Embodiment Construction

[0062] In order to make the above objects, features and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0063] refer to figure 1 , showing a cloud platform architecture in the prior art; in the existing cloud platform (also known as cloud computing platform) architecture, the cloud platform is divided into cloud and edge areas, and a central node is set in the cloud area, The hub contains multiple servers. There are multiple edge nodes in the edge region (eg figure 1 edge node A and edge node B), an edge node includes multiple servers, and virtual devices for edge computing can be run in the servers.

[0064] In scenarios such as cloud games and cloud applications, when a user is located in the first area, a terminal device is used to connect to edge node A, edge node A, and the terminal device can call a service instance (f...

Abstract

The embodiment of the invention provides a data synchronization method and device and a network system, the method is applied to a center node, and the center node is connected with a plurality of edge nodes; the edge node is used for storing service data and is used for being connected with terminal equipment; the method comprises the following steps: acquiring to-be-synchronized account information; the to-be-synchronized account information is account information logged in when the terminal equipment and the edge node are disconnected; determining node feature information of the plurality of edge nodes and a target edge node in the plurality of edge nodes based on the to-be-synchronized account information; determining synchronization information according to the node feature information; sending the synchronization information to the target edge node; and the target edge node is used for determining a to-be-synchronized edge node according to the synchronization information, and synchronizing the service data corresponding to the to-be-synchronized account information to the to-be-synchronized edge node. According to the embodiment of the invention, the service data can be synchronized to other edge nodes without backing up the service data through the center node.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a data synchronization method, a data synchronization device and a network system. Background technique [0002] With the development of 5G (5th Generation Mobile Communication Technology, fifth-generation mobile communication technology) and MEC (Mobile Edge Computing, multi-access edge computing), the edge cloud infrastructure has wide connectivity, low latency, large bandwidth capability. This promotes the upward movement of computing power and capabilities of terminal equipment to the edge cloud, and the lower terminal cost is accepted by users. [0003] Because user terminal equipment has the characteristics of high mobility and high change frequency, the conventional method of synchronizing user data to the central cloud has problems such as high cost and high delay. SUMMARY OF THE INVENTION [0004] In view of the above problems, the embodiments of the...
