| Abstract: | The performances of the input-buffered switch fabrics are analyzed by means of the proba- bility generation function method. A simple neural network arbitration algorithm based on delay is proposed in order to schedule the head of line of the switch. The algorithm is fast and very easy to im- plement. The simulation results show that the performances are improved. Therefore, the method is effective and realistic. |
