开放和分解OTN技术研究和分析

Research and analysis of open and disaggregated optical transport network technology

如何构建开放和分解的OTN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,给出了自己的解决方案。本文对这两种技术方案做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做了简要的说明。

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,provide their own solutions respectively.This article makes in-depth research and analysis on these two technical solutions,and compares the similarities and differences between the two technologies,and briefl y explained the current development and application prospects of them.
