4. Assume a TCP connection is setup between hosts A and B. At some point in time we capture the following exchange of segments: first; host A -> B, Seq. # = 148, Ack # = 211, header length = 20, rwnd = 4000; then a response from host B -> A, Seq #= 212, ACK# = 248, header length = 20, rwnd = 2000. Is there a mistake in any of the field values of these segments? Why? (12 pts.)
