基于DSCP值的多SSID流分类设计

摘要

很多家用路由器都带有QoS（服务质量）功能，且能虚拟出多个SSID（服务集标识）。这篇文章主要介绍了一种区分多SSID的流分类方法，利用IP头部的DSCP值，为每一个SSID数据流做上标记，使得路由器能够区分连接在不同SSID上的业务，从而实现路由器的QoS功能。最后，对流分类的设计效果进行了实验验证。%Many home router have QoS(Quality of Service)function ,and has multiple SSID(Service Set Identifier).The article mainly introduce a flow classification method that can classify multiple SSID .It used DSCP value in IP head to mark each SSID data stream. So that the router can distinguish different business attached to SSID, so can realize the router QoS function . Finally, it used the experiment to test and verify the design effect of flow classification.
