Asynchronous Transfer Mode Switching at 622 Mb/s: A Multiservices QoS World

Overview While Asynchronous Transfer Mode switching was originally intended as a new protocol stack for LAN and WAN, operating at multiple layers in the Open Systems Interconnect stack, its workhorse application at 155-Mb/s (OC-3c/STM-1) rates has been as a transport-layer service, operating as an aggregator of packetized data traffic in the WAN backbone and in campus backbone networks of large enterprise networks. The mix of isochronous services with data transport underscores the worthwhile effort of the ATM Forum in developing multiple types of carrier services (Constant Bit Rate, Real-Time Variable Bit Rate, Non-Real-Time Variable Bit Rate, Unspecified Bit Rate, and Available Bit Rate) as well as the ATM Adaptation Layers meant for transport of the different services (AALs 1, 2, 3/4, and 5).

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
