Abstract(in English) This paper proposes QoS control, based on DiffServ architecture, in Multi-layer Networks which support simultaneously both a IP hop-by-hop transmission and a cut-through transmission using end-to-end lambda paths. Four QoS control types, which categorized based on a class differentiation type (using DifFServ queue or using class-based lambda) and a transmission type (IP hop-by-hop transmission or lambda path cut-through transmission) are shown. Then, the four QoS control types are evaluated using simulation. The results show the increasing rate of network cost for lambda path cut-through transmission turns rapidly smaller in large traffic case, while IP hop-by-hop transmission achieves lower cost in small traffic case. Finally, applicability conditions for these QoS control types are clarified from the points of traffic volume and DiffServ queue cost.
