Embodiments relate to a billboard circuit that stores context information received from various component circuits in an electronic device. The context information indicates an operating status of the corresponding component circuit, system or shared resources. The stored context information may be retrieved by one or more component circuits when events (e.g., turning on of a component circuit) are detected. By using the billboard circuit, a component circuit may detect changes in the operating status of other components circuits and configure or update its operations even when the changes occurred while the component circuit was asleep or disabled. The billboard circuit may monitor updating of the context information by the component circuit and initiate notification to other components circuits when certain entries of the context information is updated.

A method for operating a first network device of a communications network, wherein the method comprises: determining or receiving, by means of an ingress interface, an ingress data stream comprising payload data to be transmitted towards a second network device; determining or receiving, by means of a correlation observer, at least one correlation value for a plurality of communication paths between the first network device and the second network device, wherein each of the plurality of communication paths comprises a different one of a plurality of physical channels; determining, by means of a multi-connectivity controller, a plurality of egress data streams in dependence on the at least one correlation value and in dependence on the ingress data stream; and transmitting, via a respective one of a plurality of egress queues, wherein each egress data stream is associated with a different one of the plurality of paths.

A data collection method and apparatus, a Modbus system, and a storage medium, and pertain to the field of communication technologies. In embodiments, one or more pieces of block data are collected at one-time interaction between a master and a slave, and a maximum amount of data carried in each piece of block data is 256. In the Modbus system, one piece of data is represented in a minimum of 1 byte, so that the data carried in each piece of block data can be up to 256 bytes. If a plurality of pieces of block data are collected at one-time interaction, an amount of data that can be collected is much larger than 252 bytes limited in a protocol. That is, in the embodiments, a larger amount of data can be collected at one-time interaction.

A process detects anomalies on a controller area network (CAN) bus. An arbitration field in a message on the CAN bus is analyzed, and a data field in the message on the CAN bus is inspected. The process further monitors a frequency of message identifiers that are transmitted across the CAN bus, and determines that an overall bus load crosses a threshold. The process then transmits an alert when the analyzing the arbitration field, the inspecting the data field, the monitoring the frequency, and the determining the overall bus load indicate that an anomaly has occurred on the CAN bus.

A network node for coupling to a communication bus, the node comprising: a receiver configured to receive messages from the communication bus; and a transmitter configured to transmit first messages having a first message format and configured to transmit diagnosis messages having a second message format on the communication bus for use in determination of communication errors, wherein said transmitter is configured to send said one or more diagnosis messages having one or more of: (i) a predetermined pattern of symbols; (ii) a predetermined sending schedule; (iii) a predetermined line encoding method; (iv) a predetermined bit rate; (v) a predetermined position in one or more of the first messages; (vi) a predetermined signalling frequency that is out of a frequency band used for transmission of the first messages; and (vii) a predetermined signal strength different from the signal strength used to send the first messages.

Embodiments relate to including information in a data packet transmitted by a transmitting integrated circuit (e.g., SOC) to account for a time delay associated with an unsuccessful arbitration attempt to send the data packet over a multi-drop bus. The unsuccessful arbitration attempt by the integrated circuit may delay the transmission of the data packet until the multi-drop bus becomes available for the integrated circuit to send the data packet. The data packet includes a data field to include time delay information caused by the unsuccessful arbitration attempt. A receiving integrated circuit may determine the time that the data packet would have been sent out from the transmitting integrated circuit absent the unsuccessful arbitration attempt based on the delay information. Embodiments also relate to a synchronization generator circuit in an integrated circuit that generates timing signals indicating times at which periodic events occur at another integrated circuit.

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.

An exemplary method includes: obtaining, at one or more cloud servers, endpoint data of an endpoint computing device; based on the endpoint data, determining, by the one or more cloud servers, a plurality of script-language rules, wherein: each of the plurality of script-language rules corresponds to an atomic operation of detecting and/or removing at least one rootkit, the at least one rootkit comprises a target rootkit, and the plurality of script-language rules comprise a set of one or more rootkit rules corresponding to the target rootkit; and transmitting, by the one or more cloud servers to the endpoint computing device, the plurality of script-language rules, wherein the set of rootkit rules is executable at the endpoint computing device to detect and/or remove the target rootkit by, for each of the set of rootkit rules, executing a corresponding atomic operation.

A redundant system for processing at least one signal is described wherein the redundant system has N+1 devices include N operational devices and one reserve device. The N operational devices and the reserve device are interconnected with each other. The redundant system includes a system control integrated within one of the devices of the redundant system. The redundant system further includes switches that are associated with the operational devices. In case of a failure of a respective operational device, the system control is configured to cause at least one of the devices to operate the switch associated with the respective operational device having the failure. Further, a method of operating a redundant system for processing at least one signal is described.
