received from the headend access control system into payloads readable by the plurality of access control devices.

In some examples, a transport agnostic source includes a streaming device to stream video on diverse transport topologies including isochronous and non-isochronous transports. In some examples, a transport agnostic sink includes a receiving device to receive streamed video from diverse transport topologies including isochronous and non-isochronous transports.
