In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 1, a system for allocating virtual processors in an embodiment of the present invention includes a virtual network function management VNFM10 and a virtualization infrastructure management VIM 20:

VNFM 10: the virtual processor vCPU combination information is determined according to the scene of the virtual machine which needs to be established; sending a creation request containing the vCPU combination information to a virtualized infrastructure management VIM20 to enable the VIM20 to allocate vcpus according to the vCPU combination information.

VIM 20: receiving a creation request sent by the VNFM 10; determining vCPU combination information in the creation request; and distributing the vCPU according to the vCPU combined information.

The method includes the steps that a plurality of scenes needing to establish the virtual machine are needed, for example, a server needs to be set up, a cloud host needs to be established, private cloud virtual machine resources need to be applied, public cloud virtual machine resources need to be applied, and the like.

The VNFM10 may determine the vCPU composition information according to a scene in which the virtual machine is established, where different scenes correspond to different vCPU composition information, that is, there is a correspondence between different scenes and the vCPU composition information; the corresponding relation between the scene and the vCPU combined information can be set manually or can be automatically distributed by the system.

The vCPU combined information only comprises vCPU main frequency information; or vCPU main frequency information and vCPU number information; or vCPU main frequency information and corresponding priority; or the vCPU main frequency information and vCPU number information and corresponding priority,

the vCPU main frequency information is used for the VIM20 to determine the main frequency of the vCPU, so that the vCPU with the determined main frequency is adopted when the virtual machine is created;

the vCPU master frequency information, vCPU number information corresponding to the vCPU master frequency information and vCPU priority can also be contained.

And the vCPU priority is a vCPU priority corresponding to the information combination of the vCPU main frequency information and the corresponding vCPU number information.

The vCPU number information is used for the VIM20 to determine the number of the vCPUs, so that the vCPUs with the determined number are adopted when the virtual machine is created;

the priority is used for vCPU main frequency information or vCPU number information which is selected by the VIM20 to be used according to the priority.

The following describes the above five cases separately.

The first method comprises the following steps: the vCPU combination information only contains vCPU main frequency information.

The vCPU combined information needs to contain at least one vCPU main frequency information, the vCPU main frequency information is selected according to different scenes, the vCPU combined information is more pertinent, a higher main frequency can be selected for scenes needing a higher processing capability of the vCPU, such as intensive data processing, software coding and decoding conversion and the like, and a lower main frequency is selected for scenes needing a lower processing capability of the vCPU, such as a front-end server and the like.

In implementation, the vCPU combination information may not include vCPU number information, but only include vCPU main frequency information. The number of vcpus may be set in a default manner, and the information on the number of vcpus is set in advance between VNFM10 and VIM20, and is used regardless of the current scenario.

After the VNFM10 establishes the virtual machine scenes as needed and determines the vCPU composition information, it sends a creation request including the vCPU composition information to the VIM 20.

The VIM20 receives a creation request sent by the VNFM 10;

the VIM20 determines vCPU combination information in the create request.

And the VIM20 allocates the vCPU according to the vCPU main frequency information contained in the vCPU combination information.

On the VIM20 side, such a case can be classified into a case of one vCPU master frequency information and a plurality of vCPU master frequency information.

1. The vCPU combined information comprises vCPU main frequency information;

the VIM20 judges whether the currently managed resource supports vCPU dominant frequency information contained in the vCPU combination information, if so, the vCPU is distributed according to the vCPU dominant frequency information; otherwise, the vCPU cannot be allocated, and a failure response may be sent to VNFM 10.

For example, the vCPU combination information includes vCPU dominant frequency information of 2.4GHz, the number of current default vcpus is 1, and only 1.8GHz vcpus are supported in the resources currently managed by the VIM20, so that the VIM20 does not support the vCPU dominant frequency information included in the vCPU combination information, and the vcpus cannot be allocated; if the resources currently managed by the VIM20 support the vCPU of 2.4GHz, the VIM20 supports the vCPU dominant frequency information included in the vCPU combination information, and can allocate the vCPU according to the vCPU dominant frequency information.

It should be noted that, the VIM20 manages some CPUs with a certain main frequency and a certain number of cores, and the VIM20 can use the managed CPUs to virtualize a certain main frequency and a certain number of vcpus; that is, the currently managed resource support means that the CPU managed by VIM20 can be virtualized as a eligible vCPU.

2. The vCPU combined information comprises a plurality of vCPU main frequency information;

the VIM20 selects vCPU dominant frequency information supported by the VIM20 from vCPU dominant frequency information contained in the vCPU combination information;

and the VIM20 allocates the vCPU according to the selected vCPU main frequency information.

For example, the two vCPU main frequency information included in the vCPU combination information are 2.4GHz and 1.8GHz, the number of current default vcpus is 1, and only 1.8GHz vcpus are supported in the resources currently managed by the VIM20, so that the VIM20 supports 1.8GHz vCPU main frequency information included in the vCPU combination information, and the VIM20 allocates vcpus according to the vCPU main frequency information; if the resources currently managed by the VIM20 support the vCPU of 2.4GHz, the VIM20 supports the main frequency information of the vCPU of 2.4GHz included in the vCPU combination information, and can allocate the vCPU according to the main frequency information of the vCPU.

If the vCPU combination information contains a plurality of vCPU master frequency information, and the resources currently managed by the VIM20 all support the vCPU master frequency information contained in the vCPU combination information, the VIM20 may select one vCPU master frequency information according to the order of master frequencies in the combination information, or may establish a master frequency priority order between the VIM20 and the VNFM10 in advance, and select the vCPU master frequency information according to the priority order of the supported vCPU master frequency information;

for example, the two vCPU master frequency information included in the vCPU combined information are 2.4GHz and 1.8GHz, the sequence in the combined information is 2.4GHz and 1.8GHz, and the VIM20 may select the first 2.4GHz vCPU master frequency information according to the sequence of the master frequencies in the combined information, and may also select the last 1.8GHz vCPU master frequency information according to the sequence of the master frequencies in the combined information; or, a dominant frequency priority order may be established in advance between the VIM20 and the VNFM10, for example, the established dominant frequency priority order is 1.2GHz, 1.8GHz, and 2.4GHz, where 1.8GHz is prior to 2.4GHz, and then the VIM20 selects 1.8GHz vCPU dominant frequency information;

and the second method comprises the following steps: the vCPU combined information comprises vCPU main frequency information and vCPU number information.

The vCPU combination information may further include at least one vCPU number information. According to different scenes, besides selecting the main frequency of the vCPU, the number information of the vCPU can be increased; by adopting the mode of the combined information, the flexibility of allocating the vCPU aiming at the scene can be improved; for scenes requiring the vCPU to have higher processing capacity, such as intensive data processing, software coding and decoding conversion and the like, the number of the vCPUs can be increased besides the selection of higher main frequency; for a scene with lower requirements on the processing capacity of the vcpus, such as a front-end server, besides selecting a lower main frequency, the number of the vcpus can be reduced appropriately.

The VIM20 receives a creation request sent by the VNFM 10;

the VIM20 determines vCPU combination information in the create request.

On the VIM20 side, such a case can be classified into a case of one vCPU dominant frequency information, one vCPU number information, a plurality of vCPU dominant frequency information, and a plurality of vCPU number information.

1. The vCPU combined information comprises vCPU main frequency information and vCPU number information;

the VIM20 judges whether the currently managed resources support vCPU main frequency information and vCPU number information contained in the vCPU combination information, if so, the vCPU is distributed according to the vCPU main frequency information and the vCPU number information; otherwise, the vCPU cannot be allocated, and a failure response may be sent to VNFM 10.

For example, the vCPU combination information includes vCPU dominant frequency information of 2.4GHz, vCPU number information of 8, and the resource currently managed by the VIM20 only supports 8 vcpus of 1.8GHz, so that the resource currently managed by the VIM20 does not support the vCPU dominant frequency information and the vCPU number information included in the vCPU combination information, and the vcpus cannot be allocated; if the resources currently managed by the VIM20 support 4 vcpus of 2.4GHz, the resources currently managed by the VIM20 do not support the vCPU dominant frequency information and the vCPU number information contained in the vCPU combination information, and the vcpus cannot be allocated; if the resources currently managed by the VIM20 support 10 vcpus of 2.4GHz, the resources currently managed by the VIM20 support vCPU combination information including vCPU dominant frequency information and vCPU number information, and the VIM20 may allocate vcpus according to the vCPU dominant frequency information.

2. The vCPU combination information comprises a plurality of vCPU main frequency information and a plurality of vCPU number information;

the vCPU combined information comprises a plurality of vCPU main frequency information and a plurality of vCPU number information, wherein one vCPU main frequency information corresponds to one vCPU number information to form a plurality of data pairs; the VIM20 determines the supported data pairs and selects one data pair from among them for assignment to the vCPU.

If the VIM20 only supports one of the data pairs, then the vCPU is assigned based on the supported data pair.

If the VIM20 supports multiple data pairs, the VIM20 may select one vCPU master frequency information and one vCPU number information according to the order of the master frequency information and the number information in the combined information, or may establish a priority order of the master frequency and the number between the VIM20 and the VNFM10 in advance, and according to the priority order of the supported vCPU master frequency information and the vCPU number information;

for example, the vCPU combination information includes two vCPU dominant frequency information and two vCPU number information, corresponding to two data pairs of 2.4GHz, 4, 1.8GHz, and 4, the order in the combination information is 2.4GHz, 4, 1.8GHz, and 2, and the VIM20 may select the first 2.4GHz vCPU dominant frequency information and 4 vCPU number information according to the order in the combination information, or may select the last 1.8GHz vCPU dominant frequency information and 2 vCPU number information according to the order of dominant frequencies in the combination information; or, a dominant frequency and number priority order may be established between the VIM20 and the VNFM10 in advance, for example, the established dominant frequency and number priority order is 1.2GHz, 6, 1.8GHz, 2, 2.4GHz, 4, where 1.8GHz and 2 are prior to 2.4GHz and 4, the VIM20 selects 1.8GHz vCPU dominant frequency information and 2 vCPU number information;

and the third is that: the vCPU combined information comprises vCPU main frequency information and corresponding priority.

When the combined information includes a plurality of major frequency information, the vCPU combined information may include a priority corresponding to the vCPU major frequency information, so that the VIM20 selects the vCPU major frequency information to be used according to the priority.

For example, the combined information includes two vCPU master frequency information, 2.4GHz and 1.8GHz, and the number of the current default vcpus is 4; the priority corresponding to 2.4GHz is 1, and the priority corresponding to 1.8GHz is 2; the priority corresponding to 2.4GHz is higher than that corresponding to 1.8GHz, and when the VIM20 supports 4 2.4GHz vCPUs, the vCPU main frequency information of 2.4GHz can be preferentially selected; only when the VIM20 does not support 4 2.4GHz vcpus and supports 4 1.8GHz vcpus, the vCPU dominant frequency information of 1.8GHz can be selected.

The VIM20 receives a creation request sent by the VNFM 10;

the VIM20 determines vCPU combination information in the create request.

And the VIM20 selects vCPU main frequency information which is supported by the VIM20 and has the highest corresponding priority from at least one vCPU main frequency information contained in the vCPU combination information.

For example, the combined information includes two vCPU master frequency information, 2.4GHz and 1.8GHz, and the number of the current default vcpus is 4; the priority corresponding to 2.4GHz is 1, and the priority corresponding to 1.8GHz is 2; the priority corresponding to 2.4GHz is higher than that corresponding to 1.8GHz, and when the resources currently managed by the VIM20 support 4 2.4GHz vcpus and also support 4 1.8GHz vcpus, the VIM20 can preferentially select 2.4GHz vCPU dominant frequency information; when the resources currently managed by the VIM20 do not support 4 2.4GHz vcpus and support 4 1.8GHz vcpus, the VIM20 may select vCPU dominant frequency information of 1.8 GHz.

And fourthly: the vCPU combined information comprises vCPU main frequency information, vCPU number information and corresponding priority.

The vCPU number information is vCPU number information corresponding to priority corresponding to the vCPU main frequency information;

in the vCPU combined information, the number of vCPUs can be configured for the main frequency; one piece of vCPU main frequency information and one piece of vCPU number information correspond to one priority; for example, in the combined information, the dominant frequency 2.4GHz, the priority corresponding to the number 4 is 1, the dominant frequency 2.4GHz, the priority corresponding to the number 2 is 2, the dominant frequency 1.8GHz, the priority corresponding to the number 4 is 3, the dominant frequency 1.8GHz, and the priority corresponding to the number 2 is 4.

The VIM20 receives a creation request sent by the VNFM 10;

the VIM20 determines vCPU combination information in the create request.

And the VIM20 allocates the vCPUs according to the selected vCPU main frequency information and the corresponding vCPU number information.

For example, the combined information includes three vCPU main frequency information and three vCPU number information; when the currently managed resources of the VIM20 do not support 8 2.4GHz vcpus, support 4 2.4GHz vcpus and also support 8 1.8GHz vcpus, the VIM20 can preferentially select 4 vCPU number information and 2.4GHz vCPU main frequency information; when the resources currently managed by the VIM20 do not support 8 2.4GHz vcpus, do not support 4 2.4GHz vcpus, and support 4 1.8GHz vcpus, the VIM20 may select the vCPU dominant frequency information of 1.8GHz and the vCPU number information of 4.

And fifthly, the vCPU combination information comprises vCPU main frequency information, vCPU number information corresponding to the vCPU main frequency information and vCPU priority.

In the vCPU combined information, the number of vCPUs can be configured for the main frequency; the information combination of one vCPU main frequency information and one vCPU number information can be configured to correspond to one priority; for example, in the combined information, the dominant frequency is 2.4GHz, the number is 4, the priority corresponding to the combination of the dominant frequency 2.4GHz and the number 4 information is 1, the dominant frequency is 2.4GHz, the priority corresponding to the combination of the number 2 and the dominant frequency 2.4GHz and the number 2 information is 2, the priority corresponding to the dominant frequency is 1.8GHz, the priority corresponding to the number 4 and the combination of the dominant frequency 1.8GHz and the number 4 information is 3, the priority corresponding to the dominant frequency is 1.8GHz, and the priority corresponding to the combination of the number 2 and the dominant frequency 1.8GHz and the number 4 information is 4.

The VIM20 receives a creation request sent by the VNFM 10;

the VIM20 determines vCPU combination information in the create request.

For example, the combined information includes three vCPU main frequency information and three vCPU number information; the number of the dominant frequencies is 8 and 2.4GHz, the priority corresponding to the information combination of the dominant frequencies 2.4GHz and 8 is 1, the priority corresponding to the information combination of the dominant frequencies 2.4GHz and 8 is 2, the priority corresponding to the information combination of the dominant frequencies 2.4GHz and 4 is 1.8GHz, and the number of the dominant frequencies is 8, the priority corresponding to the information combination of the dominant frequencies 1.8GHz and 8 is 3, and the priority corresponding to the 2.4GHz is higher than the priority corresponding to the 1.8GHz, when the resources currently managed by the VIM20 do not support 8 2.4GHz vcpus, support 4 2.4GHz vcpus, and also support 8 1.8GHz vcpus, the VIM20 can preferentially select 4 vCPU number information and 2.4GHz dominant frequency vCPU information; when the resources currently managed by the VIM20 do not support 8 2.4GHz vcpus, do not support 4 2.4GHz vcpus, and support 4 1.8GHz vcpus, the VIM20 may select the vCPU dominant frequency information of 1.8GHz and the vCPU number information of 4.

If the currently managed resources do not support the vCPU composition information, the VIM20 sends a create failure response to the VNFM 10.

According to different scenes, besides selecting the main frequency of the vCPU, the number information of the vCPU can be increased; by adopting the mode of combining the information, the flexibility of allocating the vCPU aiming at the scene can be improved.

When the combined information contains a plurality of main frequency information, the vCPU combined information may contain a priority corresponding to the vCPU main frequency information, so that the VIM selects the vCPU main frequency information to use according to the priority.

After the first determining module 201 determines vCPU combination information by creating a virtual machine scene as needed, the first transmitting module 202 sends a creation request including the vCPU combination information to the VIM.

If the processing module 303 supports only one of the data pairs, then the vcpus are assigned according to the supported data pair.

the vCPU combined information comprises a plurality of vCPU main frequency information and a plurality of vCPU number information, wherein one vCPU main frequency information corresponds to one vCPU number information to form a plurality of data pairs; the VIM determines the supported data pairs and selects one data pair from among them for assignment to the vCPU.

If the VIM supports only one of the data pairs, then the vCPU is allocated according to the supported data pair.

If the VIM supports a plurality of data pairs, the VIM can select one vCPU main frequency information and one vCPU number information according to the sequence of the main frequency information and the number information in the combined information, or can establish a priority sequence of the main frequency and the number between the VIM and the VNFM in advance and according to the supported priority sequence of the vCPU main frequency information and the vCPU number information;

And the VIM selects vCPU main frequency information which is supported by the VIM and has the highest corresponding priority from at least one vCPU main frequency information contained in the vCPU combined information.

And the VIM allocates the vCPU according to the selected vCPU main frequency information and the corresponding vCPU number information.

As shown in fig. 6, by taking the example that the combination information includes the main frequency information and the number information and the priority corresponding to the combination information, the process of allocating virtual processors in the embodiment of the present invention is schematically illustrated,
