摘要： An OAM link trace message is sent from a source node to a target node in a link state protocol controlled Ethernet network. The link trace message uses an 802.1ag format except, as a destination address, it uses either the unicast Ethernet MAC node ID of the target node or the multicast destination address of the service instance. Network topology verification in a link state protocol controlled Ethernet network checks the link state protocol database at a node to ascertain the control plane topology view of at least part of the network. One or more Ethernet OAM commands from the node are executed to ascertain the data plane topology view of the same part of the network. The control plane topology view of the network is compared to the data plane topology view of the network to see if they match. An error is flagged if they do not match.

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.
