摘要： A technique for status change handling in an interconnect node is described, wherein the node comprises a data plane that can assume, per service, a passive or active status. A method aspect in the node comprises transmitting, to another node, a first indication that a change has been or is about to be performed, awaiting, from the other node, reception of a second indication that the data plane in the other node has been set to the passive status, and activating, responsive to the received indication, the data plane of the node from the passive status to the active status. The method aspect in the other node further comprises receiving, from the node, the first indication, passivating, responsive to the receiving step, the data plane being in the active status to the passive status, and transmitting, upon completion of the passivating step, the second indication.

摘要： Methods and apparatus are disclosed for applying multiple Link Aggregation Group (LAG) entities on the same set of physical links, thus making bundling of individual services or conversations possible by the different LAG entities within Link Aggregation. Each LAG entity is configured such that a single physical link is Active and all the other links are Standby. Each LAG entity may be regarded as a “bundle.” Thus the services/conversations are bundled into a LAG entity and are handed-off on the Active link during normal operation. If service hand-off is not possible on the Active link (e.g., due to a failure), then the LAG entity switches over to a Standby link thus the service/conversation is handed-off on that formerly Standby link. Bundling may simplify operations of control and signaling.

摘要： A pseudowire redundancy network comprises a plurality of pseudowires (PW13, PW 14) attached to a provider edge node (201). For selecting an active pseudowire (PW13) to be used for forwarding user traffic, the provider edge node (201) determines a local preferential forwarding status for each of the pseudowires (PW13, PW14). The determined preferential forwarding status is active for no more than one of the pseudowires (PW13, PW14). The provider edge node (201) indicates the determined local preferential forwarding status of the pseudowires (PW13, PW14) to remote provider edge nodes (203, 204). Further, the provider edge node (201) receives indications of a remote preferential forwarding status for each of the pseudowires (PW13, PW14) from the remote provider edge nodes (203, 204). The provider edge node (201) then selects that one of the pseudowires (PW13, PW14) as active for which both the local preferential forwarding status and the remote preferential forwarding status is active.
