Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and apparatus.

Background

Currently, services supported by network devices (such as an access switch, a convergence switch, a wireless local area network access point (WLAN AP) or a Wireless Access Controller (WAC)) in a communication network include basic telecommunication services and other services. Wherein, the basic telecommunication service comprises: access of user equipment or message forwarding, etc. Other services include user identity verification, intelligent application control (SAC), Deep Packet Inspection (DPI), or Artificial Intelligence (AI) big data analysis.

Meanwhile, idle resources of the second network equipment can be utilized, and the resource utilization efficiency is improved. It can be understood that, when there are more basic telecommunication services of the first network device, the pending service of the first network device (i.e. other services described in the background) may cause the resource consumption of the first network device to be too high, and at this time, the first network device may request the resource from the network controller and send the pending service to the second network device capable of providing the resource for processing, so as to reduce the resource consumption of the first network device and improve the network usage experience of the user equipment accessing the first network device.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

The technical scheme provided by the embodiment of the application comprises the following steps: an initialization phase and a resource allocation phase. These two stages are explained below:

initialization phase

Fig. 4 is a schematic flowchart of an initialization phase of a resource allocation method according to an embodiment of the present application. For example, the present embodiment may be applied to the network architecture shown in fig. 1, that is, the network device described below may be the network device 102, and the network controller may be the network controller 101. The method shown in fig. 4 may comprise the steps of:

s100: the network device sends a registration message to the network controller. The network device is any one of the network devices connected with the network controller. The registration message may include total resource information for the network device.

It should be noted that, after the network device is powered on, each network device that establishes a connection with the network controller may send a registration message to the network controller, or a request message for establishing a connection that is sent by the network device to the network controller carries the registration message, where the registration message is used to inform the network controller that resources of the network device that sends the registration message may be shared with other network devices in the network.

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 capacity of a processor of the network equipment is 800MHZ x 3700, the memory of the network equipment is 5G, the flash storage space of the network equipment is 5G, and the total bandwidth of the network equipment is 1000 Mbps.

S101: the network device sends resource usage information to the network controller.

The network device that sent the registration message may periodically send resource usage information to the network controller. Wherein the resource usage information includes available resource information, or the resource usage information includes used resource information. The resource allocation method provided by the embodiment of the application is not influenced by the trigger condition that the network equipment sends the resource use information to the network controller. Therefore, the network device may actively send the resource usage information to the network controller, or may send the resource usage information to the network controller after receiving a request message sent by the network controller to request to obtain the resource usage information.

When the resource usage information of the network device includes available resource information, the available resource information of the network device illustratively includes: the available computing power of the processor of the network device is 800MHZ x 3700 x 70%, the remaining memory of the network device is 5G x 75%, the remaining flash storage space of the network device is 5G x 60%, and the remaining bandwidth of the network device is 600 Mbps. As another example, since the network controller may have already obtained the total resource information of the network device in the registration phase, the available resource information sent by the network device may also be a resource occupancy ratio, instead of a specific value of the available resource, for example, the available resource information sent by the network device to the network controller may be 70% of the available computing capacity of the processor, 75% of the remaining memory of the network device, 60% of the remaining flash storage space of the network device, and 60% of the remaining bandwidth of the network device.

Fig. 4 illustrates one network device as an example, and it is understood that all network devices that can share resources with other network devices and are connected to the network controller may perform S100 to S101. It is also understood that S100 may not be executed, and S101 is directly executed.

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 may train the prediction model according to the received resource usage information of each network device in different historical periods.

In one case, when the resource usage information transmitted by the network device includes available resource information, the network device stores the available resource information of the respective network devices.

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

The network controller may train the predictive model based on the received resource usage information for each network device over different historical periods. The prediction model may be configured to predict a resource utilization trend of one or more network devices based on historical resource usage information of the one or more network devices, and obtain a resource list of each network device. The method for predicting the resource utilization rate trend of one or more network devices by the prediction model based on the historical resource utilization information of the one or more network devices is not limited uniquely. For example, the prediction model predicts a resource utilization trend of one or more network devices based on historical resource utilization information of the one or more network devices using a gaussian regression algorithm, a neural network algorithm, or the like, and determines network devices that can provide corresponding resources at corresponding time periods when the resources are needed according to the resource utilization trend of the one or more network devices.

Resource allocation phase

The following describes the resource allocation method provided in the embodiment of the present application with an angle that the first network device is a resource requester and the second network device is a resource provider as an example, and fig. 5 is a schematic flow diagram of a resource allocation stage of the resource allocation method provided in the embodiment of the present application. Illustratively, the present embodiment may be applied to the network architecture shown in fig. 1. The method shown in fig. 5 may comprise the steps of:

s200: the first network device sends a request message to the network controller, the request message being used to request available resources for the pending service. The service to be processed may include authentication of user identity, SAC, DPI, or AI big data analysis, and other types of services.

Optionally, the request message includes resource information required by the service to be processed, where the resource information includes a resource type and a resource quantity; or, the request message includes the type of the service to be processed and the number of the service to be processed. When the request message includes resource information required by the service to be processed, the resource type includes at least one of a computing resource type or a storage resource type.

Illustratively, the computing resource type includes a processor, and the storage resource type includes a memory, an external memory (e.g., a flash memory space, a cache, etc.). The resource information may include the size of the computing power of the processor, the size of the memory, the size of the bandwidth, the size of the external memory, and the like.

Optionally, the first network device obtains 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. When the resource usage information of the first network device satisfies a condition, a request message is sent to a network controller. If the resource usage information includes used resource information, the condition includes that a used resource value in the used resource information is greater than or equal to a first threshold value, and if the resource usage information includes available resource information, the condition includes that an available resource value in the available resource information is less than or equal to a second threshold value.

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

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, the second network device having a first available resource capable of processing the pending traffic.

When the request message comprises the resource information required by the service to be processed:

according to different possible situations, the network controller may determine the second network device from one or more network devices other than the first network device according to the required resource information in different ways as follows:

the first method is as follows: when the network controller stores a prediction model based on the historical data, the network controller determines a second network device from the one or more network devices according to the required resource information by using the prediction model based on the historical data, wherein the second network device is the network device which can provide the resource indicated by the required resource information and is determined according to the prediction model. Wherein the historical data includes historical resource usage information for the one or more network devices.

Illustratively, the network controller may obtain historical resource usage for network device a over the past week, and obtain historical resource usage for network device B on the same time segment, for example. The network controller may analyze resource utilization trends of the network device a and the network device B by using prediction models such as a gaussian regression algorithm or a neural network algorithm based on the acquired historical resource usage of each of the network device a and the network device B. If network device C sends a resource request message requesting available resources from 12 am to 1 pm of the day, the network controller may determine a network device capable of providing the available resources based on the prediction of the resource utilization trend. Specifically, for example, the network controller receives the request message from network device C, the resource information requested by the request message includes a processor computing power of 800MHZ × 3700 × 20%, whereas it is predicted that the processor computing power of network device a is about 800MHZ × 3700 × 10% from 12 am to 1 pm, and the processor computing power of network device B is about 800MHZ × 3700 × 80% from 12 am to 1 pm. It is thus known that network device a cannot satisfy the resource requested by network device C, and that network device B can satisfy the resource requested by network device C. Thus, the network controller determines network device B as the second network device, and may transmit the identification information of network device B to network device C.

In this way, the second network device determined according to the trend of the resource utilization rate of the network device can reduce the probability that the determined second network device has increased traffic in a short future time period, thereby causing excessive resource consumption of the second network device.

The second method comprises the following steps: when the network controller stores available resource information of each network device, the network controller determines a second network device from the one or more network devices according to the required resource information and the stored available resource information of the one or more network devices.

Illustratively, the current available resource information of the network device a is: the computing power of the processor is 800MHZ x 3700 x 10%, and the available resource information of the network device B is: the processor computing power is 800MHZ x 3700 x 80%. The network controller receives a request message from network device C, the resource information requested by the request message includes the processor computing capacity of 800MHZ × 3700 × 20%. Network device a has a current processor computing power less than the processor computing power requested by network device C, and network device B has a current processor computing power greater than the processor computing power requested by network device C. Then the network controller may determine network device B as the second network device based on the resource usage information for network device a and network device B.

In some cases, the network controller may determine a plurality of network devices, including the second network device, as the network device that handles pending traffic for the first network device. That is, the network controller may determine, in addition to the second network device, other one or more network devices from among the one or more network devices as the resource provider according to the required resource information. For example, when the second network device has a first available resource capable of processing the pending traffic and the third network device has a second available resource capable of processing the pending traffic, the network controller may select the second network device and the third network device together as the network device providing the available resources to the first network device.

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

When the network controller cannot independently process the service to be processed of the first network device according to the currently known available resource information of each network device, it may be determined that the plurality of network devices are simultaneously used as resource providers of the service to be processed. That is, the network controller determines that the third network device is used for processing the second sub-service of the pending service, in addition to determining that the second network device is used for processing the first sub-service of the pending service.

It can be understood that the to-be-processed service of the first network device may be divided into a plurality of sub-services, and each sub-service may correspond to one processing result. For example, the pending service of the first network device is the verification of 100 user identities. Then, the first sub-service may be 40 user identities and the second sub-service may be 60 user identities, in which case the processing results of the first sub-service and the second sub-service are relatively independent. It is to be understood that, in other possible cases, the processing results of the first sub-service and the second sub-service may also be in a certain relationship, 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 returned respectively, and the like.

Illustratively, the current available resource information of the network device a is: the computing power of the processor is 800MHZ x 3700 x 10%, and the available resource information of the network device B is: the processor computing power is 800MHZ x 3700 x 80%. The network controller receives a request message from network device C, the resource information requested by the request message includes the processor computing capacity of 800MHZ × 3700 × 85%. Thus, the respective processor computing capabilities of network device a and network device B may not satisfy the processor computing capabilities requested by the request message of network device C. The network controller may determine that network device a provides 800MHZ x 3700 x 5% of the processor computing power. Network device B provides a processor computing power of 800MHZ x 3700 x 80%.

In other possible cases, even if the network controller determines that at least one available resource of the network device is sufficient to process the pending service of the first network device alone, the network controller may still determine that the pending service of the first network device is completed by using multiple network devices together, for example, determine that a second network device is used for processing a first sub-service of the pending service, and determine that a third network device is used for processing a second sub-service of the pending service. Therefore, the resource consumption of the second network equipment can be avoided from being too large after the first network equipment sends the service to be processed to the second network equipment for processing.

When determining the network device for processing the service to be processed of the first network device, the network controller may further refer to the network topology relationship to determine the network device finally used for processing the service to be processed. For example, the network controller determines a plurality of candidate network devices from the plurality of network devices according to the required resource information, the plurality of candidate network devices each having available resources capable of processing the pending traffic. At this time, the network controller determines a second network device according to the network topology, where the second network device is a network device that meets a preset topology condition among the plurality of candidate network devices. The preset topology condition may include that the first network device and the second network device are mounted under one network device, the first network device and the second network device are in the same local area network, or the length of a topology path between the first network device and the second network device is smaller than a threshold, and the like. The network controller stores topology paths between network devices in the network.

The network controller determines a plurality of candidate network devices from the plurality of network devices according to the stored available resource information of the one or more network devices, or determines the plurality of candidate network devices from the plurality of network devices by using a prediction model based on historical data. The resource of each candidate network device in the plurality of candidate network devices determined by the network controller satisfies processing of the service to be processed of the first network device, or the plurality of candidate network devices determined by the network controller all need to be used for processing of the service to be processed of the first network device. The embodiments of the present application are not limited to this.

Illustratively, the current available resource information of the network device a is: the computing power of the processor is 800MHZ x 3700 x 50%, and the resource use information of the network device B is as follows: the processor computing power is 800MHZ x 3700 x 80%. The network controller receives a request message from network device C, the resource information requested by the request message includes the processor computing capacity of 800MHZ × 3700 × 20%. In this way, the respective processor computing capabilities of network device a and network device B may satisfy the processor computing capabilities requested by the request message of network device C. At this time, the network device a and the network device C are connected to the network device D at the same time, and can perform mutual communication through the network device D, and then the network controller determines that the network device a provides available resources for the network device C.

When the request message includes the type of the service to be processed and the number of the service to be processed, wherein the type of the service to be processed includes user identity verification, SAC, DPI or AI big data analysis, and the like. For example, when the type of the service to be processed is the authentication of the user identity, the number of the service to be processed is the number of the user identity to be authenticated, and when the type of the service to be processed is the SAC, DPI, or AI big data analysis, the number of the service to be processed may be the number of the packets forwarded by the network device.

Firstly, the network controller obtains the resource information required by the service to be processed according to the type of the service to be processed and the number of the service to be processed.

The network controller may pre-store a correspondence between the "type of service to be processed and the number of services to be processed" and the "resource information required by the service to be processed", or the correspondence may be pre-stored in any one of the network devices connected to the network controller. The network controller may obtain "the resource information required by the service to be processed" corresponding to the "type of the service to be processed and the number of the service to be processed" according to the correspondence.

For example, it is assumed that the "type of pending service" in the request message is user authentication, and the number of pending services is 100. The pre-stored correspondence between the type of the service to be processed and the number of the service to be processed and the resource information required by the service to be processed is that the calculation capacity of a processor required for user identity authentication is 800MHZ x 3700 x 0.05%, and the size of the memory required for equipment is 1M. The computing power required for the request message according to the correspondence is 800MHZ × 3700 × 0.05% × 100, and the required device memory size is 1M × 100.

Second, the network controller determines a second network device from the one or more network devices based on the required resource information. Specifically, reference is made to the above various possible implementation manners, which are not described in detail.

S202: the network controller sends first identification information of the second network device to the first network device.

In one case, when the network controller determines that the second network device is capable of providing all of the required resource information requested by the first network device, the network controller sends first identification information of the second network device to the first network device. Or, 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.

In another case, when the network controller determines that the second network device is capable of providing the first available resource information and the third network device is capable of providing the second available resource information, the network controller transmits the first identification information of the second network device and the information of the first available resource, and the second identification information of the third network device and the information of the second available resource to the first network device.

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

Subsequently, when the first network device only receives the first identification information of the second network device, the first network device sends the service to be processed to the second network device, and after the second network device finishes processing the service to be processed, the first network device receives the processing result sent by the second network device.

When the first network device receives the first identification information and the first available resource information of the second network device, and the second identification information and the second available resource information of the third network device, the first network device divides the service to be processed into a first sub-service and a second sub-service according to the first available resource information and the second available resource information. Wherein the first available resource is used for processing the first sub-service, and the second available resource is used for processing the second sub-service. And the first network equipment sends the first sub-service to the second network equipment and sends the second sub-service to the third network equipment. And then, the first network device receives a first processing result of the first sub-service sent by the second network device and a second processing result of the second sub-service sent by the third network device respectively. It can be understood that the first network device may only save after receiving one or more of the first processing result and the second processing result according to the actual service requirement; or, after receiving one or more of the first processing result and the second processing result, continuing to perform subsequent service processing.

In the embodiment of the application, the network controller determines, for the first network device, a second network device capable of providing available resources for processing a service to be processed by the first network device, according to a request message sent by the first network device. Therefore, on one hand, the first network device can send the service to be processed to the second network device for processing, so that the resource consumption of the first network device is reduced, and the network use experience of the user equipment accessing the first network device is improved. On the other hand, due to the scheduling of the network controller to the resources, the idle resources of the second network device are utilized, and the utilization efficiency of the resources in the network is improved.

The following describes the resource allocation method provided in the embodiment of the present application by taking the fourth network device as a resource requester and the first network device as a resource provider as an example, and fig. 6 is a schematic flow chart of a resource allocation phase of another resource allocation method provided in the embodiment of the present application. Illustratively, the present embodiment may be applied to the network architecture shown in fig. 1. The method may be described, for example, when the first network device further has certain available resources and thus does not need to execute the method shown in fig. 5, or when the first network device has available resources for other network devices due to releasing its resources after completing one or more services using the resources of other network devices. The method shown in fig. 6 may include the steps of:

s300 to S302, referring to the execution steps in S200 to S202 specifically, the first network device is replaced with a fourth network device, and the second network device is replaced with the first network device, which is not described again.

S303: and the fourth network equipment sends the second service to be processed to the first network equipment according to the received identification information of the first network equipment. And the second service to be processed is the service to be processed in the fourth network device. The second pending service includes the authentication of the user identity, SAC, DPI or AI big data analysis, etc. 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 to-be-processed service to the first network device.

In another case, when the fourth network device receives the third identification information and the information of the third available resource of the first network device, the fourth network device sends the third sub-service to the first network device according to the third identification information and the information of the third available resource of the first network device. And the third sub-service belongs to the second service to be processed. The third available resource may be used to process a third sub-service.

It should be noted that the to-be-processed service of the fourth network device may be divided into a plurality of 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 may be the authentication of 40 user identities, and the fourth sub-service may be the authentication of 60 user identities.

S304: and the first network equipment acquires the processing result of the second service to be processed.

Illustratively, the first network device receives 100 user authentication services sent by the fourth network device. The first network device obtains the verification result of the 100 user identity verifications.

S305: and the first network equipment sends the processing result to the fourth network equipment.

Based on the example in S304, the first network device sends the verification result of the 100 user authentications to the fourth network device.

S306: and the first network equipment releases the resources for processing the second service to be processed.

Subsequently, after the first network device releases the resource, it may acquire its own resource usage information and send the latest resource usage information to the network controller. The resource usage information is used by the network controller to update the maintained available resource information of the first network device.

In this embodiment, the network controller determines, for the fourth network device, the first network device capable of providing the available resource for processing the service to be processed by the fourth network device according to the request message sent by the fourth network device. Therefore, on one hand, the fourth network device can send the service to be processed to the first network device for processing, so that the resource consumption of the fourth network device is reduced, and the network experience of the user equipment accessing the fourth network device is improved. On the other hand, due to the scheduling of the network controller to the resources, the idle resources of the first network device are utilized, and the utilization efficiency of the resources in the network is improved.

As can be seen from the embodiments shown in fig. 5 and fig. 6, the same network device may send its own pending service to another network device capable of providing processing resources for processing, and may also process the pending service sent by another network device when the available resources of the network device are relatively large. Therefore, the problem that the network use of the user equipment accessed to the network equipment is influenced due to overlarge resource consumption of individual network equipment caused by unbalanced resource utilization in the network is effectively solved, meanwhile, idle resources in the network can be utilized, and the resource utilization efficiency in the network is improved.
