ITU-T G.8011.4 PDF

This Recommendation defines the service attributes and parameters for carrying Ethernet characteristic information over dedicated-bandwidth or shared-bandwidth, rooted multipoint connections, provided by SDH, ATM, MPLS, PDH, ETY, OTH or ETH server layer networks. This type of service is referred to as Ethernet private tree (EP-Tree) and virtual private tree (EVP-Tree) services. The initial focus of this Recommendation will be on uni-root and bi-root EP-Tree and EVP-Tree services. This Recommendation is based on the Ethernet service framework as defined in [ITU-T G.8011] and is aligned with the EP-Tree and EVP-Tree services specified in [MEF 6.1].
