摘要:

随选网络主要基于SDN、NFV和云技术,实现网络的软化、自动化、智能化以及为用户提供按需配置网络的能力,重点论述了随选网络的架构和关键技术,通过引入协同编排器来编排SDN、NFV网络和云资源,通过引入 SD-WAN 的 overlay 技术快速建立网络通路,并提出了面向中小企业的随选网络的四大应用场景。随选网络可以为客户提供“可视”“随选”“自服务”的全新网络体验。

关键词: 随选网络, SDN, NFV, 云计算, 编排器

Abstract:

The network on demand is mainly based on SDN,NFV and cloud technologies,which realizes the softening,automation and intelligence of the network and provides users with the ability to configure the network on demand.The architecture and key technologies of the network on demand were emphasized,and the collaborative orchestration was introduced.The SDN,NFV network and cloud resources were arranged,and the network path was quickly established by introducing the SD-WAN overlay technology,and four application scenarios of the network on demand for small and medium enterprises were proposed.Network on demand can provide customers with a new web experience of “visual” “on-demand” and “self-service”.

Key words: network on demand, software defined networking, network function virtualization, cloud computing, orchestrator
