My questions are
What exactly is QoS ?
How does It work ?
Does It work on any network or like the RIP service It needs to be enabled on router/server side too ? / Is it client side ?
I have a D-Link 2730U ADSL modem , It has Enable DSCP/TC Mark & Enable 802.1P Mark & Scheduling Strategy (SP , WRR , CAR) what are all these ?
Whats values "Precedence" (also known as priority) can have ?
Is there any free PDF explaining about this ? (free because I can't buy anything on the internet due to restrictions -- I live in Iran)
I really hope this would also help others .
