What is TDM

Next Generation Networks (NGNs) will accommodate heterogeneous architectures that need to be managed in order to provide services with high QoS to the users. The complexity of NGNs will give new challenges to network operators and service providers. The aim of this chapter is to present the complexity and the problems in the NGN management plane and to introduce a new framework that will solve many problems that operators face today. This chapter is separated in two parts. The first part presents the management architecture for NGNs according to ITU-T M.3060 recommendation. The second part introduces the concept of the Service Oriented Architecture (SOA) for managing the Next Generation Networks.
