| Abstract(in English) | Traffic engineering (TE) is one efficient way of accommodating traffic that changes unpredictably. The traffic information of the whole network is essential to reconfigure the routes of the whole network. However, it is difficult to collect the traffic information of the whole network in a short period of time. Thus, the reconfiguration of the routes of the whole network cannot be performed in a short period of time. In this paper, we develop a method that can handle the traffic changes in a short time in a large-scale network. In our method, we hierarchically divide the network into several ranges. Our method reconfigures the routes within small ranges in a short period of time to handle the traffic changes that occur in a short period of time. In addition, we also reconfigure the routes of the whole network to handle the significant traffic change that cannot be handled by the reconfiguration within small ranges. In this paper we evaluate our method by simulation and clarify that our method achieves the similar maximum link utilization to the method using traffic information of the whole network. |
