We are developing an Optical Layer-2 Switch Network which utilize both WDM and TDM technologies in order to provide energy-saving and flexible metro networks. In this network, bandwidth of each TDM path is dynamically controlled in response to traffic fluctuation. Hence, it is necessary to execute time-slot scheduling of TDM paths as brief a period as possible. Since 10,000 paths reside in our assumed metro network, conventional scheduling method cannot be finished in a short time. We have developed hierarchical scheduling method in order to reduce the calculation time. However, this method is unsuitable for non-uniform or inhomogeneous traffic distribution. In this paper, we propose novel hierarchical scheduling method by taking into consideration the characteristics of optical layer-2 switch network in terms of traffic distribution. And we verify the effectiveness of our proposed method through numerical experiment. |
