11.20.1 Software QoS – Preface
The Ralink SoC SW QoS supports many different types of classification, rate limitation, and
DSCP remarking. Ralink SoC SW QoS is based on the Linux Qdiscs, TC, and iptables. Ralink SoC
SW QoS supports download and upload stream on a WAN interface.
11.20.2 Software QoS – Concept
The Ralink SoC SW QoS architecture is shown in the subsequent figure. The Classifier module
classifies incoming packets into the Shaper module. The Shaper module has 4 queues (groups)
to do rate limitation, and then the Remark module rewrites the DSCP field of the packet if it is
necessary.
