| Abstract(in English) | In network performance measurement in overlay networks, measurement conflict occurs when multiple overlay paths share the underlay network route when they are measured at the same time, which increase the network load and the measurement accuracy degrades. We have proposed the spatial composition method of measurement results, where we estimate the network performance of the longer overlay path from the measurement results of partial paths, when the longer path includes other overlay nodes. In this report, we evaluate the accuracy of the composition method in terms of delay, packet loss ratio, and TCP throughput, by utilizing the measurement results in PlanetLab environment. From the evaluation results, we confirm that the estimation error is enough small for all metrics, but sometimes the error becomes large especially when the load of the internal overlay node is high. |
