Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a resource allocation method and apparatus. Background Art

[0002] Currently, the services supported by network devices in a communication network (such as access switches, aggregation switches, wireless local area network access points (WLAN APs), or wireless access controllers (WACs), etc.) include basic telecommunications services and other services. Among them, the basic telecommunications services include: access of user equipment or packet forwarding, etc. Other services include services such as user identity verification, smart application control (SAC), deep packet inspection (DPI), or artificial intelligence (AI) big data analysis.

[0003] When there are relatively many basic telecommunications services of a network device, enabling other services will cause excessive consumption of the resources of the network device (such as processors, caches, memory, or disk bandwidth, etc.). In this way, it will affect the basic telecommunications services such as access of normal user equipment or packet forwarding of the network device, and further affect the user's network usage experience. Summary of the Invention

[0004] Embodiments of this application provide a resource allocation method and apparatus, which helps to reduce the resource consumption of network devices and improve the user's network usage experience.

[0005] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a resource allocation method is provided. The method is executed by a network controller and includes: receiving a request message from a first network device, where the request message is used to request available resources for a to-be-processed service; determining a second network device from one or more network devices other than the first network device according to the request message, where the second network device has first available resources capable of processing the to-be-processed service; and sending first identification information of the second network device to the first network device. The to-be-processed service is any one of the other services described in the background art. In this way, when the network controller determines that the second network device has first available resources capable of processing the to-be-processed service according to the request message of the first network device, the network controller can send the first identification information of the second network device to the first network device, thereby instructing the first network device to transfer the to-be-processed service of the first network device to the second network device for processing, which helps reduce the resource consumption of the first network device and improve the network usage experience of the user equipment connected to the first network device (i.e., improve the user experience). At the same time, the idle resources of the second network device can be utilized, improving the resource utilization efficiency. It can be understood that when there are relatively many basic telecommunications services on the first network device, the to-be-processed services (i.e., the other services described in the background art) of the first network device will cause the resource consumption of the first network device to be too high. At this time, the first network device can request resources from the network controller and send its to-be-processed services to the second network device that can provide resources for processing, thereby reducing the resource consumption of the first network device and improving the network usage experience of the user equipment accessing the first network device.

[0007] According to the first aspect, in a first possible implementation manner, the request message includes resource information required for the to-be-processed service, and the resource information includes a resource type and a resource quantity; or, the request message includes the type of the to-be-processed service and the quantity of the to-be-processed service. The type of the to-be-processed service includes user identity verification, SAC, DPI, or AI big data analysis, etc. In this way, when the request message includes the resource information required for the to-be-processed service, the network controller can determine the second network device according to the resource information required for the to-be-processed service, without obtaining the resource information required for the to-be-processed service according to the type of the to-be-processed service and the quantity of the to-be-processed service, improving the efficiency of the network controller in determining the second network device.

[0008] According to the first aspect or the first possible implementation manner of the first aspect, in a second possible implementation manner, when the request message includes the resource information required for the to-be-processed service, the resource type includes at least one of a computing resource type or a storage resource type.

[0009] According to any one of the first aspect to the second possible implementation manner of the first aspect, in the third possible implementation manner, when the request message includes the type of the service to be processed and the quantity of the service to be processed, the method further includes: obtaining the resource information required for the service to be processed according to the type of the service to be processed and the quantity of the service to be processed. In this way, the first network device does not need to obtain the resource information required for the service to be processed according to the type of the service to be processed and the quantity of the service to be processed, reducing the resource consumption of the first network device.

[0010] According to any one of the first aspect to the third possible implementation manner of the first aspect, in the fourth possible implementation manner, the determining, from one or more network devices other than the first network device according to the request message, the second network device includes: according to the request message, using a prediction model based on historical data, determining the second network device from one or more network devices, where the historical data includes the historical resource usage information of one or more network devices. In this way, the second network device determined by using the prediction model based on historical data refers to the past resource usage information of each network device, reducing the situation that the traffic volume of the second network device determined by the network controller itself increases, resulting in excessive resource consumption of the second network device.

[0011] According to any one of the first aspect to the fourth possible implementation manner of the first aspect, in the fifth possible implementation manner, the prediction model is used to predict the resource utilization trend of one or more network devices based on the historical resource usage information of one or more network devices. In this way, the second network device determined according to the resource utilization trend of one or more network devices can reduce the probability that the traffic volume of the second network device determined by the network controller increases in a very short future time period, resulting in excessive resource consumption of the second network device.

[0012] According to any one of the first aspect to the fifth possible implementation manner of the first aspect, in the sixth possible implementation manner, the determining, from one or more network devices other than the first network device according to the request message, the second network device includes: according to the request message and the available resource information of one or more network devices stored, determining the second network device from one or more network devices. In this way, determining the second network device according to the available resource information of one or more network devices currently stored can select the second network device whose current available resource information can meet the resource usage request of the first network device.

[0013] According to any one of the first aspect to the sixth possible implementation manners of the first aspect, in the seventh possible implementation manner, determining a second network device from one or more network devices other than the first network device according to the request message includes: determining a plurality of candidate network devices from a plurality of network devices other than the first network device according to the request message, and each of the plurality of candidate network devices has available resources capable of processing the service to be processed. Determining the second network device according to the network topology, where the second network device is a network device that meets the preset topology condition among the plurality of candidate network devices. In this way, the network controller can select, according to the topology structure of the network, a network device that is in the same local area network as the first network device, is under the same network device as the first network device, or meets the preset condition as the second network device. The first network device can conveniently send the service to be processed to the second network device for processing.

[0014] According to any one of the first aspect to the seventh possible implementation manners of the first aspect, in the eighth possible implementation manner, the method further includes: receiving resource usage information of one or more network devices sent by the one or more network devices, where the resource usage information includes available resource information, or the resource usage information includes used resource information. Determining the second network device from one or more network devices according to the request message includes: determining the second network device from the one or more network devices according to the request message and the resource usage information of the one or more network devices. In this way, the network controller can train a prediction model according to the resource usage information of one or more network devices sent by the received one or more network devices, or directly determine the second network device according to the resource usage information of one or more network devices sent by the received one or more network devices.

[0015] According to any one of the first aspect to the eighth possible implementation manners of the first aspect, in the ninth possible implementation manner, the method further includes: determining a third network device from one or more network devices according to the request message, where the third network device has second available resources capable of processing the service to be processed. Sending the first identification information of the second network device and the information of the first available resources, as well as the second identification information of the third network device and the information of the second available resources to the first network device. In this way, when any one of the one or more network devices cannot completely process the service to be processed, the network controller can determine two network devices to process the service to be processed of the first network device.

[0016] Second aspect, a resource allocation method is provided. This method is executed by a first network device, which is any network device connected to a network controller. The method includes: sending a request message to the network controller, where the request message is used to request available resources for a to-be-processed service request. Receiving first identification information of a second network device sent by the network controller, where the second network device has first available resources capable of processing the to-be-processed service. Among them, the to-be-processed service is any one of the other services described in the background art. Sending a first sub-service to the second network device according to the first identification information, where the first sub-service belongs to the to-be-processed service. In this way, the first network device can request available resources from the network controller and, according to the requested available resources, send the to-be-processed service to the network device providing the available resources for processing, which helps reduce the resource consumption of the first network device and improve the network usage experience of the user equipment connected to the first network device (i.e., improve the user experience).

[0017] According to the second aspect, in the first possible implementation manner of the second aspect, the request message includes resource information required for the to-be-processed service, and the resource information includes a resource type and a resource quantity. Alternatively, the request message includes the type of the to-be-processed service and the quantity of the to-be-processed service. Among them, the type of the to-be-processed service includes user identity verification, SAC, DPI, or AI big data analysis, etc. In this way, when the request message includes the type of the to-be-processed service and the quantity of the to-be-processed service, the first network device does not need to obtain the resource information required for the to-be-processed service according to the type of the to-be-processed service and the quantity of the to-be-processed service.

[0018] According to the second aspect or the first possible implementation manner of the second aspect, in the second possible implementation manner of the second aspect, when the request message includes the resource information required for the to-be-processed service, the resource type includes at least one of a computing resource type or a storage resource type.

[0019] According to any one of the second aspect to the second possible implementation manner of the second aspect, in the third possible implementation manner of the second aspect, the method further includes: obtaining information on the first available resources of the second network device from the network controller. The above-mentioned sending the first sub-service to the second network device according to the first identification information includes: sending the first sub-service to the second network device according to the information on the first available resources and the first identification information. In this way, the information on the first available resources represents the available resource information provided by the second network device for the first network device. The first network device sends the first sub-service that can be processed by the second network device to the second network device according to the available resource information, avoiding the situation where the quantity of the to-be-processed service sent by the first network device is too large and the second network device cannot process it or has too much processing pressure.

[0020] According to any one of the third possible implementation manners of the second aspect to the second aspect, in the fourth possible implementation manner of the second aspect, the method further includes: obtaining second identification information of a third network device from a network controller, where the third network device has second available resources capable of processing a to-be-processed service. According to the second identification information, sending a second sub-service to the third network device, where the second sub-service belongs to the to-be-processed service. In this way, the first network device can not only distribute the first sub-service in the to-be-processed service to the second network device for processing, but also send the second sub-service of the to-be-processed service to the third network device for processing. This avoids the situation where all to-be-processed services are sent to the same network device for processing, resulting in a significant increase in the resource consumption of this network device.

[0021] According to any one of the third possible implementation manners of the second aspect to the second aspect, in the fifth possible implementation manner of the second aspect, before sending a request message to the network controller, the method further includes: obtaining resource usage information of the first network device, where the resource usage information includes at least one of available resource information or used resource information. The above-mentioned sending a request message to the network controller includes: when the resource usage information of the first network device meets a condition, sending a request message to the network controller, where, if the resource usage information includes used resource information, the condition includes that the used resource value in the used resource information is greater than or equal to a first threshold, and if the resource usage information includes available resource information, the condition includes that the available resource value in the available resource information is less than or equal to a second threshold. In this way, when the first network device obtains that its current resource usage information meets a certain condition, that is, when the current available resources are insufficient, it can request available resources from the network controller, avoiding excessive resource consumption of the first network device.

[0022] According to any one of the third possible implementation manners of the second aspect to the second aspect, in the sixth possible implementation manner of the second aspect, the method further includes: receiving a third to-be-processed service sent by a fourth network device. Obtaining a processing result of the third to-be-processed service. Sending the processing result of the third to-be-processed service to the fourth network device and releasing the resources for processing the third to-be-processed service. In this way, when the first network device is relatively idle, it can also help process the third to-be-processed service of the fourth network device, thereby reducing the resource consumption of the fourth network device.

[0023] In a third aspect, a network controller is provided, and the network controller can be used to execute any one of the methods provided in any one of the possible implementation manners of the first aspect to the first aspect.

[0050] All the services to be processed mentioned in the present application refer to other services.

[0051] Before introducing the resource allocation method provided by the embodiments of the present application in detail, the application scenarios and implementation environments involved in the embodiments of the present application are briefly introduced here.

[0052] The network in the embodiments of the present application can be a campus network. A campus network generally refers to the campus network of a university and the internal network of an enterprise. The main feature of a campus network is that the routing structure is completely managed by an institution. The network mentioned in the embodiments of the present application is not limited to the campus network. The application scenario of the embodiments of the present application includes that when there are too many basic telecommunications services on the first network device in the network and other services are enabled, the problem of excessive resource consumption of the first network device will occur. Among them, the first network device is any network device connected to the network controller. In this way, it will affect the basic telecommunications services such as the access of normal user equipment or packet forwarding of the first network device, and further affect the network usage of the user equipment accessing the first network device.

[0053] In the embodiment of the present application, the network controller receives a request message from a first network device, and determines, according to the available resources requested in the request message, a second network device that can provide the first available resources capable of processing the to-be-processed service of the first network device for the first network device. In this way, the network controller can send the first identification information of the second network device to the first network device, thereby instructing the first network device to transfer the to-be-processed service of the first network device to the second network device for processing. This helps to reduce the resource consumption of the first network device and improve the user's network usage experience. At the same time, the idle resources of the second network device can be utilized, improving the resource utilization efficiency.

[0054] As Figure 1 shown, it is a schematic diagram of the network architecture applicable to the embodiment of the present application. Figure 1 The network architecture shown may include a network controller 101 and multiple network devices 102. Figure 1 In the following, two network devices 102 are taken as an example for illustration. Among them, the network controller 101 is connected to each network device 102 through a network. The embodiment of the present application does not limit the connection manner between the network controller 101 and the network device 102. In one possible implementation manner, the network controller 101 is directly connected to the network device 102. In another possible implementation manner, the network controller 101 is indirectly connected to the network device 102.

[0055] The network controller 101 is responsible for the registration of the network devices 102 in the network, the collection of the available resources of each network device 102, the trend prediction of the resource usage information of each network device 102, and the centralized scheduling of the resources in the network device 102, etc.

[0056] The network device 102 feeds back resource usage information to the network controller 101 and responds to the scheduling of the network controller 101.

[0057] It should be noted that Figure 1 the network structures of the network controller 101 and the network device 102 shown in the actual network can be Figure 2 the network structures shown. As Figure 2 shown in the schematic diagram of the network structure applicable to the embodiment of the present application, the network device 102 can be any one of a wireless access point (AP), a wireless access controller (WAC), a core switch, an aggregation switch, an access switch, etc. Among them, the "core switch and WAC" are directly connected to the network controller 101, and the aggregation switch, the access switch, and the wireless access point are indirectly connected to the network controller 101.

[0061] The communication interface 304 uses any device such as a transceiver to communicate with other devices or communication networks, such as a wide area network (WAN), a local area network (LAN), etc.

[0062] The memory 303 can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 303 can exist independently and be connected to the processor 301 through the communication line 302. The memory 303 can also be integrated with the processor 301. The memory 303 provided in the embodiments of the present application generally can have non-volatility. Among them, the memory 303 is used to store computer instructions for executing the solution of the present application and is controlled by the processor 301 to execute.

For example, the input device 306 may be a mouse, a keyboard, a touch screen device, or a sensing device, etc.

[0066] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0067] The technical solutions provided by the embodiments of the present application include: an initialization phase and a resource allocation phase. Hereinafter, these two phases will be described separately:

[0068] Initialization phase

[0069] As Figure 4 shown is a schematic flowchart of the initialization phase of a resource allocation method provided by an embodiment of the present application. Exemplarily, this embodiment can be applied to Figure 1 the network architecture shown, that is, the following network device may be network device 102, and the network controller may be network controller 101. Figure 4 The method shown may include the following steps:

[0070] S100: The network device sends a registration message to the network controller. Among them, the network device is any network device connected to the network controller. The registration message may include the total resource information of the network device.

[0071] It should be noted that after the network device is powered on, each network device that establishes a connection with the network controller can send a registration message to the network controller, or a registration message is carried in the request message for establishing a connection sent by the network device to the network controller. This registration message is used to inform the network controller that the resources of the network device sending the registration message can be shared with other network devices in the network.

[0072] When the registration message includes the total resource information of the network device, for example, the total resource information of the network device may include: the computing power of the network device's processor is 800MHZ×3700, the memory of the network device is 5G, the flash storage space of the network device is 5G, and the total bandwidth of the network device is 1000Mbps.

[0073] S101: The network device sends resource usage information to the network controller.

[0074] The network device that has sent the registration message can periodically send resource usage information to the network controller. Among them, the resource usage information includes available resource information, or the resource usage information includes used resource information. The resource allocation method provided by the embodiments of the present application is not affected by the triggering conditions for the network device to send resource usage information to the network controller. Therefore, the network device can actively send resource usage information to the network controller, or can also send resource usage information to the network controller after receiving a request message from the network controller requesting to obtain resource usage information.

[0075] When the resource usage information of the network device includes available resource information, for example, the available resource information of the network device includes: the available computing power of the network device's processor is 800MHZ×3700×70%, the remaining memory of the network device is 5G×75%, the remaining flash storage space of the network device is 5G×60%, and the remaining bandwidth of the network device is 600Mbps. As another example, since the network controller may have obtained the total resource information of the network device during the registration phase, the available resource information sent by the network device can also be the resource occupancy ratio, rather than the specific value of the available resource. For example, the available resource information sent by the network device to the network controller can be that the available computing power of the processor is 70%, the remaining memory of the network device is 75%, the remaining flash storage space of the network device is 60%, and the remaining bandwidth of the network device is 60%.

[0076] Figure 4 The above is described by taking one network device as an example. It can be understood that all network devices that can share resources with other network devices and are connected to the network controller can execute S100~S101. It can also be understood that the above S100 may not be executed, and S101 can be directly executed.

[0077] S102: The network controller stores the available resource information of each network device according to the received resource usage information of each network device, or the network controller can train a prediction model according to the received resource usage information of each network device in different historical periods.

[0078] In one case, when the resource usage information sent by a network device includes available resource information, the network device stores the available resource information of each network device.

[0079] In another case, when the resource usage information sent by a network device includes used resource information, the network device obtains and stores the available resource information of each network device according to the used resource information and the total resource information.

[0080] The network controller can train a prediction model according to the resource usage information of each network device in different historical periods received. Among them, the prediction model can be used to predict the resource utilization trend of one or more network devices based on the historical resource usage information of the one or more network devices, and obtain the resource list of each network device. The embodiments of the present application do not uniquely limit the method for the prediction model to predict the resource utilization trend of one or more network devices based on the historical resource usage information of the one or more network devices. Exemplarily, the prediction model uses algorithms such as Gaussian regression algorithm or neural network algorithm, based on the historical resource usage information of one or more network devices, predicts the resource utilization trend of the one or more network devices, and determines the network devices that can provide corresponding resources during the corresponding time periods when resources are needed according to the resource utilization trend of the one or more network devices.

[0081] Resource allocation phase

[0082] The following takes the perspective of the first network device as the resource requester and the second network device as the resource provider as an example to illustrate the resource allocation method provided by the embodiments of the present application. As Figure 5 shown is a schematic flowchart of the resource allocation phase of a resource allocation method provided by the embodiments of the present application. Exemplarily, this embodiment can be applied to Figure 1 the network architecture shown. Figure 5 The method shown may include the following steps:

[0083] S200: The first network device sends a request message to the network controller. The request message is used to request available resources for the service to be processed. Among them, the service to be processed may include services such as user identity verification, SAC, DPI, or AI big data analysis.

[0084] Optionally, the request message includes the resource information required for the service to be processed. The resource information includes the resource type and the resource quantity; or, the request message includes the type of the service to be processed and the quantity of the service to be processed. When the request message includes the resource information required for the service to be processed, the resource type includes at least one of the computing resource type or the storage resource type.

[0085] Exemplarily, the computing resource type includes a processor, and the storage resource type includes memory and external storage (such as flash storage space, cache, etc.). The resource information may include the computing power of the processor, the memory size, the bandwidth size, and the external storage size, etc.

[0086] Optionally, the first network device obtains the resource usage information of the first network device, and the resource usage information includes at least one of available resource information or used resource information. When the resource usage information of the first network device meets the condition, a request message is sent to the network controller. Among them, if the resource usage information includes used resource information, the condition includes that the used resource value in the used resource information is greater than or equal to a first threshold, and if the resource usage information includes available resource information, the condition includes that the available resource value in the available resource information is less than or equal to a second threshold.

[0087] Exemplarily, when the resource usage information includes used resource information, the condition may include at least one of the processor utilization rate of the first network device being greater than or equal to 80%, the memory utilization rate of the first network device being greater than or equal to 85%, the flash storage space utilization rate of the first network device being greater than or equal to 75%, and the bandwidth utilization rate of the first network device being greater than or equal to 90%.

[0088] S201: The network controller determines a second network device from one or more network devices other than the first network device according to the request message, and the second network device has the first available resources capable of processing the service to be processed.

[0089] When the request message includes the resource information required for the service to be processed:

[0090] According to different possible situations, the network controller can determine the second network device from one or more network devices other than the first network device according to the required resource information in the following different ways:

[0091] Method 1: When the network controller stores a prediction model based on historical data, the network controller determines the second network device from one or more network devices according to the required resource information, using the prediction model based on historical data. The second network device is the network device that can provide the resources indicated by the required resource information according to the prediction model. Among them, the historical data includes the historical resource usage information of one or more network devices.

[0092] Exemplarily, for instance, the network controller can obtain the historical resource usage of network device A in the past week and the historical resource usage of network device B during the same period. The network controller can analyze the resource utilization trends of network device A and network device B based on the obtained historical resource usages of network device A and network device B respectively, using prediction models such as the Gaussian regression algorithm or the neural network algorithm. If network device C sends a resource request message requesting the available resources from 12:00 am to 1:00 pm on the current day, the network controller can determine the network device that can provide the available resources according to the prediction result of the resource utilization trend. Specifically, for example, when the network controller receives the request message from network device C, the resource information requested in the request message includes a processor computing power of 800 MHz × 3700 × 20%. Through prediction, it is known that the processor computing power of network device A is approximately 800 MHz × 3700 × 10% from 12:00 am to 1:00 pm, and the processor computing power of network device B is approximately 800 MHz × 3700 × 80% from 12:00 am to 1:00 pm. Thus, it can be seen that network device A cannot meet the resources requested by network device C, while network device B can meet the resources requested by network device C. Therefore, the network controller determines network device B as the second network device and can send the identification information of network device B to network device C.

[0093] In this way, the second network device determined according to the resource utilization trend of the network device can reduce the probability that the determined second network device has an increase in traffic volume in a very short future time period, resulting in excessive resource consumption of the second network device.

[0094] Method 2: When the network controller stores the available resource information of each network device, the network controller determines the second network device from one or more network devices according to the required resource information and the stored available resource information of one or more network devices.

[0095] Exemplarily, the current available resource information of network device A is: the processor computing power is 800 MHz × 3700 × 10%, and the available resource information of network device B is: the processor computing power is 800 MHz × 3700 × 80%. The network controller receives the request message from network device C, and the resource information requested in the request message includes a processor computing power of 800 MHz × 3700 × 20%. The current processor computing power of network device A is less than the processor computing power requested by network device C, and the current processor computing power of network device B is greater than the processor computing power requested by network device C. Then, based on the resource usage information of network device A and network device B, the network controller will determine network device B as the second network device.

[0096] In some cases, the network controller may determine multiple network devices, including the second network device, as the network devices for processing the pending service of the first network device. That is, based on the required resource information, in addition to determining the second network device, the network controller may also determine one or more other network devices from one or more network devices as resource providers. For example, when the second network device has a first available resource capable of processing the pending service and the third network device has a second available resource capable of processing the pending service, the network controller may select both the second network device and the third network device as the network devices providing available resources to the first network device.

[0097] The network controller may determine the second network device and the third network device from one or more network devices according to the required resource information and the available resource information of one or more stored network devices; the network controller may also use a prediction model based on historical data to determine the second network device and the third network device.

[0098] When the available resource information of each currently known network device cannot satisfy the requirement of processing the pending service of the first network device alone, the network controller may determine multiple network devices as resource providers for the pending service at the same time. That is, in addition to determining the second network device for processing the first sub-service of the pending service, the network controller also determines the third network device for processing the second sub-service of the pending service.

[0099] It can be understood that the pending service of the first network device can be divided into multiple sub-services, and each sub-service may correspond to a processing result. For example, the pending service of the first network device is the authentication of 100 user identities. Then, the first sub-service may be the authentication of 40 user identities, and the second sub-service may be the authentication of 60 user identities. In this case, the processing results of the first sub-service and the second sub-service are relatively independent. It can be understood that in other possible cases, the processing results of the first sub-service and the second sub-service may also be somewhat related. For example, the first network device may continue to perform subsequent processing based on the processing results of the first sub-service and the second sub-service after the processing results of the first sub-service and the second sub-service are respectively returned.

[0100] Exemplarily, the current available resource information of network device A is: the processor computing power is 800 MHZ × 3700 × 10%, and the available resource information of network device B is: the processor computing power is 800 MHZ × 3700 × 80%. The network controller receives a request message from network device C, and the resource information requested by the request message includes a processor computing power of 800 MHZ × 3700 × 85%. In this way, the processor computing power of each of network device A and network device B cannot meet the processor computing power requested by the request message of network device C. The network controller can determine that network device A provides a processor computing power of 800 MHZ × 3700 × 5%, and network device B provides a processor computing power of 800 MHZ × 3700 × 80%.

[0101] In other possible scenarios, even when the network controller determines that the available resources of at least one network device can meet the pending service of the first network device alone, the network controller can still determine to use multiple network devices to jointly complete the pending service of the first network device. For example, it is determined that the second network device is used to process the first sub-service of the pending service, and the third network device is used to process the second sub-service of the pending service. In this way, it is possible to avoid excessive resource consumption of the second network device after the first network device sends the pending service to the second network device for processing.

[0102] When determining the network device for processing the pending service of the first network device, the network controller can also refer to the network topology relationship to determine the final network device for processing the pending service. For example, the network controller determines multiple candidate network devices from multiple network devices according to the required resource information, and all of these multiple candidate network devices have available resources capable of processing the pending service. At this time, the network controller determines the second network device according to the network topology, and the second network device is a network device that meets the preset topology conditions among the multiple candidate network devices. Among them, the preset topology conditions may include that the first network device and the second network device are mounted under a network device, the first network device and the second network device are in the same local area network, or the length of the topology path between the first network device and the second network device is less than a threshold, etc. The network controller stores the topology paths between each network device in the network.

[0103] Among them, the network controller determines multiple candidate network devices from multiple network devices according to the available resource information of one or more network devices stored, or the network controller determines multiple candidate network devices from multiple network devices by using a prediction model based on historical data. The resources of each candidate network device among the multiple candidate network devices determined by the network controller can satisfy the to-be-processed service of the first network device, or multiple network devices among the multiple candidate network devices determined by the network controller are all required to be used to process the to-be-processed service of the first network device. The embodiments of the present application do not make a unique limitation on this.

[0104] Exemplarily, the current available resource information of network device A is: the processor computing power is 800MHZ×3700×50%, and the resource usage information of network device B is: the processor computing power is 800MHZ×3700×80%. The network controller receives a request message from network device C, and the resource information requested in the request message includes a processor computing power of 800MHZ×3700×20%. In this way, the respective processor computing powers of network device A and network device B can satisfy the processor computing power requested in the request message of network device C. At this time, network device A and network device C are both connected to network device D and can communicate with each other through network device D, then the network controller determines that network device A provides available resources for network device C.

[0105] When the request message includes the type of the to-be-processed service and the quantity of the to-be-processed service, wherein, the type of the to-be-processed service includes user identity verification, SAC, DPI or AI big data analysis, etc. For example, when the type of the to-be-processed service is user identity verification, the quantity of the to-be-processed service is the number of user identities to be verified, and when the type of the to-be-processed service is SAC, DPI or AI big data analysis, the quantity of the to-be-processed service can be the number of packets forwarded by the network device.

[0106] First, the network controller obtains the resource information required for the to-be-processed service according to the type of the to-be-processed service and the quantity of the to-be-processed service.

[0107] The corresponding relationship between the "type of the to-be-processed service and the quantity of the to-be-processed service" and the "resource information required for the to-be-processed service" can be pre-stored in the network controller, or this corresponding relationship can be pre-stored in any network device connected to the network controller. The network controller can obtain the "resource information required for the to-be-processed service" corresponding to the "type of the to-be-processed service and the quantity of the to-be-processed service" according to this corresponding relationship.

[0108] Exemplarily, assume that the "type of business to be processed" in the request message is user authentication, and the number of businesses to be processed is 100. The pre-stored correspondence between the "type of business to be processed and the number of businesses to be processed" and the "resource information required for the business to be processed" is that one user authentication requires a processor computing power of 800 MHZ × 3700 × 0.05%, and the required device memory size is 1 M. According to this correspondence, the computing power required for this request message is 800 MHZ × 3700 × 0.05% × 100, and the required device memory size is 1 M × 100.

[0109] Secondly, the network controller determines a second network device from one or more network devices according to the required resource information. Specifically, referring to the above various possible implementation manners, it will not be elaborated here.

[0110] S202: The network controller sends the first identification information of the second network device to the first network device.

[0111] In one case, when the network controller determines that the second network device can provide all the required resource information requested by the first network device, the network controller sends the first identification information of the second network device to the first network device. Alternatively, the network controller sends the first identification information of the second network device and the available resource information of the second network device to the first network device.

[0112] In another case, when the network controller determines that the second network device can provide the first available resource information and the third network device can provide the second available resource information, the network controller sends the first identification information of the second network device and the information of the first available resource, as well as the second identification information of the third network device and the information of the second available resource, to the first network device.

[0113] It can be understood that the first identification information may be the Internet Protocol (IP) address of the second network device, or the Media Access Control (MAC) address of the second network device, or a device identifier that can be recognized by each network device within a certain network range, or any other possible identifier type, etc., as long as the first network device can determine the second network device that can receive the business to be processed according to the identification information after receiving the identification information sent by the network controller.

[0114] Subsequently, when the first network device only receives the first identification information of the second network device, the first network device sends the business to be processed to the second network device. After the second network device processes the business to be processed, the first network device receives the processing result sent by the second network device.

[0115] When the first network device receives the first identification information of the second network device and the information of the first available resources, as well as the second identification information of the third network device and the information of the second available resources, the first network device divides the service to be processed into a first sub-service and a second sub-service according to the information of the first available resources and the information of the second available resources. Among them, the first available resources are used to process the first sub-service, and the second available resources are used to process the second sub-service. The first network device sends the first sub-service to the second network device and sends the second sub-service to the third network device. After that, the first network device respectively receives the first processing result of the first sub-service sent by the second network device and the second processing result of the second sub-service sent by the third network device. It can be understood that the first network device can, according to actual service needs, only save after receiving one or more of the first processing result and the second processing result; or, it can also continue with subsequent service processing after receiving one or more of the first processing result and the second processing result.

[0116] In the embodiments of the present application, the network controller determines, according to the request message sent by the first network device, a second network device that can provide available resources for processing the service to be processed by the first network device. In this way, on the one hand, the first network device can send the service to be processed to the second network device for processing, thereby reducing the resource consumption of the first network device and improving the network usage experience of the user equipment accessing the first network device. On the other hand, due to the resource scheduling of the network controller, the idle resources of the second network device are utilized, and the resource utilization efficiency within the network is improved.

[0117] The following takes the fourth network device as the resource requester and the first network device as the resource provider as an example to illustrate the resource allocation method provided by the embodiments of the present application, as Figure 6 shown in the flowchart of the resource allocation phase of another resource allocation method provided by the embodiments of the present application. Exemplarily, this embodiment can be applied to Figure 1 the network architecture shown. The situation described by this method can be, for example, before the first network device still has a certain amount of available resources and thus does not need to execute the Figure 5 method shown, or it can also be when the first network device has available resources that can be used by other network devices after releasing its own resources after completing one or more services using the resources of other network devices. Figure 6 The method shown can include the following steps:

[0118] S300 - S302: Specifically refer to the execution steps in S200 - S202, replace the first network device with the fourth network device, and replace the second network device with the first network device, which will not be elaborated here.

[0119] S303: The fourth network device sends a second pending service to the first network device according to the received identification information of the first network device. Here, the second pending service is the pending service in the fourth network device. The second pending service includes services such as user identity verification, SAC, DPI, or AI big data analysis. In one case, when the fourth network device receives the third identification information of the first network device sent by the network controller, the fourth network device sends the second pending service to the first network device.

[0120] In another case, when the fourth network device receives the third identification information of the first network device and the information of the third available resources, the fourth network device sends a third sub-service to the first network device according to the third identification information of the first network device and the information of the third available resources. Here, the third sub-service belongs to the second pending service. The third available resources can be used to process the third sub-service.

[0121] It should be noted that the pending services of the fourth network device can be divided into multiple sub-services, and each sub-service has a corresponding processing result. For example, the pending service of the first network device is the verification of 100 user identities. Then, the third sub-service can be the verification of 40 user identities, and the fourth sub-service can be the verification of 60 user identities.

[0122] S304: The first network device obtains the processing result of the second pending service.

[0123] Exemplarily, the first network device receives the service of verifying 100 user identities sent by the fourth network device. The first network device obtains the verification results of the 100 user identities.

[0124] S305: The first network device sends the processing result to the fourth network device.

[0125] Based on the example in S304, the first network device sends the verification results of the 100 user identities to the fourth network device.

[0126] S306: The first network device releases the resources used to process the second pending service.

[0127] Subsequently, after the first network device releases the resources, it can obtain its own resource usage information and send the latest resource usage information to the network controller. This resource usage information is used by the network controller to update and maintain the available resource information of the first network device.

[0128] In the embodiments of the present application, the network controller determines, according to a request message sent by a fourth network device, a first network device that can provide available resources for processing the service to be processed by the fourth network device. In this way, on the one hand, the fourth network device can send the service to be processed to the first network device for processing, thereby reducing the resource consumption of the fourth network device and improving the network experience of the user equipment accessing the fourth network device. On the other hand, due to the scheduling of resources by the network controller, the idle resources of the first network device are utilized, improving the resource utilization efficiency within the network.

[0129] Combined with the above Figure 5 and Figure 6 As can be seen from the illustrated embodiments, the same network device can send its own service to be processed to other network devices that can provide processing resources for processing, and can also process the services to be processed sent by other network devices when the available resources of the network device are relatively large. Thus, the problem that the resource utilization in the network is unbalanced, resulting in excessive resource consumption of individual network devices and affecting the network usage of the user equipment accessing the network device, is effectively solved. At the same time, the idle resources in the network can be utilized to improve the resource utilization efficiency within the network.

[0130] It can be understood that the order of the execution steps in the above method embodiments is only a possible example. In actual applications, the execution order of the steps can be adjusted as needed.

[0131] The above mainly introduces the solution provided by the embodiments of the present application from the perspective of methods. To implement the above functions, it includes the corresponding hardware structures and / or software modules for executing each function.

Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0132] The embodiments of the present application can divide the network device and the network controller into functional modules according to the above method examples. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiments of the present application is illustrative, only a logical function division, and there may be other division methods in actual implementation.
