Question: Host A and B are directly connected using a 1000 Mbps link that many other hosts use to transport data. Host A is sending Host

Host A and B are directly connected using a 1000 Mbps link that many other hosts use to transport data. Host A is sending Host B an enormous file over the 1000 Mbps link. Host A can send at a rate of 100 Mbps, but host B can receive data at a maximum rate of 50 Mbps. After a few seconds, Host A receives two ACKs with duplicate values from Host B. The value for the rwnd field in the first ACK is 4380 and 5840 in the second ACK.

A- What can you deduce about the reason Host A is receiving duplicate ACKs?

B- Why did the rwnd field increase?
