A data burst assembly apparatus includes a receiver to receive a packet from at least one source; a monitor to monitor a data traffic condition of a network; and a data burst generator to dynamically determine a value of a generation parameter for generating a data burst with respect to the packet received at the receiver according to the data traffic condition of the network, and to generate the data burst using the generation parameter value. A storage unit may be further included to store a mapping table defining generation parameter values mapped based on data traffic conditions. A data burst generator can read a generation parameter value mapped to a monitoring result from a mapping table and generate a corresponding data burst.
