1. A method for processing a traffic frame in a communication network using a software defined network (SDN) controller, comprising:
instantiating, by the SDN controller, a virtual network function;
determining, from the virtual network function, that a first incoming traffic frame at the virtual network function is carrying data traffic;
in response to determining that the first incoming traffic frame is carrying data traffic, determining a bandwidth profile of the first incoming traffic frame; and
identifying a quality of service (QoS) level of the first incoming traffic frame, according to the bandwidth profile of the first incoming traffic frame.
