In order to solve in business demand updates faster application scenarios, the VNF cited in frequent manual modification NS templates
The problem of template identification, the embodiment of the present application provides a kind of method of network service template generation, as shown in Fig. 2 this method bag
Include：
Step 201, NFVO receive the NS Disposition Instructions that Deployment Manager is sent.
It should be noted that NFVO after NS Disposition Instructions are received, can solve to the NS Disposition Instructions of reception
Analysis, to obtain the demand configuration information at least one VNF network elements to be disposed that NS Disposition Instructions include.Wherein, it is single to wait to dispose
Functional requirement information and single to be disposed VNF network element of the demand configuration information of VNF network elements including single VNF network elements to be disposed
Performance requirement information.
For example, after NFVO parses to NS Disposition Instructions, the demand for obtaining NS deployment is:Needed in on-premise network is treated
Two VNF network elements, i.e. VNF1, VNF2 are established, also, VNF1 demand configuration information is { functional requirement information：Registration, performance
Demand information：Time delay is less than 15ms }, VNF2 demand configuration information is { functional requirement information：Carrying is established, performance requirement letter
Breath：Carry the data volume of at least 600,000 user terminals }, i.e. VNF1 provides registering functional, and its response delay to external signal
Less than 15ms, VNF2 provides the function that carrying is established, and can carry the data volume of at least 600,000 user terminals.
Step 202, NFVO treat in on-premise network each VNF network elements to be disposed according to what the NS Disposition Instructions of reception included
Demand configuration information, determination target VNF network element groups in VNF network elements are disposed in the whole of on-premise network.
Wherein, target VNF network elements group includes at least one VNF network elements, and single in target VNF network element groups has disposed
For the configuration information of VNF network elements with treating that the demand configuration information of single VNF network elements to be disposed in on-premise network matches, demand matches somebody with somebody confidence
Cease for indicating the configuration needed for single VNF network elements to be disposed, configuration information is used to indicating single to have disposed matching somebody with somebody for VNF network elements
Put, the whole of on-premise network has been disposed VNF network elements and succeeded in registration in NFVO.
It should be noted that before the method flow shown in Fig. 2 is performed, the whole in on-premise network has disposed VNF
Network element need to be registered in NFVO.As a kind of possible implementation, NFVO, which is received, has each disposed the transmission of VNF network elements
Registration request, the single registration request for having disposed VNF network elements include the single configuration information for having disposed VNF network elements, the configuration
Information includes：This disposed VNF network elements function information, this disposed VNF network elements performance information, this disposed VNF network elements
The virtual network function manager (Virtual Network Function Manager, VNFM) belonged to and this disposed
The resource requirement information of VNF network elements.Then, in response to the registration request, NFVO this has been disposed VNF network elements function information,
The configuration informations such as performance information are stored.As a kind of possible implementation, NFVO stored in a manner of form it is each
Dispose the configuration information of VNF network elements.For example, after in response to having disposed the registration request of VNF network elements, the portion of NFVO storages
The configuration information for affixing one's name to VNF network elements is as shown in table 1：
Table 1
It should be noted that in table 1, ID can be distributed for each VNF network elements of having disposed by NFVO.
In addition, the configuration information for having disposed VNF network elements also includes the resource requirement information for having disposed VNF network elements, such as the institute of table 2
Show, to dispose each information for having disposed resource needed for VNF network elements：
Table 2
In addition, in order to improve the security of Network, NFVO can also dispose the transmission of VNF network elements receiving one
After registration request, the legitimacy for having disposed VNF network elements is veritified, however, it is determined that this has been disposed VNF network elements and has disposed VNF to be legal
Network element, then VNF network elements are disposed to this and have sent registration request response, to cause this has disposed VNF network elements to send this to NFVO
Dispose the configuration information of VNF network elements.
Illustrate below and the method for choosing target VNF network element groups is illustrated, the VNF nets to be disposed that NS Disposition Instructions include
Member demand configuration information be：VNF1 demand configuration information is { functional requirement information：Registration, performance requirement information：Time delay is low
In 15ms }, VNF2 demand configuration information is { functional requirement information：Carrying is established, performance requirement information：Carrying at least 600,000
The data volume of user terminal }.
As shown in table 1,2, disposed each in VNF network elements, VNF_AD can provide registration, the function of authentication, and its
Response delay to external signal is 10ms, it is seen then that VNF_AD configuration information matches with VNF1 demand configuration information, VNF_
BC can provide registration, the function of authentication, and its response delay to external signal be 12ms, VNF_BC configuration information and
VNF1 demand configuration information matching, so, VNF_AD, VNF_BC are satisfied by VNF1 deployment requirements；VNF_LD can be provided
The function of establishing is carried, and the carrying of VNF_LD foundation can carry the data volume of 1,000,000 user terminals, so VNF_LD meets
VNF2 deployment requirements.Therefore, NFVO determines two candidate's VNF network element groups, i.e. VNF network elements group 1 in on-premise network：
{ VNF_AD, VNF_LD }, VNF network elements group 2：{ VNF_BC, VNF_LD }.
It should be noted that in the embodiment of the present application, it is more excellent in order to further choose performance in candidate's VNF network element groups
Target VNF network element groups, NFVO can choose target VNF network elements according to preset strategy in above-mentioned candidate's VNF network element groups
Group.
Wherein, preset strategy can be that the minimum candidate's VNF network element groups of resource occupation in each candidate VNF network element groups is true
It is set to target VNF network element groups, or the optimal candidate's VNF network element groups of combination property in each candidate VNF network element groups is true
It is set to target VNF network element groups.
It is assumed that preset strategy is using the optimal candidate's VNF network element groups of combination property in each candidate VNF network element groups as mesh
VNF network element groups are marked, then NFVO calculates the resource comprehensive demand of each candidate VNF network element groups.Wherein, VNF network elements group 1：{VNF_
AD, VNF_LD } resource comprehensive demand be { CPU：10+8=18, internal memory：64+64=128, hard disk：100+60=160 }, VNF
Network element group 2：The resource comprehensive demand of { VNF_BC, VNF_LD } is { CPU：12+8=20, internal memory：64+64=128, hard disk：60+
60=120 }.Here it is respectively 0.7,0.2,0.1 to set CPU, internal memory, the calculating weight of hard disk, then the resource of VNF network elements group 1
Integration requirement is 18*0.7+128*0.2+160*0.1=54.2, and the resource comprehensive demand of VNF network elements group 2 is 20*0.7+128*
0.2+120*0.1=51.6.So the resource comprehensive demand of VNF network elements group 2 is less, VNF network elements group 2 is chosen as target VNF
Network element group.
Step 203, NFVO generate NS templates according to each configuration information for having disposed VNF network elements in target VNF network element groups.
Specifically, NFVO is according to each function information, performance information for having disposed VNF network elements etc. in target VNF network element groups
The configuration information generation NS templates of VNF network elements are disposed.With reference to the example above, target VNF network elements group is VNF network elements group 2, VNF
In network element group 2, VNF_BC configuration information is { function information：Registration, authentication, performance information：Time delay 12ms, VNF_BC ownership
VNFM2, required CPU：12, required internal memory：64GB, required hard disk：60GB }, VNF_LD configuration information is { function information：
Carrying is established, performance information：The data volume of the user terminal of bearing capacity 1,000,000, VNF_LD ownership VNFM1, required CPU：8, institute
Need internal memory：64GB, required hard disk：60GB}.Then, NFVO generates NS templates according to VNF_BC and VNF_LD configuration information.Show
Example property, NFVO writes VNF_BC and VNF_LD configuration information in NS templates, to obtain the final NS of the embodiment of the present application
Template.
It should be noted that NS templates can also include VNF deployment strategy, deployment strategy includes compatibility strategy, if
It is affinity relation that compatibility strategy, which characterizes two VNF, then in subsequent deployment NS, the two VNF can be deployed in same computer room
In interior either same frame or on same server, if it is anti-affinity relation that compatibility strategy, which characterizes two VNF, follow-up
When NS is disposed, the two VNF can not be deployed in same computer room in either same frame or on same server.
The method for the network service template generation that the embodiment of the present application provides, in deployment NS application scenarios, NFVO connects
After the NS Disposition Instructions for receiving Deployment Manager transmission, each wait to dispose in on-premise network according to treating of including of NS Disposition Instructions
The demand configuration information of VNF network elements, determination target VNF network element groups in VNF network elements are disposed in the whole of on-premise network.Due to
Need of the single configuration information for having disposed VNF network elements with treating single VNF network elements to be disposed in on-premise network in target VNF network element groups
Configuration information is asked to match, so the demand disposed VNF network elements and disclosure satisfy that NS deployment in target VNF network element groups.Then,
NFVO generates NS templates according to the configuration information for having disposed VNF network elements for meeting NS deployment requirements.It can be seen that in the embodiment of the present application
In, even if business demand renewal is very fast, without the VNF template identifications cited in frequent manual modification NS templates.
In addition, VNF templates corresponding with needing to previously generate each business in the prior art, then according to current business need
Ask, the VNF template identifications that reference is manually write in NS templates are compared, and in the embodiment of the present application, obtain target VNF network element groups
In each configuration information for having disposed VNF network elements, and NS templates are generated according to the configuration information of acquisition, it is therefore not necessary to generate every
VNF templates corresponding to individual business.
In another implementation of the embodiment of the present application, as shown in figure 3, in step 203, NFVO according to target VNF
In network element group after each configuration information generation NS templates for having disposed VNF network elements, step 301 and step 302 can also carry out.
Step 301, NFVO modify according to the current network demand for treating on-premise network to network configuration information, wherein,
Network configuration information is the information related to network configuration in NS templates, and network configuration information includes VNF network elements to be disposed
Topological connection relation between IP address, each two VNF network elements to be disposed.
It should be noted that before step 301, NFVO need to be new VNF network elements to be disposed according to the NS templates of generation
Distribute resource.With reference to the example above, the NS templates of generation include VNF_BC and VNF_LD configuration information, wherein, VNF_BC's
Configuration information is { function information：Registration, authentication, performance information：Time delay 12ms, VNF_BC ownership VNFM2, required CPU：12,
Required internal memory：64GB, required hard disk：60GB }, VNF_LD configuration information is { function information：Carrying is established, performance information：Hold
Carry the data volume of 1,000,000 user terminals, VNF_LD ownership VNFM1, required CPU：8, required internal memory：64GB, required hard disk：
60GB }, NFVO is that VNF1 to be disposed distributes the resources such as CPU, internal memory, hard disk according to above-mentioned VNF_BC configuration information, according to
Above-mentioned VNF_LD configuration information is the resources such as VNF2 distribution CPU to be disposed, internal memory, hard disk.Wherein, NFVO distributes for VNF1
Resource be { CPU：12, internal memory：64GB, hard disk：60GB}.Then NFVO notifies VNF1 to be disposed ownership VNFM, i.e.,
VNFM2 is instantiated and started to VNF1, meanwhile, NFVO notices VNFM1 is instantiated and started to VNF2.Wherein,
VNFM1, VNFM2 can be the functional unit integrated in Deployment Manager, or independent functional unit, the application are implemented
Example is not limited to this.
It is understood that the network configuration information of acquiescence is also included in NS templates, for example, according to NS templates, business field
Jing Zhongxu deployment 5 VNF as shown in Figure 4, and the network information given tacit consent to is configured to：VNF1 IP address is IP1, VNF2 IP
Address is that IP2, VNF3 IP address are that IP3, VNF4 IP address is that IP4, VNF5 IP address is IP5, and VNF1 with
Have link connection between VNF2, there is link connection between VNF2 and VNF3, there is link connection between VNF3 and VNF5, VNF1 with
There is link connection between VNF5, have link connection between VNF3 and VNF4, and the topology between each two VNF network elements to be disposed is even
The relation of connecing can be expressed as { VNF1-VNF2, VNF2-VNF3, VNF3-VNF5, VNF1-VNF5, VNF3-VNF4 }.
But the network configuration of above-mentioned acquiescence is likely to that current NS deployment requirements can not be met, so, NFVO can be right
Default network configuration information in NS templates is modified, and has adapted to current NS deployment requirements.Exemplarily, changed through NFVO
Afterwards, still need to dispose 5 VNF network elements in current business scene, the topological connection relation between each two VNF network elements dispose such as figure
Shown in 5, i.e., amended network configuration information is：VNF1 IP address is that IP1, VNF2 IP address are IP2, VNF3 IP
Location is that IP3, VNF4 IP address are that IP4, VNF5 IP address is IP5, and has link connection between VNF2 and VNF3, VNF3
Have link connection between VNF5, there is link connection between VNF1 and VNF5, there is link connection between VNF3 and VNF4, VNF4 with
There is link connection between VNF5.
Step 302, NFVO send amended network configuration information to synergist, to indicate that synergist treats on-premise network
Carry out routing configuration so that treat mutual reachable between each two VNF network elements dispose in on-premise network.
Wherein, synergist can be software defined network (Software Defined Network, SDN) synergist, SDN
Synergist can be the One function component in NFVO, or independent functional unit, the embodiment of the present application are not entered to this
Row limitation.
It should be noted that the routing configuration equipment higher as rank, synergist can treat on-premise network and enter walking along the street
By configuring, amended network configuration information can also be handed down to the other each controller of next stage by synergist, so as to each
Controller is responsible for the routing configuration of self-management VNF network elements.For example, the controller A management such as VNF1 to VNF3 in Fig. 5, control
Device B manages VNF4 and VNF5, then amended network configuration information can be handed down to controller A and controller B by synergist, then
Routing configuration is carried out to the interchanger of each Self management, router and VNF network elements by controller A and controller B, and then causes every two
Path is reachable between individual VNF network elements to be disposed.
Wherein, controller noted above can be SDN controllers, and the embodiment of the present application is not limited to this.
It is understood that after the routing configuration in treating on-premise network is completed, road can be sent from synergist to NFVO
The instruction completed by configuration, to cause NFVO to being verified with the network postponed, if being verified, network design success.
Corresponding to the flow of the above method, the embodiment of the present application provides a kind of network equipment, as shown in fig. 6, the network is set
It is standby to include：Memory 601, processor 602, transceiver 603, bus 604.
