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
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

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.
