In this video, Jeremy Cioara covers the Quality of Service (QoS) tools at your disposal in network environments. Many of these mechanisms perform similar functions but use different methods. Understanding the effect each tool is designed to have will allow you to know when to leverage the most appropriate approach in a given situation.
QoS tools often have the same goals but approach a situation in various ways. This begins with classification, identifying different traffic types so a sysadmin can properly prioritize them. Marking is an optional phase of QoS, but can be an incredibly useful systematic approach that simplifies long-term network maintenance. Policing throttles down traffic, which is most often applied when you need to limit or eliminate peer-to-peer sharing. This is the only “anti-QoS” tool in our inventory. Shaping, on the other hand, is a much friendlier approach directed at traffic that needs to be managed instead of mitigated. Congestion avoidance is an efficient way to manage potential bandwidth overload. Arguably the most powerful QoS tool is queueing, which prioritizes packets based on predetermined protocols.

He is the best instructor on CBTNuggets
You did teach me everything i need in network 7 years ago. You r perfect. Thanks sir.
All videos from Jeremy are so simple and clear to understand. I just love watching his videos
Would love to see a proper QoS/CoS series covering Service Provider to customer QoS implementations. Taking each of the tools mentioned in this MicroNugget and mapping to real world use cases
My Guy, Jeremy...one of the best Teachers. I love his videos....so short and on point!!!
Hi Jeremy, I want sincerely thank you today. You are the one who helped me understand networking basics. And from your training videos I am working with CCIEs and experts today. Keep the good educating. Love you brother.
Keith And jeremy are both the gods of cisco !!!!!!!
Keith's voice animation makes all these micronuggets so very catchy and easy to understand! Way to go Keith!
This is not Keith but Jeremy to my opinion
whoa, thank you. It didn't require me prerequisite IT knowledge to understand this video.
videos from Jeremy are simple and easy to understand
Well done guys. This is one of the cleanest and straight forward explanations of QoS that I have seen. Keep the good work.
That sounds like a great idea for a MicroNugget. Request this MicroNugget at the link found in the description above.
Nice and short, great video. Thanks for sharing.
Best QOS summary ever
All videos from Jeremy are amazing!
Thank you for sharing. I have an Electrical Eng final exam next week and the video helps understand networking techniques. :-D
NBAR how it pratically works (inspection based on which layers/identifiers), how does the switch build up application data table and how does it share this with other tools that can benefit QoS analytics? How does it work together with Netflow? I obvously struggle to understand NBAR and do not have the time to read a 200 page book about it. ;-)
Awesome Jeremy ..... your videos are always very helpful ....
Well explained in a very simple way.thanks
This fellow is champion!
Hi Jeremy..It would be great if you can create a micro nugget with a live example of how packets are getting classified in an ACL,how it is policed , how it is wrandom detected and finally how it is shaped...Would like to follow a packets right from classification till it leaves the interface using shaping...Thank you.
A very nice and easy to understand video .. thanks!
great video !!
easy to understand...excellent!!!
Jeremy-do you have a course dedicated to QoS, or can you recommend the best pieces to learn in on the CBT Nuggets site? In one of the voice, (I think), nuggets it sounds like you mention a dedicated course. Thanks
Could you possibly make a micro nugget about the real infrastructure of the internet, the details about what happens when packets leave our home networks? Thanks.
How can i calculate CBS (committed burst size) for FE interface according to CAR (committed access rate) Methodology and the token bucket Logarithm.
Note: The CIR (committed information rate) for FE interface is 1024 kbps.
Like to see a video on LLQ/CBWFQ
Thanks for the video =)
Oh right, done!
what is difference between RED & WRED
My 4G modem has DSCP in Loadbalance
Packet shooting snipers needs an RFC.
