Coordination of management plane and control plane of ASON

Abstract

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.
