Q2) The window size (N) is 2 . The server is going to send you 5 packets. pktl will be lost when it's sent the first time. Write the messages into boxes below, based on Selective Repeat protocol. Rulel: pkt\# indexing starts from 0 . Rule2: You must use the exact terms as shown in Figure 3.26 from the book. Rule3: One box must have only one message. A comma, space, round brackets must be used when necessary. On Selective Repeat: 1) sending/receiving ACK is a separate line of message. 2) receiving out-of-order packets and buffering them must be done in a single line of message. 3) when buffered packets are being delivered, separate this message from sending ACK and receiving the packets. So, when the lost packet arrives, receive it in the 1st line, but deliver it on the 2nd line, with other buffered packets. 4) window full is mentioned only once, upon the very first occurrence. 5) we stop when the ACK of the last received packet was sent from the Receiver. It's not required to receive them on Sender's side. 6) "nothing sent" doesn't have to be mentioned. 7) timeout message must be written in a separate line of message. Resending must follow it on the next line. 8) if a single packet is received and there are no buffered packets at that moment, you must mention that it's delivered, on the same line. 9) (repetition of 3rd) if a single packet is received, but there are some buffered packets in memory, you should receive that packet in the first line, and then deliver that packet with the buffered ones on the next line
