Abstract(in English) In recent years elephant flows are increasing by expansion of P2P applications in the Internet. As a result, bandwidth is taken by the particular user and unfairness in resources allocation occurs. Main packet scheduling mechanism currently employed is FIFO where the available bandwidth of mice flows is limited by elephant flows. LAS (Least Attained Service) which decides transfer priority of packets by total amount of transfered data of each flow was proposed to solve this problem. However, routers with LAS must manage information of all flows to determine priorities by total amount of transfered data, so there is the issue of router load increase. This paper proposes the packet scheduling which improves LAS to reduce the load of routers by using two or more queues. The proposed method can transfer mice flows in advance and reduce the load of routers. Moreover, its fair performance is shown through simulation.
