High Speed Data Transmission in Long Fat Network

The performance of Internet is heavily influenced by the behaviour of TCP. This is because TCP is the most commonly used transport protocol. The performance of TCP deteriorates right from startup phase of TCP connection. The optimum initial window size for sending data is determined during the slow start phase, while the congestion avoidance phase is for the management of a steady behaviour of TCP connection. Slow start is a poor performer in all networks including wireless and high speed networks referred to as Long Fat Networks (LFN). This is because slow start is very slow at the connection setup and its exponential increase leads higher packet loss rate. There are numerous faster startup schemes developed to overcome shortfall of slow start and improve performance during TCP connection setup but the regular TCP itself has never been efficient. Fibonacci TCP is developed to solve disadvantage in regular TCP. However, how these fast startup schemes impacts on fibonacci TCP was not well known.
