Exercise for the reader: If a TCP connection will time out and abort the
connection if it receives no ACK to T retransmissions of a segment X, given
that it has N total segments to transmit, derive the equation f which gives
Pc = f(Pp, T, N), where Pc is the probability of the successful completion of
the tranmssion, and Pp is the probability of the loss of any individual
packet.
