电信运营商NFV未来网络管理体系演进关键问题

网络功能虚拟化(NFV)是电信级业务云化的核心技术和架构,是未来网络演进的必然趋势.NFV给通信网络带来了新的能力,同时也要求对现有的设备运行、管理、维护和配置模型增加新的管理和编排(MANO)功能.首先对物理网元的网管体系架构及未来演进规划进行总结研究,然后对NFV的引入对现网设备管理方式的变化及新网管架构功能进行总结,深入研究NFV MANO与运营支撑系统(OSS)协同关系、MANO与其他周边网元组网方案等关键问题,最后从电信运营商角度,基于NFV MANO解耦程度,提出MANO部署及演进策略.

Key problems of telecom operators' NFV future network management system evolution

Network function virtualization (NFV) is the core technology and architecture of telecom-level business to cloud,which is the inevitable trend of future network evolution.NFV brings new capabilities to the communications network,at the same time,it requires new management and orchestration (MANO) capabilities for existing equipment operations,management,maintenance and configuration models.First of all,the network management system architecture and future evolution planning of the physical network element were summarized,and by the coming of NFV technology,the changes of the existing network equipment management method and the new network management architecture and function were concluded.The coordination of NFV MANO and operation support system (OSS),NFV MANO and other peripheral network was deeply researched.Finally,from the perspective of telecom operators,the deployment and evolution strategy ofNFV MANO based on decoupling level was suggested.
