Abstract(in English) In high-speed networks, it is impossible to exert time-sensitive control based on collecting global information about the network. This is because the processing speed of each node is high but the propagation delay is the same as in slower networks, which is constrained by the speed of light. So, in a high-speed network, the frameworks of time-sensitive control are inevitably autonomous decentralized systems. We have proposed an autonomous decentralized flow control mechanism applicable to high-speed networks. Each node in a network handles its local traffic flow only on the basis of the information it is aware of, but it is preferable that the decision-making of each node leads to high performance of the whole network. In this article, to clarify the aim of our flow control mechanism, we show explanations from the following three points of view: (i) layered structure of network control, (ii) the relationship between local decision making at a node and the performance of the whole network, and (iii) the principle of our flow control derived from the efficient framework of parallel computing.
