This Recommendation defines the service attributes and parameters for carrying Ethernet characteristic information over shared-bandwidth, point-to-point connections, provided by SDH, ATM, MPLS, PDH, ETY, OTH, or ETY server layer networks. This type of service is referred to as Ethernet Virtual Private Line (EVPL) service.The Recommendation is based on the Ethernet service framework as defined in ITU-T Rec. G.8011/Y.1307 and is aligned with the EVPLspecified in MEF 6.1.
