Description

Technical Field

Background

With the maturity of Network Function Virtualization (NFV) technology, traditional hardware-specific devices can be virtualized into software to be deployed in a general server, so that flexible scheduling of a network architecture and deployment of virtual services on demand (for example, a virtual routing function, a virtual switching function, etc.) are achieved. Specifically, deploying virtual services in a virtual machine requires allocating certain virtual resources to the virtual services to provide virtual services for different services.

However, in the above related art, the virtual resources are allocated to the virtual service, which is usually performed based on a fixed template. Because the fixed template comprises a fixed virtual resource allocation mode, for different services, resource waste can be caused or service requirements cannot be met, and thus resource allocation is unreasonable.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Before describing the resource allocation method provided by the present application in detail, the implementation environment (implementation architecture) related to the present application will be briefly described.

The resource allocation method provided by the embodiment of the invention can be suitable for a resource allocation system. Fig. 1 shows a schematic structural diagram of the resource allocation system. As shown in fig. 1, the resource allocation system 10 includes a resource allocation apparatus 11 and an electronic device 12. The resource allocation apparatus 11 is connected to the electronic device 12, and the resource allocation apparatus 11 and the electronic device 12 may be connected in a wired manner or in a wireless manner.

The resource allocation apparatus 11 may be configured to perform data interaction with the electronic device 12, for example, obtain initial resource information of the virtual service and service capability requirements of the target service from the electronic device 12, and send target resource information allocated for the virtual service to the electronic device.

Meanwhile, the resource allocation device 11 may be further configured to determine an initial service capability corresponding to the initial resource information, and adjust the initial service capability according to the service capability requirement of the target service and the initial service capability, so as to obtain the target resource information.

The electronic device 12 may be configured to perform data interaction with the resource allocation apparatus 11, for example, to send the initial resource information of the virtual service and the service capability requirement of the target service to the resource allocation apparatus 11.

The electronic device may be further configured to, after receiving the target resource information sent by the resource allocation apparatus 11, allocate resources for the virtual service according to the target resource information.

Optionally, the electronic device may be a physical machine, for example: desktop computers are also called desktop computers (desktop computers), mobile phones, tablet computers, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, personal Digital Assistants (PDAs), and other terminal devices. The electronic device may also be a server or a network device in which a virtual machine is deployed, or may also be a management server that manages a plurality of servers or network devices in which virtual machines are deployed. In this case, the electronic device may specifically be a management device of the NFV management system.

Optionally, the resource allocation apparatus may also implement the function to be implemented by a Virtual Machine (VM) deployed on a physical machine.

It should be noted that the resource allocation apparatus 11 and the electronic device 12 may be independent devices or may be integrated in the same device, and this disclosure is not limited thereto.

When the resource allocation apparatus 11 and the electronic device 12 are integrated in the same device, the communication mode between the resource allocation apparatus 11 and the electronic device 12 is communication between internal modules of the device. In this case, the communication flow between the two is the same as the "communication flow between the resource allocation apparatus 11 and the electronic device 12 when they are independent of each other".

In the following embodiments provided in the present disclosure, the present application takes the resource allocation apparatus 11 and the electronic device 12 as an example and the same device.

For the sake of understanding, the resource allocation method provided in the present application is specifically described below with reference to the accompanying drawings.

Fig. 2 is a flowchart illustrating a resource allocation method according to an exemplary embodiment, where the method may be applied to an electronic device, and may also be applied to a resource allocation apparatus connected to the electronic device. Meanwhile, the method can also be applied to electronic equipment or equipment similar to the resource allocation device. In the following, the method is described by taking the method as an example, and as shown in fig. 2, the resource allocation method includes the following steps:

s201, deploying virtual services in the server.

As a possible implementation manner, in an initialization stage of a server, an electronic device deploys a virtual service in the server and acquires initial resource information of the virtual service.

The virtual service may be a routing function, a switching function, or a security function, as some examples.

Specifically, the electronic device may acquire the resource information of the server through an internet protocol multimedia subsystem private user identity (IMPI) protocol, a secure shell protocol (SSH), and other protocols. The resource information of the server includes management information of the server, central Processing Unit (CPU) information, memory information, disk information, and network card information.

The server management information includes a server identifier and an operating system version. The CPU information comprises the number of the CPU slots, the type of the CPU, the CPU dominant frequency, the number of the CPU cores and the number of the CPU threads. The memory information comprises the number of memory slots, the memory capacity and the memory working frequency. The disk information includes the number of disk slots and the disk capacity. The network card information includes the number of slot of the network card, the model of the network card, the number of port of the network card, and the address (MAC) of the port of the network card.

It should be noted that the resource information of the server may also be set by the operation and maintenance staff in advance in the electronic device by a manual entry method.

In one case, the resource information of the server may be stored in the electronic device in the following form:

server management information: { server ID, operating system version }.

CPU information: { CPU slot number, CPU model, CPU master frequency, CPU core number, CPU thread number }.

Memory information: { number of memory slots, memory capacity, memory operating frequency }.

Disk information: { number of disk slots, disk capacity }.

Network card information: { number of slot of network card, model of network card, number of port of network card, MAC of port of network card }.

Further, the electronic device virtualizes the CPU and the physical network card of the server, for example, virtualizes the CPU core of the server to be used by multiple virtual machine CPU (vCPU) cores, and virtualizes the physical network card port of the server to be used by multiple virtual network card ports.

It should be noted that, the physical network card port and the virtual network card port both have port MACs.

Subsequently, the electronic device completes the deployment of the virtual service in the server based on the virtualization technology through an automatic deployment mode or a manual setting mode by operation and maintenance personnel, and specifically includes server operations such as starting SR-IOV (single root I/virtualization) in a linux kernel, configuring a large-page memory of memory information, configuring vCPU core isolation and the like.

It should be noted that the virtualization technologies include keyboard, video, or mouse (KVM) virtualization, application container engine (Docker) virtualization, XEN virtualization, and the like.

In an implementation manner, taking a virtual service as a routing function as an example, in order to describe performance of the virtual service, in the embodiment of the present application, resource information of a server and resource information of the virtual service are in one-to-one correspondence, for example, CPU information of the server and CPU information of the virtual service are corresponding, memory information of the server and memory information of the virtual service are corresponding, and network card information of the server and memory information of the virtual service are corresponding.

Meanwhile, in the embodiment of the application, when the virtual service is a routing function, the resource information of the virtual service is also corresponding to the performance index of the virtual service. The performance indexes of the virtual service include bandwidth forwarding performance (BP), routing Performance (RP), and log storage performance (LP). The CPU information and the network card information of the virtual service correspond to bandwidth forwarding performance, the memory information of the virtual service corresponds to routing and session performance, and the disk information of the virtual service corresponds to log storage performance.

As can be understood, the electronic device may store the correspondence between the resource information of the server and the performance index of the virtual service in the electronic device based on the correspondence between the resource information and the performance index.

For example, in the CPU information of the server, { CPU slot number, CPU model, CPU master frequency, CPU core number, CPU thread number } may be marked as a bandwidth forwarding performance CBP of the virtual service CPU class: { CBP1, CBP2, CBP3, CBP4, CBP5}. In the network card information of the server, { network card slot number, network card model, network card port number, and network card port MAC } may be marked as a bandwidth forwarding performance resource NBP of the virtual service network card class: { NBP1, NBP2, NBP3, NBP4, NBP5}. In the memory information of the server, { memory slot number, memory capacity, memory operating frequency } may be marked as a routing and session performance resource RP: { RP, RP2, RP3}. In the disk information of the server, { disk slot number, disk capacity } may be marked as a log storage performance resource LP: { LP1, LP2}.

S202, determining initial service capability corresponding to initial resource information of the virtual service.

The initial resource information comprises an initial processor index for reflecting the performance of the processor, an initial memory index for reflecting the performance of the memory, and an initial network card index for reflecting the performance of the network card. The initial service capability includes an initial number of users and an initial bandwidth.

As a possible implementation manner, after the server deploys the virtual service, the electronic device may obtain initial resource information of the virtual service and determine an initial service capability corresponding to the initial resource information.

It should be noted that the initial processor index in the initial resource information may be manually entered in the electronic device by an operation and maintenance person in advance, or may be obtained by the electronic device based on the resource information of the server. For example, the electronic device may determine initial resource information of the virtual service as { RPmin, CBPmin, NBPmin } based on the resource information of the server. And RPmin is an initial memory index and comprises the minimum value of the memory capacity RP2 and the minimum value of the memory working frequency RP3 in the memory information of the server. CBPmin is an initial processor index and comprises the minimum value of a CPU core number CBP4 and the minimum value of a CPU thread number CBP5 in the CPU information of the server. NBPmin is an initial network card index and comprises the minimum value of the number NBP3 of network card ports in the network card information of the server.

It can be understood that, when the electronic device determines the initial resource information of the virtual service as the minimum value in the resource information of the server, it may be determined that the basic requirement of the user is satisfied.

Further, the electronic device determines, based on the initial resource information, a maximum number of users and a maximum bandwidth that the virtual service can bear in the case of the configuration of the initial resource information, determines the maximum number of users as an initial number of users, and determines the maximum bandwidth as an initial bandwidth.

S203, acquiring the service capability requirement of the target service.

The target service is a service to be used for virtual service, and the service capacity requirement comprises the number of target users and the target bandwidth.

As a possible implementation manner, when the user equipment of the user sends a request message of the virtual service to the electronic equipment for the target service, the electronic equipment receives the request message and acquires the service capability requirement of the user for the target service from the request message.

S204, adjusting the initial resource information based on the service capacity requirement and the initial service capacity to obtain target resource information.

As a possible implementation manner, the electronic device compares the initial user number in the initial service capability with the target user number in the service capability requirement, and adjusts the initial memory index in the initial resource information according to the comparison result to obtain the adjusted target memory index.

And the electronic equipment also compares the initial bandwidth in the initial service capacity with the target bandwidth in the service capacity requirement, and adjusts the initial network card index and the initial processor index in the initial resource information according to the comparison result to obtain the adjusted target network card index and the adjusted target processor index.

Further, the electronic device determines target resource information according to the target memory index, the target network card index and the target processor index. The target resource information comprises a target memory index, a target network card index and a target processor index.

The specific implementation manner of this step may refer to the subsequent description of the embodiment of the present application, and is not described herein again.

And S205, distributing resources for the virtual service based on the target resource information.

As a possible implementation manner, the electronic device controls the server to perform resource adjustment on the virtual service in the server based on the target resource information.

Based on the technical scheme provided by the embodiment of the application, the initial resource information of the virtual service is associated with the initial service capacity, so that after the service capacity requirement of the target service is obtained, the initial processor index, the initial memory index and the initial network card index in the initial resource information can be adjusted according to the target user number and the target bandwidth in the service capacity requirement and the initial user number and the initial bandwidth in the initial resource information, and the target resource information capable of meeting the service capacity requirement is obtained. Furthermore, the virtual service is subjected to resource allocation based on the target resource information, so that the virtual service after resource allocation can meet the service capacity requirement and avoid resource waste.

In some embodiments, in order to obtain the target resource information, as shown in fig. 3, S204 provided in the embodiments of the present application specifically includes the following steps:

s2041, determining a target memory index of the target service based on the number of the target users, the number of the initial users and the initial memory index.

As a possible implementation manner, the electronic device determines the target user number and the initial user number, and determines a target memory index according to the determination result and the initial memory index.

Specifically, when the number of target users is greater than the number of initial users, a first target amplification factor is determined based on the number of target users and the number of initial users, and the initial memory index is amplified based on the first target amplification factor to obtain a target memory index.

The first target amplification factor is greater than 1 and the first target amplification factor is positively correlated with the difference between the number of target users and the number of initial users.

And determining the initial memory index as a target memory index under the condition that the target user number is less than or equal to the initial user number.

In some cases, the target memory indicator satisfies the following formula one:

wherein, RP _s Is the target memory index, X is the target user number, X is the initial user number, round is the upward rounding,

is a first target magnification factor, P _min Is the initial memory index.

It can be understood that the larger the number of users, the larger the number of users assigned to the virtual server, and the larger the number of sessions, which are routes triggered by the virtual service.

S2042, determining target processor indexes of the target service based on the target bandwidth, the initial bandwidth and the initial processor indexes.

As a possible implementation manner, the electronic device determines the sizes of the target bandwidth and the initial bandwidth, and determines a target processor index according to the determination result and the initial processor index.

Specifically, when the target bandwidth is larger than the initial bandwidth, a second target amplification factor is determined based on the target bandwidth and the initial bandwidth, and the initial processor index is amplified based on the second target amplification factor to obtain the target processor index.

The second target amplification factor is greater than 1 and the second target amplification factor is positively correlated with the difference between the target bandwidth and the initial bandwidth.

In the event that the target bandwidth is less than or equal to the initial bandwidth, the initial processor metric is determined to be the target processor metric.

In some cases, the target processor metric satisfies the following equation two:

wherein, CBP _s Is the target processor index, Z is the target bandwidth, Z is the initial bandwidth, round is the rounding-up,

as a second target amplification factor, CBP _min Is the initial processor target.

It can be understood that the larger the bandwidth requirement of the user is, the larger the bandwidth forwarding rate allocated to the virtual service is, and the more CPU resources are required by the virtual service.

S2043, determining a target network card index of the target service based on the target bandwidth, the initial bandwidth and the initial network card index.

Specifically, under the condition that the target bandwidth is larger than the initial bandwidth, a second target amplification factor is determined based on the target bandwidth and the initial bandwidth, and the initial network card index is amplified based on the second target amplification factor to obtain the target network card index.

And determining the initial network card index as the target network card index under the condition that the target bandwidth is less than or equal to the initial bandwidth.

In some cases, the target processor metric satisfies the following formula three:

wherein NBP _s Is the target network card index, Z is the target bandwidth, Z degree is the initial bandwidth, round is the upward rounding,

for a second target amplification factor, NBP _min Is an index of an initial network card.

It can be understood that, the greater the bandwidth requirement of the user, the greater the bandwidth forwarding rate allocated to the virtual service is, and the more network card resources are required by the virtual service.

In addition, in the embodiment of the present application, the execution sequence of the above S2041, S2042, and S2043 is not limited.
