Abstract:
In one embodiment, a device in a mesh network joins a source-destination oriented partial directed acyclic graph (SDO-PDAG) between a source node and a destination node in the network. The device receives operations, administration and maintenance (OAM) packets flooded along reverse paths of the SDO-PDAG. The device determines, based on the received OAM packets, packet drop rate (PDR) capacities of different paths between the device and the destination node. The device replicates a data packet sent from the source node to the destination node along two or more of the paths between the device and the destination node, based on the determined PDR capacities of those paths.
