(300 words) Consider the TCP multiple acknowledgement scheme. A base station (BS) may receive an out of sequence packet that was buffered at an earlier point in time. How can such a situation arise in the network? (3 marks) Actions taken by the BS will depend upon the sequence number of the received packet from the sender (in the wired segment) and sequence number of the last unacknowledged packet (at the BS). Based on these sequence number values, explain the different responses the BS can generate to bring the system to a consistent state. (6 marks)
