Question: Think about a TCP sender and receiver.
Suppose bytes 0 .. 99 have been sent, received, and acknowledged (the sender has received ack's for them). Suppose the sender sends the following segments (of 20 bytes each): 100, 120, 140, 160, 180, 200.
Assume these segments are received in the following order:
140
160
120
100
180
200
Demonstrate me what ack is generated by the receive after receiving each of these segments. Will the sender retransmit a packet? Which one and when?
