Quiz 3 1. What is the minimum amount of available buffer space sent to the receiver for the entire trace? Answer: b. Minimum amount of buffer space: 29200. 2. Are there any retransmitted segments in the trace file? If there are retransmissions, why is that? And if there are no retransmissions, why is that? Answer: a. There are segments that retransmit in the trace file due to congestion on the packet so that the server is full. 3. How much of the receiver's data is specifically ACK? Can you identify cases where the receiver gives an ACK every time another segment is received? (See the print book Computer Networking: A Top Down Approach 6th edition by Kurose Ross on Table 3.2 page 247). Answer: a. The number of receivers specifically performing ACKs is 204, in-order segment arrivals with the expected sequence number. One other in-order segment awaits ACK transmission lOMoARcPSD|26370826 4. What is the throughput for the TCP connection in one trace file? Explain how you calculated the throughput! Answer: a. L/R = 169315 / 7.043 = 24.0401817 bytes/s = 24 Kbytes/s
