| Abstract(in English) | Multilayer traffic engineering(TE) is one efficient way for accommodating traffic that fluctuates unpredictably, which optimizes resource usage by dynamically reconfiguring the VNT(virtual network topology). However, the traffic matrices, which are required by the existing multilayer TE, are hard to monitor directly. Though several methods to estimate traffic matrices are proposed, the estimated traffic matrices include estimation errors. In this paper, we introduce a method which can efficiently reconfigure the VNT without the impact of estimation errors even when we cannot monitor traffic matrices directly. In this method, we reconfigure the VNT considering all possible traffic matrices based on the monitored link loads. Moreover, we propose a method which select and monitor a small number of end-to-end traffic to add the efficient measurement for the VNT reconfiguration. In this paper, we evaluate our method by simulation to show that our method can select and monitor end-to-end traffic effectively to reconfigure the VNT without high link utilizations. |
