Next Generation Networks (NGN) is a strategy to achieve the vision of next-generation services for the delivery of quad play data, voice and video anywhere and anytime virtually across any access technology. It integrates the services of 2G/3G/4G networks including IPv4 and IPv6 and incorporates the services of traditional networks into a single service platform with the usage of Multi-Protocol Label Switching (MPLS). Much work has been reported by researchers to integrate MPLS technology into IP networks. But, not much progress has been made so far.
