5 Reliable delivery and Handshaking (15 points) Suppose Alice and Bob wish to communicate through a reliable delivery protocol that uses sequence num- bers and cumulative acknowledgment numbers in their packets that are similar to TCP's. Suppose Alice initiates 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 "NOr, ollowing it up by esplaining 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+15-3 points) 4. Can Alice transmit data in this ACK packet? Write "YES" or "NO". (1 point) 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 out to Alice and uses his full window's worth of packets each round-trip 7
