一种基于NFV架构的服务质量保障方法

A Service Quality Assurance Method Based on NFV Architecture

基于MANO架构,能够完成网元的生命周期管理,但是缺乏对资源池做容量预测分析,难以保障网元的服务质量需求。文章提出了一种基于NFV的服务质量保障方法,即在现有MANO系统中加入服务质量管理功能。通过监控模块收集网元的链路拓扑信息,构建虚拟资源与物理资源的映射关联,一旦网元内部出现故障,能够做出自愈操作。

Based on the MANO architecture,it can complete the life cycle management of network elements,but it lacks capacity prediction and analysis of resource pools,and it is difficult to guarantee the service quality requirements of network elements.This paper proposes a NFV-based service quality assurance method,that is,adding service quality management functions to the existing MANO system.Through the monitoring module,the link topology information of the network element is collected,and the mapping association between virtual resources and physical resources is constructed.Once a fault occurs inside the network element,a self-healing operation can be performed.
