1. Suppose at time 0, the initial estimate y(0) of the RTT equal to the true value ro. But immediately after time 0, the true value of RTT for the connection increases to R and remains at that R. for the remainder of the connection. You may assume R » To- Suppose that the TCP retransmission timeout value at step n, RTO (n), is set to By(n). Calculate the number of RTT samples before we can be sure that there will be no spurious retransmissions (i.e., premature timeout). Express the number as a formula using parameters: To, a, B. R.
