Abstract In multimedia communication, where media data with various requirements for the delay quality are transmitted through the multinode network, it is desirable to apply a priority control method according to the nature of the media. This paper proposes a new priority control method whereby the delay quality of each medium is evaluated by the fuzzy satisfaction, and the priority is adjusted through the feedback of the delay quality. The performance of the system is examined by a simulation. In the proposed system, the delay time is observed for each origination/destination pair at the destination node, and the fuzzy satisfaction of the delay quality is determined. The average satisfaction of the whole system is determined. Then the priority is renewed according to the difference between the satisfaction for each origination/destination pair and the average satisfaction of the system. It is shown that by the proposed method, the delay quality of the whole system is made almost uniform.
