At the WTD section in univercd, it says,
"In this example, CoS values 6 and 7 have a greater
importance than the other CoS values, and they are
assigned to the 100-percent drop threshold"
Shouldn't it say something like "because the 2
cos values designate packets with higher delay
tolerence, they are assigned to 100-percent drop
threshold"
The packets assigned to lower drop threshold may
designate packets very important too. How can
they say what they said like that ?
We know what we are doing, we are not just making
queues so that we have jobs to maintain the code
of queuing. The purpose of WTD should be to give
less delay-tolerating packets the proper treatment.
If the packet is important, it shouldn't be assigned
to the queue that is likely congested to those
threshold marks in the first place. We don't send
them to these highly queued queues then decide which
one stays.
