- Answering the question: "How does the TCP transport protocol work?" Includes discussion of congestion-control, including TCP-Tahoe, TCP-Reno, TCP-NewReno, TCP-CUBIC, TCP-Vegas, and Google BBR.
Based on Computer Networking: A Top-Down Approach 8th edition, Chapter 3, Section 7.

my prof needs an hour for this and doesnt get to the point, thank you for saving me so much time
Wow, he just summarized everything you need to know about TCP congestion control in just 12 minutes. Excellent video
Thanks, glad you enjoyed it!
So glad that TH-cam randomly recommended this video to me. You work is excellent and helpful
Justin, what an incredible explanation. Thank you so much.
I was tired of researching and reading so many books and articles that confused me.
You brilliant and concisely put it all together.
:)
Glad it was helpful!
I agree 200%!
Wow! I was not able to understand Kurose and Ross textbook but this video made it very clear, Thank you sir!
This is a great video. Please make some more!
Thank you! Will do!
Around 1:10 you say that only timeouts were used to indicate congestion in Tahoe, could you provide a source for this? According to Computer Networking-A Top-Down Approach (page 300), Tahoe did use triple ACKs as a congestion indication, but handled it in the same way as congestion indicated by timeouts.
Does Tahoe used fast re transmit for 3 duplicate ACKs ?
I also had thought that "slow start" is a wrong name, but then I thought that maybe the "slow" does not mean the window's increment rate is slow, but the sending speed is slow because the number of packets that can be sent is small (= small window size).
I love you, thank you soooooooooo much
Glad it helped!
so which is better, ctcp or cubic when gaming?
Thank you sir
You are welcome!
i though additive increase, will increase the congestion window after packets equal to prev congestion window is sent and acke
The exact implementation may vary by operating system, but the CWND will increase by 1 MSS by the time each full CWND of data has been acknowledged.
excellet video
Thank you very much!
This is the most complex episode from the series so far.
Yes, the TCP algorithms are complex, but just wait until you get to routing protocols!
Waste of time
