摘　　要：针对当前我国光传送网(Optical Transport Network,OTN)网络覆盖不全,同步数字体系(Synchronous Digital Hierarchy,SDH)网络资源不足的现状,提出了一种OTN与SDH技术异构组网的方法,通过定义VC适配ODU帧结构,把STM-N封装到ODUk,达到运用OTN承载SDH业务的目的。通过实践应用,验证了SDH与OTN技术异构组网的可行性,对类似项目的顺利实施并达到预期目标有一定的参考意义和借鉴价值。Aiming at the current situation of incomplete Optical Transport Network(OTN)network coverage and insufficient Synchronous Digital Hierarchy(SDH)network resources in my country,a method for heterogeneous networking of OTN and SDH technologies is proposed.By defining VC to adapt to ODU frame structure,STM-N is encapsulated into ODUk to achieve the use of OTN.The purpose of carrying SDH services.Through practical application,this paper verifies the feasibility of heterogeneous networking of SDH and OTN technologies,and has certain reference significance and reference value for the smooth implementation of similar projects and achieving the expected goals.
