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...
In this paper, we propose video quality control system (VQCS) which tan control video service quality through the monitoring of end-to-end available bandwidth for video streaming service like IPTV in NGN convergence network. Various multimedia services such as video, voice and gaming service can be provided by IPTV, and these services require large amounts of bandwidth. At this time, video quality...
In this paper, we propose a method to enhance service user's experience quality when various multimedia services is provided in converged network environment. With the growth of service experience quality interest, multimedia service providers need a method to control experience quality when experience quality is not satisfied by service users. In order to enhance user's experience quality, we design...
In this paper, we propose a network performance monitoring method which can measure delay of each network using the RTCP(Real-time Transport Control Protocol) timestamp fields to detect a trouble section in interworking environment. According to the increment of real-time multimedia service provision, network performance monitoring method is necessarily needed for QoS management of real-time services...
Currently, the satisfaction of user is becoming one of the most important topics concerned by the service providers. So we propose the approach method for the objective QoE measurement through the QoS parameters. The measurements and provisioning of the quality of service (QoS) are generally defined in terms of network delivery capacity and resource availability, not in terms of satisfaction to the...
