With the development of next generation network (NGN), reasonable service quality evaluation is essential in network management. Based on NGN service characteristics, this article presents a comprehensive service quality evaluation system from two perspectives: quantitative and qualitative. From the quantitative point of view, this article brings forward the normalized service level achievement function...
IEEE 802.11e is put forward to improve the quality of service (QoS) of WLAN. But how to apply it to different applications is still a problem. This paper focus on apply EDCA to improve the QoS of MPEG4 service over WLAN. The scheme use cross-layer design to map different type of MPEG4 frames to different EDCA AC in order to get better QoS and also proposed an IAEDCF to further improve the QoS. From...
