Method and device for service deployment in virtualized network

Abstract

The invention provides a method and device for deploying services in a virtual network. In this method, the virtual network function manager receives an instantiation request, and the instantiation request includes a VNF instance identifier and a first deployment preference identifier; according to the VNF instance identifier, a VNF deployment template VNFD is obtained, and the VNFD includes at least two potential deployment nodes. Descriptive information and at least two deployment preference description information; wherein, the description information of each potential deployment node includes the node information and deployment conditions of the potential deployment node, and each deployment preference description information includes the node that needs to be deployed corresponding to the deployment preference Deployment information; according to the first deployment preference identifier and the VNFD, determine the node information and deployment information of the nodes to be deployed; send the determined node information and deployment information of the nodes to be deployed to the virtual infrastructure manager. Therefore, the business requirement that one business template cannot support multiple deployment preferences in the prior art is solved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for service deployment in a virtualized network. Background technique [0002] Network Function Virtualization (NFV) refers to the use of general-purpose hardware devices and virtualization technology to carry the functions of special-purpose devices in traditional networks, thereby reducing the expensive cost of deploying special-purpose devices. The software is not bound to proprietary hardware, so that network device functions no longer depend on specialized hardware. At the same time, using the characteristics of cloud computing, resources can be fully and flexibly shared to realize the rapid development and deployment of new services, and to perform automatic deployment, elastic scaling, fault isolation and self-healing based on actual business needs. In the NFV architecture, the party that receives the instantiation request and instantiates the cor...
