From any given AF value, to have the decimal value, multiply the IP precedence *8 then, Drop Probabilty *2. Then Add both of them. ie AF43 = (4*8) + (3*2) = 32+6 = 38:)

You are an absolutely phenomenal teacher! I love the mix of metaphors, practical applications, and theory you use to teach a concept... the combo of all three really makes the concepts stick in the mind. Keep up the great work!
-
Best explanation I’ve watched by now. Thanks Kevin.
-
Amazing video Kevin. When I was in my college cisco classes, we briefly skimmed over QoS, and I'll admit that it absolutely bored me out of my mind. This had my full attention throughout the entire video, and I can't believe how easy you made it with your explanations and examples. Thank you so much!

Kevin, thanks. Now I know how to manage QoS. It is closely similar to CPU scheduling. Thank you so much. Now I can save the bandwidth of my client's network congestion.

Thanks Kevin, always educational and professional listening.

Fantastic video - really well explained with examples and at a good pace to follow along to. Coming into this with no knowledge of QoS - it has really helped to make me understand the concepts. Thank you!

In networking, the airport analogy is what I always use for anything. QoS, Security, Routing, even packet size! :)
