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.

[@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

[@shreyasshenoyt8776]

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

[@anandseetharam]

Thank you

[@trentbell4999]

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

[@chai166]

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

[@anandseetharam]

Good luck with your exam

[@SearchOPal]

Simple and straightforward! thanks

[@yzhang3458]

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 : )

[@anandseetharam]

You are welcome

[@CSERISHINANDHA]

It's because he's trying to use accents which is hard to understand, just use a neutral accent then more people will listen to you speaker.

[@sanketnawale3546]

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

[@abdullahmohammad5613]

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.

[@jamesdouitsis8180]

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

[@karthik0999]

Very precise and clear explaination, thanks for making the video

[@AlokTP]

Very good explanation.

[@dangatonegro]

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

[@kumudinigandhesiri7149]

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

[@nipunc6880]

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?

[@aashishprateek5030]

this is a perfect explanation!

[@t_balle1620]

amazingly explained, thank you!

[@anandseetharam]

Glad it was helpful!

Very well explained!

[@anandseetharam]

Thank you

[@MrMarkgyuro]

subscribed, you explain really well!

[@anandseetharam]

Thanks

[@saikalyantarun1739]

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

[@anantchoudhari2898]

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

[@anandseetharam]

Thanks! That is used here for explanation purposes.

[@anantchoudhari2898]

@@anandseetharam I meant to ask how is it decided in general(the initial ssthresh value). Also, is it a parameter where I can check from the OS?Like going /proc/sys/net/ipv4.

[@henryhailcee9923]

very well explained thank you

[@anandseetharam]

Glad it was helpful!

[@izharkazmi]

So good!

Thank you

[@chanezsfaihi9174]

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

[@mrchow3177]

Brilliant

[@anandseetharam]

Thank you

[@arvindg553]

Best on youtube 💯

[@anandseetharam]

Thank you

[@AhamedKabeer-wn1jb]

GOOD EXPLANTION

[@anandseetharam]

Thanks!

[@abinayas6221]

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

[@nevilholmes5900]

Tcp rano min 6.30

[@bensmith6512]

is this slide stolen from my uni XD

[@anandseetharam]

These slides are from Kurose and Ross (made publicly available with their textbook).

[@rajolihemanthkumar6635]

Slang👎

[@user-mq8os3db2p]

your explanation is good but your accent makes it worst
