Abstract: In one embodiment, a device in a network detects a bidirectional traffic flow along a primary path in the network. The device determines that a self-interference condition exists along the primary path. The device selects an alternate path in the network. The device causes the traffic flow to use the primary path for packets of the traffic flow sent in a first direction and to use the alternate path for packets of the traffic flow send in a second direction that is opposite that of the first direction.

Abstract: In one embodiment, a method includes: receiving, at a device of a computer network, a request to build at least part of a backup directed acyclic graph (BDAG) of backup devices for routing traffic within the computer network in case of a power outage, the request comprising at least one requirement specifying to use a device remaining powered after the power outage as a backup device; and in response to receiving the request: identifying a set of backup devices, each of the backup devices fulfilling the at least one requirement; selecting a backup device from the set of backup devices; and synchronizing the device with the backup device according to a backup operation strategy received from the backup device.
