Abstract
A system and method of protection switching in a communications network that makes more efficient use of resources in the network and reduces the loss of data traffic carried by the network. The communications network includes an established working path and an established protect path interconnecting a source node and a sink node. The source node and the sink node are configured to perform label switching on the network. The source node receives primary data traffic and secondary data traffic over one or more communications paths. In a fault-free condition, the source node sends the primary data traffic over the working path to the sink node, and sends the secondary data traffic over the protect path to the sink node. In the event of a fault or switchover condition in the working path, the source node performs traffic trunk and label merging on the primary and secondary traffic, and sends the merged traffic over the protect path to the sink node.
