开放和分解OTN网络技术研究和分析

如何构建开放和分解的OTN网络，以实现跨厂家设备的混合组网和光层互连，一直是运营商和设备商追求的目标，ONF和LFN这两大开源项目组织分别基于各自的SDN控制平台——ONOS和OpenDayLight，给出了自己的解决方案——ODTN+TAPI和OpenROADM+TPCE，本文对这两种技术方案作了深入的研究和分析，比较了这两种技术的异同点，并对当前这两种技术的发展和应用前景作了简要的说明。

Research and Analysis of Open and Disaggregated Optical Transport Network Technology

How to build an Open and Disaggregated Optical Transport Network to achieve hybrid networking and optical layer interconnection of cross-vendor domain has always been the goal pursued by operators and vendors. ONF and LFN, are based on their respective SDN controller platforms, i.e.ONOS and OpenDayLight, provide their own solutions respectively, ODTN+TAPI and OpenROADM+TPCE. This article makes in-depth research and analysis on these two technical solutions, and compares the similarities and differences between the two technologies, and briefly explained the current development and application prospects of them.
