摘　　要：对SDH技术以及基于SDH的多业务传输平台MSTP的主要特点进行了概述,着重分析了多业务传输平台中的VC级联、链路容量调整机制、通用成帧协议、多协议标记交换及弹性分组环等关键技术,并对采用核心技术前后的传输效率进行了比较,在研究了城域传输网现阶段主要应用的基础上分析其发展动态,提出了其在自动交换光网络等层面实现互通的趋势。Main characters of multi -services transport platform and synchronize digital hierarchy technology are studied in this paper. Visual concatenation, link capacity adjustment scheme, generic framing procedure, multi - protocol lahel switching and resilient packet ring of MSTP are analyzed emphatically. Transport efficiency before and after using these techniques are compared. Current application and developing of MSTP are introduced. Then trend of realizing connecting in ASON layer and other aspects is proposed.
