[e2e] TCP Timeouts and TripleDupACK

[Borman, David]

TCP runs over IP, which is unreliable, so you'll always need a mechanism to detect lost packets.  In TCP that is done via timeouts to detect the lack of response to data packets; which handles either the outbound data or returning ACK getting lost.
