CONTINUITY CHECK MANAGEMENT IN A LINK STATE CONTROLLED ETHERNET NETWORK
摘要
<p>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 using an 802 lag 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 A method of 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 It then executes one or more Ethernet OAM commands from the node to ascertain the data plane topology view o 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</p>
