Refer to Fig. 1, including following flow process:
S101, in the former VNFM that former NFVO is managed, needing of determining that this former VNFM managed migrates
VNF。
This step is concrete, and each VNFM under each NFVO management can be as former VNFM, can be by former VNFM
According to default VNF migration strategy, calculate and move out the need of part VNF managed, the need to
Move out, then report NFVO.
VNF migration strategy can be according to the load of VNFM, the service request success rate of VNF and/or the industry of VNF
Business request deadline these three performance parameter is formulated.
The load of VNFM refers to that VNF number currently managed for VNFM accounts between VNFM maximum management number
Percentage ratio, this percentage ratio is the highest, illustrates that the load of VNFM is the highest, if the load of VNFM is too high, will have
The management quality of VNFM may be reduced so that the service request of VNF can not get replying timely and effectively.
The service request success rate of VNF refers to when within a period of time, VNF initiates the service request such as elastic telescopic,
The percentage ratio that request is successfully completed, this percentage ratio is the highest, illustrates that the service request success rate of VNF is the highest,
The service request success rate of VNF is the important indicator of VNFM management quality, if the service request success of VNF
Rate is the highest, then even if VNFM is under full load situation, is also not necessarily intended to migrate VNF.
The service request deadline of VNF refers to be successfully completed from VNF initiating business request to request spent
Time, the time is the shortest more good, if most service request deadline is both greater than expeced time, then just
This VNF that moves out can be considered, reduce the load of VNFM, improve the response efficiency of VNFM.

Receiving the amendment operation of user, VNFM user specified is as purpose VNFM；Or receive user really
Recognize operation, using the VNFM that confirms through user as purpose VNFM.Step is entered after user revises confirmation
S103。
S103, the VNF that these needs migrate is migrated to this purpose VNFM.
Complete migration step according to above-mentioned purpose VNFM finally determined, same NFVO may be migrated to
Other existing VNFM in, or in the newly-built VNFM under same NFVO, or the existing VNFM under other NFVO
In, or in the newly-built VNFM under other NFVO.
