A method and device for deploying a virtual network element

Abstract

The invention provides a deploying method and device for a virtual network element. The deploying method comprises: receiving a virtual network element template VNFD parameter of a virtual network element, and generating a VNFD of the virtual network element, wherein the VNFD parameter comprises configuration parameters and deployment strategies of the virtual network element, and the deployment strategies comprise an affinity deployment strategy and an incompatibility deployment strategy; analyzing the VNFD of the virtual network element to obtain the configuration parameters and the deployment strategies of the virtual network element; determining a deployment position of the virtual network element according to a global resource view as well as the configuration parameters and the deployment strategies of the virtual network element, and sending a virtual resource application request according to the deployment position; and allocating resources according to the virtual resource application request, thus accomplishing instantiation of the virtual network element. By adopting the method, the automatic deployment process of the virtual network element is simplified, meanwhile, the deployment problem of affinity and incompatibility between virtual network elements is solved, and the reliability of the network elements and a system is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for deploying a virtual network element. Background technique [0002] At present, the automatic deployment of virtual network elements only solves the implementation of the deployment strategy of affinity and anti-affinity between virtual deployment units VDUs in virtual network elements, and does not involve the affinity and anti-affinity between virtual network elements. The execution of the specific deployment strategy, and the analysis of the virtual network element template VNFD can only be carried out in the virtual network element management center VNFM, so the resource allocation process requires more interactions between the VNFM and the network function virtualization dispatching center NFVO, which is relatively complicated. Contents of the invention [0003] The purpose of the present invention is to provide a virtual network element de...
