Abstract: A method for selecting a transmission of a network device is disclosed. In particular, a method for selecting a transmission of a network device comprising a plurality of queues for storing data frames is disclosed. Here, each of the plurality of queues corresponds to a different traffic class, the method comprising: a step of obtaining information about a transmission selection algorithm for the plurality of queues; and a step of selecting data frames for transmission from a corresponding queue on the basis of transmission selection algorithm information. Here, the transmission selection algorithm may correspond to a strict priority algorithm, a credit-based shaper algorithm, or a burst transmission algorithm.
