一种新的WLAN QOS流量调度算法

An Approach of IP QOS Over WLAN

随着WLAN的迅速发展,越来越多的移动终端用户通过WLAN接入Internet。该文研究背景是把WLAN作为接入手段有效覆盖热点区域,接入IP核心网,在IP层引入IntServ,考虑并讨论在WLAN的更低的层次上支持该技术。鉴于RSVP是IntServ的最主要的信令协议,该文重点将WLAN QOS的消息和参数与RSVP的进行了讨论和比较,并提出了相互映射关系,以解决统一的IP QOS支持。

With the development of WLAN technology, more and more user access internet by WLAN. In this paper, we con sider that WLAN serve as access system to IP core network, efficiently covering hot-spots areas, use IntServ in the IP layer, and discuss how this can be supported by the lower layers of the WLAN. Because RSVP is considered the dominant signaling proto col of IntServ, our discussion focuses on the adoption of RSVP messages and parameters by WLAN QOS mechanisms for the unified QoS supported.
