摘要
为了实现“弹性、伸缩、快速业务迁移”的网络特性,基于以下原则重新设计NFV系统:前端无状态、横向可扩展、单点失效不影响业务,分离业务处理单元和存储节点。跨DC的虚拟化核心网容灾体系可以利用现有技术,在不同的通信云之间近乎无损地迁移虚拟化网元。
To achieve the goal of "flexible,scalable and fast business migration",the NFV system is redesigned based on the following principles:front-end statelessness,horizontal scalability,single point of failure does not affect the business.Business pro?cessing units and storage nodes are seperated.Disaster recovery system of cross-DC virtual core network can use existing technology to migrate virtualization network elements almost non-destructively between different communication clouds.
