[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] Industrial networks require good isolation and network performance, so they are usually carried on private networks based on network slicing. Network slicing is implemented based on a bandwidth reservation mechanism, so when business traffic is low, bandwidth resources will be idle.

[0074] Since network slicing is implemented based on configuration delivery, the relevant technology manually adjusts the bandwidth configuration of the network slice corresponding to the service, and then adjusts the bandwidth of the network slice allocated to the service based on the bandwidth configuration of the network slice to achieve efficient utilization of bandwidth resources. However, this requires frequent changes in device configuration, and changing the bandwidth configuration of the network slice will interrupt the network traffic being transmitted within the network slice, affecting service stability and user service experience.

[0075] An embodiment of the present application provides a network resource configuration method, which pre-divides an industrial network dedicated network into multiple network sub-slices of small granularity, and dynamically configures at least one network sub-slice for a target business from multiple network sub-slices in response to resource configuration information issued by a management and control system. The configuration process of the network sub-slices does not affect the stability of the target business, thereby ensuring the stability of the target business, and the bandwidth resources configured for the target business vary with the number of configured network sub-slices, thereby greatly improving the utilization rate of network resources.

[0076] The network resource configuration method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the network device 102 communicates with the management and control system 104 through the network. The data storage system can store the data that the management and control system 104 needs to process. The data storage system can be integrated on the management and control system 104, or it can be placed on the cloud or other network servers. Among them, the network device 102 can be, but is not limited to, a PE (Provider Edge device) device in the backbone network, a life device (leaf device, such as a leaf switch) in the metropolitan area network, etc. The management and control system 104 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0077] In an exemplary embodiment, Figure 2 As shown, a network resource configuration method is provided, which is applied to Figure 1 The network device 102 in the example is used as an example to illustrate, including the following steps 202 to 204. Among them:

[0078] Step 202: receiving resource configuration information issued by the management and control system for the target service, where the resource configuration information is used to indicate the configuration of a network sub-slice for the target service;

[0079] Step 204: configure at least one network sub-slice for the target service based on the resource configuration information, and import the network traffic of the target service into at least one network sub-slice associated with the target service.

[0080] In the embodiment of the present application, the industrial network private network can be pre-divided into multiple network sub-slices as needed. The sizes of the bandwidth resources corresponding to the network sub-slices can be the same or different, and the division method and division granularity are not specifically limited in the embodiment of the present application.

[0081] The management and control system can obtain the resource requirements corresponding to the target business, and can send resource configuration information for the target business to the network device based on the resource requirements of the target business. The resource configuration information is used to instruct the network device to configure at least one network sub-slice for the target business.

[0082] In one example, the user can manually set the resource requirements corresponding to the target business in the management and control system, for example, setting the bandwidth required for the target business, or setting the business requirements corresponding to the target business, such as throughput, delay, etc. The management and control system determines the bandwidth required for the target business based on the business requirements. The management and control system can then send resource configuration information to the network device based on the bandwidth required for the target business.

[0083] For example, the resource configuration information may include the bandwidth required by the target service. The network device determines the number of network sub-slices required for the target service based on the bandwidth required by the target service, and configures a corresponding number of network sub-slices for the target service.

[0084] For example, the management and control system can determine the number of network sub-slices required for the target business based on the bandwidth required by the target business. The resource configuration information can include the number of network sub-slices required for the target business, and the network device can configure a corresponding number of network sub-slices for the target business in response to the resource configuration information.

[0085] In another example, the management and control system can monitor the resource requirements of the target business in real time. For example, a pre-trained resource prediction model is used to determine the resource size required by the target business in the future, such as the required bandwidth size or the required number of network sub-slices, etc. Then, the management and control system can send resource configuration information to the network device based on the bandwidth size required by the target business or the required number of network sub-slices. After receiving the resource configuration information, the network device can dynamically adjust the number of network sub-slices for the target business based on the resource configuration information, including increasing or decreasing network sub-slices for the target business, so as to configure a corresponding number of network sub-slices for the target business.

[0086] In the above-mentioned network resource configuration method, the network device can receive the resource configuration information issued by the management and control system for the target service, and the resource configuration information is used to indicate the configuration of the network sub-slice for the target service, and then the network device can configure at least one network sub-slice for the target service based on the resource configuration information, and import the network traffic of the target service into at least one network sub-slice associated with the target service. Using the network resource configuration method provided by the embodiment of the present application, the network device can configure at least one network sub-slice for the target service in response to the resource configuration information, that is, the embodiment of the present application can dynamically adjust the network sub-slice configured for the target service based on the resource configuration information, so as to adjust the size of the bandwidth resources configured for the target service by adjusting the number of network sub-slices configured for the target service, which can greatly improve the utilization rate of network resources, and the embodiment of the application itself does not need to adjust the bandwidth configuration of the network slice, so the adjustment process does not affect the stability of the target service, and thus the stability of the target service can be guaranteed.

[0087] In an exemplary embodiment, the resource configuration information includes first resource configuration information, referring to Figure 3 In step 104, configuring at least one network sub-slice for the target service based on the resource configuration information may include the following steps 302 to 304, wherein:

[0088] Step 302: determining at least one initial network sub-slice corresponding to the target service based on the first resource configuration information;

[0089] Step 304: establish an association relationship between the target service and at least one initial network sub-slice, and update the service mode of each initial network sub-slice according to the target service.

[0090] In an embodiment of the present application, the management and control system can send first resource configuration information for the target service to the network device based on the user's resource configuration for the target service. As described in the above embodiments, the user can manually set the resource requirements corresponding to the target service in the management and control system, for example: setting the bandwidth required for the target service, or setting the service requirements corresponding to the target service, such as throughput, delay, etc., and the management and control system determines the bandwidth required for the target service based on the service requirements. Then the management and control system can send the first resource configuration information to the network device based on the bandwidth required for the target service.

[0091] In one example, the first resource configuration information may include the bandwidth size required by the target service. The network device determines the number of initial network sub-slices required by the target service based on the bandwidth size required by the target service and the granularity of the network sub-slice division (the bandwidth resources corresponding to the network sub-slice), and configures the corresponding number of initial network sub-slices for the target service. For example: the number of initial network sub-slices = the ratio of the bandwidth size required by the target service to the bandwidth resource size corresponding to the network sub-slice.

[0092] In another example, the management and control system can determine the number of initial network sub-slices required for the target business based on the bandwidth size required by the target business and the granularity of the network sub-slice division. The first resource configuration information may include the number of initial network sub-slices required for the target business, and the network device can configure a corresponding number of initial network sub-slices for the target business in response to the resource configuration information.

[0093] The above two examples are based on the uniform division of network sub-slices. In fact, network sub-slices can also be divided in a non-uniform manner. In the non-uniform division method, the bandwidth resource sizes corresponding to each network sub-slice can be different. Therefore, the network device or the management and control system can also determine the initial network sub-slice corresponding to the target service from each network sub-slice based on the bandwidth resource size corresponding to each network sub-slice and the bandwidth size required by the target service. The sum of the bandwidth resources corresponding to the initial network sub-slice is not less than the bandwidth size required by the target service. Then the network device can directly configure each initial network sub-slice for the target service.

[0094] In the process of configuring the initial network sub-slice for the target service, the network device can directly establish an association between the target service and the initial network sub-slice, and change the service mode corresponding to the initial network sub-slice based on the target service. For example, when the target service is a production service, the service mode corresponding to the initial network sub-slice can be changed to a deterministic forwarding mode; or, when the target service is a management service, the service mode corresponding to the initial network sub-slice can be changed to an IP forwarding mode.

[0095] After completing the configuration of the initial network sub-slice of the target service, the traffic data of the target service can be introduced into the initial network sub-slice corresponding to the target service through SRv6 (Segment Routing over IPv6, segment routing based on IPv6) and other methods.

[0096] In an exemplary embodiment, referring to Figure 4 As shown, the above method may further include steps 402 to 406, wherein:

[0097] Step 402, counting the bandwidth utilization of each network sub-slice associated with the target service;

[0098] Step 404: Send bandwidth monitoring information to the management and control system based on the bandwidth utilization of each network sub-slice;

[0099] Step 406, receiving the second resource configuration information issued by the management and control system, the second resource configuration information is generated by the management and control system based on the predicted resource occupancy data of the target business, and the predicted resource occupancy data is obtained according to the bandwidth utilization prediction of each network sub-slice.

[0100] In an embodiment of the present application, after the network device configures at least one network sub-slice for the target service, it can count the bandwidth utilization of each network sub-slice associated with the target service according to a preset statistical period, and can send bandwidth monitoring information to the management and control system based on the bandwidth utilization of each network sub-slice.

[0101] After the management and control system receives the bandwidth monitoring information sent by the network device, it can predict the predicted resource occupancy data of the target service based on the bandwidth utilization of each network sub-slice. The predicted resource occupancy data may be the resource data required by the target service in a period of time in the future, and may include the bandwidth resources required in the future (for clear description, referred to as predicted bandwidth resources in the following embodiments) or the number of network sub-slices required (for clear description, referred to as predicted number in the following embodiments).

[0102] In one example, the management and control system can predict the predicted bandwidth resources for the target business based on the bandwidth utilization of each network sub-slice.

[0103] Exemplarily, the management and control system may send second resource configuration information for the target service to the network device based on the predicted bandwidth resources of the target service, and the second resource configuration information may include the predicted bandwidth resources of the target service.

[0104] Alternatively, the management and control system can determine the number of network sub-slices required by the target business in the future (for clear description, referred to as the predicted number in the following embodiments) based on the predicted bandwidth resources of the target business and the division granularity of the network sub-slices, and send second resource configuration information for the target business to the network device based on the predicted number. The second resource configuration information may include the predicted number of network sub-slices required for the target business.

[0105] In another example, the management and control system may predict the predicted number of network sub-slices required for the target service based on the bandwidth utilization of each network sub-slice. Exemplarily, the management and control system may send second resource configuration information for the target service to the network device based on the predicted number, and the second resource configuration information may include the predicted number of network sub-slices required for the target service.

[0106] Alternatively, after obtaining the predicted number of network slices required for the target business, the management and control system can determine the number of network sub-slices that need to be increased or decreased for the target business based on the predicted number of network sub-slices required for the target business and the number of network sub-slices currently associated with the target business, and based on the number of network sub-slices that need to be increased or decreased, send second resource configuration information for the target business to the network device, which may include the number of network sub-slices that need to be increased or decreased for the target business.

[0107] After the network device receives the second resource configuration information, it can dynamically adjust the network sub-slices of the target service based on the second resource configuration information, for example: adjusting the number of network sub-slices of the target service.

[0108] In an exemplary embodiment, the resource configuration information includes second resource configuration information, referring to Figure 5 As shown, in step 104, configuring at least one network sub-slice for the target service based on the resource configuration information may include steps 502 to 506, wherein:

[0109] Step 502: determining at least one target network sub-slice corresponding to the target service and a processing method for the at least one target network sub-slice based on the second resource configuration information;

[0110] Step 504: When the processing method is to add a sub-slice, an association relationship between the target service and at least one target network sub-slice is established, and a service mode of each target network sub-slice is updated according to the target service;

[0111] Step 506: When the processing method is to release the sub-slice, delete the association between the target service and at least one target network sub-slice.

[0112] In one example, the second resource configuration information may include the predicted bandwidth resources of the target service, and the network device may determine the number of network sub-slices (i.e., the predicted number) required by the target service in the future based on the predicted bandwidth resources of the target service and the granularity of the network sub-slice division; or the second resource configuration information may include the predicted number of target sub-slices required by the target service, and the network device may directly obtain the predicted number from the second resource configuration information. Furthermore, the network device may determine at least one target network sub-slice corresponding to the target service and a processing method for at least one target network sub-slice based on the number of network sub-slices currently associated with the target service and the predicted number.

[0113] For example: determine the difference between the predicted number and the number of network sub-slices associated with the target business. When the predicted number is greater than the number of network sub-slices associated with the target business, the difference target network sub-slices can be determined from idle network sub-slices or network sub-slices preempted from other businesses, and the processing method for the difference target network sub-slices is to add sub-slices; or, when the predicted number is less than the number of network sub-slices associated with the target business, the difference target network sub-slices can be determined from the network sub-slices associated with the target business, and the processing method for the difference target network sub-slices is to release sub-slices.

[0114] In another example, the second resource configuration information may include the number of network sub-slices that need to be increased or decreased by the target business. For example, the second resource configuration information carries the number and an increase or decrease flag. When the increase or decrease flag indicates an increase, the number of target network sub-slices can be determined from idle network sub-slices or network sub-slices seized from other businesses, and the processing method for the number of target network sub-slices is to increase sub-slices. When the increase or decrease flag indicates a decrease, the number of target network sub-slices can be determined from network sub-slices associated with the target business, and the processing method for the number of target network sub-slices is to release sub-slices.

[0115] When the processing method is to add sub-slices, the network device can establish an association relationship between the target service and each target network sub-slice, and update the service mode of each target network sub-slice according to the target service. For example, in the case of the production service of the target service, the service mode of each target network sub-slice can be changed to a deterministic forwarding mode, or in the case of the management service of the target service, the service mode of each target network sub-slice can be changed to an IP forwarding mode.

[0116] When the processing method is to release the sub-slice, the network device can delete the association between the target service and each target network sub-slice, and the subsequent service traffic data of the target service will not be imported into each target sub-slice. In this way, the target network sub-slice can be released for use by other services.

[0117] In an exemplary embodiment, Figure 6 As shown, a network resource configuration method is provided, which is applied to Figure 1 Taking the control system 104 in FIG. 1 as an example, the method includes the following steps 602. Among them:

[0118] Step 602: Send resource configuration information for the target service to the network device, where the resource configuration information is used to instruct the network device to configure at least one network sub-slice for the target service.

[0119] In an embodiment of the present application, the management and control system can obtain the resource requirements corresponding to the target business, and can send resource configuration information for the target business to the network device based on the resource requirements of the target business. The resource configuration information is used to instruct the network device to configure at least one network sub-slice for the target business.

[0120] Among them, the process of the network device configuring at least one network sub-slice for the target service in response to the resource configuration information can be referred to the relevant description of the aforementioned embodiment, and will not be repeated here in the embodiments of the present application.

[0121] By adopting the network resource configuration method provided in the embodiment of the present application, the network device can configure at least one network sub-slice for the target service in response to the resource configuration information. That is, the embodiment of the present application can dynamically adjust the network sub-slice configured for the target service based on the resource configuration information, so as to adjust the size of the bandwidth resources configured for the target service by adjusting the number of network sub-slices configured for the target service, which can greatly improve the utilization rate of network resources. The embodiment of the application itself does not need to adjust the bandwidth configuration of the network slice, so the adjustment process does not affect the stability of the target service, and thus the stability of the target service can be guaranteed.

[0122] In an exemplary embodiment, referring to Figure 7 As shown, the resource configuration information includes first resource configuration information, referring to Figure 7 As shown, in step 602, sending resource configuration information for the target service to the network device may include the following steps 702 to 704, wherein:

[0123] Step 702: Determine initial network sub-slice information corresponding to the target service in response to the demand information of the target service;

[0124] Step 704: Send first resource configuration information to the network device based on the initial network sub-slice information, where the first resource configuration information is used to instruct the network device to configure at least one initial network sub-slice for the target service.

[0125] In the embodiment of the present application, the user can manually set the demand information corresponding to the target service in the management and control system, for example, setting the bandwidth required for the target service, or setting the service requirements corresponding to the target service, such as throughput, delay, etc., and the management and control system determines the bandwidth required for the target service based on the service requirements. Then, the management and control system can determine the initial network sub-slice information corresponding to the target service based on the bandwidth resources required for the target service, and send the first resource configuration information to the network device based on the initial network sub-slice information.

[0126] Exemplarily, the management and control system can directly determine the bandwidth resources required by the target business as the initial sub-slice information corresponding to the target business, that is, the first resource configuration information includes the bandwidth resources required by the target business.

[0127] Alternatively, the management and control system can determine the number of initial network sub-slices required for the target business based on the bandwidth resources required for the target business and the granularity of the network sub-slice division, and use the number of initial network sub-slices as the information of the initial sub-slices. The first resource configuration information can include the number of initial network sub-slices required for the target business.

[0128] Alternatively, the management and control system may also determine the initial network sub-slice corresponding to the target service from each network sub-slice based on the bandwidth resource size corresponding to each network sub-slice and the bandwidth size required for the target service, and use the sub-slice identifier corresponding to the initial network sub-slice as the initial network sub-slice information. The first resource configuration information may include the sub-slice identifiers of each initial network sub-slice.

[0129] In an exemplary embodiment, the resource configuration information includes second resource configuration information, referring to Figure 8 As shown, in step 602, sending resource configuration information for the target service to the network device may include the following steps 802 to 806, wherein:

[0130] Step 802: Receive bandwidth monitoring information sent by a network device, where the bandwidth monitoring information includes bandwidth utilization of each network sub-slice associated with the target service;

[0131] Step 804: Input the bandwidth utilization of each network sub-slice into the resource prediction model to obtain predicted resource occupancy data corresponding to the target service;

[0132] Step 806: Send second resource configuration information to the network device based on the predicted resource occupancy data corresponding to the target service. The second resource configuration information is used to instruct the network device to dynamically adjust the network sub-slice associated with the target service.

[0133] In an embodiment of the present application, the management and control system can receive bandwidth monitoring information sent by the network device, and can input the bandwidth utilization rate of each network sub-slice associated with the target service carried by the bandwidth monitoring information into a pre-trained resource prediction model, so as to predict the predicted resource occupancy data corresponding to the target service in a period of time in the future, which may include the bandwidth resources required in the future period of time (for clear description, referred to as predicted bandwidth resources in the following embodiments) or the number of network sub-slices required (for clear description, referred to as predicted number in the following embodiments), and then can send the second resource configuration information to the network device according to the predicted resource occupancy data corresponding to the target service. The specific process may refer to the relevant description of the aforementioned embodiment, and will not be repeated here in the embodiment of the present application.

[0134] Among them, the resource prediction model can be implemented using the TD-MPC (Temporal Difference learning for Model Predictive Control, a model predictive control algorithm based on reinforcement learning) model. The TD-MPC model is a reinforcement learning method that combines temporal difference learning (TD) and model predictive control (MPC). It uses model predictive control (MPC) to perform multi-step prediction and optimization in the learned environment model, and combines the temporal difference method to update the model and strategy.

[0135] Reference Fig. 9 As shown, the training process of the resource prediction model is shown.

[0136] First, a training set can be constructed. For example, a corresponding number of network sub-slices can be configured for each service in advance based on the service requirements of each service, and the bandwidth utilization corresponding to each network sub-slice can be recorded, and training samples can be constructed based on the number of network sub-slices configured for each service and the bandwidth utilization corresponding to each network sub-slice to obtain a sample set.

[0137] The initial resource prediction model is trained based on the sample set. Exemplarily, for any training sample, the number of network sub-slices and the bandwidth utilization corresponding to each network sub-slice can be input into the initial resource prediction model to predict the number of network sub-slices required by the service in the future, and resource configuration information can be sent to the network device based on the number of network sub-slices, so that the network device adjusts the number of network sub-slices associated with the service based on the resource configuration information, and counts the bandwidth utilization of each network sub-slice associated with the service, and feeds back the bandwidth utilization of each network sub-slice to the management and control system.

[0138] The management and control system can determine the prediction score of the initial resource prediction model based on the bandwidth utilization of each network sub-slice. The prediction score is used to characterize the accuracy of the model prediction and can be positively correlated with the bandwidth utilization of each network sub-slice, that is, the higher the bandwidth utilization corresponding to each network sub-slice, the higher the corresponding prediction score. The management and control system can update the network parameters of the initial resource prediction model online based on the prediction score of the initial resource prediction model, and repeat the above process until the prediction accuracy of the initial resource prediction model meets the training requirements, for example, until the prediction score of the initial resource prediction model reaches the score threshold.

[0139] It should be noted that the embodiments of the present application may adopt online training or offline training. There is no specific limitation on this in the embodiments of the present application. When online training is adopted, the number of network sub-slices corresponding to each service and the bandwidth utilization of each network sub-slice can be recorded after each round of training, and added to the sample set as a new training sample to participate in the next round of training.

[0140] In an exemplary embodiment, Figure 1 As shown, a network resource configuration system is provided, the network resource configuration system includes a network device 102 and a management and control system 104, wherein:

[0141] The management and control system 104 is used to send resource configuration information for the target service to the network device, where the resource configuration information is used to instruct the network device to configure at least one network sub-slice for the target service;

[0142] Network device 102 is used to receive resource configuration information issued by the management and control system for the target business, configure at least one network sub-slice for the target business based on the resource configuration information, and import the network traffic of the target business into at least one network sub-slice associated with the target business.

[0143] It should be noted that the operations performed by the management and control system 104 and the network device 102 in the embodiment of the present application, as well as the technical effects that can be achieved, can be referred to the relevant description of the aforementioned embodiment, and will not be repeated here in the embodiment of the present application.

[0144] In order to enable those skilled in the art to better understand the embodiments of the present application, the embodiments of the present application are described below through specific examples.

[0145] The embodiment of the present application proposes a network resource configuration system for industrial network scenarios. This system is different from the previous method of directly changing the slice bandwidth. By deploying a multimodal slice intelligent allocation module on the network device, the service can be associated with multiple small-grained network sub-slices, and the service mode of the network sub-slice and the association between the service and the network sub-slice are changed based on the multimodal device capabilities to achieve the adjustment of the service bandwidth. At the same time, the system combines the TD-MPC model in the management and control system to predict the number of network sub-slices required for the service in real time, and inform the network equipment to perform intelligent tuning of the service bandwidth.

[0146] The management and control system combines the TD-MPC model to generate the number of network sub-slices required to be allocated to each service in the next time period, and can update the model online based on actual application conditions.

[0147] A multimodal intelligent slice allocation module can be deployed in network equipment: ① According to the results issued by the management and control system, the number of network sub-slices corresponding to the business is adjusted; ② Relying on the multimodal capabilities of the network equipment, the business mode of the network sub-slice is adjusted to the required mode to achieve bandwidth adjustment of the business slice; ③ Introduce the business into the newly added / reduced network small slices.

[0148] For example, refer to Fig.10 As shown, the configuration process of network resources may include:

[0149] S1: Divide the industrial network into multiple network sub-slices at a small granularity.

[0150] S2: Allocate network sub-slices to corresponding services based on the initially estimated service requirements.

[0151] S3: The network device changes the network sub-slice to the required service mode: for production services, the network sub-slice is adjusted to the deterministic forwarding mode; for management services, the network sub-slice is adjusted to the IP forwarding mode.

[0152] S4: Associate network sub-slices with corresponding services: Introduce services into corresponding network sub-slices based on SRv6 and other methods.

[0153] S5: The management and control system monitors the bandwidth usage of each service, and combines the resource prediction model to predict the number of network sub-slices required for each service in the next time period. The management and control system informs the network equipment to dynamically adjust the number of network sub-slices allocated to the service, realizing intelligent tuning of the service slice bandwidth.

[0154] The embodiment of the present application does not need to frequently change the slice bandwidth configuration, and by changing the sub-slice mode and the relationship between the service and the network sub-slice, the service bandwidth can be adjusted to avoid affecting the running service status. At the same time, the TD-MPC model is combined with the management and control platform to predict the number of network sub-slices required for the service in real time, realize intelligent optimization of service bandwidth, effectively improve network bandwidth utilization, and achieve user-unawareness, thereby improving service experience.
