Consider the exchange of TCP segments between Hosts A and B shown in the figure below. The TCP connection establishment process is not shown. The figure depicts all segments exchanged between the two hosts (i.e. no other segments beyond those shown are exchanged). Host A sends two data segments (with sequence numbers 32 and c, respectively). Host B responds with an ACK for each segment (with sequence numbers a and e, respectively). The first ACK is lost, the second ACK is received by Host A. Host A Seq=32, ACK = 121, Data=389 bytes- Seq=c, ACK =d, Data=513 bytes Seq=g, ACK =h X Host B Seqa, ACK=b, data = 0 byte Seq e, ACK=f, data = 0 byte Host A transmits a third segment (with sequence number g) a few moments after receiving the ACK from Host B. You will need to figure out whether this segment is a retransmission of either of the two previously transmitted data segments or a fresh segment containing new data. Based on this, answer the following questions. Simply note the numeric answers in the space provided. No explanations are required. What is g? What is h?

Since the first ACK is lost Host A will not know that Host B has received the ... View the full answer
