• 論文抄録 / 内容記述: The dynamic nature of high-speed networks posesdifficult traffic control problems when trying to achieveefficient use of network resources. One such problemis the issue of bandwidth management allocation.Because of the statistical multiplexing of all connectionsand the variation of connections bit rates it is importantto evaluate the equivalent capacity of all connections.The purpose of the equivalent capacity is to providea metric to represent the effective bandwidthused by connections and the corresponding effective loadon network links. In order to cope with rapidly changing network conditions traffic control methods for high-speed networks must be adaptive flexible and intelligent for efficient network management.Use of intelligent methods based on fuzzy logic neural networksand genetic algorithms can prove to be efficient for trafficcontrol in high-speed networks.The equivalent capacity estimation is a very important functionfor call admission control. To estimate the equivalentcapacity fluid flow approximation stationary approximationand equivalent capacity method has been proposed.But they make many approximations which result in an overestimate of equivalent capacity.In this paper we propose a fuzzy equivalent capacity estimatorfor bandwidth allocation in high-speed networks.Performance evaluation via simulations shows that proposedfuzzy equivalent capacity estimator has a good equivalent capacityestimation compared with fluid flow and stationary approximations.Furthermore the combination of fuzzy equivalent capacity estimator and stationary approximation give a better estimation compared with Guerin's method.
