IP Network Transformation

IP Network Transformation is the process of migrating TDM and ATM networks to a single, service-delivery oriented, end-to-end All-IP infrastructure. The evolution from legacy technologies to an End to End, Converged, IP based Network is the basis for IP Network Transformation. Convergence implies one network for all traffic. End to End implies IP everywhere, from Core to Access in the telecom operator space.

In wider sense Network Transformation consists of modernizing telecommunication network by offloading (migrating) customers from TDM/ATM based legacy systems to IP based systems. This, many a times, involves migration from copper to optical fiber.

Typical drivers for Network Transformation are lack of spares, lack of technical expertise in maintaining and operating the legacy networks leading to higher OPEX costs and degraded customer experience. On the other hand, migrating to IP based networks offers significant advantages such as Managed services, support, QoS, advanced features, reduced OPEX, to name a few.

Typical characteristic of Network Transformation is that it is usually initiated by the service provider rather than specifically requested by the subscriber (in essence the "network" is transparent to the user).
