====== QoS Quality of Service ======

The ratio must not exceed 40:1 \\
If there is only traffic for one queue it may use the unused bandwidth of the other queues\\
Only the output can be configured. \\

**Bandwith: fixed (WWANX/WAN/OpenVPN) ** \\
{{:configuration:qos_fixed.png?1200|}}
example: \\
high: TOS (Dec) 184 = DSCP (Dec), 46 (Hex) 0x2E / for voice application\\
low:  TOS (Dec) 104 = DSCP (Dec), 26 (Hex) 0x1A / for video application\\
default: All OTHER = not specified

ratio: 19:6:1 = 26Mbit/s bandwidth. This is also the interface output limit. \\ 
Because of this it is important to know the permanent throughput . \\
QoS is no longer working if the throughput falls under 26Mbit/s  .\\

**Bandwidth: auto(WWANX)  ** \\
IP to ping: Configure a reachable host in the internet, preferably the target host. \\
Based on the RTT the bandwith ratio is divided as follows: \\
higest priority = 50%, \\ 
middle priority = 45%, \\
lowest priority = 5% \\
