The aim of this research is to realize autonomous traffic management by using an adaptive routing control. In this paper, new router architecture is designed to the adaptive routing. In this technique, a router always supervises a traffic situation. Communication costs for every link are calculated based on the traffic situation. Scheduling of the transmitting route on the basis of the cost performs dynamic load distribution. The routers cooperate by the exchange of the control information added to the packet without preventing other communication in network. The adaptive routing control is performed autonomously. As the result, communication capacity is rearranged and connection situation is improved. Moreover, communication quality is improved by scheduling of transmission of packet. To evaluate the router and routing control software, simulation and its results are presented. Compared with routing via OSPF, this technique gives about 75% improvement of throughput in a LAN model.
