摘要

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。

Abstract

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).
