[0049] The embodiments of the present application provide a service docking method, device, electronic device and storage medium. The method provided by the embodiments of the present invention can be applied to any required electronic device, for example, it can be a server, terminal and other electronic devices, which are not specifically limited here. For the convenience of description, it is referred to as electronic device in the following.

[0050] According to one aspect of the embodiments of the present application, a method embodiment of a service docking method is provided. Figure 1 A flow chart of a service connection method provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0051] Step S11: monitoring service demand information from the second service node, wherein the service demand information carries at least one target function item currently required by the second service node.

[0052] The method provided in the embodiment of the present application is applied to the first service node of the service node cluster, and the first service node can be any service node in the service node cluster. The service node can be an intelligent device, and a service set is deployed on the intelligent device. The service set includes services applicable to multiple functional items. A service can be composed of one or more algorithms, such as: image recognition service (detection algorithm, classification algorithm), data governance service, data security service, etc.

[0053] In an embodiment of the present application, the first service node can monitor the service request sent by the second service node in real time. The second service node can be any other service node in the service node cluster except the first service node, or a service node outside the service node cluster. After receiving the service request, the first service node will parse the service request and obtain the service demand information carried by the service request. The service request information includes at least one target function item, and the target function item includes an image detection function, a data governance function, and the like.

[0054] Step S12: Obtain a service set currently deployed by the first service node, where the service set includes multiple services.

[0055] In the embodiment of the present application, after obtaining the target function item, the first service node will first call its currently deployed service set. The services in the service set may be composed of one or more algorithms. The service set may be pre-deployed on the service node by the developer, or may be learned by the service node and other service nodes in the service node cluster. For example, each service node in the service node cluster can periodically learn from each other, obtain services that it has not deployed from other service nodes, and synchronously update the service to its own service set.

[0056] Step S13: Detect whether there is a target service matching the target function item in the service set, and obtain a detection result.

[0057] In the embodiment of the present application, detecting whether there is a target service matching the target function item in the service set and obtaining a detection result includes the following steps A1-A3:

[0058] Step A1, obtaining the function item corresponding to each service in the service set.

[0059] Step A2: Calculate the similarity between the function item and the target function item, and determine the service corresponding to the function item with a similarity greater than a preset similarity as a candidate service.

[0060] Step A3: determine the service performance parameters corresponding to the candidate services, determine the candidate service with the highest service performance parameters as the target service, and determine the detection result based on the target service.

[0061] In the embodiment of the present application, each service in the service set corresponds to a function item, so the first feature vector of the function item is extracted, and the second feature vector of the target function is extracted, the similarity between the function item and the target function item is calculated based on the first feature vector and the second feature vector, and the service corresponding to the function item with a similarity greater than the preset similarity is determined as a candidate service. Then the service performance parameters corresponding to each candidate service are detected, and the service performance parameters can be the service efficiency, service times, etc. of the candidate service. At the same time, the weights corresponding to each service performance parameter are determined, such as the weight corresponding to the service efficiency, the weight corresponding to the service times, and the scores are calculated using each service performance parameter and the corresponding weights, and the target service with the highest score is determined. Finally, the detection result is determined based on the target service, and the process of determining the detection result includes: when the score corresponding to the target service is less than the preset score, it is determined that the target service is invalid (that is, the detection result is that the target service does not exist). If the score corresponding to the target service is greater than or equal to the preset score, it is determined that the target service is valid (that is, the detection result is that the target service exists).

[0062] Step S14, determining a service docking process corresponding to the detection result, and docking the first service node with the second service node according to the service docking process, so as to deploy the target service to the second service node.

[0063] In the embodiment of the present application, the first service node is connected to the second service node according to the service connection process to deploy the target service to the second service node, including the following steps B1-B2:

[0064] Step B1: When the detection result shows that the target service exists in the service set, a first transmission link is established between the first service node and the second service node.

[0065] Step B2: deploy the target service to the second service node based on the first transmission link.

[0066] In an embodiment of the present application, when the detection result shows that the target service exists in the service set, the first service node directly establishes a first transmission link with the second service node, and deploys the target service to the second service node based on the first transmission link.

[0067] In the embodiment of the present application, the first service node is connected to the second service node according to the service connection process to deploy the target service to the second service node, including the following steps B1-B4:

[0068] Step B1: When the detection result shows that the target service does not exist in the service set, a service request carrying the target function item is sent to the service node cluster where the first service node is located, and the service request is used to obtain the target service corresponding to the target function item.

[0069] Step B2, receiving request response information from the third service node in the service node cluster, obtaining the target service from the third service node based on the request response information, and deploying the target service, the third service node is any service node in the service node cluster.

[0070] Step B3: Establish a first transmission link between the first service node and the second service node.

[0071] Step B4: deploy the target service to the second service node based on the first transmission link.

[0072] In an embodiment of the present application, when the detection result is that the target service does not exist in the service set, the first service node will broadcast a service request carrying the target function item in the service node cluster. When the third service node in the service node cluster monitors the service request, the third service node can be any service node in the service node cluster except the first service node. The third service node will query whether there is a target service that meets the target function item from the service set of its identity. If so, the third service node will respond to the service request and feedback the request response information to the first service node. The request response information carries the target service. After receiving the request response information, the first service node establishes a first transmission link between the first service node and the second service node, and deploys the target service to the second service node based on the first transmission link.

[0073] In an embodiment of the present application, establishing a first transmission link between a first service node and a second service node includes: sending a docking request to the second service node, wherein the docking request carries the first identity information of the first service node, for example, the identity information mainly includes identity credentials, node registration information, etc. Receiving docking response information fed back by the second service node based on the docking request, wherein the docking response information carries the second node identity information of the second service node, and the second identity information is sent by the second service node after the first identity information is authenticated. Authenticate the second node identity information, and if the second node identity information is authenticated, establish the first transmission link between the first service node and the second service node.

[0074] In the embodiment of the present application, the method further includes the following steps C1-D3:

[0075] Step C1: if no request response information from the third service node is received within a preset time, generate broadcast information based on the function item and send the broadcast information.

[0076] Step C2: receiving broadcast response information fed back by the fourth service node based on the broadcast information, wherein the broadcast response information carries an identifier that the fourth service node has deployed the target service.

[0077] Step C3: forward the broadcast response information to the second service node, so that the second service node establishes a second transmission link with the fourth service node based on the broadcast response information, and obtains the target service based on the second transmission link.

[0078] In an embodiment of the present application, when all service nodes in the service node cluster do not have a target service that meets the target function item, the first service node generates a broadcast message based on the target function item and sends the broadcast message. At this time, the first service node mainly sends the broadcast message outside the service node cluster. When the fourth service node outside the service node cluster receives the broadcast message, it will detect whether it carries the target service that meets the target function item. If there is, it wants to feedback the broadcast response information to the first service node. When the first service node receives the broadcast response information from the fourth service node outside the service node cluster based on the broadcast information feedback, the broadcast response information is forwarded to the second service node, so that the second service node establishes a second transmission link with the fourth service node based on the broadcast response information, and obtains the target service based on the second transmission link.

[0079] This application can automatically query the target service that matches the demand item according to the service demand, and select the corresponding service docking method based on the final query result. It realizes automatic service docking when the self-deployed service cannot meet the demand, and improves service efficiency.

[0080] In an embodiment of the present application, the method further includes: sending a service update request to the service node cluster where the first service node is located, receiving at least one newly added service fed back by each service node in the service node cluster based on the service update request, and updating the service set based on the newly added service.
