In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a cloud platform architecture in the prior art is shown; in an existing cloud platform (also called a cloud computing platform) architecture, a cloud platform is divided into a cloud area and an edge area, a center node is arranged in the cloud area, and the center comprises a plurality of servers. A plurality of edge nodes (e.g., edge node a, edge node B in fig. 1) are provided in the edge area, and one edge node includes a plurality of servers in which virtual devices for edge computation may be operated.
In the scenes of cloud games, cloud applications and the like, when a user is located in a first area, a terminal device is connected with an edge node A, the edge node A can call a service instance (such as an application program) in a virtual device and obtain corresponding service data, and after the terminal device is disconnected from the edge node A, the edge node A backs up the service data to a central node. When the user is in the second area, the edge node B is connected to the terminal device, and the edge node B needs to extract service data uploaded to the center node by the same user at other edge nodes from the center node, because the service data of the edge node needs to be acquired or uploaded to the center node through the center node, the requirement on the transmission bandwidth of the center node is high, and when the terminal device of the user is connected to the edge node different from the edge node connected last time, because the backup service data in the center node needs to be acquired, a certain delay exists, the time consumption for starting the application at the current edge node is high, and the efficiency of running the application at the edge node is low.

In practical application, the synchronization timing can be set according to actual requirements, for example: within the preset time after the terminal equipment is disconnected with the edge node. Taking the preset time after the terminal device is disconnected from the edge nodes as an example, the user is connected with one edge node through the terminal device in advance, and account information of the user logging in the terminal device can be obtained. And after the terminal equipment initiates a disconnection request (equipment release), determining the account information of the terminal equipment disconnected with the edge node as the account information to be synchronized.
based on the account information to be synchronized, determining node characteristic information of a plurality of edge nodes, wherein the node characteristic information is an index which is at least partially related to the account information to be synchronized and is used for evaluating the service data storage fitness of the edge nodes, namely the fitness of the edge nodes used for synchronizing the service data related to the account information to be synchronized can be evaluated through the node characteristic information, and then the edge nodes needing to be synchronized are screened out through the node characteristic information.
The edge node connected with the device terminal which logs in the account information to be synchronized last time can be determined, and the edge node is determined as the target edge node.
When the terminal equipment for logging in the account information to be synchronized is disconnected with the edge node, the edge node connected last stores the latest service data corresponding to the account information to be synchronized, so that the edge node connected last is determined as the target edge node.
the edge nodes needing to be synchronized can be determined according to the node characteristic information, and the synchronization information is generated based on the related information of the nodes needing to be synchronized.
The central node can send the synchronization information to the target edge node, and the target edge node can analyze the synchronization information to determine the edge node to be synchronized after receiving the synchronization information, and synchronize service data stored in the target edge node and corresponding to the information to be synchronized to the edge node to be synchronized, so that cross-node synchronization service data of the edge node is achieved.
In the embodiment of the application, a central node logs in account information to be synchronized of a terminal device by acquiring account information to be synchronized when an edge node is disconnected from the terminal device, then node characteristic information of a plurality of edge nodes is determined based on the account information to be synchronized, and in a target edge node among the plurality of edge nodes, the node characteristic information can be used for evaluating the degree of engagement of service data corresponding to the account information to be synchronized and synchronization of the plurality of edge nodes, and after the synchronization information is determined according to the node characteristic information, the synchronization information is sent to the target edge node; the target edge node is used for determining an edge node to be synchronized according to the synchronization information, synchronizing service data corresponding to the account information to be synchronized to the edge node to be synchronized, so that service data corresponding to a user can be stored in the edge node in a cloud platform comprising a center node and the edge node, and the service data is synchronized to other edge nodes without backing up the service data by the center node, thereby realizing the mobility of the service data between the edge nodes, ensuring that the user can always obtain the service data at a close position, improving the efficiency of service data synchronization, reducing the delay of starting a service instance in the edge node, and simultaneously greatly reducing the flow of the center node, reducing the bandwidth cost of data transmission of the center node, and solving the problems of high cost, high cost and high probability of service data synchronization from the center node in the prior art, High delay, etc.
Referring to fig. 3, a flow chart of steps of another embodiment of the data synchronization method of the present application is shown, applied to a central node, where the central node is connected to a plurality of edge nodes; the edge node is used for storing service data and is used for connecting with the terminal equipment.
The embodiment of the application can be applied to a cloud platform, the cloud platform can be provided with a central node and edge nodes, the central node is connected with a plurality of edge nodes, and the edge nodes connected with the central node can be controlled.
The embodiment of the application specifically comprises the following steps:
the account stock is the account number which is stored in the edge node in the service data corresponding to the account information and is active within a first preset time (for example, one month), and the first preset time can be set by a user. The account stock reflects how much active service data is stored by the edge node, and the higher the account stock is, the larger the number of users which may hit the node in the future is, and the less suitable the node is as a backup node (i.e. an edge node to be synchronized).
The computing resource inventory is the number of computing resources (including but not limited to one or two of computing resources and storage resources), and the higher the resource inventory is, the stronger the carrying capacity of the edge node is, the more suitable the edge node is as an edge node to be synchronized.
The historical online account level is the peak value of the online account number of the edge node at the same time when a second preset time (for example, one month) passes, and the second preset time can be set by a user. The higher the historical online account level is, the higher the probability of the future online account level is, and the less suitable the node is as the edge node to be synchronized.
The current online account water level is the current online user number of the edge node, and because the synchronization of the service data can increase the data processing pressure of the current node, the higher the current water level of the edge node is, the more unsuitable the edge node is to be used as the edge node to be synchronized.
The account information to be synchronized can include historical login positions, the position relevance is the relevance between the node position of the edge node and the historical login position, the relevance is highest when the node position and the historical login position are located in the same city, and the relevance is gradually decreased according to the city, province, large district and country. And the historical login position is the position of the last login terminal device of the account information to be synchronized.
The position of the terminal device for logging in the account information to be synchronized next time is at the same position as the historical login position with high probability, so that the closer the position of the edge node is to the historical login position, the more suitable the edge node is to be synchronized.
and the central node determines the edge node to be synchronized according to the account stock, the computing resource stock, the historical online account water level, the current online account water level and the position correlation degree.
In an alternative embodiment of the present application, step 303 comprises: generating scoring values of the edge nodes according to the node characteristic information; sequencing the edge nodes according to the grade values; and determining the edge nodes with the preset number in the sorted edge nodes as the edge nodes to be synchronized.
The score values of the edge nodes can be calculated according to the node characteristic information, and the edge nodes are sorted from large to small according to the score values. The higher the score value of the edge scoring node is, the more suitable the edge node is as the edge node to be synchronized. And determining the first few of the sequenced edge nodes as edge nodes to be synchronized.
In a specific application, a feature relationship may be determined for the node feature information, and the feature relationship is used for characterizing a relationship between the score value and the feature information.
The characteristic relationship may be calculated as follows:
p is the score value, C is the current online account level, H is the historical online account level, U is the account stock, S is the computing resource stock, and K is the position relevancy.
Calculating the score values P of the edge nodes through a formula (1), and sequencing the score values P from large to small, wherein the edge nodes corresponding to the first N score values in the sequencing are edge nodes to be synchronized.
In practical application, the central node may pre-process each edge node, and screen some edge nodes that are not suitable as edge nodes to be synchronized (for example, edge nodes in an abnormal state, edge nodes far away from a historical login position, and the like) first, so as to improve the efficiency of determining the edge nodes to be synchronized.
And 304, generating synchronous information aiming at the edge node to be synchronized.
Node identifiers can be set for the edge nodes, and synchronization information is generated based on the node identifiers of the edge nodes to be synchronized and account information to be synchronized.
The central node may send the synchronization information to the target edge node, and the target edge node may determine, using the synchronization information, an edge node to be synchronized and use service data corresponding to the account information to be synchronized as data to be synchronized, and synchronize the data to be synchronized to the edge node to be synchronized.
In an optional embodiment of the present application, the method further comprises: receiving a connection request sent by terminal equipment; the connection request comprises account information to be connected; determining distribution information of service data corresponding to the account information to be connected; determining edge nodes to be connected based on the distribution information of the service data; and controlling the edge node to be connected with the terminal equipment.
When a user logs in a mobile terminal and requests to connect an edge node, the central node may receive a connection request transmitted by the terminal device, where the connection request includes account information currently logged in the terminal device, that is, account information to be connected. The central node can determine the service data distribution condition, namely the distribution information, corresponding to the account information to be connected in each edge node, determine the edge node storing the service data corresponding to the account information to be connected as the edge node to be connected according to the distribution information, and control the edge node to be connected to the terminal device, so that the terminal device is forcibly dispatched to the edge node storing the service data corresponding to the account information for logging in the terminal device. Because the account information to be connected is synchronized to part of the edge nodes when the account information to be connected is disconnected from the edge nodes last time, if the edge nodes to be connected are the edge nodes of the service data synchronized last time, the service data does not need to be synchronized repeatedly after the current connection, and the efficiency of calling the edge nodes by a user is improved. If the edge node is not the edge node which synchronizes the service data last time, incremental synchronization can be performed on the edge node, so that time consumption of data synchronization when the terminal device is connected with the edge node is reduced, and high availability of the data is guaranteed.
In another optional embodiment of the present application, the method further comprises: receiving a connection request sent by terminal equipment; the connection request comprises a current login position; determining edge nodes to be connected based on the login position; controlling the edge node to be connected with the terminal equipment; and updating the service data of the edge node to be connected.
When a user logs in a mobile terminal and requests to connect edge nodes, a central node can receive a connection request transmitted by terminal equipment, the position of the terminal equipment, namely the current login position, is determined through the connection request, one edge node closest to the current login position is used as a node to be connected, and the edge nodes to be connected are controlled to be connected with the terminal equipment, so that when the terminal equipment is connected with the edge nodes, the edge nodes close to the edge nodes are ensured to be connected, and the communication efficiency between the edge nodes and the terminal equipment is improved. Because the account information to be connected is synchronized to partial edge nodes when the account information to be connected is disconnected with the edge nodes last time, if the edge nodes to be connected are the edge nodes of the service data synchronized last time, the service data does not need to be synchronized repeatedly after the current connection, the communication efficiency of the edge nodes and the terminal equipment is ensured, and the efficiency of calling the edge nodes by a user is improved. If the edge node is not the edge node which synchronizes the service data last time, incremental synchronization can be performed on the edge node, so that time consumption of data synchronization when the terminal device is connected with the edge node is reduced, and high availability of the data is guaranteed.
In the following, the present application is further described with an example, and with reference to fig. 4, a cloud platform architecture diagram provided in the present application is provided, where a central node and a plurality of edge nodes (for example, an edge node C, an edge node D, an edge node E, and an edge node F) are arranged in a cloud platform, the central node is provided with an equipment scheduling subsystem and a data dynamic scheduling subsystem, and the data dynamic scheduling subsystem is further provided with a dynamic balancing engine, a data synchronization policy component, and a data synchronization control component. An edge node runs a virtual appliance and a data synchronization edge component.
And when receiving a virtual device application request initiated by the terminal device, the device scheduling subsystem queries the data distribution condition of the user from the data dynamic scheduling system and performs device scheduling by taking the data distribution condition as one of the access parameters. And the method supports the strategies of forcibly scheduling to the nodes with data or selecting the nodes with the nearest positions to synchronize the data in real time, and the like.
When the device scheduling subsystem receives a virtual device release request initiated by the terminal device, the dynamic balancing engine of the data dynamic scheduling subsystem is controlled to acquire the synchronization strategies (redundancy quantity, synchronization strategies and the like) of service configuration from the data synchronization strategy center.
The control data dynamic scheduling subsystem calculates/stores node characteristic information such as resource historical water level, current water level, user stock, resource stock and the like according to the recent position change condition of a user, scores the edge nodes to obtain corresponding score values, selects proper nodes (for example, the edge nodes corresponding to the first N score values in the ranking are ranked from large to small according to a service configuration strategy (for example, the number of the nodes to be synchronized), generates synchronization information, and informs the data control component of the synchronization information and target edge node information.
And the data synchronization control component sends the synchronization information to the target edge node, so that the target edge carries out data synchronization across the edge nodes through the data synchronization edge component of the target edge. For example: and if the target edge node is the edge node A, and the edge nodes to be synchronized are the edge node D and the edge node E, the data synchronization component of the edge node A transmits the data to be synchronized to the edge node D and the edge node E.
Referring to fig. 5, a flowchart of steps of another embodiment of a data synchronization method according to the present application is shown, where the embodiment of the present application is applied to a target edge node, and the target edge node is determined by a central node among a plurality of edge nodes connected to the central node based on acquired information about an account to be synchronized; the method specifically comprises the following steps:
