Traffic Control Scheme under the Communication Delay of High-speed Networks

In this paper, we discuss the concept ofmultia4gent systems as applied tohigh-speed n twork traffic control. In the high-speed domain, the propagation delay in a network causes ignificant problems. One of them is that any centralized control is too late to maintain normal network operations, so distributed ra~c control by autonomous agents is required. The basic idea of our traffic control for high-speed n tworks i a combination of distributed local control and centralized global control; that is, bcfore the global control becomes effective, Mlnetwork nodes try to maintain their operations in cooperation with other nodes. The significance of propagation delay in such networks requires that he communication delay is included inthe model of the node ~gents. This paper proposes a multiagent traffic control and illustrates heexperimental results. The results show that the control based on the multiagent system can improve the efficiency of network control.
