[0039] Cloud technology refers to a hosting technology that unifies hardware, software, network and other resources within a wide area network or local area network to achieve data computing, storage, processing and sharing.

[0040] Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on the cloud computing business model. It can form a resource pool and be used on demand, which is flexible and convenient. Cloud computing is an important support for cloud technology. The backend system of cloud computing technology requires a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the rapid development and application of the Internet industry, in the future, each item may have its own identification mark, which needs to be transmitted to the backend system for logical processing. Data of different levels will be processed separately. All kinds of industry data need strong system backing support, which can only be achieved through cloud computing.

[0041] Cloud gaming, also known as gaming on demand, is an online gaming technology based on cloud computing technology. Cloud gaming technology enables thin clients with relatively limited graphics processing and data computing capabilities to run high-quality games. In a cloud gaming scenario, the game client does not run on the user's device, but on a cloud server, which renders the game scene into a video and audio stream and transmits it to the user's device over the network. The user device does not need to have powerful graphics computing and data processing capabilities, but only needs to have basic streaming media playback capabilities and the ability to obtain player input commands and send them to the cloud server.

[0042] Specifically, in Figure 1 In the application scenario shown, the game server is used to store game player account information and game backend services, etc., and is used to interact with the rendering server. The game resource server is used to store game resource data, such as game image information, game video information, etc. The rendering server is the aforementioned cloud server. The game client runs in the rendering server. The rendering server renders the game scene into an audio and video stream, and then transmits it to the user device through the network. The user device displays these audio and video streams and sends the user's operation instructions to the rendering server through the control stream to realize the control of the game character.

[0043] Figure 1 Each server shown can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The user device can be a smart phone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, etc., but is not limited to this. The user device and the rendering server can be directly or indirectly connected via wired or wireless communication, and this application is not limited here.

[0044] The cloud game update solution proposed in the related art usually uses a server as a source machine on the service side to monitor whether the game client has updates. When it is detected that the game client needs to be updated, the source machine sends the game update package to each game client. During this period, the cloud game is in a service suspension stage and can only be opened after all clients are updated. However, the update time of this update solution is relatively long, and it cannot ensure the "click-to-play" of cloud games, which affects the experience of game players. Based on this, an embodiment of the present application proposes a data synchronization solution that can be applied to cloud game updates, which can effectively improve the efficiency of data synchronization, thereby shortening the duration of cloud game updates, reducing the time for game players to wait for the server to be opened, and is conducive to improving the experience of game players. The following is a detailed description of the technical solution of the embodiment of the present application:

[0045] like Figure 2 As shown, in an exemplary system architecture of an embodiment of the present application, a task distributor 201, a task management component 202 and a node set 203 may be included. Among them, the node set 203 includes multiple nodes, which are nodes for data synchronization. In the cloud game scenario, for example, they may be nodes run by the cloud game client, that is, rendering server nodes. The task distributor 201 and the task management component 202 may run in the same physical entity or in different physical entities, for example, they may be implemented through different servers.

[0046] When the task distributor 201 detects that data needs to be updated, such as the cloud game client needs to be updated, it can generate task allocation information, which contains information about the data providing node and the data receiving node. The data providing node is a node that already contains the target data that needs to be synchronized (such as the update package of the game client, etc.), and the data receiving node is a node that needs to synchronize the target data. For example, node 2031 already contains the target data that needs to be synchronized, and node 2032 and other nodes are nodes that need to synchronize the target data, then node 2031 is a data providing node, and node 2032 and other nodes are data receiving nodes.

[0047] After generating the task assignment information, the task distributor 201 can send the task assignment information to the task management component 202. The task management component 202 will generate a data synchronization task based on the task assignment information. The data synchronization task is used to instruct the specified data receiving node to synchronize the target data from the specified data providing node, such as instructing node 2032 and other nodes to synchronize the target data from node 2031.

[0048] After generating the data synchronization task, the task management component 202 may send the data synchronization task to at least the designated data receiving node to instruct the designated data receiving node to synchronize the target data from the designated data providing node. Of course, the task management component 202 may also send the data synchronization task to the designated data providing node to instruct the designated data providing node to provide the target data to be synchronized to the designated data receiving node.

[0049] After the task management component 202 obtains the execution result of the data synchronization task, if the execution result indicates that the designated data receiving node has successfully synchronized the target data, the task management component 202 can return update information to the task distributor 201 to indicate that the designated data receiving node is changed to a data providing node. For example, if node 2032 successfully synchronizes the target data, then node 2032 can be changed to a data providing node.

[0050] If the task distributor 201 determines that there are still data receiving nodes, the task allocation information can be generated again. When the task allocation information is generated again, since the number of data providing nodes is increased, the target data can be synchronized to the data receiving nodes through a larger number of data providing nodes, thereby effectively improving the efficiency of data synchronization and greatly shortening the duration of data synchronization.

[0051] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0052] Figure 3A flow chart of a data synchronization method according to an embodiment of the present application is shown. The data synchronization method may be performed by Figure 2 The task management component 202 shown in FIG. 1 is executed, and the task management component 202 can be run in the server in the form of a service. Figure 3 As shown, the data synchronization method at least includes steps S310 to S340, which are described in detail as follows:

[0053] In step S310, task assignment information sent by the task distributor is received, and the task assignment information includes information of a data providing node and information of a data receiving node. Optionally, the data providing node and the data receiving node may be used for updating the cloud game.

[0054] In one embodiment of the present application, the data providing node is a node that already contains the target data that needs to be synchronized (such as an update package of a game client, etc.), and the data receiving node is a node that needs to synchronize the target data. In an embodiment of the present application, after the data receiving node has synchronized the target data, the role of the data receiving node is changed to a data providing node. Optionally, the information of the data providing node can be identification information, network address, etc. of the data providing node. Similarly, the information of the data receiving node can be identification information, network address, etc. of the data receiving node.

[0055] In one embodiment of the present application, if the target data to be synchronized is cloud game update data, the data providing node and the data receiving node may be a cloud game rendering server node. After the cloud game rendering server node completes the synchronization of the cloud game update data, cloud game services may be provided.

[0056] Optionally, the information of the data providing node and the information of the data receiving node contained in the task assignment information may be for the same area. For example, if nodes in multiple areas need to synchronize data, then the nodes in each area can perform data synchronization processing separately according to the data synchronization scheme of the embodiment of the present application.

[0057] In step S320, a data synchronization task is generated according to the task allocation information, where the data synchronization task is used to instruct the designated data receiving node to synchronize target data from the designated data providing node.

[0058] In one embodiment of the present application, the process of generating a data synchronization task according to the task allocation information may be to parse the task allocation information, obtain the information of the data providing node and the information of the data receiving node, and then generate the data synchronization task according to the information of the data providing node and the information of the data receiving node, and a preconfigured task template. For example, the data synchronization task may be generated by filling the information of the data providing node and the information of the data receiving node into the task template.

[0059] Optionally, the preconfigured task template may include task type information. Then, when generating a data synchronization task, the task type information in the task template may be set as the data synchronization type. Then, the data synchronization task is generated based on the information of the specified data receiving node and the information of the specified data providing node.

[0060] It should be noted that if the task allocation information already includes which data providing nodes provide target data to which data receiving nodes, then when generating the task allocation information, the task allocation information can be directly generated based on this information. If the task allocation information only includes the information of the data providing nodes and the data receiving nodes, and does not specify which data providing nodes provide target data to which data receiving nodes, then the task management component can make allocations based on the information of the data providing nodes and the data receiving nodes. For example, allocations can be made based on the distance and communication status between the data providing nodes and the data receiving nodes to ensure the efficiency of data synchronization.

[0061] In step S330, the data synchronization task is sent to at least a designated data receiving node, and the execution result of the data synchronization task is obtained.

[0062] In this step, the data synchronization task is at least sent to the designated data receiving node, which can instruct the designated data receiving node to synchronize the target data from the designated data providing node. Of course, the task management component can also send the data synchronization task to the designated data providing node to instruct the designated data providing node to provide the target data to be synchronized to the designated data receiving node.

[0063] Optionally, in one embodiment of the present application, the task management component can send the data synchronization task to the task publish-subscribe platform, and then the designated data receiving node (and the designated data providing node) can obtain the data synchronization task by monitoring the task publish-subscribe platform. The task publish-subscribe platform can be a Kafka platform, which is a high-throughput distributed publish-subscribe messaging system that can process all action flow data of consumers on the website.

[0064] In one embodiment of the present application, the task management component can also obtain the status information of the data providing node and the status information of the data receiving node from the task publishing and subscription platform, and the status information is used to indicate whether it is in an online state, and then the task management component can return the status information of the data providing node and the status information of the data receiving node to the task distributor. Specifically, the data providing node and the data receiving node can autonomously report the heartbeat status to the task publishing and subscription platform, and then the task management component can determine whether the node is in an online state according to the reporting time of the heartbeat status. For example, if the time of the heartbeat status reported by a node is too long from the current time, then it can be determined that the node is offline.

[0065] Continue to refer to Figure 3 As shown, in step S340, if the execution result indicates that the designated data receiving node has successfully synchronized the target data, update information is returned to the task distributor, and the update information is used to indicate that the designated data receiving node is changed to a data providing node, so that the task distributor sends the task allocation information again according to the updated information.

[0066] Specifically, after receiving the update information, the task distributor can determine whether there are still data receiving nodes. If there are still data receiving nodes, the task allocation information can be generated again. When the task allocation information is generated again, since the number of data providing nodes has increased, the target data can be synchronized to the data receiving node through a larger number of data providing nodes, thereby effectively improving the efficiency of data synchronization and greatly shortening the duration of data synchronization.

[0067] In one embodiment of the present application, in addition to sending data synchronization tasks to the task publishing and subscription platform, the task management component can also generate other tasks to be executed, and the tasks to be executed include at least one of the following: task type information, task trigger condition information, task execution target information, and task execution status information. Then the task management component can send the generated tasks to be executed to the task publishing and subscription platform, so that the designated nodes among the data providing nodes and the data receiving nodes can obtain the tasks to be executed by monitoring the task publishing and subscription platform for processing.

[0068] Optionally, task type information may be, for example, a data modification task, a data deletion task, a data sending task, etc.; task trigger condition information is used to indicate under what conditions the task is triggered, such as being triggered after executing a set operation, etc.; task execution target information is used to indicate the goal expected to be achieved by executing the task; task execution status information is used to indicate the execution status of the task, such as not executed, executed, failed, etc.

[0069] In one embodiment of the present application, if the task management component detects that the number of nodes that have completed data synchronization has reached a set number, the target node that has completed data synchronization can be called to perform a simulated operation based on the synchronized data, and then the interface of the target node during the simulated operation is captured, and the interface is compared with the set interface. If the interface matches the set interface, a business access service is provided based on the node that has completed data synchronization. The technical solution of this embodiment can realize automatic testing after data synchronization, and can provide business access services to the outside without waiting for all nodes to complete synchronization, thereby reducing the waiting time for services.

[0070] For example, for cloud gaming, when more than half of the rendering servers in a certain area have completed the update of the cloud gaming client, these rendering servers can be called to simulate the operation of the cloud gaming client and capture the interface during the simulation process (such as the cloud gaming node, which can be the interface for entering the game). When the interface matches the set interface, cloud gaming services can be provided through these rendering servers. There is no need to wait for all rendering servers to complete the update before opening the service, which reduces the waiting time for cloud gaming.

[0071] Figure 4 A flow chart of a data synchronization method according to an embodiment of the present application is shown. The data synchronization method may be performed by Figure 2 The task distributor 201 shown in FIG. 1 is executed, and the task distributor 201 can be run in the server in the form of a service. Figure 4 As shown, the data synchronization method at least includes steps S410 to S440, which are described in detail as follows:

[0072] In step S410, task allocation information is generated, and the task allocation information includes information of a data providing node and information of a data receiving node. Optionally, the data providing node and the data receiving node may be used for updating a cloud game.

[0073] In one embodiment of the present application, task allocation information can be generated when an update of a data source is detected. Alternatively, task allocation information can be generated when a set update time is reached. That is, the task distributor can trigger a task allocation operation by detecting whether a data source is updated, or can trigger a task allocation operation at a set time. For example, if it is determined that the cloud gaming client will be updated at a certain point in time based on information obtained in advance, then the task allocation operation can be triggered at that point in time.

[0074] In one embodiment of the present application, the data providing node is a node that already contains the target data that needs to be synchronized (such as an update package of a game client, etc.), and the data receiving node is a node that needs to synchronize the target data. In an embodiment of the present application, after the data receiving node has synchronized the target data, the role of the data receiving node is changed to a data providing node. Optionally, the information of the data providing node can be identification information, network address, etc. of the data providing node. Similarly, the information of the data receiving node can be identification information, network address, etc. of the data receiving node.

[0075] In step S420, the task allocation information is sent to the task management component, so that the task management component generates a data synchronization task according to the task allocation information and sends it to the designated data receiving node, wherein the data synchronization task is used to instruct the designated data receiving node to synchronize target data from the designated data providing node.

[0076] Optionally, the process in which the task management component generates a data synchronization task according to the task allocation information and sends it to a designated data receiving node can refer to the technical solution of the aforementioned embodiment and will not be described in detail.

[0077] In step S430, update information returned by the task management component is received, where the update information is used to indicate that the designated data receiving node is changed to a data providing node.

[0078] In one embodiment of the present application, after receiving the execution result of the data synchronization task, the task management component can determine whether the designated data receiving node has successfully synchronized the target data based on the execution result, and if the synchronization is successful, return update information to the task distributor.

[0079] In step S440, after the designated data receiving node is changed to a data providing node, if there are still data receiving nodes, task allocation information is generated again.

[0080] Specifically, after receiving the update information, the task distributor can determine whether there are still data receiving nodes. If there are still data receiving nodes, the task assignment information can be generated again. When the task assignment information is generated again, since the number of data providing nodes has increased, it is possible to synchronize target data to the data receiving nodes through a larger number of data providing nodes, thereby effectively improving the efficiency of data synchronization, such as improving the update efficiency of cloud games and greatly shortening the time for data synchronization.

[0081] In one embodiment of the present application, the task distributor can obtain the information of the data providing node and the information of the data receiving node from a designated database, wherein the designated database includes a first list and a second list, wherein the first list is used to store the information of the data providing node and the second list is used to store the information of the data receiving node, and then the designated data receiving node is changed to a data providing node by moving the information of the designated data receiving node in the second list to the first list. The designated database can be a Redis database, a MySQL database, etc.

[0082] The above respectively describes the implementation details of the technical solution of the embodiment of the present application from the perspectives of the task management component and the task distributor. The following describes the technical solution of the embodiment of the present application in detail based on the application scenario of cloud gaming:

[0083] like Figure 5 As shown, according to an embodiment of the present application, the update process of the cloud game includes the following steps:

[0084] Step S501, obtaining a cloud game maintenance announcement. Optionally, the cloud game maintenance announcement may be cloud game update information or cloud game maintenance information released by the game operation and maintenance party, which includes time information for cloud game update or maintenance.

[0085] Step S502, set scheduled maintenance. Optionally, the time of scheduled maintenance can be set according to the update or maintenance time information included in the cloud game maintenance announcement.

[0086] Step S503: The project team pushes game updates. Optionally, the project team may be the game operation and maintenance party, and the project team pushes game updates, that is, releases game update packages or game maintenance data.

[0087] Step S504, triggering source machine update. Optionally, the source machine may be the first server selected to receive the game update package, for example, each region is provided with a source machine, and the source machine in each region is used to receive the game update package or game maintenance data for upgrading the server in the region.

[0088] Step S505, distributing files. Optionally, the distributed files are synchronized game update packages or game maintenance data. When distributing files, the data synchronization solution in the aforementioned embodiment of the present application can be used to improve the efficiency of data synchronization and shorten the duration of cloud game updates.

[0089] Step S506, game automation test. Optionally, the game automation test can also adopt the test scheme in the aforementioned embodiment of the present application, that is, to capture the operation interface by simulating operation, and to determine whether the update is successful by comparing the operation interface with the setting interface.

[0090] Step S507, game server launch. Optionally, for cloud gaming, if more than half of the rendering servers in a certain region have completed the update and passed the test, cloud gaming services can be provided through these rendering servers, without waiting for all rendering servers to complete the update before launching the server, thus reducing the waiting time for cloud gaming.

[0091] Figure 6 A schematic diagram of a cloud game update according to an embodiment of the present application is shown. Specifically, cloud games can be deployed in multiple areas (such as area 1, area 2, ..., area n, etc.), and each area can be provided with a distribution source machine, which is used to obtain game update packages. In each area, the stream host adapter is used to monitor whether the cloud game client needs to be updated. If an update is required, the stream host (i.e., the distribution source machine) is called to obtain the game update package, and a self-update operation is performed, and then the service 601 of initializing the allocation of resources is triggered.

[0092] In the service 601 for initializing resource allocation, by updating the platform game configuration, the business architecture can be the deployment architecture of the server (such as the rendering server of the cloud game), such as which operators' servers are deployed to support, and the deployment location and number of these servers. The initialization resource list contains the files that need to be updated, as well as the server list information that needs to be updated. Writing the allocation status to Redis is to write the role of the server to Redis. For example, when the server has not been updated, the role of the server can be the synchronized end (that is, it needs to obtain game update packages from other servers). If the server has been updated, the role of the server can be set to the synchronized end (that is, it can provide game update packages to other servers).

[0093] The service 601 for initializing resource allocation can send the task relationship between the syncing end and the synced end (such as which synced ends obtain game update packages from which syncing ends) to TaskFlow (which can exist in the form of a service) to perform task triggering operations. TaskFlow can parse the task relationship, generate data synchronization tasks, and distribute them to TaskWorkers running in the rendering servers in each region, and then the TaskWorkers in each rendering server can perform synchronization operations on the game update packages according to the data synchronization tasks.

[0094] When TaskWorker completes the data synchronization task, it can report the result to TaskFlow. TaskFlow can call back the result, adjust the update progress, and change the task status, that is, convert the role of the rendering server that has completed the update into a synchronization end (that is, it can provide game update packages to other servers), and then write it to Redis.

[0095] Redis may include a list of synchronization terminals and a list of synchronization terminals. If the list of the synchronization terminal still includes information of rendering servers, it means that some rendering servers have not completed the update operation. At this time, the service 601 for initializing resource allocation may trigger the next round of synchronization tasks until the list of the synchronization terminal no longer includes rendering servers.

[0096] At the same time, when a certain number of rendering servers that have completed synchronization in a certain area reaches a certain number (such as more than half), TaskFlow can call the game's automated test. When the test results show that the test is correct, the server can be automatically put online to provide services to game players without having to wait for all rendering servers to complete synchronization. When performing automated testing, the game screen can be captured through simulated operation, and image recognition can be used to determine whether the game is launched normally (such as whether the captured game screen is consistent with the expected screen). After the test is correct, the server is automatically opened. No manual intervention is required in the entire process, truly realizing automation.

[0097] Optionally, the service 601 for initializing resource allocation and TaskFlow may be set in the same physical entity (such as a server) or in different physical entities.

[0098] In one embodiment of the present application, Figure 7 As shown, the task dispatching between TaskFlow and TaskWorker can be achieved through the intermediate component Kafka. Specifically, the operation and maintenance personnel can create a task template on the Taskflow side, in which they can select the task type, set the trigger information, set the task execution target information, and write the status. Optionally, the task type information can be, for example, a data modification task, a data deletion task, a data sending task, etc.; the trigger information can be the task trigger condition information, which is used to indicate the conditions under which the task is triggered, such as triggering after executing the set operation, etc.; the task execution target information is used to indicate the goal expected to be achieved by executing the task; the status writing is used to indicate the execution status of the task, such as not executed, executed, failed to execute, etc.

[0099] For data synchronization tasks, TaskFlow pushes the task to the kafka queue after generating the game update task. Taskworker monitors the task message in the kafka queue in real time. If there is any, it consumes the task, that is, parses the actual execution command and runs it in the rendering server. When the rendering server completes the command, the execution result message is sent back to TaskFlow through the task callback, and TaskFlow rewrites the task status to completed.

[0100] At the same time, the Taskworker can report the heartbeat status autonomously. TaskFlow determines whether the rendering server is offline based on the reporting time. If it is offline, the problematic rendering server will be skipped when issuing tasks.

[0101] The game update solution of the embodiment of the present application can improve the update efficiency of cloud games and greatly shorten the update time of cloud games. Of course, the data synchronization solution of the embodiment of the present application can also be applied to other data synchronization application scenarios.
