  • Patent number: 11770350
    Abstract: The present disclosure is directed to adaptive networking policy with user defined fields and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more components to perform operations including generating a user defined attribute (UDA) value corresponding to a set of attributes; receiving, at a network device, a packet having one or more packet conditions; determining that the one or more packet conditions of the packet match the set of attributes of the UDA value; assigning a UDA tag to the packet, wherein the UDA tag corresponds to the UDA value and is configured for chaining with one or more other UDA tags; and taking an action on the packet based on the UDA tag.

  • Patent number: 11627111
    Abstract: The present technology discloses systems, methods, and computer-readable media to establish at least one target for a network, the target including at least one of an ingress parameter or an egress parameter and a policy for network packets; receive at least one network packet on the network; search for at least one matching target from the at least one targets, the at least matching target comprising parameters that match the at least one network packet; apply a policy in the at least one matching target to the at least one network packet; and forward the at least one network packet in accordance with the policy.

  • Patent number: 9758597
    Abstract: The invention provides methods of reducing shrinkage stress in cross-linked polymerized materials by combining an addition-fragmentation chain transfer additive with a resin system prior to polymerization. The methods of the invention can improve the performance of conventional resin systems by reducing the shrinkage stress without significantly degrading the mechanical properties of the polymerized material. The shrinkage stress in the crosslinked polymeric materials produced by the methods of the invention may be from 25% to 75% of that of a control material produced by polymerization of the resin system alone to the same conversion.

  • Patent number: 8877830
    Abstract: The invention provides methods for inducing reversible chain cleavage of polymer chains in a crosslinked polymeric material or during polymerization of a polymeric material. Reversible cleavage of the polymer backbone is capable of relieving stress in the polymeric material as the bonds reform in a less stressed state. The invention also provides mixtures for making crosslinked polymeric materials, methods for making polymeric materials capable of reversible chain cleavage, materials made by the methods of the invention, and linear monomers containing reversible chain cleavage groups which are useful in the materials and methods of the invention. The mixtures of the invention may be dental restorative compositions used for forming dental restorative materials.
