Abstract: 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 device, each routing arc comprising a first network device as a first end of the routing arc, a second network device as a second end of the routing arc, and at least a third network device configured for routing any network traffic along the routing arc toward the destination device via any one of the first or second ends of the routing arc; and causing the network traffic to be forwarded along at least one of the routing arcs to the destination device.

Abstract: In one embodiment, a method comprises promiscuously detecting, by a network device in a wireless data network having a tree-based topology for reaching a root device, a wireless data packet transmitted by a source network device and specifying a destination device in the wireless data network; determining, by the network device, that the destination device is within a first sub-topology provided by the network device to reach the root device, wherein the source network device is within a second distinct sub-topology provided by a parent device of the source network device to reach the root device; and causing installation of a bypass path, bypassing the root device, based on the network device generating and transmitting an instruction to the parent device to install a route entry causing a data packet destined for the destination device to be routed by the parent device directly to the network device.
