摘要
分析了运营商传统IP城域网自身架构、网络运维和业务运营等面临的挑战和问题,分析了当前业内v BNG技术方案,提出了基于SDN/NFV的新型IP城域网架构,并分析了该架构具有的五大特征,然后分别从转发层面、控制层面、网络业务编排和能力开放及业务层面给出了向新型IP城域网架构的演进策略。
It firstly analyzes the challenges and problems in traditional broadband IP MAN on architecture, network operation and mainte- nance, business operations, etc. Then it analyzes the model of vBNG, proposes a new MAN network architecture based on SDN/NFV, analyzes the five features of the architecture. And then gives the evolvement strategy to the new IP MAN architec- ture from the forwarding level, the control level, the network service orchestration and the service level respectively.
