Abstract :
The QoS problem is introduced in this paper firstly, then two models for IP QoS are analyzed, they are integrated services architecture model (IntServ) and differentiated services architecture model (DiffServ) respectively. Based on the analysis, an improved ATN network structure-using IP QoS architecture DiffServ in ATN is proposed. This paper also proposes a new way to manage the queues in order to improve the QoS service, which lies in AF and BE queue manage algorithm in ATN over DiffServ: AF and BE queue share RIO algorithm to manage queue. The simulation results show: the IP QoS has matured enough, so as to provide the QoS service for ATN architecture and the improved algorithm effectively realizes that packets with different priority will achieve different class QoS service in ATN.
