摘要
分组增强型OTN(POTN)集成了分组传送网(PTN)和光传送网(OTN)的技术优势,并力争实现传送功能的有机融合和优化裁剪,更好地适应LTE移动回传、TDM和数据专线混合传送、IP和光网络协同组网等应用场景。在运营商和制造企业的积极推动下,我国通信标准化协会(CCSA)已完成了POTN的一系列行标制定工作,并在ITU-T SG15推进了现有标准建议完善。最后,对近期规模商用需进一步标准化的问题和面临的应用挑战进行了分析探讨。
Packet enhanced OTN integrates the technical advantages of PTN and OTN, and aims to realize the functional optimization and subtraction, to meet the requirements for the application scenarios of LTE mobile backhaul, hybrid transporting of TDM and Ethernet Line service, IP and optical network synergy. Under the promotion of Chinese operators and vendors, CCSA had carried out a series of research project and standard development work for POTN, and the relevant standards in ITU-T SG 15 had also been progressed. At last, the key technical issues for further research and some challenges for scale commercial deployment were analyzed and discussed.
