Answer to Question #278802 in Computer Networks for Sandeep

Question

Assume that nodes A and B use a sliding window protocol with 3-bits allocated for frame sequence numbering. Go-back-N protocol is used with a maximum transmission window size of 8 frames. A sends frames to B and it so happens that in one instance, A sends B a full window of frames numbered 0-7. B sends back an acknowledgement frame of RR0. Which frame does A send to B then?

Answer 1

RR0 indicates that frame 0 was successfully received, so then nodes A send frame 1 to node B
