Abstract
Information networks are an important infrastructure and their resources are shared by many users. In order to utilize their resources efficiently, they should be controlled to prevent synchronization of user traffic. In addition, fairness among users must be assured. This paper discusses the framework of transmission rate control based on chaos. There are two different characteristics that coexist in chaos. One is that the state in the future is extremely sensitive to the initial condition. This makes it impossible to predict the future state at a fine level of detail. The other is the structural stability of macroscopic dynamics. Even if the state is uncertain on the microscopic scale, state dynamics on the macroscopic scale are stable. This paper proposes a novel framework of distributed hierarchical control of transmission rate by interpreting the coexistence of chaos as microscopic fairness of users and macroscopic stable utilization of networks.
