Abstract
In an example embodiment, packets for a selected flow are replicated and sent over one or more diverse paths, such as a primary path and at least one secondary path, to a destination switching device. At the destination switching device, one copy of the replicated packets is selected for delivery to the destination, and the remaining copies are discarded. In the event that packets are not received at the destination switching device due to loss of connection on the primary path or packets are not timely delivered due to congestion on the primary path, a different path may be selected as the primary path.
