A meeting of Study Group 15, the ITU-T group responsible for studies into optical and other transport network technologies, saw consent on a new Recommendation that defines the way for equipment providers to produce systems for Ethernet virtual private line (EVPL) services.

EVPLs offer a way for operators to provide point-to-point connections for carrying data over shared-bandwidth facilities.

The announcement is in line with the current industry trend to offer Ethernet services, and further signals Ethernet's growth in popularity as an enterprise telecom service.

Long-recognized as a ubiquitous LAN technology, Ethernet is now seeing increased attention as a carrier-grade service. In part this is due to the convenience of being able to simply provide end-to-end service, but also carriers can realize savings both in terms of capital and operational expenditure.

In terms of capital expenditure, Ethernet is easy and cost-effective to provision in the network. In terms of operational expenditure, carriers can deploy a single physical connection to the end user, but adapt its data-carrying capacity as end-user requirements dictate over time. This flexibility means a significant saving for the operator and the customer.

This work follows earlier work in the area of Ethernet standards approved last year. See also press release 8 June, 2004.

The new Recommendation - G.8011.2 - defines the service attributes and parameters for carrying Ethernet characteristic information over shared-bandwidth, point-to-point connections, provided by SDH, ATM, MPLS, PDH, OTH, or ETY server layer networks.
