From the ITU-T Newslog: A meeting of Study Group 15, the ITU-T group responsible for studies into optical and other transport network technologies, has consented 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 ITU Ethernet standards approved last year. See this ITU press release from 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.
