| + | 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% \\ | ||
