Abstract(in English) This paper proposes a link utilization estimation scheme, based on delay measurement considering a multiple-queue model. A conventional scheme is only applied to a single-queue model. However, nodes in an actual network have multiple queues. In the multiple-queue model, link utilization is not determined because an observer cannot determine packet delay. It is caused by either the queue which is utilized, or a node processor run other packets at another queues. The proposed scheme measures all X_i, the ratio of probe packets waited in each queues. It solves the formula of X_i and U. An evaluation simulation shows thaestimation results are consistent with the theoretical formula.
