This paper discusses and analyzes the designing of SDH embedded with RPR and its applications in MAN. The main contents of this paper include: First of all, we discuss the disadvantages of the traditional Ethernet module embedded in SDH node while it carrying dada service in perspective of network organization, of QoS guarantee and network security. Secondly, we introduce the designing of SDH embedded with RPR, which can resolve the above problems. And finally, this paper puts emphases on analyzing the application models of this kind of SDH nodes in the metro area transport network, and the performance optimization for data services provided by the nodes.
