Question 4: (2.5 points) Consider that Host A and Host B have set up a TCP connection. During the handshaking, Host A set its initial sequence number to 4000 and Host B set its initial sequence number to 0. Host B also reports that its receive buffer can hold a total of 4096 bytes. We will neglect Host A's receive buffer. The table below provides the flow of packets transmitted between Hosts A and B. Fill in the table below and assume that an ACK is sent back immediately upon receiving data, i.e. we are not implementing the delayed ACK of TCP Host B Host A Seq: ??, d:1000, Ack:?? Seq: ??, d:100, Ack:??, rwnd:?? Seq: ??, d:800, Ack:?? Seq: ??, d=200, Ack:?? rwnd:?? Flow direction Payload size Sequence # Ack # swnd A B 1000 100 800 200
