A Next-Generation Network (NGN) is the term given to describe a telecommunications packet-based network that handles multiple types of traffic (such as voice, data, and multimedia). It is the convergence of service provider networks that includes the public switched telephone network (PSTN), the data network (the Internet), and, in some instances, the wireless network as well. * The NGN system offers key convergent multimedia services using a shared network characterized by several essential elements: * A unique and shared core network for all types of access and services. * A core network architecture divided into three layers: Transport, Control and Services. * Development of packet mode transport (IP flow transport in native IP, or on ATM in the short term with a progressive convergence to IP). * Open and standardized interfaces between each layer, and in particular for the Control and Services layers in order to allow third parties to develop and create s ...more

Next Generation Networking (NGN) is a broad term to describe some key architectural evolutions in telecommunication core and access networks that will be deployed over the next 5-10 years. The general idea behind NGN is that one network transports all information and services (voice, data, and all sorts of media such as video) by encapsulating these into packets, like it is on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term "all-IP" is also sometimes used to describe the transformation towards NGN.
