摘　　要：针对现有城域网存在的诸多问题,以业务控制层作为突破口,综合利用SDN、NFV、云计算等技术,在三层充分解耦的基本原则下,提出了一体化、X86转控分离、专用硬件转控分离等多种虚拟化方案,并结合运营商CO向DC化改造项目,针对不同业务场景给出了相应改造方案及部署模式的建议,助力城域网向敏捷、高弹性、智慧的方向演进。In view of the existing problems in the metropolitan area network, the service control layer was grasped by using the SDN, NFV and cloud computing technology. Based on the three-layer decoupling principle, multiple virtualization schemes including the integration, X86 separation and dedicated hardware control separation were proposed. Combined with different scenarios, the suggestions on the corresponding reform solution and deployment mode were presented to drive the metropolitan area network to the fast, flexible and intelligent direction.
