Recommendation ITU-T G.8011.4/Y.1307.4 defines the service attributes and parameters for carrying Ethernet characteristic information over dedicated-bandwidth or shared-bandwidth, rooted multipoint connections, provided by SDH, PDH, ATM, MPLS, OTH, ETY or ETH server layer networks. This type of service is referred to as Ethernet private tree (EP-Tree) and Ethernet virtual private tree services. This Recommendation is based on the Ethernet service framework as defined in Recommendation ITU-T G.8011/Y.1307.
