Assume you are using Selective Repeat with a window size of 5 slots, sequence numbers ranging from [0,20] and that the sender side application has at least 20 packets work of data ready to send to the transport layer. Consider now that the sender has sent out a full window of packets, with sequence numbers 0 thru 4, but packet 3 is lost. What would be the sequence of ACKs received by the sender before the timer for Packet 3 expires, assuming it is set for an extra long time? ACKO, ACK1, ACK2, ACK4, ACK5, ACK6, ACK7, ACK 8 ACKO, ACK1, ACK2, ACK2, ACK2, ACK2, ACK2 ACKO, ACK1, ACK2, ACK4, ACK5, ACK6, ACK7 ACKO, ACK1, ACK2
