In this paper, we propose QoS-aware AQM(Active Queue Management) method considering video quality level that service users request in DiffServ network environment. QoS provision is essential in order to provide multimedia services because real-time multimedia services such as IPTV and VoIP are sensitive to delay and packet loss. However, existing AQM methods can't guarantee QoS for a multimedia service because they control queue threshold just considering queueing delay or accept the service considering only packet loss rate. So, we propose the QoS-aware AQM method guaranteeing end-to-end network delay and packet loss rate which can derive the QoS lever range for multimedia service requested in each hop according to the number of hops in IPTV CDN(Contents Delivery Network). As another contribution of the proposed scheme, its compatibility in DiffServ is also considered by cooperating with the provider's quality policy.
