基于开源技术的WoMANO技术架构研究

摘要

国内外有影响力的标准组织近年来纷纷成立专门的工作组来开展NFV的相关标准研究。文章对NFV标准组织近几年的研究成果以及NFV标准组织的最新进展进行了介绍。NFV架构主要包括NFVI、VNF和MANO三大功能模块以及子功能模块，NFV在增加通信网络灵活性的同时对网络管理和编排提出新的功能需求。基于欧洲电信标准组织网络功能虚拟化架构、功能、最新标准现状和业界进展，针对NFV管理和编排具体需求，文章分析NFV中的网络服务编排管理模块、虚拟化网络功能管理模块、虚拟资源管理模块、视图管理模块及其开源支撑技术，结合中国联通网络业务特点，给出一种WoMANO技术架构，为运营商开展NFV实践提供技术参考。%In recent years, many inlfuential international and domestic standard organizations have established special working groups to research NFV related standards as an emerging technology. In the scenario of standard progress, the recent two years’ achievements and the latest research progress of NFV standard organization are introduced. NFV architecture includes NFVI, VNF and MANO three function modules and sub function modules, NFV not only increases the lfexibility to communication network but also puts forward new demands on network management and orchestration. Referring to the NFV architecture of ESTI and latest standards and industry progress, according to the speciifc needs of NFV management and orchestration, various modules of NFV and related open source technologies are analyzed, including NFVO, VNF management, NFVI management and Web UI management. Combined with business characters of China Unicom, a WoMANO architecture is proposed, which wil give technical references to the carrier.
