Which version of the TCP is running? Provide an explanation of how you have obtained your answer. b. How many losses have been detected during the first 30 transmission rounds? When are these losses detected? Are these losses due to timeout or triple duplicate ACK? Explain. c. What is the value of ssthresh at transmission round 1 and at transmission round 17? How did you find these numbers? Explain. d. How many segments have been transmitted in the first 4 transmission rounds? Show your work. e. At which transmission round segment 70 has been transmitted?
