Abstract: In one embodiment, a method comprises detecting a traffic condition by a network device in a loop-free routing topology comprising routing arcs for reaching a destination device, each routing arc comprising a first edge, a second edge, and at least a third network device configured for routing any network traffic along the routing arc toward the destination device and exiting via any one of the first or second edges of the routing arc, the traffic condition proximate to the first edge of at least one of the routing arcs in which the network device is positioned; and the network device initiating load balancing based on sending a management frame over a data plane of the at least one routing arc toward the corresponding second edge, the management frame requesting a change in load balancing for at least one of an identified traffic class based on the detected traffic condition.

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 load balancing the network traffic along the routing arcs based on traffic metrics obtained at the first and second ends of the routing arcs, including selectively sending a backpressure command to a first one of the routing arcs supplying at least a portion of the network traffic to a congested one of the routing arcs.
