Telecommunication Networks

8 Convergent Network Management and Control Plane

8.1 Introduction

In Chapter 2 we have seen that the main target of major telecommunication carriers is to decrease the operational expenditure (OPEX) necessary to maintain and operate the network. In Chapter 3 we have seen that there are different implementations of IP over optical architecture, but it is a fact that the old architecture made by two independent networks, one for data and one for telephone, has almost disappeared everywhere.

With the convergence of transport over one architecture, independently on the service bundles offered by the carrier to different categories of customers, also the division of the network management in two completely different architectures becomes inefficient: ...
