Hi.

This actually depends on what sort of prioritizing you want to achieve.
Nowadays you'd better be using MQC rather than legacy PQ (for real-life
scenarios). You will not catch an FTP to non-standard server ports with
PQ for instance.

And even for lab section IMO it is a lack of wording here. What is the
goal? To prioritize while having traffic congestion or in terms of
bandwidth usage (regardless of load)?
