城域网作为移动回传网络、专线、人工智能(artificial intelligence,AI)智算中心、泛在算力连接等重要业务的基础设施,是全球传输技术领域的研究热点与产业竞争焦点。随着新业务从信息消费向产业应用拓展,在网络切片有望成为信息通信服务提供的新模式背景下,全面阐述了多维融合转发的核心理念、“以太网内生时分复用(time division multiplexing,TDM)”的核心转发机制、切片分组网(slicing packet network,SPN)的系统架构和技术体系。当前,SPN已实现规模应用部署,并形成系列国际标准,成为ITU-T继同步数字体系(synchronous digital hierarchy,SDH)、光传送网(optical transport network,OTN)之后的新一代传输网技术体系。
The metro network serves as critical infrastructure for mobile backhaul networks
dedicated lines
artificial intelligence (AI) computing centers
and ubiquitous computing power connectivity
making it a global research focus and competitive frontier in transport technologies. As emerging applications evolve from information consumption to industrial applications
network slicing is anticipated to emerge as a novel paradigm for information communication service delivery. The core concept of multi-dimensional converged forwarding
the core forwarding mechanism of “Ethernet-native time division multiplexing (TDM)”
as well as the system architecture and technical framework of the slicing packet network (SPN) were comprehensively elaborated. At present
SPN has achieved large-scale commercial deployment and established a series of international standards
becoming the next-generation transport network technology system of International Telecommunications Union Telecommunication Standardization Sector (ITU-T) following synchronous digital hierarchy (SDH) and optical transport network (OTN).
