摘要:
A connection-oriented network (5) has a plurality of connections terminated at a first node (N6). A recovery group (A) is configured at the first node (N6) comprising at least two of the plurality of connections (LSP1-6, LSP2-6, LSP3-6, LSP4-6). Fault detection is performed over each of the connections in the recovery group (A) and the node determines if at least one recovery group fault condition is met, based on the results of the fault detections performed over the connections in the recovery-group (A). When the at least one recovery group fault condition is met, the node causes traffic on the plurality of connections in the recovery group (A) to be transferred to backup paths. When the at least one recovery group fault condition is not met, and a fault has been detected on a connection in the recovery group (A), the node causes traffic to be transferred from that connection to a backup path.
