What is a Next Generation Network ?

Todays Telecom Networks Next Generation Networks

n Multiple service-specific access nodes

n Multiple service-specific core networks

Converged access nodes aggregate trafficfrom multiple access services

A converged IP-based core networkcarries this traffic

Service intelligence is decoupled fromnetwork transmission
