I really enjoy your deep dives, just bumped into your classes few days ago and I'm taken. QOS is one of my worst nightmares, I found it very hard to understand till now, sooo many thanks for this!

[negushak]

thank you Mr Wallace i used to skip that part loool i took time for that, watching it twice ... thank's again (from France)

[Dimaximus-K]

This man is simply amazing!! honestly the best and most interesting lectures i'v ever listened to!

[majiddehbi]

Hello Mr. Wallace after some English courses I can tell you now that I'm enjoying listening to you even tonnes of hours

[farhatullah]

Great explanation. I have good experience on the QoS offload to high speed SmartNIC/DPU

[clongdiver]

OMG! I am so glad that found your channel!! Great video! watched the whole thing and took notes! Gonna check out some more of what you have on QoS as I have been teaching myself while configuring EMC Powerswitch 5232F-ON for our HCI RoCE 100GbE deployment. Great stuff, thanks for doing this!

[kosmonautofficial]

Awesome thank you so much this clears up a lot! Getting ready for encor v1.1

[cedrickmukinayi]

Kevin ! Kevin ! you are just amazing. QoS has always been a nightmare for me; boom you have demystified it

[CAMPUSTOP]

Good Video, Thanks Kevin. I would also appreciate more practices.

At 1:14:40
Dual-Bucket Dual-Rate:
It is not clear what does it mean, when you say, we are not able to send traffic from the CIR bucket?
Why would be not able to send the traffic once the bucket is full, when we can send it from the PIR bucket?

Many thanks in advance for everything, I love your classes and I still come back to them to refresh my understanding once in a while, Ironically I always find a word or two that you mentioned and I messed!

A FAN FOR MANY YEARS!!

[mehul]

Best video, everything under one roof. 👌🏻
SUBSCRIBED.. ❤
Can you suggest some books to dive deep into the topics of WLan networking and computer networking, your videos + books together will help a lot...

[doantube]

Awsome lesson on QoS. Thanks, Kevin!

[refaiabdeen]

Cheers Mate. That was a Awesome Intro to QOS. Cheers

[tonyhoy]

Great course. Well worth the time. Thanks Kev!

[sheoranv]

This is probably the wrong place to put this but who agrees the next deep dive topic should be on multicast?

[alejandrocoello]

Thank you so much, that was a great course

[onkarghaisasmusic]

Great course. I still have one doubt. If I have understood correctly, ingress and egress qos policies will be applied on access ports where endpoints will connect. what about uplink port of the switch? will any QoS policy apply on that port?

[luigivalenza]

Love your videos.
I thought policing was best for UDP traffic and shaping for TCP traffic. Is my statement still the case?

[anjumbukhari]

There is a mistake at 38:00 Kevin says that the min threshold for high drop probability but it should be min threshold for low drop mistake repeated at 50:01 where he says not exceeded the min drop threshold for medium and high, it should be not exceeded the min drop threshold for medium and low...

[Ramel]

The ECN bits don't make sense to me. Why would the ECN capable bit ever be set to 0 (off) if it's ECN capable? If bits 7 and 8 are set to 01 or 10 that means the router is ECN capable, but why would it be 01 in the first place?
