摘　　要：数字经济发展需要运力和算力共同提升。算力的释放需要以大带宽、广连接、低时延为特征的高性能传输网络。国家对信息通信行业绿色低碳发展提出要求,开展极简传输网络演进势在必行。为此,分析传输网络的现状及问题,提出极简传输网络演进的思路和方案,通过省内干线和城域网的同步数字体系(Synchronous Digital Hierarchy,SDH)网络与VC-OTN(Virtual Container-Optical Transport Network)融合演进、分组传送网(Packet Transport Network,PTN)网络与切片分组网(Slicing Packet Network,SPN)网络的融合演进,打造一张高品质、高性能、低碳的极简传输网络。The development of the digital economy requires the combined enhancement of transportation capacity and computing power.The release of computing power requires a high-performance transport network characterized by large bandwidth,wide connectivity,and low latency.The government also puts forward requirements for the green and low-carbon development of the information and communication industry,and it is imperative to carry out the evolution of the simplified transport network.This article analyzes the current situation and problems of the transport network,proposes ideas and solutions for the evolution of the simplified transport network,and creates a high-quality,high-performance,low-carbon minimalist transmission network through the integration and evolution of Synchronous Digital Hierarchy(SDH)networks and Virtual Container-Optical Transport Network(VC-OTN)as well as the integration and evolution of Packet Transport Network(PTN)networks and Slicing Packet Network(SPN).
