摘要
SDH/MSTP网络目前已经逐渐停止运营,而ONT逐渐取代SDH/MSTP网络,并且朝着城域网延伸拓展,这对ONT网络技术提出了更严格要求。城域传送网的发展面临挑战,在这种局势下,人们提出了以OSU为核心的M-OTN技术在城域网中的运用。文章对其进行详细介绍和分析,阐述具体情况与标准,并且针对OSU技术进行重点阐述和分析,阐述OUS帧结构与开销、无损带宽吊证机制等,充分考虑设备形态与现网演进发展趋势。通过对主流厂商的M-OTN样机进行测试、测样,结果证明OSU在时延、带宽调整、承载各方面都有显著优势。
SDH/MSTP network has gradually ceased operation at present,and ONT gradually replaces SDH/MSTP network,and expands toward the metropolitan area network,this puts forward stricter requirements on ONT network technology.The development of metropolitan area transmission network is facing challenges.In this situation,people have proposed the application of M-OTN technology with OSU as the core in metropolitan area networks.The article introduces and analyzes it in detail,expounds the specific conditions and standards,and focuses on the OSU technology and analyzes it,expounds the OUS frame structure and overhead,lossless bandwidth certification mechanism,etc.,and fully considers the equipment form and the development trend of the current network evolution.Through testing and sampling of M-OTN prototypes of mainstream manufacturers,the results prove that OSU has significant advantages in delay,bandwidth adjustment,and bearer.
