Go back N protocol | Data Communication | Lec-17 | Bhanu Priya

[@videowatcher4852]

WARNING: the receiver does not send a negative ACK, instead, the sender has a re-transmission timeout (RTO), in which if that time is elapsed, it re-transmits the lost packages.

I appreciate when Indians explain lectures related to computer in English, because you guys really the KINGS OF COMPUTER SCIENCE ! this video really helps me in understanding go back n. Thank you.

[@sumitburman6385]

Not only in computer science dear, being an old age culture we had been master in many subjects. Be it spirituality, medical science, etc. Do Come India once and experience diversities here.

[@pk3059]

LOL "KINGS OF COMPUTER SCIENCE" where did that come from?

[@Waytoearnguy]

But not did competition with Pakistan🥰🥰🥰🤞

[@inam98]

Great Lecture👍. One correction: Sender window size is not equal to 1 ,it is equal to N.

[@sunnyrockzz143]

She said if N=1

[@sukruthams6041]

Only SR Protocol uses NAK.. In Go-back N after expiration of timeout timer, the frame is resent back

[@payelbanerjee9192]

like in stop and wait, where the timer is set for each frame on sender side and unless an ACK for a frame is reached by that time, no more frames are sent . What happens here, I mean after how much time the sender checks for acknowledgements of the frames ? Say frame 1, 2, 3 has been sent as in go back N cumulative ack is there , so will the sender expects the ack after sending all the frames or it goes on checking the acknowledgements while sending frames ? Say,frame 2 is lost , so receiver does not send acknowledgement for frame 2 so will sender stop sending frames and send frame 2 or it will send all the frames and then only sits for checking acknowledgments and by not getting ack of frame 2 , starts retransmitting all from frame 2 ?

Ma'am what is difference btw one bit sliding window protocol and sliding window protocol

[@harshtharyani6979]

size of sender window is 0 to 2^n - 1 and receiver window always one ????????????? in go and back protocols

[@muskangupta4152]

Yes

[@pabbisettysriranga1255]

There is no such concept of negative acknowlegement in go back-N. It is there only in selective repeat
