Communication Network is evolving from a single service structure to multiple service structures. Technological development in telecommunication is leading us toward a unified backbone network called Next Generation Network (NGN). It is an IP-based packet network that provides QoS features while remaining independent of an access network. The services provided to users are independent of transmission architecture. NGN enables customers to receive different types of services like voice, data, and video over the same network. It simplifies the layered architecture and transforms the old legacy network into a packet-based architecture. The purpose of this article is to discuss the challenges and issues while the transition from legacy to IP-based packet networks and discuss the benefits of service providers in terms of business and service handling. NGN uses a new infrastructure to meet customer dynamic requirements. NGN service and NGN transport layer decoupling is the biggest challenge achieved by NGN infrastructure. This separation will result in the development of the core part and access part. It will increase the compatibility with multiple access networks.
