Special Section on Multimedia QoS Evaluation and Management Technologies

With advances in IP and multimedia technologies, various multimedia services such as video streaming, videophones, and videoconferencing services are being developed and provided. Properly evaluating and managing users’ perceptions of multimedia quality of service (QoS) to provide comfortable multimedia services is important because their performances are not generally guaranteed in present IP networks. Moreover, in the next generation IP network, commercial multimedia services must assure an acceptable QoS. Properly designing or controlling the multimedia application or network is also important.
