[@kaushikkumar2940]

Sir pls uplode video as soon as possible

[@umairahmed5171]

If the header of the frame allows 3 bits for the sequence number (i.e. m=3) then
what will be the
1) Send window size
2) Receive window size
Please help me to solve this

[@ankitchaudhary6142]

Hello sir, I did the same approach but did not consider empty packets after my 9th packet. So I assumed the whole window of packet 7,8,9 would be retransmitted and hence total 18 packets i.e. option (D).
Although I believe that's definitely incorrect.
Plzz confirm.. plz reply🙏🙏

[@Pruthvikajaykumar]

you have to consider the empty packets after 9th packet. Every time the sender gets acknowledgement from receiver, the window slides.

[@THE_MSL_77]

Sir, is number of acknowledgements sent by station B is 8 ?

[@arjunkhanna1803]

isn't there a cumulative ack?

[@user-lb1fl7sh8m]

Answer : 16

[@likhithraj4239]

9 packet= why dint you considered from 0-9, according to the previous video packet was 11 you have been considered from 0-11

[@_Khushil]

Btw op explanation

[@AnimeWorld39008]

what is the short cut?

[@ishankhandelwal2519]

Wow

[@kl191]

Station YEE needs to send a message..

[@iftekharfahimaziz4369]

Shouldn't we consider total frame size from (0-8) instead of 1 to 9 as in previous video?

[@ADITISAMARGADE]

yeah we can

[@Prabhatkumar-vq5cm]

what if window goes ahead of the defaulted frame , will be send back frames from starting of window or we will go back to the defaulted window?

[@Prabhatkumar-vq5cm]

Well i am not sure if that kind of situation ever arise.

Go back n is a flow control mechanisms. Iam I right sir

[@taky1835]

I have got option c)16
2:25

[@abhimalyachowdhury7835]

some trick should be explained so that it can be solved under a minute....Basically if the no. of packets to be transmitted is 20 or 25 instead of 9

[@HimaSankar-ki1ub]

It have to discard 3 frame also ,as 2,3,,4,5 are retransmited ,why only 4 ,5 is discarded ,3 also should be discarded

[@krishma1680]

Yep I discarded 3,4 and my final answer is 18 😢

[@errorless7921]

​@@krishma1680hn Bhai mera vi

[@anjankheto1177]

Window size is 3 then why 7 is sent along with 456

[@physicsdepartment6579]

what is GATE CS

[@SLAnimalLovers98718]

Wow... so beautifully explained 👏
Thanks 😇
