摘要
在广泛使用基于同步数字体系(SDH)的多业务传送平台(MSTP)的基础上,引入基于密集波分复用(DWDM)系统的光传送网(OTN)。在接入层采用MSTP解决业务的送达与环网的保护,在汇聚乃至骨干层采用OTN解决大颗粒业务的传送需求。该设计方案将两种截然不同的传输网络机制有机结合,为转型中的移动通信运营商在原有MSTP网络基础上快速实现大流量、大带宽的业务开通创造了条件。
On the basis of the widely used SDH-based MSTP,the DWDM-based OTN is introduced.In the access layer,MSTP is used for service delivery and ring net protection,while in the convergence or even backbone layer,OTN is used for the transfer of large granular services.In this design,two entirely different transfer network mechanisms are integrated to create conditions for mobile telecom carriers to fast realize large flow and bandwidth services on the basis of MSTP networks.
