An introduction to NGNs |
An NGN (Next Generation Network) is a universal
multi-service network designed for the transmission of voice,
images and data on a packet switching basis. An NGN provides the
quality of service necessary for different types of telecommunication
traffic. Characteristically, the transmission and the routing
of the packets and the elements of the transmission equipment
(links, routers, switches, gateways) are physically and logically
separated from the devices and the intelligence controlling the
execution of calls and services. The network intelligence supports
all types of services in the packet network, from basic voice
telephony to data, image, multi media, broadband and management
applications.
These features represent the basis for drawing a distinction between
an NGN and an ordinary telephone and IP network, which otherwise
prevail in telecommunications. An NGN, the result of merging the
internet with the telephone network, combines the best features
of both. It provides:
• Adaptability for transmitting any type of traffic, which
can be compared to the internet's adaptability as opposed to the
inefficiency of a PSTN in transmitting data (this fact is especially
important with regard to the estimation that data will soon represent
90% of telecommunication traffic).
• Guaranteed quality of voice telephony services and critical
data applications; in this case an NGN offers PSTN reliability
as opposed to the »best effort« of the internet's
capacity.
• Low transmission costs per content unit - the price is
closer to the internet than to a PSTN, the total amount of data
and voice traffic trebles every year.
Teralight has focused its product line on delivering this value
proposition to address the critical themes essential to most carriers:
the ability to deliver comprehensive solutions that are both capital
and operationally efficient, and also have a proven track record
in the market. |

NGN Architecture
|
• Transmission, linking, routing and services in legacy networks are integrated vertically: different networks are designed for different services (telephony, video, data). In contrast to legacy networks, next generation networks (NGNs) are characterized by an open architecture and the horizontal connection of different layers:
• The common NGN infrastructure is implemented with the transport layer, which is based on packet technology and used by different services. Information transfer between the source and the destination is transferred in an identical way, irrespective of whether it is a telephone call, an internet session, a video connection, a game with several players, or a movie.
• The application service layer is logically and physically separated from the transport layer, which enables the independent development of particular network segments. Different servers, which are separated from the transport, control different services - these include voice telephony, e-commerce, video-on-demand, etc. Adding a new service requires only a new server, which, via the transport layer, is accessible to all users connected to the network.
• Users connect to an NGN over interfaces that have different bandwidths and are implemented with different technologies. Despite broadband interfaces (>0.5 Mb/s) being the most suitable for connecting with anNGN, users have universal access to services irrespective of the type of equipment used.
