Ericsson solution ensures reliable IP services

Ericsson solution ensures reliable IP services - Telia first operator to trial Ericsson's WDM (Wavelength Division Multiplexing) has gone live in trials with operator Telia. The trials mark the first implementation of a new solution to ensure reliable transport of IP services, as well as signal a strengthening of Ericsson's position with Telia in the area of transport networks. Ericsson's unmatched solution for reliable transport of IP and other datacom traffic ensures delivery of high-quality services. At the same time it significantly reduces cost of operation and safety in optical networking for operators entering the New Telecoms World. The new safety solution with optical self-healing rings, called the FlexingBus, is the latest addition to Ericsson's WDM offering ERION (Ericsson Optical Networking), enabling operators such as Telia to provide highly reliable, high-capacity IP services. These are services driven by the rapidly growing amount of Internet and datacoms traffic, reflecting the increasing sophistication of operator and user requirements. With these services travelling at the speed of light - or some 200,000 kilometers per second inside the optical fiber - full safety in networks is essential for handling fast-growing IP traffic. The Ericsson FlexingBus solution incorporates highly sophisticated fiber optic technology that makes it possible to re-route traffic in less than 20 milliseconds. BT, o-tel-o, Sonera and Telefonica are four major European operators that are implementing Ericsson's WDM solutions. Over 100 operators of wireline networks in more than 80 countries use transport networks from Ericsson. Furthermore, the company has supplied its MINI-LINK wireless transport solutions to operators in more than 100 countries. Ericsson is the leading provider in the new telecoms world, with communications solutions that combine telecom and datacom technologies with freedom of mobility for the user. With more than 100,000 employees in 140 countries, Ericsson simplifies communications for its customers - network operators, service providers, enterprises and consumers - the world over.

The solution brings down the cost for transporting universal traffic types, making it easier and more practical for operators to offer high-quality IP services. On a global scale, Ericsson's WDM solutions are advantageous not only for well-established operators, but also for new operators. To transport services WDM uses multiple wavelengths, or colors of light that are fired down a fiber. Each wavelength is a separate channel - which multiplies traffic capacity in existing fiber, thereby providing operators with nearly limitless bandwidth without having to lay new fiber. Ericsson's WDM offers much more than the opportunity to expand existing fiber capacity; it is designed to be a new kind of network architecture that is cost saving for operators. It simplifies an operator's network by creating layers of self-protecting optical rings. Each ring layer can carry a mix of traffic using different wavelengths. The FlexingBus safety feature means that within each fiber ring one segment can be deactivated, turning the ring into a 'bus'. This solves the problem of recirculating traffic. The location of the inactive ring segment can be shifted around the ring, to create different bus configurations - hence the name. With this concept, Ericsson simplifies network architecture by creating a hierarchy of self-protecting optical network rings, where traffic is re- routed in less than 20 milliseconds.
