摘要
通过分析IP城域网现状及其在资源利用、业务部署和管理维护等方面存在的问题和不足,结合SDN集中管控思想和NFV设备虚拟化思路,提出了基于vBRAS的新型IP城域网架构,并着重从网络架构、设备定位、实现模式、互通接口、业务流程和部署方案等方面给出了详细建设思路,最后总结并展望了未来IP城域网演进的方向。
By analyzing the current situation of IP MAN and its problems in resource utilization,service deployment and management and maintenance,combined with the idea of SDN centralized management and NFV device virtualization,the new IP MAN architecture based on vBRAS is proposed,and the detailed construction of network architecture,device positioning,implementation mode,interworking interface,business process and deployment scheme is given. Finally the direction of IP MAN evolution in the future is summarized and prospected.
