Description

A kind of virtual network service deployment method and apparatus

Technical field

The present invention relates to network function technical field of virtualization, particularly relate to a kind of virtual network service deployment method and apparatus.

Background technology

Along with the development of Internet technology, the network that Virtual network operator is disposed is made up of diversified physical equipment.Different Networks needs different physical equipments, the Network that often exploitation one is new, in requisition for the physical equipment increasing newtype, but determine that the locus of newly-increased physical equipment and supply line become more and more difficult along with the increase of Network, so just seriously inhibit the deployment of new Network.

In order to solve above-mentioned Problems existing, propose network function virtual (NFV, Network Functions Virtualization), wherein, network function is virtual refers to operational network function on common physical equipment, and common form is: dispose virtual machine on the physical devices.

The NFV framework of current proposition contains service operation and management platform (OSS/BSS, Operation-Support System/Business Support System), service, virtualized network function and infrastructure device description unit (Service, VNF(Virtual Network Function) and Infrastructure Description), network function virtual management and layout platform (NFV Managementand Orchestration).

Particularly, OSS/BSS, except conventional management function, completes the operation and maintenance to network alternately for virtualization applications and Orchestrator.

Service, virtualized network function and infrastructure device description unit contain NS information model description template (NSD, NS Descriptor), VNF information model description template (VNFD, VNF Descriptor), virtual link description template (VLD, Virtual Link Descriptor), VNF Software Mirroring etc.

Wherein, NSD is by operator or integrator's planning network information, and this network information comprises and uses VNF example list that VNFD list, Network (NS, the Network Service) capacity of support and different N S capacity are corresponding and VLD list etc.

VNFD is by virtualized network function (VNF, Virtual Network Function) provider provides, contain VNF function, the virtual machine list needed in capabilities-list that VNF supports, different capabilities situation, the deployment software information of each virtual machine and outer outbound port etc.

VLD is for describing VNF example link requirements, and the two ends of link are represented by the tie point (CP, Connect Point) (such as: VNF_CP identifies) of VNF example types.

Orchestrator(layout platform) be NS life cycle management (such as: deployment/dilatation/roll off the production line) at least one data center, the layout of NFVI resource, NSD is mainly utilized to complete the network planning to NS, decomposite the demand of each VNF, and the capacity requirement of VNFD and VNF is handed down to VNF management system (VNFM, NFV Manager), then the deployment of VNF is completed by VNFM.

Particularly, Orchestrator, when receiving the NS instantiate request that OSS sends, according to the NSD index carried in NS instantiate request, obtains the NSD that NSD index is corresponding, and obtain the VNF example list needing instantiation from the NSD obtained; Again according to the VNF example in the VNF example list obtained, select the VNFD index meeting this VNF example, and utilize the VNFD that VNFD index is corresponding to carry out instantiation operation.

Wherein, in NSD, the capacity being deployed in the different VNF examples of same NS is identical with NS capacity.

As can be seen here, when Orchestrator disposes VNF instantiation, Orchestrator, according to NS total capacity, disposes the capacity (capacity namely disposing each VNF example is identical with NS total capacity) of each VNF example, there is the problem of the wasting of resources.

As can be seen from Table 1, once determine to adopt which NS deployment parameters, the scale parameter of VNF example types and VNFD index corresponding to VNF example types and VNF example can be determined.

Wherein, VNF example corresponding to same VNF example types can be one, can also be multiple; When the VNF example that same VNF example types is corresponding is multiple VNF example, for multiple VNF examples that same VNF example types is corresponding, the VNFD index that different VNF example is corresponding can be identical, also can be different; When multiple VNF examples that same VNF example types is corresponding, and VNFD index corresponding to different VNF example identical time, VNF example corresponding to identical VNFD index can be distinguished by example number, such as: corresponding two the VNF examples of 2*VNF C example, the VNDF index that these two VNF examples are corresponding is VNFD4, now can be distinguished by No_4 and No_5 for corresponding two the VNF examples of 2*VNF C example.

At least two the NS deployment parameters (the VNFD packets of information that wherein, VNF example types is corresponding is containing the VNFD index in public Common information in Vendor mark and NSD) comprised in a NSD template as shown in table 2:

Table 2

As can be seen from Table 2, once determine to adopt which NS deployment parameters, VNF example types and Vendor mark corresponding to VNF example types and the scale parameter of VNF example can be determined.

Wherein, VNF example corresponding to same VNF example types can be one, can also be multiple; When the VNF example that same VNF example types is corresponding is multiple VNF example, for multiple VNF examples that same VNF example types is corresponding, the Vendor mark that different VNF example is corresponding can be identical, also can be different; When multiple VNF examples that same VNF example types is corresponding, and different VNF example corresponding Vendor mark identical time, VNF example corresponding to identical VNFD index can be distinguished by example number, such as: corresponding two the VNF examples of 2*VNF C example, the Vendor that each VNF example is corresponding is designated Vendor D, now can be distinguished by No_4 and No_5 for corresponding two the VNF examples of 2*VNF C example.

Step 202:Orchestrator, from the described NSD information obtained, determines to meet the VNF example of the capacity requirement of the NS to be instantiated carried in the NS instantiate request received.

In step 202., suppose that the capacity of the NS to be instantiated carried in the NS instantiate request received is 500Kcaps, the NS deployment parameters identical with the capacity 500Kcaps of NS to be instantiated is searched, i.e. NS deployment parameters 1 in the described NSD information so obtained from step 101.

As can be seen here, the instantiation of setting up at least is needed to contain 1*VNF A example, 2*VNF B example and 2*VNF C example in NS deployment parameters 1.

Particularly, from the described NSD information obtained, the NS deployment parameters of the capacity requirement of the NS to be instantiated carried in the NS instantiate request meeting and receive is searched.

Particularly, carry the mark of VNF example corresponding to the VNF example types of carrying out instantiation in described Network NS instantiate request, determine the VNF example not yet carrying out instantiation, comprising:

Compare carrying the VNF example types of carrying out instantiation in each the VNF example types comprised in the NS deployment parameters found and described Network NS instantiate request.

That is there is the VNF example of instantiation in the instantiation that the needs comprised in deployment parameters 1 are set up, no longer can carry out instantiation so in embodiments of the present invention.

Step 203:Orchestrator, according to the capacity of the scale parameter of the VNF example determined and described NS to be instantiated, calculates the capacity of the described VNF example determined.

In step 203, suppose the capacity of the VNF example calculating NO_1 corresponding to 1*VNF A example, the scale parameter so finding the VNF example of the NO_1 that 1*VNF A example is corresponding in VNF deployment parameters 1 from the NSD template that step 202 obtains is 100%, again according to the capacity 500Kcaps of NS to be instantiated, the capacity calculating the VNF example of NO_1 corresponding to 1*VNF A example is 500Kcaps.
