Stability analysis for global performance of flow control in high-speed networks based on statistical physics

This paper focuses on flow control in high-speed and large-scale networks. Each node in the network handles its local traffic flow only on the basis o f the information it knows. It is preferable, however, that the decision ma king of each node leads to high performance of the whole network. To this e nd, the relationship between local decision making and global performance o f flow control is the essential object. We propose phenomenological models of flow control of high-speed and large-scale networks, and investigate the stability of these models.
