摘要
针对传统宽带IP城域网面临的挑战和问题,基于软件定义和虚拟化等技术,文章提出宽带IP城域网络需要从简单的连接型网络向智能的功能型网络演进的思路和架构,并给出新形势下的应用场景,从而满足其智能化运营的发展需求。
Aiming at the challenges and problems that the traditional broad band IP Metropolitan Area Network are facing and based on Software Defined Network and Network Function Virtualization technologies, this paper proposes the train of thought and architecture that the Metropolitan Area Network needs to evaluate from connective network to smart functional network. Combining with the new situation, it describes the application scenarios to satisfy the needs of the development of intelligent operation.
