摘要

最近，802.11aa标准发布了新的修订版本。其主要目标是提高对音视频流量流的服务质量支持。其中，它定义了与适当的流量选择程序相结合的访问内类别优先级机制，以便与目前使用的EDCA相比增加流量优先级的粒度。本文对H.264视频流下新特性对体验质量(QoE)可能产生的影响进行了初步研究。得到的结果表明，IEEE 802.11aa和802.1Q参数应该调优，以有效地利用可用带宽。

Impact of the IEEE 802.11aa intra-AC prioritization on QoE for H.264 compression

Recently, a new 802.11aa amendment has been released. Its main goal is to increase quality of service support for audio-video traffic streams. Among others, it defines the intra-access category prioritization mechanism coupled with appropriate traffic selection procedures, in order to increase the granularity of traffic prioritization in comparison to the currently used EDCA. This paper presents the preliminary study of the possible impact of the new feature on quality of experience (QoE) in case of H.264 video streams. The obtained results show that IEEE 802.11aa and 802.1Q parameters should be tuned to efficiently use the available bandwidth.
