随着SDH和MSTP网络面临退网,OTN将取代SDH/MSTP网络,下沉到网络的边缘节点。同时,客户业务的需求也正在发生快速变化,而分组增强型OTN在其承载业务上存在着各种问题和挑战。提出了基于OSU的城域网优化OTN(M-OTN)技术体系,并结合其技术本质和实验测试数据,全面分析了M-OTN/OSU的技术优势。结果表明,M-OTN/OSU 相较于分组增强型 OTN 技术在多个方面具有明显优势。M-OTN/OSU在现网中如何应用部署以及网络演进,同样备受关注。结合 M-OTN/OSU 的技术特点和现网中已部署设备情况,分享了对于M-OTN/OSU的组网方案,以及网络演进策略的研究。
With SDH and MSTP networks facing withdrawal from the network
OTN will replace SDH/MSTP networks and sink to the edge of the network.At the same time
the requirements of customers’ services are also changing rapidly
but the packet enhanced OTN has various problems and challenges in carrying these services.Therefore
the M-OTN technology system based on OSU was proposed
and the technical advantages of M-OTN/OSU were comprehensively analyzed by combining its technical essence and experimental data.The results show that M-OTN/OSU has obvious advantages over packet enhanced OTN technology in many aspects.The application and deployment of M-OTN/OSU in the field network and network evolution are of great concern.Combined with the technical characteristics of M-OTN/OSU and the deployed devices in the field network
the research of M-OTN/OSU in networking scheme and network evolution strategy was shared.
