Abstract: This paper studies an end to end QoS architecture between wireless and wire based on DiffServ and IEEE802.11e, introduces the characters of 802.11e, 802.1D/Q and DiffServ, analyzes priorities mapping each other and presents the hierarchical QoS parameters interface between DiffServ and 802.11e in terms of traffic classifying, markering and shaping.

Key words: WLAN, 802.11e, DiffServ, QoS

摘要: 研究了从无线到有线网的基于IEEE802.11e和DiffServ(区分服务)的端到端的QoS结构,介绍了802.11e、802.1D/Q和DiffServ的特点,并就它们之间的优先级映射进行了分析,从流量分类、标记、整形方面对IEEE802.11e和DiffServ的QoS参数提出了分级的接口。
