Great video! Hovewer, I didn't quite get why was there a need for a Policer at 9:10. Wouldn't a Shaper be enough to achieve this kind of configuration? It will automatically limit the rate of the packages and keep it @ 100 Mbps, so the Policer won't be doing anything with it since the upcoming packages are conforming. Could someone please point out, what am I missing here?
@pizza_t1me shapers are usually applied on egress and policers are applied on ingress. Policers and shapers are basically just terms used as rate limiting techniques. In both cases you've to use CIR, EIR, CBS and EBS. But as mentioned in the video, shapers are not agressive and don't drop the traffic. Understand it this way, applying rate limit at egress (shaping) is not agressive and won't drop traffic but applying rate limit at ingress (policing) is agressive. Now your question, why use policing? cuz that's what ISPs do to limit the traffic as in this example customer only paid for 100mbps link. Hope this helps :)
@@hilalsaeed7932 Thank you for taking the time to answer, you made it alot clearer! My confusion was probably due to me not taking into the accout that customer router is, well, cutomer's and is not guaranteed to transfer data @100Mbs (could be up to 1GBps as this is the maximum the chennel can handle). In order to account for that, policer is necessary on the IPSs side.
Wow man. You should do more videos . I spent hours understanding the topic . You just made it so simple in just 3 videos. . 👍
Thanks! I put a lot of time into trying to weed out the noise, and focus on the important parts. Glad to hear it's working!
Definitely Genius, You should do more videos.. what a great instructor, I have never studied a hard topic as easier as this series
Clear and concise explanation, excellent intro to QoS. Thank you.
Glad it's helpding, thanks!
Awesome! Great tempo, great explanation, and great illustrations. I look forward to bucket concepts.
Thanks!
Buckets get more complicated, but I'll see what I can do...

@@pizza_t1me no issues mate ✌️Glad to know I was able to make it cleat for you 🙂
And yes exactly that’s why policing was applied 🫡
great video.
Thank you!
Thank you !
You're welcome!
