Communication through computer networks and data networks became a part of our everyday life. The transport protocol TCP – and especially its congestion control mechanism - has played a key role in the success story and widespread adoption of the internet and has protected the network from collapse under heavy loads. However high-speed network segments and evironments became more and more commonplace nowadays and TCP cannot scale to utilize these resources fully and in a satisfactory manner. A bunch of new congestionc control algorithms has been developed to meet these challenges, however to analyze and predict the interaction between these different kind of mechanisms – especially in realistic network scenarios - is still a very hard problem til today. A new kind of transport mechanism is proposed, that is based on the abandon of classic congestion control algorithms. In a protocol like this, a new kind of rateless erasure control codes (the so called Fountain-codes) must play a very important role. Simulation always has been played a very important role int he analysis and study od communication networks. The topic of this thesis is the simulation of this new kind of protocol and of the TCP in the same scenarios.
