VNF (Virtualised Network Function) package and deleting method and device for mirror image file referred thereby

Abstract

The invention provides a VNF (Virtualised Network Function) package and a deleting method and device for a mirror image file referred thereby, and aims at solving the problem that the relation among the VNF package, the mirror image file, and a mirror image instance generated by the mirror image file is complex and the mirror image file and the like are easily mistakenly deleted and leaked while deleting the VNF package in the prior art. The method comprises the following steps: S101, searching a mirror image file record B including the name of the VNF package according to the VNF package name corresponding to a first identifier VNFP_id; S102, if the mirror image file record B is not empty, deleting the VNF package name from the content of the mirror image file record B in a database; and S103, searching the database to obtain the mirror image file M without being interfered by any VNF package, and searching the database to determine whether the mirror image file M is instantiated; if so, searching an instantiated mirror image N according to a second identifier Image_file-id of the mirror image file M; and deleting the instantiated mirror image N. With the adoption of the method and the device, the defect of avoiding mistaken deleting and leaking can be achieved.

Description

technical field [0001] The present invention relates to communication technology / computer technology, in particular to a VNF package and a method and device for deleting a mirror image file referenced by the VNF package. Background technique [0002] With the development of communication technology and cloud computing technology, NFV technology has begun to appear and continue to develop and improve. As its management and scheduling system, NFVO directly faces various business needs of users, and realizes the scheduling and coordination of various virtual resources and virtualized network elements VNF through human-computer interaction. [0003] NFV (Network Function Virtualization, Network Function Virtualization) was initiated by 13 major telecom operators in the world. It is an organization participated by many equipment manufacturers and IT (Information Technology, Information Technology) manufacturers. It aims to define the concept of operator network function virtualiz...

AI Technical Summary

Problems solved by technology

The usual deletion of a VNF package also needs to delete the referenced image file, but in the prior art, the two are usually handled separately, and with the increase and expansion of NFV network functions, a VNF package usually references multiple Mirror files, this will bring a lot of trouble to the operator, and the processing process contains very complicated judgment logic, which can easily cause accidental or missing deletion of mirror files

[0006] That is to say, in the prior art, the relationship between the VNF package and the image file and the image instance generated by the image file is complicated, and it is easy to cause accidental or missing deletion of the image file when deleting the VNF package.
