[0052] It should be noted that in the embodiments of the present application, when the policy management module loads the initial policy instance to the target network domain through the network management module, the policy management module can load the initial policy instance to the specified network domain and administrative region through the network management module.

[0053] Further, in the embodiments of the present application, the policy management module can bind the target policy instance corresponding to the initial policy instance with the corresponding target service object, to determine the correspondence between the target policy instance and the target service object; wherein the target policy instance includes the target trigger event corresponding to the initial trigger event.

[0054] It should be noted that in the embodiments of the present application, when the policy management module determines the target policy instance corresponding to the initial policy instance, the policy management module can load the initial policy instance from the first management device to the second management device, that is, the initial policy instance can be decomposed from the first management device to the second management device, to obtain the target policy instance corresponding to the initial policy instance.

[0055] It should be noted that in the embodiments of the present application, the first management device can be a cross-domain management device, and the type of the first management device is not limited in the present application.

[0056] It should be noted that in the embodiments of the present application, the second management device can be a sub-domain management device, and the type of the second management device is not limited in the present application.

[0057] Further, in the embodiment of the present application, the policy execution service module can subscribe to the first management and control device for the initial trigger event to obtain the target trigger event corresponding to the initial trigger event.

[0059] It should be noted that in the embodiment of the present application, after the policy execution service module subscribes to the first management and control device for the initial trigger event, the policy execution service module can convert the initial trigger event into the trigger event corresponding to the network layer through the first management and control device, and then can decompose the trigger event corresponding to the network layer to the second management and control device to determine the target trigger event corresponding to the initial trigger event.

[0060] It should be noted that in the embodiment of the present application, when the policy management module binds the target policy instance corresponding to the initial policy instance and the corresponding target service object, the policy management module can bind the target service object and the policy instance based on the type and identification information of the target service object corresponding to the target service object.

[0061] Further, in the embodiment of the present application, the policy management module can load the type and identification information of the initial service object from the first management and control device to the second management and control device, for example, the type and identification information of the initial service object can be decomposed from the first management and control device to the second management and control device to determine the type and identification information of the target service object.

[0062] It should be noted that in the embodiment of the present application, when the policy management module decomposes the type and identification information of the initial service object from the first management and control device to the second management and control device to determine the type and identification information of the target service object, the type and identification information of the initial service object can be decomposed from the first management and control device to the second management and control device to obtain the type and identification information of the second service object; through the second management and control device, the type and identification information of the second service object are adapted, converted and associated to obtain the type and identification information of the target service object.

[0063] Exemplarily, in the embodiments of the present application, the initial service object type and identification information (ID) need to be adapted, converted and associated to the corresponding network layer object type and identification information (ID) by the first management device, and then the network layer corresponding object type and identification information (ID) can be decomposed to obtain the type and identification information of the second service object by the second management device, and then the type and identification information of the second service object can be adapted, converted and associated by the second management device to obtain the type and identification information corresponding to the target service object.

[0064] Further, in the embodiments of the present application, after determining the type and identification information corresponding to the target service object, the policy management module can bind the target service object and the policy instance based on the type and identification information corresponding to the target service object.

[0065] It should be noted that, in the embodiments of the present application, Figure 4 The binding relationship between the policy instance and the target service object proposed in the embodiments of the present application is shown in the schematic diagram as Figure 4 The preset policy type can include a plurality of policy instances (policy instances 1, 2…n), and the policy management module can bind different policy instances and corresponding target service objects, for example, the policy instance 1 can be bound with the service objects 1, 2…j, and then the binding of a plurality of target service objects across domains or single domains can be realized, that is, the present application can create a plurality of policy instances and bind them with corresponding target service objects, so as to realize the flexible deployment of corresponding policy instances for service objects with different requirements.

[0066] Further, in the embodiments of the present application, the preset policy type can also include a policy execution service; when the target service object is processed in a closed loop, the policy execution service module can process the target service object through the policy service instance corresponding to the policy execution service and the first policy instance; wherein the first policy instance is determined through the identification information corresponding to the policy instance.

[0067] It should be noted that, in the embodiments of the present application, one policy execution service can create a plurality of policy service instances, which are responsible for the subscription, reception, analysis and processing of the trigger events of all service objects bound with the policy instance under the policy type. At the same time, it can be dynamically expanded according to the scale of the processed policy events.

[0068] It should be noted that in the embodiments of the present application, the policy event notification includes a policy event notification type, identification information corresponding to a policy instance, and identification information of a service object corresponding to the policy instance, so that the policy execution service module can determine the first policy instance based on the identification information corresponding to the policy instance in the received policy event notification, and determine the target service object through the identification information of the service object corresponding to the first policy instance.

[0069] Further, in the embodiments of the present application, when the policy execution service module performs closed-loop processing on the target service object corresponding to the first policy instance based on the policy event notification, the policy execution service module can perform policy processing logic according to the policy name information, the policy event type, the bound network or service object ID, and other policy attribute field values in the policy event notification, and perform corresponding actions. The execution action can be logging, manual alarm, or issuing a network management instruction through a network management layer, such as dynamically reducing or expanding the bandwidth of a specific service object. The type of the execution action is not limited in the present application.

[0070] It should be noted that in the embodiments of the present application, Figure 5 The closed-loop control policy implementation model diagram for the embodiments of the present application is shown in FIG. 1. Figure 5 As shown in FIG. 1, the preset policy type (policy type) can include a plurality of target policy instances (policy instance 1, 2…n). The policy management module can bind different target policy instances and corresponding target service objects. For example, the policy instance 1 can be bound with the service objects 1, 2…j. Or, the policy instance n can be bound with the service objects a, b…m. The preset policy type can include a policy execution service (policy service implementation). One policy execution service can create a plurality of policy service instances (policy service instance 1, 2…k). After any trigger event is triggered, a policy event notification can be received. Based on the identification information corresponding to the policy instance in the received policy event notification, the corresponding policy instance is determined, and the service object corresponding to the policy instance is determined. Then, the corresponding action is performed on the service object. The execution action can be logging, manual alarm, or issuing a network management instruction through a network management layer, such as dynamically reducing or expanding the bandwidth of a specific service object. That is, the present application can complete closed-loop control of a plurality of service objects based on different policy instances. The implementation process does not require a complex code framework, thereby reducing the complexity of closed-loop processing of the service object, and improving the network operation efficiency.

[0071] In conclusion, the application can bind multiple target policy instances to cross-domain or single-domain multiple service objects, thereby realizing flexible deployment of corresponding policy instances for different demand service objects, and further completing closed-loop control of multiple service objects based on different policy instances, and realizing the process without complex code framework, thereby reducing the complexity of closed-loop processing of service objects, and further improving network operation efficiency.

[0072] The embodiment of the application provides a service closed-loop control method, which is applied to a service closed-loop control system including a policy execution service module, and the method comprises the following steps: after a first trigger event is triggered, the policy execution service module receives a policy event notification; wherein the policy event notification comprises identification information corresponding to a policy event, a policy event notification type, and identification information of a policy instance; the policy execution service module determines the policy instance based on the identification information corresponding to the policy event, the policy event notification type, and the identification information of the policy instance; and the policy execution service module determines a target service object corresponding to the policy instance based on a corresponding relationship between the policy instance and the service object, and performs closed-loop processing on the target service object. As can be seen, the policy execution service module can determine the policy instance based on the identification information corresponding to the policy event in the policy event notification, the policy event notification type, and the identification information of the policy instance, and further determine the target service object corresponding to the policy instance based on the corresponding relationship between the policy instance and the service object, and perform closed-loop processing on the target service object, that is, the application can complete closed-loop control of multiple service objects based on different policy instances, and the implementation process does not require a complex code framework, thereby reducing the complexity of closed-loop processing of service objects, and further improving network operation efficiency.

[0073] Embodiment two

[0074] Based on the above embodiment, another embodiment of the application provides a service closed-loop control method, which can realize a method and system (service closed-loop control system) for simultaneously implementing multiple closed-loop control policies on cross-domain or single-domain multiple service objects in an end-to-end network environment, so as to ensure that the network or service can be automatically operated with high performance, high reliability, and scalability, thereby reducing the operation complexity of operation personnel, without the need for users to know the technical details of the network or service, and improving user experience; wherein corresponding closed-loop control policies are designed and defined for different demand scenarios, including network optimization policies, business SLA guarantee policies, etc. Each closed-loop control policy can bind multiple service objects, including service connections, network element devices, etc., to realize closed-loop control of the objects.

[0075] It should be noted that, in the embodiments of the application, Figure 6 Service closed-loop control system structure diagram provided by the embodiment of the application Figure Two For example, Figure 6As shown, the network service closed-loop control system based on the policy model is composed of a closed-loop policy design and definition module (policy definition module), a closed-loop policy management module (policy management module), a closed-loop policy execution service module (policy execution service module), a network management and control module, and a cross-domain network service object, wherein: the closed-loop policy design and definition module (policy definition module) is responsible for the definition of policy types for different demand scenarios and the instantiation of the policy types, each policy type including configuration parameters, trigger events, policy execution logic, and policy execution services. The closed-loop policy management module is responsible for the lifecycle management of the creation, deployment, update, and deletion of the closed-loop policy execution service, the loading, update, and deletion of different closed-loop policy instances, and the binding and unbinding of the closed-loop policy instances and the network service object. The closed-loop policy execution service module is responsible for policy trigger event subscription, reception, and processing; the execution service type can be event analysis, decision, or network management and control action; it is composed of multiple instances. The network management and control module is responsible for the management and control of the network or network service, including the configuration, discovery, and reporting of policy events related to specific service or network objects. The network service or device object is a network service or network device created for users.

[0076] It should be noted that in the embodiments of the present application, different policy types (preset policy types) are designed and defined for different closed-loop control demand scenarios, and multiple different policy instances (initial policy instances) are created based on the policy types (preset policy types) to meet the needs of users of different grades (high, medium, and low). Different policies (initial policy instances) are loaded into the network and bound to different network or service objects. Each policy service type develops a corresponding policy execution service and deploys multiple instances. The policy execution service issues and configures the trigger events defined by the policy type to the network, subscribes to, receives, analyzes, and processes the trigger events of different network or service objects bound by different policies from the network, and calls the network management and control device to perform corresponding actions.

[0077] Further, in the embodiments of the present application, one policy type can describe an action to be performed when a specific event occurs in the network or service in a specific scenario. A policy type includes configuration parameters, trigger events, policy execution logic, and execution services, etc., for example, for user network service level agreement (SLA) guarantee, an "SLA guarantee policy type" (preset policy type) can be defined. The parameters include policy name, ID, description, etc.; the trigger event (initial trigger event) is the network or service event that triggers the execution of the policy, which can be a set of monitored content (such as bandwidth, latency, etc.) and a set threshold value, when the monitored content value meets a specific condition (such as bandwidth usage exceeding or being lower than the set threshold value), the related event is triggered, the trigger event can be of multiple types or values; the policy execution logic is to analyze, judge and decide based on the comprehensive information of different types of trigger event types or values, policy instance name / ID, policy instance binding service object, etc., and perform related actions, for example, dynamic resource expansion or alarm, or even more complex data collection, artificial intelligence (AI) analysis, decision making, etc.; the execution service is the action of the policy on the network or service, including network management and control actions, such as implementing network resource dynamic expansion, etc.

[0078] It should be noted that in the embodiments of the present application, the policy type definition can be described in a standardized, manufacturer-independent and implementation-independent high-level language, such as Topology and Orchestration Specification for Cloud Applications (TOSCA), etc., and the language type is not limited in the present application.

[0079] It should be noted that in the embodiments of the present application, the policy service implementation is a deployable and executable application service corresponding to the policy type (preset policy type), which can be a process or a container service. The policy service issues and configures, subscribes and receives the trigger events of the policy type definition, executes the policy logic, and performs the policy action, etc. One policy type defines one policy service, but there can be multiple instances of policy service implementation when deployed.

[0080] It should be noted that in the embodiments of the present application, policy instantiation is based on the designed and defined policy type to formulate specific policies for different objects including networks, services, etc., including parameter assignment, trigger event type and threshold definition. One policy type (preset policy type) can have multiple policy instances (initial policy instances) or policies. For example, in the SLA service guarantee scenario, a user purchases the "VIP SLA guarantee" package, and for the package type service, the "VIP SLA guarantee" policy needs to be formulated for the network service subscribed by the user. The trigger event of this policy is that when the maximum bandwidth usage reaches 70%, the service bandwidth needs to be dynamically expanded by 1 times. When the user purchases the "premium SLA guarantee" package, for the package type service, the "premium SLA guarantee" policy needs to be formulated for the network service subscribed by the user. The trigger event of this policy is that when the maximum bandwidth usage reaches 90%, the service bandwidth needs to be dynamically expanded by 0.5 times. Therefore, the "VIP SLA guarantee" policy and the "premium SLA guarantee" policy are two instances of the "SLA guarantee policy type", which have different parameter values, event trigger thresholds, etc., to meet the service needs of users of different levels.

[0081] Further, in the embodiments of the present application, the policy management module can be responsible for policy (initial policy instance) loading and network service object binding. The policy (initial policy instance) needs to be loaded to the specified network domain, administrative region and network device through the network management module to take effect, and the policy (policy instance) needs to be bound to different network or service objects. One policy (policy instance) can bind multiple objects. The policy (initial policy instance) loading and object binding are loaded from the User oriented services (CFS) layer / end-to-end service layer to different technical domains such as Internet Protocol (IP), transmission domain and bound to network or service objects. In different technical domains, policy loading and object binding are gradually decomposed to sub-domain management devices (second management devices) through cross-domain management devices (first management devices), loaded to the sub-domains contained in the domain, and bound to the corresponding network or service objects of the sub-domains.

[0082] It should be noted that in the embodiments of the present application, when the policy management module decomposes the type and identification information of the initial service object from the cross-domain management device (first management device) to the sub-domain management device (second management device) to determine the type and identification information corresponding to the target service object, the type and identification information of the initial service object can be associated from the cross-domain management device (first management device) to the service object type and identification information corresponding to the network layer based on the association relationship; then the service object type and identification information corresponding to the network layer can be decomposed to the sub-domain management device (second management device), and the type and identification information corresponding to the target service object can be determined.

[0083] Exemplarily, in the embodiment of the present application, when the policy object is bound, the service object type (initial service object type) and ID (identification information) need to be adapted, converted and associated to the corresponding network layer object type and ID by the cross-domain management device (the first management device), and gradually decomposed to the sub-domain management device (the second management device); the sub-domain management device (the second management device) further adapts, converts and associates the corresponding network object to the object type (target service object type) and ID (identification information) of the corresponding device.

[0084] It should be noted that in the embodiment of the present application, the cross-domain management and the sub-domain layer can be nested with multiple layers of management devices, and each pair of upper and lower layers is a cross-domain management layer and a sub-domain layer.

[0085] It should be noted that in the embodiment of the present application, when the policy is loaded, the trigger event (initial trigger event) in the policy type definition needs to be adapted and converted to the corresponding network event type by the cross-domain management device (the first management device), and gradually decomposed and configured to each sub-domain management layer, and the network event type is adapted, converted and configured to the device event (target trigger event) of the corresponding device by the sub-domain management layer.

[0086] That is, in the embodiment of the present application, the preset policy type can include multiple target policy instances, and the policy management module can bind different target policy instances and corresponding target service objects, so as to bind multiple target service objects in the cross-domain or single domain, that is, the present application can create multiple target policy instances and bind them with corresponding target service objects, so as to realize flexible deployment of corresponding policy instances for service objects with different requirements.

[0087] It should be noted that in the embodiment of the present application, the policy management module can be responsible for the deployment of the policy execution service, including the creation, expansion, suspension, release and other life cycle management of the policy execution service instance. One policy execution service can create multiple instances, and is responsible for the subscription, reception, analysis and processing of the trigger event of all service objects bound by the policy under the policy type; at the same time, it can be dynamically expanded according to the scale of the processed policy event.

[0088] It should be noted that in the embodiments of the present application, the policy execution service (policy execution service module) can subscribe to trigger events of different technical domains cross-domain management layers, the cross-domain management layer subscribes to trigger events of its sub-domain management layer, and the sub-domain management layer subscribes to trigger events of the related device. After the policy execution service receives the subscribed policy event, the policy execution service performs policy processing logic according to the policy name information, policy event type, bound network or service object ID, and other policy attribute field values in the policy event notification, and performs the corresponding action. The execution action can be logging, manual alarm, or network management instruction issued through the network management layer, such as dynamic bandwidth expansion of a specific service object.

[0089] That is, in the embodiments of the present application, as shown in Figure 5 The preset policy type (policy type) can include a plurality of target policy instances (policy instance 1, 2…n), and the policy management module can bind different target policy instances and corresponding target service objects, for example, policy instance 1 can be bound with service objects 1, 2…j; or policy instance n can be bound with service objects a, b…m. The preset policy type can include a policy execution service (policy service implementation), and one policy execution service can create a plurality of policy service instances (policy service instance 1, 2…k). After any trigger event is triggered, the policy event notification can be received, the corresponding policy instance is determined based on the identification information of the received policy event notification corresponding to the policy instance, and the service object corresponding to the policy instance is determined, and then the corresponding action is performed on the service object. The execution action can be logging, manual alarm, or network management instruction issued through the network management layer, such as dynamic bandwidth expansion of a specific service object. That is, the present application can complete closed-loop control of a plurality of service objects based on different policy instances, and the implementation process does not require a complex code framework, thereby reducing the complexity of closed-loop processing of the service object, and improving the network operation efficiency.

[0090] In summary, the present application can bind a plurality of target policy instances to a plurality of service objects across domains or in a single domain, thereby realizing flexible deployment of corresponding policy instances for service objects with different needs, and then completing closed-loop control of a plurality of service objects based on different policy instances. The implementation process does not require a complex code framework, which can reduce the complexity of closed-loop processing of the service object, and thereby improve the network operation efficiency.

[0091] The embodiment of the application provides a service closed loop control method, which is applied to a service closed loop control system, and the service closed loop control system comprises a policy execution service module. The method comprises the following steps: after a first trigger event is triggered, the policy execution service module receives a policy event notification; wherein the policy event notification comprises identification information corresponding to a policy event, a policy event notification type, and identification information of a policy instance; the policy execution service module determines the policy instance based on the identification information corresponding to the policy event, the policy event notification type, and the identification information of the policy instance; and the policy execution service module determines a target service object corresponding to the policy instance based on a corresponding relationship between the policy instance and the service object, and performs closed loop processing on the target service object. Therefore, the policy execution service module can determine the policy instance based on the identification information corresponding to the policy event in the policy event notification, the policy event notification type, and the identification information of the policy instance, and then can determine the target service object corresponding to the policy instance based on the corresponding relationship between the policy instance and the service object, and perform closed loop processing on the target service object. That is, the application can complete closed loop control on multiple service objects based on different policy instances, and the implementation process does not require a complex code framework, thereby reducing the complexity of closed loop processing on the service object, and further improving network operation efficiency.
