Suppose a TCP connection, with window size 1, loses every other packet. Those that do arrive have RTT = 1 second. What happens?

What happens to TimeOut? Do this for two cases:

(a) After a packet is eventually received, we pick up where we left off, resuming with EstimatedRTT initialized to its pretimeout value, and TimeOut double that.

(b) After a packet is eventually received, we resume with TimeOut initialized to the last exponentially backed-off value used for the timeout interval.

In the following four exercises, the calculations involved are straightforward with a spreadsheet.
