TCP Congestion Control

In this video, I describe congestion control in TCP using an illustrative example. The video discusses the additive increase multiplicative decrease aspect of TCP. I also talk about the slow start and the congestion avoidance phases of TCP.

If you want to obtain a certification and a Computer Networks Foundations badge from the State University of New York Binghamton based on the videos in this channel, please visit the link. For obtaining the certification, you will need to pass a multiple choice final exam based on these videos. The course also contains self-assessment quizzes to help you prepare for the finals and for obtaining the certificate.

Saw the video once and already it's in my memory...great explanation..

[trentbell]

I've watched like 4 videos on this and read so many articles, this is the first one that makes sense

[WitchRobinHunter]

Thank a lot, it really helped me to figure out the most difficult part of my course in such a simple way, you're the boss

[chai]

I'm watching this on the day of exam hahaah thank you so much I don't need to study from a book now.

[yzhang]

I'm surprised you don't get more comments but, your videos explaining computer networks are amazing and informative. Thank you very much for sharing your knowledge : )

[jamesd]

You're a beauty man!! You explained it so cleanly

[dangatonegro]

Those slides belong to Professor Kurose, right? I can't find where you are quoting him.

[sanketnawale]

thank you anand I had an oral for the subjrect of sattelite and i was preparing i saw your video which was very hrelfull thanks a lot fir easy explanation

[kumudinigandhesiri]

It’s really helpful I suggest you to make more videos sir!

One point to add is that in TCP reno, if a duplicate acks is received; the cwnd cuts to half which is TCP's Reno threshold(SSH) after loss due to 3 duplicate acks.

[saikalyantarun]

What all cases does the threshold(ssthresh) increase here?

[anantchoudhari]

Hey thanks for the great explanation. One question: How do we decide the initial Slow Start Threshold at 8?

[chanezsfaihi]

Why the Ack of the seg 2 is 4 ansvthen 8 I cant get it please

[nipunc]

At later slides its being explained that the window size is increased exponentially ( to twice) when "each and every ack of previous sent segments has been received" while in previous slides it was told that when the first ack of the 2 segments arrives, the MSS is increased to twice. Please can you explain the same. In general cwnd is max number of segments that are sent before the sender waits for the acknowledgments - that is fine. The question that remains is that does the sender doubles the cwnd when the first ack has come or all the acks for all the previous segments have arrived?

[karthik]

Very precise and clear explaination, thanks for making the video

[himanshubarak]

Very well explained. Thanks for making this video.

[izharkazmi]

Very well explained. It helped a lot. Subscribed the channel also to support the good cause.

[abinayas]

I have one doubt this question and open loop and closed loop congestion control techniques are same ahh

[AdheekRGowda]

your explanation is good but your accent makes it worst
