Question

By comparing the time out mechanism used in TCP to that used in a data link layer protocol, outline why it is necessary for the TCP timeout mechanism to implement an adaptive timeout duration

Answer 1

When there are network flows within the wireless link that experience prolonged poor transmission it can impact on the network, leading to the stalling of the source while waiting for the arrival of ACKS, due to the filling of the TCP source congestion window. More time is lost as the source waits for a timeout to be caused by the expiration of the RTO timer which results in lower efficiency and network throughput by the TCP that requires an adaptive timeout duration to be implemented
