NFV-based virtual resource configuration method and system

Abstract

The present invention provides a virtual resource configuration method and system based on NFV, wherein the method includes: VNFM sends a resource authorization request message corresponding to the virtual resource application requirements to NFVO, receives the resource authorization result message returned by NFVO, and resources authorization The result message carries resource authorization information; VNFM sends a virtual resource configuration request message to VIM, and the virtual resource configuration request message carries resource authorization information, and VIM verifies the resource authorization information, and performs resource configuration operations according to the verification result. The method and system of the present invention can realize precise management of virtual resource configuration authorization operations. VNFM needs to obtain resource authorization information for accessing VIM to ensure that each resource configuration needs to be authorized, and VIM needs to verify the resource capacity of each configuration operation. Ensure safe and controllable configuration of virtual resources, improve system stability and user experience.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to an NFV-based virtual resource configuration method and system. Background technique [0002] NFV (Network Function Virtualization, Network Function Virtualization) has become a key technology for telecom operators' network architecture reconstruction, and has been gradually applied to live network deployment. MANO (NFV Management and Orchestration, NFV management and scheduling) is responsible for the deployment of virtual network elements VNF (Virtualized Network Function, virtual network function) and the unified configuration of virtual resources. MANO includes three functional units: NFVO (NFV Orchestrator, network function virtualization scheduler), VNFM (VNF Manager, virtualized network function manager) and VIM (Virtualized Infrastructure Manager, virtual infrastructure manager). When VNFM is responsible for the virtualization of VNF When configuring resou...

AI Technical Summary

Problems solved by technology

The existing virtual resource authorization scheme has defects: VNFM only needs to request authorization once to obtain tenant information, and subsequent resource configuration can be operated without authorization; the resource capacity requested by VNFM is inconsistent with the actual configured resource capacity, resulting in out-of-control resource management

Therefore, there are security risks and loopholes in the current virtual resource configuration operation authorization method adopted by the industry. It can neither guarantee the effectiveness of resource configuration authorization nor achieve precise control of resource configuration capacity. Therefore, there are security risks and loopholes.
