APPARATUS AND METHOD FOR EXTIMATING NETWORK BANDWIDTH IN COMMUNICATION SYSTEM

摘要

The present invention relates to predict a network bandwidth of a communication system. A transmission device of the communication system comprises: a control unit for determining whether the time to be sending packet train for the prediction of the network bandwidth arrives, and generating the packet train including a real-time traffic; and a communication unit for transmitting the packet train.
