Virtual resource configuration method and system based on NFV

Abstract

The invention provides a virtual resource configuration method and system based on an NFV. The method comprises the steps that a VNFM sends a resource authorization request message corresponding to avirtual resource application requirement to an NFVO and receives a resource authorization result message returned by the NFVO, and the resource authorization result message carries resource authorization information; and the VNFM sends a virtual resource configuration request message to the VIM, the virtual resource configuration request message carries resource authorization information, and theVIM verifies the resource authorization information and performs resource configuration operation according to a verification result. According to the method and system, accurate management of virtualresource configuration authorization operation can be realized; the VNFM needs to obtain the resource authorization information for accessing the VIM, it is guaranteed that each time of resource configuration needs to be authorized, the VIM needs to verify the resource capacity of each time of configuration operation, it is guaranteed that virtual resource configuration is safe and controllable,and the stability of the system and the user experience are improved.

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.
