Abstract
A large-scale direct interconnection network usually consists of enormous number of simple routers. However, its behavior is sometimes very complicated. Such a complicated behavior prevents us from accurate understanding and efficient control of the network. Among serious problems in interconnection networks, congestion control is of extreme importance since network performance is drastically degraded by a congested situation. We focus our discussion on throttling, injection limitation in other words, as one of the most hopeful solutions to the congestion problem. Our approach is inspired from physics. We define entropy as a desirable metric for representing the network’s congestion level. We also define packet mobility ratio as a proper approximation of entropy. Thus we reach a new throttling method called ‘Entropy Throttling’ that is based on theoretical discussion on congestion. Evaluation results by our simulator reveal effectiveness of the proposed method.
