城域网重构思路

Metropolitan area network re-architecture

数字化、智能化已成为基础设施建设的主要目标,城域网重构作为网络演进的核心环节,直接决定运营商网络的先进性水平。面向新需求,详细剖析关键技术发展及应用方式,结合城域网重构目标架构,提出城域网重构分阶段演进建议,为后续技术研究和网络重构演进提供指引。

Digitization and intelligentization have become the main goals of infrastructure construction. As the most important part of the evolution of the network, the re-architecture of metropolitan area network（MAN） has directly determined the advanced level of the operator＇s network. According to the new requirements, detail evolution of MAN re-architecture was discussed in detail based on the development of the key technologies and its application scene. Finally, the phased evolution solution was proposed, which can provide guidance for the technology research and the evolution of network re-architecture.
