US Patent 9887874 Soft rerouting in a network using predictive reliability metrics

In one embodiment, a plurality of paths in a network from a source device to a destination device is identified. A predicted performance for packet delivery along a primary path from the plurality of paths is determined. The predicted performance for packet delivery along the primary path is then compared to a performance threshold. Traffic sent along the primary path may be duplicated onto a backup path selected from the plurality of paths based on a determination that the predicted performance along the primary path is below the performance threshold.
