Man this networks class makes me want to move into a van down by the river. I can't wait for this semester to end. Thank you for the content to help me get through.
I sat for half an hour listening to my professor 😹😹 i didn't understand accept the heading..but when u detailed the concept by showing the animation within a fraction of second I was able to understand thanks a lot
Nice. Indian letures are the best. I'm not used to with Indian English but there is sub available so I was still able to understand. Thanks for knowledgements!
It may be important to add, that if ACK 2 is lost but the sender still recieves ACK 3, he knows that the receiver actually recieved PCKT 2 even if he didnt receive the acknowledgement for it. So he will not resend PCKT 2.
that's would be right if it's explicitly mentioned that we are using " Including acknowledgement " : which means we acknowledge all previous frames the sender has received and not every frame individually. For example, if ACK n is received by the sender, it means that all frames ( from 0 to n-1 ) are marked as received. Even though it's not the case by one of the frame ( frame get lost ).
I guess, As soon as the time's out(in waiting for acknowledgement of Frame2), the next frames i.e., Frame3,4,5 which were already sent are discarded ..So, the receiver will not receive any frames and thereby it can't acknowledge.
one of the best explainations one can get get on youtube....please let me know if you guyz have a proper course,...i would love to do it...ineed certification and project...
Great short lesson, you were very clear and easy to understand. However, I'd like to point out that in the example you provided there's an error: GbN uses cumulative ACKs, meaning if ACK (packet 2) is never received, but ACK3 is received, we assume that ACK2 was lost but the packet itself was received.
Thanks for the video. You should also include timers like start timer, restart and stop timers according to packets sent/Recived or lost, the timer concept i also important to understand.
Omg,,, I clearly understood this. I was looking for some tutorials before my exam and I m lucky enough to find this channel. Thank you so much. Explanation is crystal clear. 🤗❤️
We can find all the topics online but you will find the well organized playlist very rare.. Till Now I have completed from 1st video to this 61st video.. I hope I can complete this as soon as possible..

11 minutes of your video explaining is better than my professor full 4 hours lecture session. Bad lecturers will tell you to self learn despite the expensive tuition fees we paid them. Well, by using self learning as an excuse, this caused more and more professors degrade in their teaching. Sounds good huh?
Towards the end, you mention that the receiver did not get frame 2. That is not consistent with the timing diagram. Frame 2 is actually received, it is the ACK for frame 2 that is lost, so when the sender times out, it sends 2,3,4,5 and because the receiver in Go Back N can only receive in-order frames, that is why the initial transmissions for frames 4 and 5 are discarded.
as you said that the frame 4 and 5 are discarded by the receiver because the frame 2 was lost, after this frame 2, the frame 3 was also sent, what about that ? is that also be discarded by the receiver ?
at 5:10; what ll b sequence number if we have the window size n=3,, which can not be represented in power of 2?? In this case what should be added or subtracted for the sequence number.
Whenever there is a terror of exams, Neso Academy is standing by us as a savior. Thanks A Lot Neso Team

Is frame 3 also discarded? I think he missed that
@@nomen385 Yes, anything out of order is discarded.
@@nomen385 yes i also felt the same thanks !!

Thank you so much sir 🙏
Nice explanation bro. Please write and explain program also bro..
Nice explanation😊 Thanku so much
Tqsm.. For making these useful videos🙂😇
Super mowaa super ga cheppav
1000% correct way....
i think the receiver will also discard the 2and 3 because they are already there as the ACK is lost but the receiver had that frame 2 and 3
if i took a shot every time this man said GO - BACK - N ARQ i'd be on the floor dead
as you said that the frame 4 and 5 are discarded by the receiver because the frame 2 was lost, after this frame 2, the frame 3 was also sent, what about that ? is that also be discarded by the receiver ?
Superb video 🌟
Life saver
Very helpful. Thank you so much
You are awesome💘
Having exam today afternoon 😂😂
Same after 1 hr
Same after 25 minutes
thanks
Thank you so much 💓 💗 💛 💖 😊
Thanks a lot.
Thank you so much tomorrow is my exm 🥺
#thank_you_NesoAcademy
ideally it should discard frame 3,4,5 for our example if 2 is lost and not received by the sender.
have exam at 2pm
watching this at 1pm 🎉
Legend
what about the frame 3, is it discard or not. Because frame 3 still in the window as well as sender side. So, only 4,5 are discarded or 3,4,5.
same doubt 🥲
Having exam tomorrow
at 5:10; what ll b sequence number if we have the window size n=3,, which can not be represented in power of 2?? In this case what should be added or subtracted for the sequence number.
Thnku sir
Tq so much man
If I correct then 3 4 5 are discarded by receiver instead of 4 and 5.
Good explanation
Amazing ❤
Awesome .. Thankssss
THANKS TEACHER
