A communication system includes a first mobile terminal, a second mobile terminal, a smart device, and a router. The first mobile terminal, the second mobile terminal, and the smart device each establish a Wi-Fi link to a Wi-Fi router. The first mobile terminal is configured to manage the smart device. The router performs similarity comparison on first connection information and second connection information based on the first connection information generated when the first mobile terminal is connected to the router and the second connection information generated when the second mobile terminal is connected to the router, for example, a connection time point and connection duration. If a similarity reaches a first threshold, the router sends prompt information to the first mobile terminal. The prompt information is used to prompt whether to share management permission on the smart device with the second mobile terminal.

A client-side system can include a service proxy that can receive a request to perform a computing operation from a web application that is executable in a web browser of the client-side system. The service proxy can determine if the computing operation is executable by a local execution module that is external to the web browser and local to the client-side system. The local execution module may be different from the web application and may be configured to execute one or more computing operations using computing resources local to the client-side system. If the computing operation is executable by a local execution module, the service proxy can transmit a communication to the local execution module for causing the local execution module to execute the computing operation.

Some embodiments provide a local controller on a set of host computers that reduce the volume of data that is communicated between the server set and the set of host computers. The local controller executing on a particular host computer, in some embodiments, receives a portion of the namespace including only the policies (e.g., opcode) that are relevant to API-authorization processing for the applications executing on the particular host computer provided by a local agent executing on the computer to authorize the API requests based on policies and parameters. The local controller analyzes the received policies (e.g., policy opcodes) and identifies the parameters (e.g. operands), or parameter types, needed for API-authorization processing (e.g., evaluating the policy opcode upon receiving a particular API request) by the local agent. In some embodiments, the local controller performs this analysis for each updated set of policies (e.g., policy opcodes).

Examples described herein include systems and methods for multi-tenant event sourcing and audit logging in a cloud-based computing infrastructure. In an example method, an event package can be received from a first microservice of an application. The event can describe any action performed within the computing infrastructure and can include various types of information. For example, it can include an event type, event ID, object type, object ID, and parent event ID. The event package can be associated with a tenant and only provided to tenant-approved recipients. The recipient can use the event package to automatically carry out steps to recreate and configure an object, or to determine the source of an event or failure within the system.

A message transmitting and receiving method according to one aspect is performed by a communication apparatus, the communication apparatus including a middleware unit configured to manage a message published by a publisher in a publish/subscribe system in which a message is exchanged between the publisher and a subscriber via a broker, and a storage unit configured to store a library including functions configured to provide the broker, and includes the steps of performing, by the middleware unit, subscribing on the broker by setting a callback function, and upon receipt of a first message published by a device, passing, by the broker, the first message to the middleware unit by calling the callback function.

An apparatus and method for providing ML processing for one or more ML applications operating on one or more Internet of Things (IoT) devices includes receiving a ML request from an IoT device. The ML request can be generated by a ML application operating on the IoT device and include input data collected by the first ML application. A ML model to perform ML processing of the input data included in the ML request is identified and provided to an ML core for ML processing along with the input data included in the first ML request. The ML core produces ML processing output data based on ML processing by the ML core of input data included in the ML request using the ML model. The ML processing output data can be transmitted to the IoT device.

The disclosure provides a service request processing method. A service consumer transmits a service request, including a plurality of service producer types, and an access order of service producer instances corresponding to the plurality of service producer types is determined. The service producer instances corresponding to the plurality of service producer types are controlled to process the service request according to the access order.
