For which explanation?
And you mean if receiver receives a frame with sequence no. K successfully then will it send an acknowledgement with sequence no. (K+1) or not?
Actually it's implementation dependent. In some places that is the case. The receiver indicates that it has successfully received all the frames upto seq no. K and is wanting frame no. (K+1) now.
And in some places ack might have sequence no. K indicating that receiver has successfully received till frame K.

Hi thanks for you explanation. I have some doubt on following,
Can you please explain......for Go-Back N protocol or other sliding window protocol also (i.e Stop-Wait, ARQ) at a particular time 't', the frame sequence number in sender if 'K', then acknowledgement sequence number from receiver to sender should be k+1. Is this correct if not please explain.
