Embodiment 1
[0125] The present invention provides a backup method for a virtualized network, the method comprising:
[0126] Step 1: the network function virtualization scheduler NFVO receives a backup request, and the backup request includes a VNF backup request or a VNFM backup request or an NFVO backup request;
[0127] Step 2: When the backup request is the VNF backup request, the NFVO performs a VNF backup operation according to the VNF backup request;
[0128] When the backup request is the VNFM backup request, the NFVO performs a VNFM backup operation according to the VNFM backup request, and performs a backup operation of each VNF managed by the VNFM after the VNFM backup is successful;
[0129] When the backup request is the NFVO backup request, the NFVO performs the NFVO backup operation according to the NFVO backup request, and after the NFVO backup is successful, performs the backup operation of each VNFM managed by the NFVO; and performs after each VNFM backup is successful ...
Embodiment 2
[0197] The backup method and recovery method of the virtualized network in the present invention will be further explained below in conjunction with the accompanying drawings.
[0198] Such as figure 1 As shown, the process of VNF backup in this embodiment is as follows:
[0199] Step 101: USER sends VNF backup request to NFVO.
[0200] Step 102: After receiving the request, the NFVO first checks the command information to check whether it meets the backup requirements, if it meets the requirements, proceed to the next step, and if not, return.
[0201] Step 103: NFVO sends VNF backup request to VNFM.
[0202] Step 104: The VNFM collects and backs up backup data such as the managed VNF system configuration information and topology association information.
[0203] Step 105: the VNFM sends a VNF data backup request to the VNF.
[0204] Step 106: The VNF receives the backup request from the VNFM, and starts backing up service data.
[0205] Step 107: After the VNF backup is...

Abstract
The invention provides a virtual networkbackup and recovery method. The method comprises the steps that: a network function virtualization scheduler NFVO receives a backup request, wherein the backup request comprises a VNF backup request or a VNFM backup request or an NFVO backup request; when the backup request is the VNF backup request, the NFVO carries out a VNF backup operation according to the VNF backup request; when the backup request is the VNFM backup request, the NFVO carries out a VNFM backup operation according to the VNFM backup request and carries out a backup operation on each VNF managed by the VNFM after VNFM backup success; when the backup request is the NFVO backup request, the NFVO carries out an NFVO backup operation according to the NFVO backup request and carries out the backup operation on each VNFM managed by the NFVO after the NFVO backup success; and the backup operation of each VNF managed by each VNFM is carried out after each VNFM backup success. The virtual network backup and recovery method provided by the scheme can be used for effectively realizing quick backup and recovery on physical resources per se.
Description
technical field [0001] The invention relates to the field of backup and recovery, in particular to a backup and recovery method and a corresponding device under a virtualized network. Background technique [0002] With the maturity of IT technology, more and more telecom operators adopt virtualization technology to reduce their CAPEX (Capital Expenditure, capital expenditure) and OPEX (Operating Expense, operating cost), based on NFV (Network Function Virtualization, network function virtualization) protocol Standard virtualization technology solutions can largely meet the technical implementation needs of telecom operators. Therefore, adopting the NFV standard architecture to realize the solution of core network virtualization deployment has become an inevitable choice for more and more operators. [0003] The core idea of the so-called NFV is to realize the decoupling and separation of hardware and software of telecommunication equipment. In the NFV standard, each netw...
