Wherein, it should be noted that for each VNFC in the same VNF due to function difference, importance is also different.Cause And in the concurrent multiple life cycle events of processing, the life cycle events for the VNFC for answering priority processing important prolong to prevent it Cause to malfunction late.The processing method of life cycle events provided in an embodiment of the present invention, according to the difference of the importance of VNFC Corresponding priority is defined for it, in this way, when multiple life cycle events are concurrent, the higher Life Cycle of priority processing priority Phase event can prevent important life cycle events to be delayed by, and avoid processing mistake.

Specifically, can be by extending virtual network function descriptor (Virtualized Network Function Descriptor, VNFD) in VDU project VNFC priority is defined, such as at VDU increase VNFC project, that is, pass through VNFD:VDU:VNFC realizes the definition to VNFC priority；New project can also be increased in VNFD to carry out VNFC priority Definition increases VNFC_priority project such as in VNFD.In addition, when being defined to VNFC priority, in addition to indicating Except the priority of VNFC, it is also necessary to indicate the mark (IDentity, ID) and the priority scope of application of VNFC.Wherein, ID is fixed It is adopted consistent with existing standard；Priority can be indicated by number, character or other modes；The priority scope of application is in order into one Step refines the parameter that priority is defined and introduced, and possible values includes Host, VNF etc..When being appointed as Host, show that this is preferential Grade is only applicable to priority ratio between the different VNFC on the same physical server compared with and being not particularly suited for different physical services The comparison of priority between VNFC on device；When being appointed as VNF, then it represents that the priority is suitable for owning under the same VNF VNFC priority ratio compared with the case where.By specifying the scope of application, administrator or VNF provider can specify place in thinner granularity Priority is managed, thus the situation that reply is more special.

In general, the different types of life cycle events of difference VNFC will not influence each other in the same VNF, therefore not It needs stringent to execute sequence.But under certain special screnes, certain form of life cycle events is needed preferentially to execute.Example Such as, when needing Quick thread to service, the priority of instantiate, scaleout/up life cycle events is higher than Terminate, scale in/down life cycle events；And when resource anxiety, or difference VNFC belong to same physics clothes Be engaged in device, occur when resource re-allocation, terminate, scale in/down life cycle events priority will height In instantiate, scale out/up life cycle events.For this purpose, life cycle events provided in an embodiment of the present invention Processing method can meet the needs of special screne, avoid by holding by the priority different to different event type definitions Row sequence causes processing mistake.

Similarly, can be by defining event type priority in VNFD:lifecycle_event, it can also be by adding The new projects of such as VNFD:lifecycle_event_priority etc are added to define event type priority.The content of definition It may include deployment scenario, life cycle events title or ID, priority and the priority scope of application etc., the embodiment of the present invention pair This is not especially limited.

It should be noted that, in addition to VNFC priority and event type priority, can also be certain lifes in actual deployment Order periodic event assigned priority.For example, being the difference on same physical equipment to balance the processing load of physical equipment VNFC sets priority；For another example, to cope with special circumstances, setting priority is forced.If being set in advance for certain life cycle events Priority is determined, then when triggering the processing of life cycle events, should also take into account.

In practical applications, when some VNF encounters multiple life cycle events simultaneously, (i.e. multiple life cycle events are simultaneously When hair), since certain life cycle events execute sequence in the presence of inevitable, it is therefore desirable to consider concurrent multiple life cycle things The problem of how part is handled, is otherwise likely to occur ambiguity, causes to handle mistake.For this purpose, Life Cycle provided in an embodiment of the present invention The processing method of phase event, when collision event group being not present in concurrent multiple life cycle events, by predetermined VNFC priority and event type priority successively trigger the processing of concurrent multiple life cycle events, to avoid giving birth to more The processing mistake that life periodic event may cause.

Further, as shown in figure 3, the processing method of life cycle events provided in an embodiment of the present invention, described After VNFM obtains the concurrent N number of life cycle events (S201) of the same VNF, can also include:

If there is at least one set of collision event group in S203, N number of life cycle events, the VNFM discarding is described extremely Life cycle events in few one group of collision event group, so that remaining life cycle thing in N number of life cycle events Part is directed to different VNFC.

S204, the VNFM are successively triggered described surplus according to VNFC priority predetermined and event type priority The processing of remaining life cycle events.

That is, when two or more life cycle events (the conflict thing that there is conflict in concurrent multiple life cycle events Part group) when, the processing method of life cycle events provided in an embodiment of the present invention, by abandoning the life in every group of collision event group Periodic event is ordered so that remaining life cycle events are directed to different VNFC, to guarantee remaining life cycle events not Conflict, and under the premise of guaranteeing that remaining life cycle does not conflict, according to VNFC priority predetermined and event type Priority successively triggers the processing of the remaining life cycle events, avoids the occurrence of processing mistake.

Further, as shown in figure 4, the processing method of life cycle events provided in an embodiment of the present invention, described After VNFM obtains the concurrent N number of life cycle events (i.e. S201) of the same virtual network function VNF, can also include:
