Consider two hosts A and B that are quite far apart, i.e., dpg >> dtx. They are communicating using the Go-Back-N protocol with a window size of 10 and a sequence number space of 4 bits. Assuming this is a one-way data flow and A is the source of the data and B is the sink, and packets may be lost or corrupted but without reordering. At present, the receive window at B is at [11]. Consider the following (independent) events. i. B receives an uncorrupted data packet with sequence number 13. What will B do? Given this scenario, estimate what are the possible sender windows at A at this moment? Clearly explain your answer. ii. B receives an uncorrupted data packet with sequence number 4. What will B do? Given this scenario, estimate what are the possible sender windows at A at this moment? Clearly explain your answer.
