The table below shows the sequence of events that happen during a TCP connections between two hosts A and B, when A opens a connection to B, sends a single data segment, and then closes the connection. Order the events as they occur as part of the connection, and indicate which host or hosts they occur at. Order A B Event Send an ACK segment Do the rest of the data exchange Close the connection Send an ACK segment Send a FIN segment Send a SYN segment Send a FIN segment Send a SYN-ACK segment Enter the TIME-WAIT state Send an ACK+DATA segment Close the connection (b) (2 points) What is the purpose of a SYN cookie? (c) (2 points) What is the advantage of TCP Selective Acknowledgements (SACK) over the original cumulative acknowledgement scheme? (d) (2 points) What is silly window syndrome? (e) (4 points) Multicast is a protocol designed to allow the same data to be broadcast between computers on the same multicast group. Each time a host in the group sends a datagram to the multicast group, the network routers ensure that that data- gram is sent to all members of the group. Considering the SEQ/ACK methods used by TCP/IP to guarantee reliable delivery of data between nodes, what fundamental issues will be created when trying to implement reliable multicast to large groups of hosts?
