Chris, I think this may be the best material I've ever come across for understanding some of the specific elements of TCP. The time you spent on the receive window confirmed the detail I have in my notes, but the congestion window explanation has always been somewhat elusive online! I have some pretty concise notes, but to see the concepts played out visually in a steady way, and also in context with the capture files, was simply great to watch. Didn't feel like an hour and 20mins. Some great tips too when analysing in Wireshark. Great work - this is how TCP should be taught.

Im 40 years old.. just got interested into this stuff and working on my ccna and i wish you were my teacher..thank you for your great videos

[abc-bykb]

Man your way of explaining things is just absolutely amazing! Great video!

[XanderPetty]

These are the best two TCP videos I've seen. Studying for the CCNP ROUTE and chapter one is diving into TCP. This really helped tie things together.

Awesome stuff, both parts. I've worked as an F5 support engineer for a couple years prior to watching this, and I took a ton away from watching these two sessions. Thanks alot man!

[loodack]

This guy does awesome job at explaining!

Hello Chris,
Many thanks for uploading this content.
I'm networking core and I'm surely one of those layer 3 heads. I normally joke about doing stuff at layer 3.5 to my application colleagues. Your presentation changed a bit of my perception on troubleshooting with wireshark.
I see I still having so much to cover on my studies and I appreciate very much your effort to provide such quality material.

Chris, awesome as always. When I started looking deeper into protocol analysis, of course with your help, I started understanding network and other technologies much better, it all started to make so much more sense. Thank you for those sessions, master!
PS please do more, boy do i enjoy those

[sarangad]

Chris, this is like getting enlightened, thank you

[sameerkumar]

Very Well explained case files.. you made me fan of you

[bijayjungkarki]

As a fresher starting as a Support engineer this was amazing session on TCP, hope to see more!

[manigandansrinivasan]

Chris .... You did mindblowing lecture ... Your selfless thought by sharing what you learned are commendable ....

[koneru]

You are the best and no one can beat you... Keep up the good job...

[lenyfreeman]

These two videos took my understanding of TCP to a whole new level. Thank you.

This is an awesome talk I am new to wireshark and packets but watching your talk on D.Bombal right before this talk made the topic understandable and approachable.

[PatrickLangendoen]

Been looking out for the second part for a while. Thank you, sir. This is very informative and brought in a very good way. You rock!
