Methods of synchronizing sequence numbers of a number of devices of a network are disclosed. A method may include incrementing, at each of a first device and a second device of a network, a sequence number, wherein the sequence number is indicative of a number of frames generated at the associated device since the timing event. The method may also include inserting, at each of the first device and the second device, the sequence number into an associated frame. Related networks and devices are also disclosed.

A system may include a central computational instance configured to provide a service to a plurality of computational instances, wherein the service is associated with configurations respectively corresponding to the computational instances. The system may also include a computational instance dedicated to a managed network and storing a synchronization history specifying information that was synchronized between the computational instance and the central computational instance. One or more processors may be configured to: (i) receive a configuration of the service into the computational instance, wherein the configuration was received from a non-production computational instance of the plurality of computational instances; (ii) read, from the configuration, a synchronization identifier; (iii) determine that the synchronization identifier does not exist in the synchronization history; and (iv) in response to determining that the synchronization identifier does not exist in the synchronization history, transmit the configuration to the service provided by the central computational instance.

Example implementations relate to data synchronization. According to an example, a system includes a processing system to execute a workload container, the workload container including a user workload application, the user workload application including a sync client; a data storage system, coupled to the processing system, to store user data; and a sync controller to control synchronization of the user data between the sync client and a sync server executing on a customer computing system and pull a selected portion of the user data from the customer computing system to the sync client. The sync client incrementally updates the user data stored on the data storage system with the selected portion of the user data to synchronize the user data between the customer computing system and the cloud computing system.

In some embodiments, a first replica sends a message to second replicas for pre-processing of an operation. The first replica receives pre-processing results from the second replicas. A pre-processing result is generated by pre-processing the operation using a first state. The first replica analyzes the pre-processing results to determine whether an agreement on a validated pre-processing result is received. When it is determined the agreement on the validated pre-processing result is received, the first replica performs a consensus protocol stage with the second replicas to order the request in an order of execution of requests that defines when to execute the request with respect to another request at the second replicas. Information for the validated pre-processing result is provided to the set of second replicas to determine whether contention results between the first state and a second state that is based on the order of execution of requests.

In an embodiment, a flick motion is detected on a touch screen interface of a first device. In response to detecting the flick motion: data associated with the flick motion is identified and transmitted to a second device. The data may be automatically displayed in response to detecting the flick motion.

An algorithm download method, a device, and a related product. The method includes: obtaining an algorithm identifier of an algorithm and a capability description of a client; sending the algorithm identifier and the capability description to a cloud; and receiving a version code that is of the algorithm and that is returned by the cloud, where the version code is obtained by the cloud by searching based on the algorithm identifier and the capability description. According to the foregoing solution, an algorithm can be easily downloaded.

There are provided systems and methods for a network cache of device input for redundancy during device inoperability. A device may detect that the device is in danger of failure, for example, if a battery is low on the device, the device is damaged, or the device may lose network connectivity. On detection of such a condition, the device may request that a server that performs electronic transaction processing establish or trigger a mode that allows for caching of transaction data as input for the transaction data is entered to a device, which may be done by sending signaling to the server indicating the condition that affects the device's operability. The server may then cache input for the transaction data. If the device fails prior to approving and completing electronic transaction processing, the server may use the cached data to generate a digital ledger for another entity.
