Next Generations Networks (NGN) are huge packet switched data communications networks, the traditional telecoms infrastructure becomes one large computer network looking more like WANs and LANs. It will become much easier for third parties to develop and link services to this infrastructure, as infrastructure and services will be totally separate from each other, which will allow for the literally millions of new services offered by hundred of thousands of service providers. These networks already exist in the corporate environment and will start reaching mass markets within the next 5 to 10 years. Think of NGNs as the Internet with its tens of millions of Websites.
It will be a QoS multiple-broadband network and will also support seamless mobility providing users with a ubiquitous provision of services.
It will be a totally IP based infrastructure which means standardised, cheap and open access. IP addressing will bring in not just people and computers to the network but also cars, fridges, every single power point in the house and so on.
A lot of attention is currently given to VoIP, but voice will simply be one of the millions of applications on this network, voice as such which will hardly register on these multi giga- or terra bites networks. However, VoIP offers us a glimpse of the future, it is a first example of that process of standardisation, cheap and open access and will be a key driver in competition. VoIP will only come to full fruition in triple play business models that will be marketed over the broadband networks; bundling voice, high-speed Internet and video services such as broadband TV.
