In one example, a method and apparatus for optimizing a software defined network configuration are disclosed. In one example, the method determines a first network relative performance parameter for a current configuration of a network, based on respective weighting profiles associated with services for which the network carries data. The method then determines a second network relative performance parameter for a proposed configuration of the network, based on the respective weighting profiles associated with the services for which the network carries data. The proposed configuration is implemented in the network when the second network relative performance parameter is greater than the first network relative performance parameter.
