A distributed service scheduling method, including obtaining, by a first terminal, an invocation request for a first service, determining whether the first terminal locally supports the first service, determining, by the first service, in response to the first terminal not locally supporting the first service, whether a local database comprises service information of the first service, determining, in response to the first terminal locally supporting the first service, identifier information of the first service and a second terminal that supports the first service, sending the identifier information of the first service and the invocation request to the second terminal, wherein the identifier information of the first service is used by the second terminal to match the first service, and receiving, by the first terminal, a result of executing the first service by the second terminal based on the invocation request.

Disclosed is a distributed computer system and a method of operation thereof. The distributed computer system includes a plurality of worker nodes. The collective learning of the worker nodes is managed within the distributed computer system. The operation of distributed computer system is coordinated by employing a distributed ledger arrangement. The distributed computer system comprises a monitoring arrangement to provide learning parameters to the worker nodes by way of executing smart contract. Each of the worker nodes is operable to train a computing model based on the learning parameters and a set of training data. The monitoring arrangement provides a reward to at least one of the worker nodes for training the computing model. The reward is determined based on a number and frequency of intermediary computing models provided by a given worker node to a remainder of the worker nodes; and a quality of the intermediary computing models.

The present disclosure discloses a method for preheating a resource file, and a central management system, and relates to the field of network communication technology. The method includes: according to historical bandwidth data of a target intermediate node, determining a bandwidth off-peak period of the target intermediate node; during the bandwidth off-peak period of the target intermediate node, pre-caching the resource file on an edge node corresponding to the target intermediate node.

A logical grouping of subgroups of server clusters forms a failover super-cluster. A logical grouping of groups of servers provides high availability by, upon failure of an entire group (site), failing over an entire subgroup to a different subgroup. Yet within each subgroup local failovers continue to maintain application high availability during instances in which the site remains operational.

A system for acquisition and storage of data relative to BACnet objects of a BACnet standard HVAC system having BACnet network, where BACnet objects each generate change data upon occurrence of a change in a value thereof and a controller receives and concatenates the change data of the plurality of BACnet objects into payloads encapsulated into system specific data packets conforming to the BACnet data packet standards and transmitted over the BACnet network. The system also has a data conversion unit receiving the system specific data packets, retrieving the change data therefrom and generating database write commands including the change data. The system also comprises a main data acquisition database in data communication with the data conversion unit and receiving the database write commands therefrom. The main data acquisition database stores the data relative to all data changes of the standard BACnet objects over time.

In order to use zero trust network resources distributed across multiple gateways, an agent is deployed on an endpoint of an enterprise network. The agent maps requests for specific applications to corresponding gateways. The agent may also multiplex or otherwise aggregate communications among different network applications and gateways in order to provide seamless, transparent access to the distributed resources at a single endpoint, and/or within a single interface.

A system and method of operating a content distribution system includes determining a placement metric for a first object, communicating the first object to a local cloud associated with a user device or a network cloud based on the placement metric by control of a content distribution system, storing the first object in the local cloud or the network cloud and consuming the first object using the local cloud or the network cloud.

A virtual environment (e.g., a virtual desktop or virtual application) may be configured to provide an option to share data that exists within the virtual environment. Upon selecting the option, a device that implements the virtual environment (e.g., a virtualization server) may send a sharing command to a client device that is accessing the virtual environment. The client device may receive the sharing command and detect one or more sharing mechanisms available via the client device (e.g., installed applications with a functionality for sharing data). The client device may then provide a list of sharing mechanisms to a user and receive a user selection of a sharing mechanism. The client device may then share the data with another device using the sharing mechanism selected by the user.
