Problem 6 Hosts A and B has established a TCP connection, and Host B has received from A all bytes up to byte 200. Suppose Host A sends three segments to Host B, containing 100, 60, 120 bytes of data, respectively. Assume that out-of-order packets are buffered by the receiver. Give the sequence number of each segment sent by A and the acknowledgement number of each segment received by A, in each of the following scenarios: a) All transmissions are in-order and successful. Host A Host B Pkt 1 Timeout interval Pkt 2 Ack Pkt 3 Ack Ack (a) successful b) The first segment sent by A is lost. Host A Host B LPkt 1 Timeout interval Pkt 2 Pkt 3 Ack Ack Ack (b) lost packet c) The first acknowledgement sent by B is lost. Host A Host B Pkt 1 Timeout interval Pkt 2 Pkt 3 Ack Pkt 1 Ack Ack (c) lost ACK d) The second segment sent by A arrives after the third segment. Host A Host B Pkt 1 Timeout interval Pkt 2 Ack Pkt 3 Ack Timeout interval Ack (d) out-of-order packet
