A virtual resource management method, virtual resource management device and server

Abstract

This application provides a virtual resource management method, a virtual resource management device and a server, which are used for the virtual resource management device to obtain backup network element configuration information based on the current virtual resource information of the virtual service network element, and redeploy according to the backup network element configuration information When virtual service network elements are used, the consistency of virtual resources before and after virtual service network elements are re-deployed is guaranteed. The method in the embodiment of the present application includes: obtaining the current virtual resource information of the virtual service network element, the current virtual resource information is used to represent the current virtual resource of the virtual service network element, and there is at least one virtual service network element; generating a virtual service according to the current virtual resource information The backup network element configuration information of the network element, the backup network element configuration information is used to deploy the virtual service network element; when the virtual service network element needs to be redeployed, the target virtual service network element is deployed according to the backup network element configuration information, and the target virtual service network element The virtual resource of the element is the same as the current virtual resource of the virtual service network element.

Description

technical field [0001] The present application relates to the communication field, in particular to a virtual resource management method, a virtual resource management device and a server. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) technology can migrate the functions of each network element used in the communication network from the current dedicated hardware platform to a general-purpose Commercial Off-The-Shelf (COTS) server . In the NFV scenario, the virtual network function (VirtualNetwork Function, VNF) is deployed and installed through the virtual network function manager (Virtualisd Network FunctionManager, VNFM) using the initially released virtual network function module descriptor (Virtualized NetworkFunction Descriptor, VNFD) file , including virtual resource information of a plurality of VNFs, and the virtual resource information may specifically be the specification, quantity and network connection of a...

[0004] However, since the VNFM does not have the ability to dynamically refresh the VNFD file, before the DC fails, when the virtual resource changes caused by the VNF's elastic scaling, capacity expansion operation, or upgrade operation, the VNFM cannot update the virtual resource information of the changed VNF. VNFD file, then after the DC failure recovery, you can only use the initially released VNFD file to redeploy and install the VNF and the virtual resources of the VNF, which leads to the inconsistency between the virtual resources of the VNF after the DC failure recovery and the VNF virtual resources before the DC failure
