  • Patent number: 11916674
    Abstract: Embodiments herein disclose conditioning traffic through multiple data paths of a Software-Defined Wide Area Network (SD-WAN). Some embodiments include monitoring a path through an SD-WAN to reach a destination node, determining a quality score for packets to the destination node on the path, determining a link utilization for the path, sending a data packet sequence to the destination node on the path, generating a forward error correction (FEC) packet for the data packet sequence, and sending the FEC packet to the destination node on the path in response to the quality score being less than a quality threshold and the link utilization being less than a high utilization threshold.

  • Patent number: 11827965
    Abstract: A metallic glass coating material is composed of an alloy of Fe, B, and one of the metals Nb, Mo, Zr, or W. The ratios of Fe, B, and the metal are predetermined using machine learning predictions and high-throughput experiments. In one example, the material is an alloy of Fe, Nb, Mo and B, of the form Fex(Nb, Mo)yBz, where x is in the range 18-28, y is in the range 35-45, and z is in the range 32-42. In another example, the material may be the alloy Fe23(Nb, Mo)40B37. The alloy may be doped with Zr and/or W, where the Zr and/or W comprises at most 10% of the alloy.
