Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and 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.
As shown in fig. 1, a method for determining virtual machine resources in an NFV environment is provided for an embodiment of the present invention, where an existing NFV architecture is as shown in fig. 1, and functional objects such as a network function virtualization infrastructure NFVI (NFVI), a Virtual Network Function (VNF), a Virtual Infrastructure Manager (VIM), a VNF Manager (VNF Manager, VNFM), a network function virtualization Orchestrator (NFV editor, NFVO), and a Virtual Network Function (VNF) are defined in the architecture.
The NFVI provides a cloud infrastructure layer, the VNF is a cloud network element application, and the NFVI and the VNF communicate through a Vn-Nf interface; the VIM is responsible for infrastructure layer management, the VNFM is responsible for life cycle management of the VNF, and the VNFM and the VIM are communicated through a Vi-Vnfm interface; the NFVO is responsible for the life cycle management of the service; an Operation Support System (OSS)/service support system (BSS) is a network manager of a cloud system, and the NFVO and the OSS/BSS are communicated through an Os-Nfvo interface; an Element Management System (EMS) is a network manager of a conventional CT telecommunication network element, which connects the OSS/BSS and the VNF. The deployment and operational behavior of each VNF is described by a template of a Virtualized Network Function Descriptor (VNFD) and is deposited in a VNF directory (VNF Catalog). NFV management and orchestration (MANO) uses VNFD to create VNF instances and manage the lifecycle of these instances. The VNFD has a one-to-one correspondence with the VNF package, and fully describes the characteristics and requirements necessary to implement one VNF. NFVI resources are allocated to VNFs based on the requirements described in the VNFD, while also taking into account specific requirements, constraints and policies set in advance.
As shown in fig. 2, the method for determining virtual machine resources provided in the embodiment of the present invention may be applied to an NFV architecture shown in fig. 1, and includes the following steps:
201. the VNFM determines parameters of the resources indicated by the VNFD;
the parameter of the resource indicated by the VNFD may be adjusted and set, for example, the parameter of the resource indicated by the VNFD may be set according to the parameter of the resource of Host. The specific implementation mode is as follows:
after the Host is started, the parameter of the resource of the Host is stored in the VIM, and the VNFM can obtain the parameter of the resource of the Host in the VIM through the Vi-VNFM interface, for example, there may be two ways as follows:
periodic checking
The VNFM periodically (e.g., once a minute frequency) sends a query request to the VIM, and the VIM sends the parameters of the resources of the Host to the VNFM, for example, the VIM may send the parameters of the resources of the Host to the VNFM through a Vi-VNFM interface.
2, triggering report
When the Host is added or deleted, the VIM may call a Vi-VNFM interface between the Host and the VNFM in a reverse direction, and send parameters of resources of the Host to the VNFM.
In this embodiment, the parameters of the Host resource, the parameters of the VNFD-indicated resource, and the parameters of the VM resource all represent resource dimensions, and the most common three resource dimensions are taken as examples in the embodiment of the present invention, as shown in fig. 3, that is, the CPU Host frequency, the memory size, and the storage space. It is understood that the above three dimensions are only an exemplary example, one or more of which may be selected, and other resource dimensions may also be selected, and are not limited herein.
For example, when the parameters of the acquired Host resource are:
a CPU: 16 × 2.2G Hz, memory: 64GB, store: 16T
According to the parameter of the resource of the Host, the parameter manner of constructing the resource indicated by the VNFD is as follows:
according to the Host CPU frequency, the memory size, and the storage space of the Host, the parameters of the resources indicated by the VNFD are constructed in equal proportion, for example, the parameters of the resources indicated by the VNFD may be constructed as follows:
a CPU: 1 × 2.2G Hz, memory: 4GB, storing: 1T of the total weight of the steel,
of course, other specifications may be constructed, such as:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T, specifically constructing parameters of resources indicated by the VNFD, and also meeting the resources required by the operation service function, wherein the parameters can be understood as the minimum CPU main frequency, the minimum memory size and the minimum storage space required by meeting a certain service function;
for example, running a call service, the minimum resources required are:
a CPU: 1.4 × 2.2G Hz, memory: 3GB, storing: 0.7T, then in order to meet the resource required for operating the paging service, the parameter of the resource indicated by the VNFD should be greater than or equal to the resource required for operating the paging service, that is, each resource dimension needs to be greater than the resource required for operating the GIA call service, and at this time, the parameter specification of the resource indicated by the VNFD may be configured as:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T.
202. And the VNFM determines the parameters of the resources of the virtual machine VM according to the parameters of the resources indicated by the VNFD, and the parameters of the resources of the VM are proportional to the parameters of the resources indicated by the VNFD.
After determining the resource parameter indicated by the VNFD, for example, when the parameter of the resource indicated by the VNFD is determined as:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T;
then the specification of the VM is built according to equal proportions;
meanwhile, in order to ensure that the VM can satisfy the minimum resource required for operating the service function, the determined VM specification needs to be equal to or greater than the resource required for operating the sub-service function.
For example, a certain call service is operated, the whole service is divided into a plurality of sub-services, and a certain sub-service with the minimum required resource is selected as a reference, for example, the resources required by the sub-service are as follows:
CPU 0.5X 2.2G Hz, memory 1.5G Hz, store 0.4T
The VM may be built as:
CPU 0.5X 2.2G Hz, memory 2G Hz, memory 0.5T
The resources such as the CPU main frequency, the memory size and the storage space of the constructed VM can cover the minimum resource required by the operation of the minimum sub-service function, and are proportional to the parameters of the resources indicated by the VNFD.
According to the method for determining the resources of the virtual machine, provided by the embodiment of the invention, the parameters of the resources indicated by the VNFD are determined to be proportional to the parameters of the resources of the Host, so that the parameters of the resources of the VM are proportional to the parameters of the resources indicated by the VNFD, the parameter specification of the resources of the VM is reconstructed, and the resource fragments in the Host can be reduced to a great extent; furthermore, as the VM constructed as described above can greatly reduce the fragments, make full use of the Host resources, and when the service operation resources need to be increased, the fragment resources in the Host can be preferentially utilized, thereby reducing the chance of increasing another Host.
An embodiment of the present invention provides another method for determining resources of a virtual machine, where the method may be applied to an existing NFV architecture, and unlike the foregoing embodiment, a parameter of a resource indicated by a VNFD is fixed and is not adjustable. Specifically, as shown in fig. 4, the method includes the following steps:
401. the VNFM acquires parameters of the resources of the Host,
after the Host is started, the parameter of the resource of the Host is stored in the VIM, and the VNFM may obtain the parameter of the resource of the Host in the VIM through the Vi-VNFM interface, and specifically may obtain the parameter of the resource of the Host through periodic checking or triggering reporting, where the specific implementation manner is described in detail in the foregoing embodiments, and is not described here again.
402. And the VNFM determines the parameters of the resources of the VM according to the acquired parameters of the resources of the Host, wherein the parameters of the resources of the VM are proportional to the parameters of the resources of the Host.
Constructing parameters of the resources of the VM according to the proportion of the parameters of the resources of the Host, so that the parameters of the resources of the VM are proportional to the parameters of the resources of the Host;
for example, when the parameters of the acquired Host resource are:
a CPU: 16 × 2.2G Hz, memory: 64GB, store: the temperature of the waste water is 16T,
then the specification of the VM can be scaled down equally, so the parameters of the resources of the VM can be built as follows:
CPU 0.5X 2.2G Hz, memory 2G Hz, store 0.5T.
Optionally, in this embodiment, a parameter of a resource of the VM may also be constructed according to a ratio of a parameter of a resource indicated by the VNFD, so that the parameter of the resource of the VM is proportional to the parameter of the resource of the VNDF.
For example, when the VNFD preset by the manufacturer indicates that the resource parameters are:
a CPU: 3 × 2.2G Hz, memory: 12GB, store: 12T.
Then the parameters of the resources of the VM may be scaled down, for example, the parameters of the resources of the VM are built into the following specifications:
CPU 0.5X 2.2G Hz, memory 2T.
In order to ensure that the VM can run the sub-service function, the parameters of the determined resources of the VM need to be equal to or greater than the resources required for running the sub-service function;
for example, a certain call service is operated, the whole service is divided into a plurality of sub-services, and a certain sub-service with the minimum required resource is selected as a reference, for example, the resources required by the sub-service are as follows:
CPU 0.5X 2.2G Hz, memory 1.5G Hz, store 0.4T
The VM may be built as:
the CPU is 0.5 × 2.2G Hz, the memory is 1.5G Hz, and stores 0.4T, it can be understood that the VM may also be constructed in other specifications, and theoretically, as long as the specification is satisfied and is greater than or equal to the resource required for operating the service function, the resources such as the CPU main frequency, the memory size, the storage space, and the like of the constructed VM can cover the minimum resource required for operating the minimum sub-service function.
According to the method for determining the resources of the virtual machine, provided by the embodiment of the invention, the VM parameters are constructed according to the parameters of the resources indicated by the VNFD or the parameters of the resources of the Host, so that the parameters of the resources of the VM are in proportion to the parameters of the resources indicated by the VNFD or the parameters of the resources of the Host, the parameter specification of the resources of the VM is reconstructed, and the resource fragments in the Host can be reduced to a great extent; furthermore, as the VM constructed as described above can greatly reduce the fragments, make full use of the Host resources, and when the service operation resources need to be increased, the fragment resources in the Host can be preferentially utilized, thereby reducing the chance of increasing another Host.
An embodiment of the present invention provides an apparatus for determining virtual machine resources, as shown in fig. 5, including a first constructing unit 501, an obtaining unit 502, and a second constructing unit 503, which may be applied to the NFV architecture shown in fig. 1, and specifically may implement the steps shown in fig. 2:
a first constructing unit 501, configured to construct a parameter of a resource indicated by the VNFD;
in this embodiment, the parameter of the resource indicated by the VNFD may be adjusted and set, for example, the parameter of the resource indicated by the VNFD may be set according to the parameter of the resource of Host. The specific implementation mode is as follows:
after the Host is started, the parameter of the resource of the Host is stored in the VIM, and the obtaining unit 502 may obtain the parameter of the resource of the Host in the VIM through the Vi-Vnfm interface, for example, there may be the following two ways: and periodically checking and triggering a reporting mode.
In the periodic check mode, the obtaining unit 502 sends a query request to the VIM periodically (for example, at a frequency of once a minute), and the VIM sends the parameter of the resource of the Host to the VNFM, for example, the VIM may send the parameter of the resource of the query Host to the VNFM through a Vi-VNFM interface.
In the triggered reporting, when the Host is added or deleted, the VIM may call back a Vi-Vnfm interface with the device, and send the parameters of the resources of the Host to the device.
For example, when the parameters of the acquired Host resource are:
a CPU: 16 × 2.2G Hz, memory: 64GB, store: 16T
According to the parameter of the resource of the Host, the first constructing unit 501 constructs the parameter of the resource indicated by the VNFD as follows:
the resource parameters of the VNFD are constructed in equal proportion according to the Host frequency of the CPU, the memory size, and the storage space of the Host, for example, the resource parameters of the VNFD may be constructed as follows:
a CPU: 1 × 2.2G Hz, memory: 4GB, storing: 1T of the total weight of the steel,
of course, other specifications may be constructed, such as:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T, the parameter specification of the specifically constructed resources indicated by the VNFD is also required to meet the resources required by the operation service function, and can be understood as the minimum CPU main frequency, the minimum memory size and the minimum storage space required by meeting a certain service function;
for example, running a call service, the minimum resources required are:
a CPU: 1.4 × 2.2G Hz, memory: 3GB, storing: 0.7T, then in order to meet the resources required for running the paging service, the resource parameter of the VNFD should be greater than or equal to the resources required for running the paging service, that is, each resource dimension needs to be greater than the resources required for running the GIA call service, and at this time, the resource specification of the VNFD may be constructed as follows:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T.
A second constructing unit 503, configured to determine, according to the determined parameter of the resource indicated by the VNFD, a parameter of a resource of the virtual machine VM, where the parameter of the resource of the VM is proportional to the parameter of the resource indicated by the VNFD.
After determining the resource parameter indicated by the VNFD, for example, when the parameter of the resource indicated by the VNFD is determined as:
a CPU: 2 × 2.2G Hz, memory: 8GB, storing: 2T;
the second construction unit 503 constructs the specification of the VM according to the equal proportion;
meanwhile, in order to ensure that the VM can satisfy the minimum resource required for operating the service function, the determined VM specification needs to be equal to or greater than the resource required for operating the sub-service function.
For example, a certain call service is operated, the whole service is divided into a plurality of sub-services, and a certain sub-service with the minimum required resource is selected as a reference, for example, the resources required by the sub-service are as follows:
CPU 0.5X 2.2G Hz, memory 1.5G Hz, store 0.4T
The VM may be built as:
CPU 0.5X 2.2G Hz, memory 2G Hz, memory 0.5T
The resources such as the CPU main frequency, the memory size, the storage space and the like of the constructed VM can cover the minimum resource required by the operation of the minimum sub-service function, and are in proportion to the resource parameter specification of the VNFD.
According to the device for determining the resources of the virtual machine, provided by the embodiment of the invention, the first construction unit is used for constructing the parameter of the resources indicated by the VNFD to be proportional to the parameter of the resources of the Host, and the second construction unit is used for further determining the parameter of the resources of the VM, so that the parameter of the resources of the VM is proportional to the parameter of the resources indicated by the VNFD, and the parameter specification of the resources of the VM is reconstructed, so that the resource fragments in the Host can be reduced to a great extent; furthermore, as the VM constructed as described above can greatly reduce the fragments, make full use of the Host resources, and when the service operation resources need to be increased, the fragment resources in the Host can be preferentially utilized, thereby reducing the chance of increasing another Host.
