[@viraj1228]

i think m itself is an window size and 2^m-1 is a sequence number for frames,correct me if i am wrong

Are we going to send Ack to sender if receiver descard the 0 frame @4:48

[@Luffy_2804]

nice explanation sir : )

[@BulletRrajaji]

What is window here

[@67_rohitraj54]

the number of frames that are sent at once from sender to receiver.

[@humaira1976]

I'm not getting it, isn't there any other way of solving this?

[@mainakghosh7496]

same

[@ramatalwadker]

How does it become cumulative ack when the receiver is sending individual ack?

[@mohammadtanveer8606]

As we are transmitting window size from sender and no frames are lost then the rn is increment by one

[@chitwanverma4536]

sir could you make this video explaining on board . unable to understand.

[@ashishmathur7592]

On second case how cumulative ack will occur when the size of receiver window is 1 as receiver will wait for frame 2 and next expected frame will be 2 then how it send ACK3

[@rabiakainat7865]

As ma wo frames sara bhjha ga phla he PR receiver 1 by one accept kray ga to wo ack ka bagair next accept krka next k ack bhj daga

From which textbook did he take the figures from? Does anybody know?

[@abdulraqeeb7149]

You are too good

[@anjalifarkase7591]

I was really confused after 1:00 , that "... wo jo do hai wo do nahi... do se do... do ke baad ..." really confusing.

[@BROKENPEN.]

In simple agar sender ko 6 packets send Krna hai windows size should be 7 , agar m=2, 2^2 -1 = 3 ( too small) agar m = 3 2 ^3 - 1 = 7 (just ok ) now the value of m should be 3 which is less than 2^m (2^3 = 8) To jab sender sends 1,2,3,4,5,6 (assume name of packets) agar packet 3 lost hogaya to 1,2 is received but 3 is not received to 4,5,6 ko receive nhi le gay uska pahle 3 chahiye to receive phir (NAKN ) beja ga 3 ka to sender will go back to send packet 3,4,5,6 (window size is 7) that is all

[@divyakhot9178]
