摘要
NFV(network function virtualization,网络功能虚拟化)系统主要包括NFVI、VNF和MANO三大功能模块以及子功能模块,相对传统网络架构,网络功能虚拟化解耦了传统专用设备的软硬件,引入了虚拟化技术来池化物理资源,对网络架构的改动很大。对NFV弹性技术进行了分析,强调了网络虚拟化的弹性目标主要是确保业务的连续性,应用设计本身和虚拟化设施均受此目标影响。归纳了弹性结构设计原则,给出弹性用例并进行总结。
According to NFV ETSI standard architecture, NFV system mainly includes NFVI, VNF and MANO three function modules and sub function modules. NFV elastic technology was analyzed, and it was emphasized that the flexible goal of network virtualization was mainly to ensure the continuity of the business, application design and virtualization facilities were also affected by this goal.And the principle of elastic structure design was summarized.
