TCP and UDP deployment in environment with high delay and high bit error rate

Nowadays implementation of TCP and UDP protocols offer high speed and reliability on data links. Especially TCP implementations offer high speed rates, employing sliding window and data acknowledgement in TCP protocol. On the contrary, UDP offers different options and has other advantages and disadvantages. But in certain environment, especially with high delay and high bit error rate, these protocols have different qualities and behave in different way. Our goal was to investigate them and propose possible solutions to optimize overall performance.
