 + 
 +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% \\
