The International Telecommunication Union (ITU) has approved a set of global industry standards for Ethernet that the organization says will extend its flexibility and simplicity to carrier networks.

The standards outline a way for Ethernet to link any number of endpoints in a wide area network (WAN), or simply as a service delivery mechanism.

The news marks Ethernet’s progress from a LAN connectivity technology to a carrier class service delivery technology, the ITU said today.

The ability to offer Ethernet services means that carriers will be able to offer considerably improved flexibility to customers through a much simpler and lower cost interface. It will also allow users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered.

The work according to Peter Wery, chairman of the ITU Study Group responsible for the recommendations, is driven by common sense.

“Ethernet is the access interface of choice," he says. "It’s quite simply the most logical next step to extend its reach beyond the enterprise.

“This new set of recommendations describes Ethernet in a way that allows it to be deployed in a carrier network, over ATM, MPLS, SDH etc. It’s important because it provides end-users, from small and medium sized enterprises upwards, and service providers with a simple, cost-effective and yet robust and scaleable solution. This is exactly what the market needs.”
