多频段实现的5G无域网络运营：迈向光连续体架构
Beyond 5G Domainless Network Operation enabled by Multiband: Toward Optical Continuum Architectures
摘要：
公共和私人创新项目都致力于设计、原型制作和演示一种基于多波段（MB）光传输和交换网络的新型端到端集成分组光传输架构。从本质上讲，MB有望成为下一个技术演进，以最具成本效益的方式应对5G移动网络的流量需求和服务要求。得益于MB传输，划分为多个层级和域的传统电信架构可以向光网络连续体发展，其中边缘接入节点与顶层节点全光互连，连接内容分发网络（CDN）和互联网交换点（IXP）。本文概述了实现电信网络从数据、控制和管理层面的架构转变所面临的技术挑战和创新要求。
英文摘要：
Both public and private innovation projects are targeting the design, prototyping and demonstration of a novel end-to-end integrated packet-optical transport architecture based on Multi-Band (MB) optical transmission and switching networks. Essentially, MB is expected to be the next technological evolution to deal with the traffic demand and service requirements of 5G mobile networks, and beyond, in the most cost-effective manner. Thanks to MB transmission, classical telco architectures segmented into hierarchical levels and domains can move forward toward an optical network continuum, where edge access nodes are all-optically interconnected with top-hierarchical nodes, interfacing Content Delivery Networks (CDN) and Internet Exchange Points (IXP). This article overviews the technological challenges and innovation requirements to enable such an architectural shift of telco networks both from a data and control and management planes.
