Abstract
A root node associated with an Ethernet-Tree (E-Tree) service sends, over a rooted-multipoint Ethernet virtual connection (EVC), a performance monitoring (PM) packet, where the PM packet includes a unique identifier for the root node and a time sent by the root node. The root node receives, from leaf nodes and a root point associated with the E-Tree service, PM response packets, where each PM response packet includes a unique identifier for the responding leaf node/root point and a time received by the responding leaf node/root point. The root node extracts, from each of the PM response packets, the unique identifier and the time received, and stores performance measurements based on the extracted data, where the performance measurements are associated with the respective leaf nodes/root point.
