7.3.8. Quality of Service (QoS)
M!DGE routers are able to prioritize and shape certain kinds of IP traffic. This is currently limited on
egress, which means that only outgoing traffic can be stipulated. The current QoS solution is using
Stochastic Fairness Queueing (SFQ) classes in combination with Hierarchy Token Bucket (HTB) qdiscs.
Its principle of operation can be summarized as ceiling the max. throughput per link and shaping traffic
by reflecting the specified queue priorities. In general, the lowest priority number of a queue gets most
out of the available bandwidth.
In case of demands for other class or qdisc algorithms please contact our support team in order to
evaluate the best approach for your application.
QoS Administration
The administration page can be used to enable and disable QoS.
QoS Classification
The classification section can be used to define the WAN interfaces on which QoS should be active.
Interface: The WAN interface on which QoS should be active.
Bandwidth congestion: The bandwidth congestion method. In case of the auto option, the
system will try to apply limits in a best-effort way. However, it is sug-
gested to set fixed bandwidth limits as they also offer a way of tuning
the QoS behaviour.
