Abstract:
1. A method performed by one or more devices in a metro Ethernet network, the method comprising: sending, by a root node associated with an Ethernet-Tree (E-Tree) service and over a rooted-multipoint Ethernet virtual connection (EVC), a performance monitoring packet, where the performance monitoring packet includes a unique identifier for the root node and a time sent by the root node; receiving, by the root node and from one of a plurality of leaf nodes associated with the E-Tree service, a performance monitoring response packet, where the performance monitoring response packet includes a unique identifier for the one of the plurality of leaf nodes and a time received by the one of the plurality of leaf nodes; extracting, by the root node and from the performance monitoring response packet, the unique identifier for the one of the plurality of leaf nodes and the time received by the one of the plurality of leaf nodes; and storing, by the root node, performance measurements based on the extracted data, where the performance measurements are associated with the one of the plurality of leaf nodes.
