1. A method for modifying a priority for at least one flow class of an application, the method comprising:

  • registering flow classes for the application with a software defined networking (SDN) controller, wherein the flow classes comprise a description of flow modification rules and a priority at which the flow modification rules are to be installed at a switch;

    determining, with the SDN controller, a priority for each of the flow classes based on other installed applications and network services on the SDN controller;

    modifying, based on an event, the priority for at least one of the flow classes of the application by mapping a priority key associated with the priority to a new priority value;

    receiving, from the application, at least one flow modification rule using the priority key as the priority; and

    validating the at least one flow modification rule against registered parameters of at least one of the flow classes of the application to determine a flow of traffic based on the priority.
