基于SDN的OTN和UTN网络融合技术研究

Research on OTN and UTN Network Fusion Technology Based on SDN

网络技术的开发日新月异,各种不同功能的信息技术不断被研发,并且被应用在各个不同的行业中。软件定义网络(Software Defined Network,SDN)是基于SDN技术、区块链技术、云计算、边缘计算打造的“云-边-端”结合的去中心化网络,可以为各种类型的应用提供关键性的数据、网络、计算支撑能力。提出一种基于SDN的光传送网(Optical Transport Network,OTN)和综合业务光传输网(Universal TransportNetwork over Fiber,UTN)融合技术,致力于实现城域OTN和UTN混合组网时在端到端操作维护管理(Operation Administration and Maintenance,OAM)、保护倒换等方面的协同。对SDN进行了简述,分析了OTN和UTN融合需求、OTN与UTN的渐进式融合方案以及转发与控制分离式融合方案。

With the rapid development of network technology,various information technologies with different functions are constantly being developed and applied in various industries.Software Defined Network(SDN)network is a decentralized network based on SDN technology,blockchain technology,cloud computing,and edge computing ability.An SDN-based Optical Transport Network(OTN)and Universal Transport Network over Fiber(UTN)network convergence technology is proposed,which is dedicated to realize the coordination of end-to-end Operation Administration and Maintenance(OAM),and protection switching,etc.in the mixed networking of metro OTN and UTN.The SDN is briefly described The convergence requirements of OTN and UTN,the progressive convergence scheme of OTN and UTN,and the split forwarding and control convergence scheme are also analyzed.
