分组增强型OTN设备在城域传送网中的应用探讨*

摘要

Packet-OTN technology is the future di-rection of transport network technology development. The paper will propose the various application sce-narios of Packet enhanced Optical Transport Net-work (OTN) equipment in the metro transport net-work. Firstly, the development situation of Packet enhanced OTN equipment is described in this pa-per. Second, the new demands of metro transport network are analyzed. Finally, the various applica-tion scenarios in the metro transport network are discussed and proposed.%　　分组技术在光传送网（OTN）设备中的引入是未来传送网技术发展的方向。文章针对分组增强型OTN设备的功能特点和城域传送网的需求特点，提出了多种该类设备在城域传送网中的应用场景。首先介绍了分组增强型OTN设备和开发现状，之后分析了目前城域传送网面临的新需求，最后讨论并提出了该类设备在城域传送网中的多种应用场景。
