  • Patent number: 9755959
    Abstract: Presented herein are techniques for dynamic creation of a unique service path for a service chain. In one example, a service controller and a plurality of service nodes are provided, each service node configured to apply a service function to traffic that passes through the respective service node. The service controller defines a service chain identifying a set of service functions and an order in which they are applied. The service controller receives an indication that the service chain has been instantiated at a classifier, and creates a unique service path for the service chain, wherein the unique service path includes the service chain and the classifier at which the service chain is instantiated.

  • Publication number: 20170051383
    Abstract: The present disclosure relates to aluminum based alloys and a method for producing the aluminium based alloys. The method comprises acts of, casting of the aluminium based alloy in a chilled casting mould. Then, aging the cast aluminium based alloy at a first predetermined temperature for a first predetermined time. The aging results in the formation of a first precipitate. Followed by this, solutionizing the aluminium based alloy at a second predetermined temperature for a second predetermined time such that the major alloying element is dissolved in aluminium matrix without much affecting the first precipitate. Then, aging the aluminium based alloy at a third predetermined temperature for a third predetermined time. The aging results in the formation of a second precipitate.
