Reliable delivery and Handshaking (15 points) uppose Alice and Bob wish to communicate through a reliable delivery protocol that uses sequence num- ers and cumulative acknowledgment numbers in their packets that are similar to TCP's. Suppose Alice itiates a connection to Bob, sending a SYN packet that has a (packet-based) sequence number 46 1. Suppose Bob responds to Alice with a packet that has both SYN and ACK flags set, with a (packet- based) sequence number 25. What is the (packet-based) ACK number on Bob's SYN-ACK packet? (2 points) 2. Can Bob transmit data in his SYN-ACK packet? Say "YES" or "NO, following it up by explaining why or why not. (1 +2- 3 points) 3. As a response to Bob's SYN-ACK, Alice sends out an ACK packet. What are the (packet-based) sequence and ACK numbers on Alice's ACK packet? (1,5 + iS-3 points) 4. Can Alice transmit data in this ACK packet? Write "YES" or "NO". (1 point) uppose Alice and Bob converse using a go-back-N protocol with a fixed window size of 10 packets once Alice's ACK has been sent out. Consider only Bob's data transmissions to Alice. Bob has an window's worth of packets each round-trip infinite stream of data to send out to Alice and uses his full 7
