Consider the figure below, which plots the evolution of TCPs congestion window at the beginning of each time unit(where the unit of time is equal the RTT).

The initial value of cwnd is 1 and the initial value of ssthresh is 8.

1) Give the range of times (as StartTime-EndTime) at which TCP is slow start:

2) Give the range of times (as StartTime-EndTime) at which TCP is in congestion avoidance:

3) Give the time at which TCP is in fast recovery at the start of a time slot, when the flight of packets is sent:

4) Give the times as which the first packet in the sent flight of packets is lost that was detected via timeout:

5) Give the times at which the first packet in the sent flight of packets is lost that was detected via triple duplicate ACKs:

6) Give the times at which the value of ssthresh changes, and give the new value of ssthresh:

- Changed at ........... and the new ssthresh =

- Changed at ........... and the new ssthresh =

- Changed at ........... and the new ssthresh =
