摘要： Methods and apparatus provide for a network device(s) employing tree tracer processing of a data packet(s) and/or a response(s) in order to discover and graphically represent all the paths within a hierarchical tree of network devices for multicast traffic flows. Specifically, a first network device receives a data packet. The data packet provides a multicast target MAC address. The first network device forwards the data packet to a plurality of network devices, where each of the plurality of the network devices belong to a multicast group identified according to the multicast target MAC address. Based on receipt of the data packet, the first network device generates and transmits a first response to a source of the data packet. The first response indicates a placement of the first network device with respect to a hierarchical tree of the plurality of network devices belonging to the multicast group.

摘要： Network and performance monitoring in a link state protocol controlled Ethernet network. A first node receives a network layer monitoring command from a network layer monitoring requestor. The monitoring command is directed to a second node. The first node resolves the network layer monitoring command into one or more Ethernet OAM command(s); The first node sends the Ethernet OAM command(s) to the second node, receives the results of the Ethernet OAM command(s) from the second node; and returns the results of the Ethernet OAM command(s) in the form of a network layer response to the network layer monitoring requestor. Furthermore, network layer monitoring commands may be one or more performance monitoring commands, and the Ethernet OAM commands can include Y.1731 commands. An IP flow can be adjusted between the first node and the second node in response to the network layer response returned to the network layer monitoring requestor.
