Hi, all

I am interested in Linux related QoS, especially PRIO queue discipline (qdisc).

First question:
The TCP stream with higher priority than UDP stream with lower priority
experienced starvation in stead of UDP stream. Is it correct?
...

All correct: man tc-prio:

"BUGS
Large amounts of traffic in the lower bands can cause starvation of higher bands. Can be prevented by attaching a shaper (for example, tc-tbf(8) to these bands to make sure they cannot dominate the link."
