Abstract

The invention discloses a method for establishing a VNF, NFVO and a network system, and relates to the field of communication technology. The method includes: NFVO requests VIM to allocate virtual resources, and when it is judged that an abnormal situation occurs, NFVO sends an instruction to create a VNF instance to VNFM, Assign permission to create VNF instances; VNFM requests VIM to allocate virtual resources for creating VNF instances and create VNF instances. In the establishment method, NFVO and network system of the present invention, a VNF instance is established in the indirect mode, and the direct mode is used as the backup mode in case of failure. When the indirect mode is executed to establish the resource call of the VM to fail, it will automatically sense and switch to the direct mode to complete The resource call created by the VM, and the subsequent automatic establishment and monitoring operations increase the fault recovery capability of the indirect mode, and the changes to the NFV architecture are small, which is beneficial to the actual operation of the live network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a VNF establishment method, NFVO and network system. Background technique [0002] NFV (Network Functions Virtualization, Network Functions Virtualization) refers to the use of virtualization technology to implement various network device functions on standardized general-purpose IT devices (x86 servers, storage and switching devices). After adopting NFV, on the one hand, the functions of network equipment no longer depend on dedicated hardware, and the cost of IT equipment based on the x86 standard is low, which is expected to save equipment investment costs for operators; on the other hand, through software and hardware decoupling and functional abstraction, Resources can be fully and flexibly shared to achieve rapid development and deployment of new services, and perform automatic deployment, elastic scaling, fault isolation, and self-healing based on actual bus...
