| Abstract(in English) | We consider multilayer traffic engineering (TE) strategies in IP and Optical networks. TE approach require a traffic matrix to compute the optimal topology, but it is infeasible to collect traffic matrix information for large-scale networks due the N-square problem. Hence we evaluate the impact of the traffic matrix estimation on multilayer TE. The results shows that even in the case of using the estimated traffic matrix, multilayer TE can improve the amount of traffic the network can accomodate, though the impact of estimation errors is not small. We also propose a new method to reduce the error of estimation errors by reestimating a part of traffic matrix. We evaluate the proposed method by simulation. The results shows that to reduce the impact of estimation errors on TE, we need to select the entries of traffic matrix to reestimate by considering the balance between total of underestimate and overestimate errors. |
