<p>PROBLEM TO BE SOLVED: To provide a communication controlling method and a network system whereby a high communication quality is realized even when voice, animation, etc., are included in the network system. SOLUTION: In switches SW1, SW2 and hosts H1, H2, H3 present in the network, when the summed frequency-band of a priority flow and a best effort exceeds a constant value, a priority is given to the priority flow by a priority control, and the frequency band of the best effort is regulated by a flow control. Therefore, such data as voice or animation which has priority can be transferred with a high quality without any disturbance, and a highly reliable communication can be provided.</p> |
