Next-Generation Network Last modified: Thursday, January 26, 2006
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 services independent of the network. Support for multiple applications (multimedia, real-time, transactional, total mobility) adaptable to the user and growing and varied capacities of access networks and terminals. * [Adapted from Moving towards the Next Generation Networks (NGN)]

In-depth articles and news cover topics such as network management, network monitoring, servers, communications, Internet telephony, operating systems, and much more. France Telecom: Tomorrow's Network for Voice and Data NGN, or Next Generation Network, is a new communication network architecture. The principle is to use packet mode transmission technologies, reserved up till now for data, to transport all the various types of telecommunication services. NGN Initiative Web site The NGN Initiative's mission is to establish the infrastructure to operate the first open environment for research on the whole range of Next Generation Networks (NGN) topics to be discussed, consensus achieved and collective outputs disseminated to the appropriate international standards bodies, fora, and other organizations. Telcordia Technologies - NGN Services (PDF) Intense competition is expected in the information networking arena over the next 5-10 years. As the competition increases, it will be essential for companies to position themselves appropriately to take advantage of their core competencies and to prepare for the emerging telecommunications environment.
