Embodiment Construction

[0070] figure 1 NFV architecture diagram for network function virtualization. This architecture diagram is the reference architecture defined in the NFV ISG.

[0071] Such as figure 1 As shown, NFV-MANO (NFV Management and Orchestration) consists of network function virtualization orchestrator (NFVO Orchestrator), virtualized network function manager (VirtualNetwork Function Manager, VNFM) and virtualized infrastructure manager (VirtualizedInfrastructure Manager, VIM) Composed together.

[0072] NFVO is mainly used to realize the network service (Network Service, NS) life cycle management (such as deployment / expansion / reduction / offline, etc.) in the operator domain (one or more data centers), and the network function virtualization infrastructure layer (Virtualised Network Function Infrastructure, NFVI) resource orchestration, policy management and other functions; Orchestrator decomposes the requirements for each VNF (Virtualized Network Function) according to the Network ...

Abstract

The invention relates to a deployment method and deployment system of a virtualized network. The virtualized network is formed by a plurality of parts. The method comprises: a first network function virtualization orchestrator (NFVO) receives a first-part deployment request sent by a service operation and management platform, wherein the first-part deployment request includes resource reservation indication; a second NFVO receives a second-part deployment request; the second NFVO obtains orchestrating information of a first part and carries out orchestrating on a second part based on the orchestrating information of the first part; and when the orchestrating information of the first part meets the deployment request of the second part, the first NFVO and the second NFVO request resource allocation. Resource reservation is carried out on the part needing deployment and no resource allocation is performed after resource reservation; and after orchestrating planning of all deployment parts is completed, resource allocation is carried out. Therefore, when a virtual network service is formed by a plurality of parts and virtualized network deployment is performed, mutual coordinate of all parts is realized, so that flexibility and universality of network deployment are improved.

Description

technical field [0001] The present invention relates to the field of virtual network technology, in particular to a method and system for deploying a virtualized network. Background technique [0002] Network Function Virtualization (NFV) is a standard development project under the European Telecommunications Standards Institute (ETSI), which mainly develops industry-wide standards for network cloudification. Based on modern IT virtualization technology, it provides a new network product environment, reduces costs, improves efficiency, and increases agility. By using general-purpose hardware such as x86 and virtualization technology, software processing of many functions is carried. Thereby reducing the expensive equipment cost of the network. Through software and hardware decoupling and functional abstraction, network device functions no longer depend on dedicated hardware, resources can be fully and flexibly shared, and rapid development and deployment of new services ca...
