In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology comprising a plurality of routing arcs for reaching a destination network node; identifying, within the loop-free routing topology, non-congruent paths for a source network node to reach the destination node; and determining, from the non-congruent paths, a non-congruent path pair providing no more than a prescribed difference of latency from the source network node to the destination node, enabling the source network node to forward a data packet in a first direction of the one non-congruent path pair and a bicasted copy of the data packet in a second direction of the one non-congruent path pair, for reception of the data packet and the bicasted copy by the destination node within the prescribed difference of latency.
