Description

Virtual network loading method and device

Technical field

The present embodiments relate to network technology more particularly to a kind of virtual network loading methods and device.

Background technique

On October 23rd, 2012, the large-scale operator of 13 telecommunications industries have issued network function virtualization (Network Function Virtualization, abbreviation NFV) white paper, it announces in European Telecommunication Standardization Association (European Telecommunications Standards Institute, abbreviation ETSI) set up NFV Industry Standard Organization (Industry Standard Group, abbreviation ISG).The initiation member of NFV ISG includes American Telephone and Telegraph Company (American Telephone&Telegraph, abbreviation ATT), Deutsche Telecom (Deutsche Telekom, abbreviation DT), Britain Telecom (British Telecom, abbreviation BT), Spanish Telephone Company (Telefonica), France Telecom (France Telecom, Abbreviation FT) etc. companies.The whole world, which has nearly various schools of thinkers company, at present becomes the member of NFV ISG tissue.

The purpose of operator establishment NFV ISG is the demand and relevant skill in order to define carrier network virtualization of function Art report, it is desirable to by using for reference the virtualization technology of information technology (Information Technology, abbreviation IT), general High-performance server, the network switch and storage equipment in realize subnetwork function.This needs network function with software side Formula is realized, and can be run on general server hardware, be can according to need and is migrated, instantiated, being deployed in network Different location, and do not need installation new equipment.Various types of network equipments such as server, router, storage equipment, are handed over It changes planes, can realize separation of software and hardware by NFV technology, they can be deployed in data center, network node or use In the man of family.

It sums up, NFV has 3 key characteristics: the software for defining network function is taken from general high performance hardware It is kept completely separate out in business device, storage equipment and the network switch；The independent modular characteristics of software and hardware component；Base Ground Remote Installation and management software equipment are fully automated in common hardware.

In NFV technology, network service (Network Service, a NS) example is by multiple virtual network functions (Virtualization Network Function, VNF) example composition.When needing to increase a VNF newly in NS example, need Carry out the load (On-boarding) of VNF.VNF On-boarding process refers to VNF program bag (VNF Package) Submit to network function virtualization composer (Network Functions Virtualization Orchestrator, NFVO), make NFVO that VNF Package is included in virtualization network function descriptor (Virtualised Infrastructure Manager Descriptor, VNFD) in catalogue.VNF Package is the files of VNF, the VNFD including VNF, virtually Machine mirror image (Virtual Machine image, VM image) file and some other component are such as used to check the archives The integrality of file and the component for proving its validity.After VNF On-boarding process carries out, VM image file It can be uploaded in virtualized infrastructure manager (Virtualised Infrastructure Manager, VIM), in this way After NFVO receives VNF instantiation request, the VM image file in VIM can be directly read, VNF instantiation can be saved Time.

But since in VNF framework, there may be multiple VIM for the management domain of an operation, and since NFVO is in example It just can be each virtualization deployment unit (Virtualization in VNF during executing resource allocation when changing VNF Deployment Unit, VDU) select the position disposed, the different deployed positions VIM that correspondence is different.Therefore in VNF During On-boarding, VNF image file can be uploaded in multiple possible VIM, can just make VNF example in this way After change, VM image file can be read in corresponding VIM, to save the time of VNF instantiation.

But since the size of VNF package is gigabit (gigabyte) magnitude, wherein VM image file is accounted for VM image file during VNF On-boarding is uploaded in multiple possible VIM, may be led by major part VM image file is caused to be uploaded in incoherent VIM, so as to generate in unnecessary operation and loading procedure The waste of memory space on network transmission resource and VIM.

In NFV MANO framework, there may be multiple VIM in a NFVO management domain, during VNF load, NFVO can not know that the VNF of load is corresponding with which VIM in instantiation process, therefore NFVO may be needed to multiple VIM (one As VM image file in VNF program bag is sent for all possible VIM sent of NFVO).In this way when NFVO receives the VNF's After instantiation request, since the VM image file of VNF has been stored in VIM, the time of VNF instantiation will be saved in this way.But It is the deployed position of only one determination of each VDU of VNF, also just for each of VNF during VNF instantiation VDU, all only one corresponding VIM, in this way after VNF is instantiated, the VM mirror image text of the VNF stored in some possible VIM Part will not be used.Since the size of VNF program bag is gigabyte magnitude, wherein VM image file accounts for major part, portion The VM image file for dividing VIM storage not used will waste a large amount of memory space, while NFVO sends VM mirror to multiple VIM As file will also generate some unnecessary operations.

To solve the above-mentioned problems, it is contemplated that the NSD loading procedure in NFV.NSD loading procedure and VNFD loading procedure are Two independent processes, and the VNF loading procedure for the VNF for including in NS is first completed in principle, then just carry out the load of NSD Process.Therefore, the transmission process of the VM image file in VNF program bag can be carried out again in NSD loading procedure, and mentioned The preceding VIM for selecting that virtual resource may be distributed for deployment VNF, so as to avoid NFVO from sending VM mirror image text to unrelated VIM The process of part, to solve the above problems.

Fig. 3 is the signalling diagram of NSD load, as shown in figure 3, needing to carry out NSD load in NFV MANO framework When, first in step S301, need to send NSD from transmitting terminal to NFVO, wherein transmitting terminal here is usually OSS, also Be operator an operation manager trigger manually NSD load；Transmitting terminal is also possible to other authorized third party entities, and such as the Triple net service provider.In step s 302, NFVO handles the NSD received, the VNF in including but not limited to inspection NS VNF program bag (VNF package) whether there is, check that some necessary elements whether there is, whether check has in VNFD External interface needed for description provides NS.

In step S303, when NFVO is verified NSD, NFVO sends the NSD to NS catalogue.In step S304 In, if NFVO sends NSD to NS catalogue, NSD is sent to transmitting terminal and loads success notification message.

Fig. 4 is the structural schematic diagram of NFVO embodiment one provided in an embodiment of the present invention, as shown in figure 4, the present embodiment NFVO includes:

Receiving module 41, for receiving the NSD of first network entity transmission.

Specifically, NFVO provided in this embodiment improves existing NSD load process, firstly, receiving module 41 receive the NSD that first network entity is sent, and triggering NSD loads process, and first network entity here is the transmission of NSD load End, first network entity are usually OSS, that is, an operation manager of operator triggers NSD load, first network entity manually It is also possible to other authorized third party entities, such as third party Internet Service Provider.

Processing module 42, for according to the restrictive condition in the VNFD in the restrictive condition and VNF catalogue in the NSD, Selection can be when disposing VNF to the candidate VIM of VNF distribution virtual resource.

Specifically, the present embodiment is the load process of NSD, since a NS is made of multiple VNF, is loaded in NSD Before, the loading procedure for needing to carry out each VNF in NS just can be carried out the load of NSD after each VNF in NS completes load.Cause This, before receiving module 41 receives the NSD that first network entity is sent in the present embodiment, NFVO provided in this embodiment is also answered The load process of each VNF in NS is carried out.In the load process of VNF, NFVO can receive the VM of the VNF in VNF program bag Image file, alternatively, NFVO receive can be only VNF the corresponding uniform resource locator (Uniform of VM image file Resource Locator, URL), the corresponding URL of VM image file of VNF illustrates the corresponding downloading of VM image file of VNF Address.NFVO can deposit the corresponding URL of VM image file of the VNF image file or VNF for loading the VNF received in process Storage is got up.When NFVO carries out the NSD loading procedure in the present embodiment, when receiving module 41 receives NSD, processing module 42 will According to the restrictive condition in NSD, and from the restrictive condition in the VNFD read in VNF catalogue, selection can be when disposing VNF To the candidate VIM of VNF distribution virtual resource.

One VNF may include multiple VNF components (VNFC, VNF Component), according to VNF deployment requirements and limitation Condition, the corresponding VDU of these VNFC may need across VIM deployment, at this time the corresponding VM image file of difference VDU or VM mirror image text The corresponding URL of part needs to upload to different VIM.The corresponding VDU of these VNFC may also need to be deployed in a VIM management domain Inside, the corresponding VM image file of difference VDU or the corresponding URL of VM image file need to upload on identical VIM at this time.No Under the conditions of which kind of pipe is, the candidate VIM that can distribute virtual resource for each VNFC selection can be one, be also possible to more It is a.

Wherein, the restrictive condition in the restrictive condition and VNFD in NSD defines that position, VNF that NS to be disposed are wanted The relationship etc. of each VNF deployed position in the position of deployment, NS, NFVO finally determine the portion of VNF according to above-mentioned various positions relationship Affix one's name to position, the i.e. corresponding VIM of VNF.After NFVO has determined VNF corresponding VIM, the VM image file of as VNF or the VM of VNF The corresponding URL of image file selects corresponding VIM.

Sending module 43, the VM image file of the VNF for that will store or the corresponding URL of the VM image file of VNF are sent To the candidate VIM；Notify NS catalogue that the NSD is added；NSD load success notification is sent to the first network entity to disappear Breath.

Specifically, after processing module 42 has determined candidate VIM, sending module 43 can send to corresponding VIM and store VM image file or the corresponding URL of VM image file.Subsequent sending module 43 also sends a notification message to NS catalogue, notifies NS The NSD is added in catalogue, sends NSD to first network entity and loads success notification message, completes NSD and loads process.If sending mould That block 43 is sent to VIM is the corresponding URL of VM image file, then after VIM receives the URL, under the corresponding address the URL Carry corresponding VM image file.

Since NFVO provided in this embodiment is to be according to the restrictive condition in NSD and VNFD in NSD load process It is just corresponding to the VM image file of selected VIM transmission VNF or the VM image file of VNF after VNF has selected corresponding VIM URL, therefore the VM image file of VNF will not be sent to unrelated VIM, to save the capacity of VIM and will not generate Additional transmission operation.

It should be noted that NFVO provided in this embodiment only improves NSD load process, wherein defaulting NFVO has preserved the VM image file or the corresponding URL of VM image file of VNF, but the VM image file or VM mirror image of VNF The corresponding URL of file, which can be, is sent to NFVO's by other any modes before NSD loads process.One of which can The mode of choosing is during VNF load, and NFVO saves the VM image file or the corresponding URL of VM image file of VNF.

NFVO provided in this embodiment, by being loaded in process in NSD, by NFVO according in NSD and VNF catalogue in VNFD Restrictive condition, selection can when dispose VNF to VNF distribute virtual resource candidate VIM, then again by the VNF's of storage The corresponding URL of the VM image file of VM image file or VNF is sent to the candidate VIM, then terminates NSD load process, keeps away Exempt from the VM image file of VNF being sent to unrelated VIM, has saved depositing for the network transmission resource and VIM in loading procedure Space is stored up, and avoids the operation needed for unrelated VIM transmission VM image file.

Fig. 5 is the structural schematic diagram for the NFVO embodiment two that inventive embodiments provide, as shown in figure 5, the present embodiment NFVO is on the basis of fig. 4, further includes: memory module 44.

Receiving module 41, for before receiving the NSD that first network entity is sent, receiving the first network entity hair The VNF program bag sent.

Specifically, NFVO provided in this embodiment improves existing VNF load process, for shown in Fig. 4 The NFVO of embodiment execute before NSD load, for saving the VM mirror image of VNF in NFVO in the loading procedure of VNF File or the corresponding URL of VM image file.

Firstly, the receiving module 41 in NFVO receives the VNF program bag that first network entity is sent, triggering VNF load stream Journey, first network entity here are the triggering end of NSD load, and first network entity is usually OSS, that is, the behaviour of operator Make administrator and trigger NSD load manually, first network entity is also possible to other authorized third party entities, such as third party's net Network service provider.

Sending module 43, for notifying VNF catalogue that the VNFD in the VNF program bag is added.

Specifically, after receiving module 41 receives VNF program bag, sending module 43 needs to send VNF journey to VNF catalogue The VNFD in the VNF program bag is added in VNFD in sequence packet, notice VNF catalogue.

Memory module 44, for storing the VM image file of the VNF in the VNF program bag or the VM image file of VNF Corresponding URL.

Specifically, in VNF loading procedure, NFVO can not also know the corresponding VIM of VNF, if therefore NFVO needs at this time The VM image file of VNF is sent to VIM, then NFVO is in order to guarantee the efficiency of VNF instantiation process, it may be necessary to multiple VIM Send the VM image file of VNF in VNF program bag.But it can thus generate additional operation and VM image file may be sent out It send to incoherent VIM.Therefore, memory module 44 is arranged in NFVO to deposit after receiving module 41 receives VNF program bag Storing up module 44 is the corresponding URL of VM image file for storing the VM image file or VNF of the VNF in VNF program bag.It is stored The corresponding URL of VM image file of the VM image file or VNF of VNF will be in NSD loading procedure, when NFVO has determined VNF pairs After the VIM answered, then to VIM transmission, so as to avoid extra operation and avoid for the VM image file of VNF being sent to not Relevant VIM.

Sending module 43 is also used to send VNF program bag load success notification message to first network entity.

Specifically, memory module 44 stores the VM image file of the VNF in VNF program bag or the VM image file of VNF After corresponding URL, sending module 43 can send VNF program bag to first network entity and load success notification message, complete VNF Load process.

NFVO provided in this embodiment, by loading in process in VNF, NFVO stores the VM image file or VNF of VNF The corresponding URL of VM image file is avoided the VM image file of VNF being sent to unrelated VIM without sending to VIM, is saved The memory space of network transmission resource and VIM in loading procedure, and avoid to unrelated VIM and send VM image file Required operation.

Further, in the embodiment shown in fig. 5, processing module 42 are also used to store the VNF journey in memory module 44 Before the corresponding URL of VM image file of the VM image file or VNF of VNF in sequence packet, the VNF program bag is checked；Storage Module 44, if specifically for, including the VM image file of VNF, being stored in the VNF program bag in the VNF program bag The VM image file of VNF；If including the corresponding URL of VM image file of VNF in the VNF program bag, the VNF journey is stored The corresponding URL of VM image file of VNF in sequence packet.

Specifically, due to may include the VM image file of VNF in the received VNF program bag of receiving module 41, it is also possible to The corresponding URL of VM image file including VNF.Therefore after receiving module 41 receives VNF program bag, processing module 42 needs Check the VNF program bag received, if in VNF program bag including the image file of VNF, memory module 44 stores the mirror of VNF As file.If including the corresponding URL of image file of VNF in VNF program bag, memory module 44 stores the image file of VNF Corresponding URL.

Another implementation of the NFVO of embodiment illustrated in fig. 4 offer, in this implementation, NFVO are provided In VNF load process, it is necessary first to receive the corresponding URL of VM image file including VNF, then be sent to multiple VIM The URL, but notice VIM does not download the corresponding VM image file of the URL.NFVO in NSD load process, when according to NSD and After restrictive condition in VNFD has determined the corresponding VIM of VNF, the URL of the VM image file of corresponding VIM downloading VNF is reinformed Corresponding VM image file.Although in this implementation, in VNF loading procedure, NFVO also can send URL to multiple VIM File, but the process of VIM downloading VM image file is still in NSD load process, ability after VNF corresponding VIM has been determined It carries out.Since the memory space that URL file occupies is minimum, this implementation equally can be to avoid excessive VM mirror image File is sent to unrelated VIM, to save the memory space of VIM.

In this implementation, receiving module 41, for receiving the NSD of first network entity transmission；Processing module 42, For according to the restrictive condition in the VNFD in the restrictive condition and VNF catalogue in the NSD, selection can be when to dispose VNF To the candidate VIM of VNF distribution virtual resource；Sending module 43, for notifying the candidate VIM according to the VM image file pair The URL downloading VM image file answered；Notify NS catalogue that the NSD is added；NSD is sent to the first network entity to load successfully Notification message.

Specifically, this implementation equally improves existing NSD load process, firstly, receiving module 41 The NSD that first network entity is sent is received, triggering NSD loads process, and first network entity here is the triggering of NSD load End, first network entity are usually OSS, that is, an operation manager of operator triggers NSD load, first network entity manually It is also possible to other authorized third party entities, such as third party Internet Service Provider.Then, if NFVO has been issued to VIM The corresponding URL of VM image file of VNF, the then restrictive condition in NSD that processing module 42 is received according to receiving module 41 With from the restrictive condition in the VNFD read in VNF catalogue, selection can be when disposing VNF to the time of VNF distribution virtual resource The VIM is selected to be.Last sending module 43 just notifies the candidate VIM to download VM mirror image according to the corresponding URL of the VM image file File；And notify NS catalogue that the NSD is added；NSD is sent to the first network entity and loads success notification message, is completed NSD loads process.It should be noted that the NFVO that this implementation provides only improves NSD load process, wherein Default NFVO has had sent the corresponding URL of VM image file of VNF to VIM, but the corresponding URL of VM image file of VNF can By be NSD load process before by other it is any in a manner of be sent to VIM.One of optional mode is in VNF During load, NFVO has sent the corresponding URL of VM image file of VNF to VIM.

During VNF load provided below, NFVO has sent the tool of the corresponding URL of VM image file of VNF to VIM Body implementation.This implementation improves VNF load process, firstly, receiving module 41, it is real to receive first network The VNF program bag that body is sent.Then the VNFD in the VNF program bag is added in sending module 43, notice VNF catalogue；And it will The corresponding URL of VM image file of VNF in the VNF program bag is sent at least one VIM；Finally to first network entity It sends VNF program bag and loads success notification message, terminate VNF and load process.In this VNF load process, receiving module 41 Needed in the VNF program bag received include VNF the corresponding URL of VM image file, if that include in VNF program bag is VNF VM image file, then cannot use this process.The corresponding URL of VM image file of VNF can be sent to by sending module 43 All possible VIM, i.e., all VIM being connect with NFVO.In this way in NSD load process, it is ensured that all possible VIM In have the corresponding URL of VM image file of VNF.

Further, embodiment shown in Fig. 5 or above-mentioned another kind VNF are loaded in process, and processing module 42 is also used to Sending module 43 notifies the VNF catalogue to be added before the VNFD in the VNF program bag, verifies the VNF program bag, processing Module 42 verifies the VNF program bag, include the following steps at least one of: processing module 42 checks the VNF program bag In necessary element whether there is, processing module 42 using in the VNFD in the VNF program bag list and certification authentication institute State the authenticity and reliability of VNFD；Sending module 43, if being checked specifically for processing module 42 necessary in the VNF program bag Element exist, if processing module 42 using in the VNFD in the VNF program bag list and certification authentication described in VNFD has authenticity and reliability, then notifies the VNF catalogue that the VNFD in the VNF program bag is added.
