Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a resource control method for a network slice according to the present invention is shown, where the network slice includes a virtualized network function component, a virtual network function object, and a network service component, and specifically may include the following steps:

step 101, acquiring resource information of a virtualized network function component, resource information of a virtual network function object, and resource information of a network service component of the network slice.

In practical applications, a Network slice may include a Virtual Network Function Component (VNFC), a Virtual Network function object (VNF), and a Network Service component (NS), and the resource control on the Network slice may be resource control on the VNFC, the VNF, and the NS.

As shown in fig. 2, which is a schematic diagram of resource control on a network slice according to an embodiment of the present invention, in fig. 2, a resource control method on a network slice is divided into VNFCs, VNFs, and NS for the network slice, and specifically, the resource control on the network slice is divided into VNFC level (lower level), VNF level (middle level), and NS level (upper level).

As shown in fig. 3, which is a schematic view of resource control of each hierarchy according to the embodiment of the present invention, specifically, the resource control method uses a lifecycle control procedure of each hierarchy to control an instance of each hierarchy, that is, the resource control method of the NS uses a lifecycle control procedure of the NS to control an instance of the NS; the resource control method of the VNF is to control the instance of the VNF by using a lifecycle control program of the VNF; the resource control method for the VNFC is to control an instance of the VNF using a lifecycle control program of the VNFC.

As shown in fig. 4, resource control can be performed from four dimensions for each level, namely, a horizontal dimension, a vertical dimension, a depth dimension, and a time dimension. The vertical dimension is the increase or decrease of resources used by the instance in the hierarchy; the transverse dimension is the increase or decrease of the number of instances in the hierarchy; the depth dimension is used for controlling switching, migration, restarting and the like of high-reliability cluster related instances of the hierarchy, and the time dimension is used for controlling the horizontal dimension, the vertical dimension and the depth dimension in the hierarchy along with time change.

Different resource information can be collected for each dimension to serve as the basis for controlling the application of the method, for example, the use information of example resources collected in the longitudinal dimension serves as the basis for the application of the method; collecting service capacity on a transverse dimension as the basis of method application, collecting case fault alarm states on a depth dimension as the basis of method application, and arranging corresponding actions according to time on a time dimension. Therefore, the acquired resource information of the VNFC includes a first instance resource usage amount, a first service capacity, a first instance fault alarm state, and a first time schedule; the acquired resource information of the VNF comprises the resource usage amount of the second instance, the second service capacity, the fault alarm state of the second instance and second time arrangement; the obtained NS includes a third instance resource usage amount, a third service capacity, a third instance fault alarm state, and a third time schedule.

Step 102, generating first decision information according to the resource information of the virtualized network function component, generating second decision information according to the resource information of the virtualized network function object, and generating third decision information according to the resource information of the network service component.

In this embodiment of the present invention, if a VNFC resource controller is provided, in step 102, the step of generating first decision information according to the resource information of the virtualized network function component may include:

substep S11, obtaining a first description file of the virtualized network functional component, where the first description file includes a first preset instance resource usage threshold, a first preset service capacity threshold, first preset instance fault warning information, and a first preset time schedule;

substep S12, determining whether the usage amount of the first instance resource is greater than the first preset instance resource usage threshold, and/or determining whether the first service capacity is greater than the first preset service capacity threshold, and/or determining whether the first instance fault alarm state matches the first preset instance fault alarm information, and/or determining whether the first time schedule matches the first preset time schedule;

and a substep S13, obtaining decision information corresponding to the first preset instance resource usage threshold, and/or decision information corresponding to the first preset service capacity threshold, and/or decision information corresponding to the first preset instance fault alarm information, and/or decision information respectively corresponding to the first preset time arrangement as the first decision information.

The VNFC resource controller needs to cooperate with a first description file (VNFC description file), VNFM, VIM (virtualized infrastructure Manager) to complete the resource control process. The information of the VNFC in four dimensions and the decision information corresponding to the four dimensions are described in the first description file, for example, a first preset instance resource usage threshold and the decision information corresponding to the first preset instance resource usage threshold, a first preset service capacity threshold and the decision information corresponding to the first preset service capacity threshold, first preset instance fault alarm information and the decision information corresponding to the first preset instance fault alarm information, and first preset time arrangement and the decision information corresponding to the first preset time arrangement.

The VNFC resource controller analyzes and monitors instantiated VNFC resources, the VNFM and the VIM are responsible for reporting changes of resource information to the VNFC resource controller, the VNFC resource controller obtains first decision information according to the resource information, information of four dimensions in the first description file and decision information corresponding to the four dimensions, namely the first decision information can be decision information made according to at least one dimension of the four dimensions, and after the first decision information is obtained, the VNFM and the VIM execute operation of the first decision information. To facilitate those skilled in the art to understand the step of generating the first decision information according to the resource information of the virtualized network function component according to the embodiment of the present invention, the following description is made by way of example with reference to the accompanying drawings:

as shown in fig. 5, the first description file includes information of four dimensions and decision information corresponding to the four dimensions, as follows:

the first description file:

first instance resource usage threshold 1: action1

First instance resource usage threshold 2: action2

First instance resource usage threshold 3: action3

First traffic capacity threshold 1: action1

First traffic capacity threshold 2: action2

First traffic capacity threshold 3: action3

First example failure warning information 1: action1

First-instance fault warning information 2: action2

First-instance fault warning information 3: action3

First time schedule 1: action1

First time schedule 2: action2

First time schedule 3: action3

In this example, each dimension may be divided into three steps, for example, the first preset instance resource usage threshold may be set to threshold 1, threshold 2 and threshold 3, and the corresponding action1, action2 and action3 are set. After the first instance resource usage amount is obtained, it is determined whether the first instance resource usage amount is greater than one of a preset threshold 1, a threshold 2, and a threshold 3, if so, a corresponding action is obtained, for example, the first instance resource usage amount is greater than the threshold 3, the decision information is action3, and of course, only a first-level threshold may be set, which is not limited in this embodiment of the present invention.

And for example fault alarm information and time arrangement, a matching method can be adopted to obtain corresponding decision information, and at least one decision information is finally used as first decision information.

According to the embodiment of the invention, the first decision information of the VNFC is generated according to the resource usage amount of the first instance of the VNFC, the first service capacity, the fault alarm state of the first instance and the first time arrangement of the resource information of four dimensions, so that the resource coverage is wide, and the resources of the VNFC can be more comprehensively controlled.

In this embodiment of the present invention, if a virtual network function object resource controller is provided, in step 102, the step of generating second decision information according to the resource information of the virtual network function object may include:

substep S21, obtaining a second description file of the virtual network function object, where the second description file includes a second preset instance resource usage threshold, a second preset service capacity threshold, second preset instance fault warning information, and a second preset time arrangement, where the second preset instance resource usage threshold is greater than the first preset instance resource usage threshold, and the second preset service capacity threshold is greater than the first preset service capacity threshold;

substep S22, determining whether the usage amount of the second instance resource is greater than the second preset instance resource usage threshold, and/or determining whether the second service capacity is greater than the second preset service capacity threshold, and/or determining whether the second instance fault alarm state matches the second preset instance fault alarm information, and/or determining whether the second time schedule matches the second preset time schedule;

and a substep S23, obtaining decision information corresponding to the second preset instance resource usage threshold, and/or decision information corresponding to the second preset service capacity threshold, and/or decision information corresponding to the second preset instance fault alarm information, and/or decision information respectively corresponding to the second preset time arrangement as second decision information.

The VNF resource controller needs to work in cooperation with a second description file (VNF description file), VNFM, VIM to complete the resource control process. The second description file describes resource information of four dimensions of the VNF and decision information corresponding to the four dimensions, such as a second preset instance resource usage threshold and its corresponding decision information, a second preset service capacity threshold and its corresponding decision information, a second preset instance fault alarm information and its corresponding decision information, and a second preset time schedule and its corresponding decision information.

The VNF resource controller analyzes and monitors instantiated VNF resources, the VNFM and the VIM are responsible for reporting the change of the resource information to the VNF resource controller, the VNF resource controller obtains second decision information according to the resource information, the information of the four dimensions in the second description file and the decision information corresponding to the four dimensions, namely the second decision information can be decision information made according to at least one dimension of the four dimensions, and after the second decision information is obtained, the VNFM and the VIM execute the operation of the second decision information.

It should be noted that the threshold design of each dimension of the VNF resource controller and the VNFC resource controller is related, and a certain resource control principle and order are designed to eliminate duplication and conflict when implemented. The resource control principle is that lower-level resource control is executed first, and then upper-level resource control is executed, specifically, the upper-level resource controller only focuses on the threshold values of all the instances of the current level, and the threshold value of the instance of the current level is greater than the threshold value of the instance of the lower level. For example, the VNF tier collects online user occupancy information in the vertical direction, when the total number of users reaches 80%, the action is to increase the VNFC, the threshold of the VNF tier is not conflicted with the threshold of the VNFC tier, and the threshold (80%) of the VNF tier is greater than the threshold (70%) of the VNFC tier.

To facilitate those skilled in the art to understand the step of generating the second decision information according to the resource information of the virtual network function object in the embodiment of the present invention, the following description is made by way of example with reference to the accompanying drawings:

as shown in fig. 6, the second description file includes information of four dimensions and decision information corresponding to the four dimensions, as follows:

Second traffic capacity threshold 1: action1

Second traffic capacity threshold 2: action2

Second traffic capacity threshold 3: action3

Second example fault warning information 2: action2

Second example failure warning information 3: action3

Second time schedule 1: action1

Second time schedule 2: action2

Second time schedule 3: action3

In this example, each dimension may be divided into three steps, for example, the second preset instance resource usage threshold may be set to threshold 1, threshold 2 and threshold 3, and the corresponding action1, action2 and action3 are set. After the second instance resource usage is obtained, it is determined whether the second instance resource usage is greater than one of preset threshold 1, threshold 2, and threshold 3, if so, a corresponding action is obtained, for example, greater than threshold 3, the decision information is action3, and of course, only a first-level threshold may be set, which is not limited in this embodiment of the present invention.

And for example fault alarm information and time arrangement, a matching method can be adopted to obtain corresponding decision information, and at least one decision information is finally used as second decision information.

According to the embodiment of the invention, the resource information of four dimensions is arranged according to the resource usage amount of the second instance of the VNF, the second service capacity, the fault alarm state of the second instance and the second time, so that the second decision information of the VNF is generated, the resource coverage is wide, and the resources of the VNF can be controlled more comprehensively.

In this embodiment of the present invention, if an NS resource controller is provided, in step 102, the step of generating third decision information according to the resource information of the network service component may include:

substep S31, obtaining a third description file of the network service component, where the third description file includes a third preset instance resource usage threshold, a third preset service capacity threshold, third preset instance fault warning information, and a third preset time schedule, where the third preset instance resource usage threshold is greater than the second preset instance resource usage threshold, and the third preset service capacity threshold is greater than the second preset service capacity threshold;

The NS resource controller needs to work in cooperation with a third description file (VNF description file), NFVO, VNFM, and VIM to complete the resource control process. The third description file describes resource information of four dimensions of the VNF and decision information corresponding to the four dimensions, such as a third preset instance resource usage threshold and its corresponding decision information, a third preset service capacity threshold and its corresponding decision information, third preset instance fault alarm information and its corresponding decision information, and a third preset time schedule and its corresponding decision information.

The NS resource controller analyzes and monitors instantiated NS resources, the NFVO is responsible for reporting changes of resource information to the NS resource controller, the NS resource controller obtains third decision information according to the resource information, the four-dimensional information in the third description file and the decision information corresponding to the four dimensions, namely the third decision information can be decision information made according to at least one dimension of the four dimensions, and the NFVO, the VNFM and the VIM execute the operation of the third decision information after the third decision information is obtained.

It should be noted that the threshold design of each dimension of the NS resource controller and the VNF resource controller is related, and a certain resource control principle and order are designed to eliminate duplication and conflict when implemented. The resource control principle is that lower-level resource control is executed first, and then upper-level resource control is executed, specifically, the upper-level resource controller only focuses on the threshold values of all the instances of the current level, and the threshold value of the instance of the current level is greater than the threshold value of the instance of the lower level. For example, the VNF level collects online user occupancy information in the longitudinal direction, when the total number of users reaches 80%, the action is to increase the VNFC, the threshold of the NS level is not to conflict with the threshold of the VNF level, the threshold (90%) of the NS level is greater than the threshold (80%) of the VNF level, specifically, in the embodiment of the present invention, the threshold of the third preset instance resource usage is greater than the threshold of the second preset instance resource usage, the threshold of the third preset service capacity is greater than the threshold of the second preset service capacity, the fault warning information of the third preset instance is not to conflict with the fault warning information of the second preset instance, and the third preset time arrangement is not to conflict with the second preset time arrangement, so that resource control of the lower level is performed first during resource control, and then resource control of the upper level is performed.

To facilitate those skilled in the art to understand the step of generating the third decision information according to the resource information of the NS in the embodiment of the present invention, the following description is made by way of example with reference to the accompanying drawings:

as shown in fig. 7, the third description file includes information of four dimensions and decision information corresponding to the four dimensions, as follows:

Third example failure warning information 1: action1

Third example failure warning information 2: action2

Third example failure warning information 3: action3

Third time schedule 1: action1

Third time schedule 2: action2

Third time schedule 3: action3

In this example, each dimension may be divided into three steps, for example, the third preset instance resource usage threshold may be set to threshold 1, threshold 2 and threshold 3, and the action1, action2 and action3 are correspondingly set. After the third instance resource usage amount is obtained, it is determined whether the third instance resource usage amount is greater than one of preset threshold 1, threshold 2, and threshold 3, if so, a corresponding action is obtained, for example, greater than threshold 3, the decision information is action3, and of course, only a first-level threshold may be set, which is not limited in this embodiment of the present invention.

And for example fault alarm information and time arrangement, a matching method can be adopted to obtain corresponding decision information, and at least one decision information is finally used as third decision information.

According to the embodiment of the invention, the third decision information of the NS is generated according to the resource information of four dimensions of the third instance resource usage amount, the third service capacity, the third instance fault alarm state and the third time arrangement of the NS, the resource coverage is wide, and the resources of the NS can be more comprehensively controlled.

as shown in fig. 8, the network slice of this example includes three hierarchies of NS, VNF and VNFC, where the NS includes at least one VNF and one VNF includes at least one VNFC, and the resource control method of the network slice may be to control resources from four dimensions of the three hierarchies of NS, VNF and VNFC.

The resource control at the VNFC level is illustrated below with reference to fig. 9, 10 and 11:

fig. 9 is a schematic diagram of controlling resources in a vertical dimension of a VNFC hierarchy.

In the longitudinal dimension, the VNFC resource controller monitors the use information of resources such as a memory, a CPU, a disk, and the like of each VNFC, and if the resource use of a certain VNFC reaches a first preset instance resource use threshold in the first description file, the VNFC resource controller uses more NFVI resources through the VIM. For example, VNFC1 in VNF1 becomes VNFC1large, and VNFC3 in VNF2 becomes VNFC3 large.

As shown in fig. 10, the resource control diagram is a horizontal dimension of the VNFC hierarchy.

In the horizontal dimension, the VNFC resource controller monitors the traffic load condition of each VNFC, for example, if the number of business connections processed by a certain VNFC exceeds a first traffic capacity threshold, scale out is performed by performing horizontal dimension expansion, and the number of VMs (Virtual machines) used by the VNFC is increased, for example: the VNFC3 in the VNF3 is added with VMs, and the function of the VNFC3 is originally implemented by one VM, and is expanded to be implemented by two VMs.

As shown in fig. 11, a depth dimension resource control diagram of a VNFC hierarchy is shown.

In the depth dimension, the decision information corresponding to the first preset instance fault warning information read by the VNFC resource controller to the VNFC2 in the VNF1 is fault migration, and when the warning state of the physical server where the VNFC2 is monitored matches the first preset instance fault warning information, the VNFC2 is live migrated to another physical server.

In the time dimension, the resource control in the time dimension is generally related to the traffic capacity, for example, VNF2 is related to video traffic, the first preset time schedule of VNFC2 in VNF2 is that the number of VMs is in the range of 1-3, the number of VMs is the maximum number of instances 3 at 19 pm, 23 pm, 1 at 1 to 7 pm, and 2 at other times, and when in the above time period, the corresponding operation is performed.

The above examples illustrate resource control in the vertical, horizontal, depth, and time dimensions of the VNFC level.

VNF-level resource control is illustrated below in connection with figures 12, 13 and 14:

fig. 12 is a schematic diagram of controlling resources in a vertical dimension of a VNF hierarchy.

In a longitudinal dimension, the VNF resource controller monitors usage information of instance resources of each VNF, and if a number of the service resources of a certain VNF, for example, the VNF1, occupying the database object storage resource reaches a second preset instance resource usage threshold, the VNF resource controller enables a VNF1 with a larger resource configuration. For example, VNF1 within the NS becomes VNF1 large. VNF1large is different from the original VNF1 in that the total amount of service resources related to VNF1 that are commonly occupied when VNFC1 and VNFC2 cooperate to complete the function of VNF1 is different, and such resources belong to VNF1 and do not belong to visible resources on the VNFC level.

Fig. 13 is a schematic diagram of resource control in the horizontal dimension of the VNF hierarchy.

In the horizontal dimension, the VNF resource controller monitors the service KPI load condition of each VNF, and if the service KPI load data exceeds a second preset service capacity threshold, for example, the total number of service plane access user connections designed and carried by VNF3 is 10000, the second preset service capacity threshold is 8000, when the total number of service plane access user connections of VNF3 exceeds 8000, the horizontal direction expansion is performed, and the number of instances in VNF3 is increased, for example, the VNFC in VNF3 is expanded to a multi-instance state to carry more service plane user connections, that is, the internal VNFC instance number is increased or decreased in the horizontal dimension, and the increase or decrease is based on monitoring the KPI load data of the VNF.

Fig. 14 is a schematic view of the VNF-level depth dimension resource control.

In the depth dimension, the VNF resource controller monitors the health state and alarm information condition of each VNF, the decision information corresponding to the second preset instance fault alarm information may be the enabled standby VNF, and when it is monitored that the fault information of the VNF matches the second preset instance fault alarm information, the enabled standby VNF of the faulty VNF is actively closed. For example, when the primary instance of the VNF1 is closed, the standby instance of the VNF1 is enabled, and a high availability effect is achieved.

In the time dimension, the second preset time schedule may be busy time, normal time and idle time, for example, VNF3 is related to high bandwidth traffic, the second preset time schedule of VNF3 is that the VNFC number range in VNF3 is 1-3, the VNFC number is 3 as the maximum number of instances at 19 hours-23 hours at night every day, the VNFC number is 1 from 1 hour to 7 hours, and the VNFC number at other times is 2, and when the corresponding time period is reached, the VNFC number is controlled and adjusted.

The above examples illustrate resource control in the longitudinal, lateral, depth and time dimensions of the VNF level.

The resource control at the NS level is illustrated below in conjunction with fig. 15:

in the longitudinal dimension, the NS resource controller monitors the use condition of the total resources of the NS, and if the number of the resources occupied by the NS reaches a third preset instance resource use threshold value, the NS resource controller enables the NS with larger resource configuration. The resources of the NS refer to service resources of a network service level, are resources occupied by the cooperative work of multiple VNFs in the NS, and do not belong to certain VNF capacity expansion.

In the horizontal dimension, the NS resource controller monitors the KPI service load of the NS, and if the NS service KPI service load data exceeds a third preset service capacity threshold, for example, the total connection number of NS design access users is 20000, and the third preset service capacity threshold is 16000, when the total connection number of NS users exceeds 16000, the horizontal dimension is expanded, and the number of VNF instances in the NS is increased, as shown in fig. 15: the VNFs 2 and 3 in the NS are extended to a multi-instance state, that is, the number of VNF instances in the NS is increased or decreased in the transverse dimension according to monitoring KPI traffic load data of the NS.

In the depth dimension, the NS resource controller is generally not available, because the NS resource controller is expensive to perform resource control in the depth dimension, a set of backup NS is required, the NS resource controller monitors the health status of the NS, and when the NS service is unavailable and the service cannot be restored through the VNF and the VNFC, the backup NS is enabled to terminate the current NS.

In the time dimension, the resource control of the NS time dimension is also designed to be busy, normal and idle, and is extended at different times, that is, the number of VNF instances in the NS is increased or decreased according to the difference of the times.

In the embodiment of the invention, the threshold values of the description files of the three levels of the virtualized network function component, the virtualized network function object and the network service component can be associated, so that the resource control of the lower level (the virtualized network function component) can be executed firstly, then the resource control of the middle level (the virtualized network function object) is executed, and finally the resource control of the upper level (the network service component) is executed, thereby avoiding the repetition and the conflict of the resource control.
