This paper presents a span-ring transport mechanism for multiple resilient packet rings based on GMPLS. The simulation
result shows that this approach can be used to achieve transparent and reliable transportation of the span-ring services in
the RPR multi-ring network.
With the help of an independent control plane, ASON introduces lots of new intelligent functions into the traditional transport network. We use some special protocols such as signaling and routing protocols in control plane instead of network management protocol that only has few primitives to control the network elements in transport plane. During the service provision of ASON, the coordination of management plane (MP) and control plane (CP) is very important. This paper analyses the coordination of MP and CP of ASON. At first, it introduces the meaning of coordination between MP and CP and its classification. Secondly, it puts emphasis upon analyzing traffic engineering (TE) realized through the coordination of MP and CP. In this part, we modify the basic ASON routing architecture and introduce the coordination functions of MP. Thirdly, this paper analyses TE control processes of the coordination between those two planes during the services provision which has not been considered in ASON recommendations but is very important.

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.
