Recall the simplified TCP throughput equation TCP throughput 1.22. MSS RTT L (a) Provide a derivation of this equation utilising a figure. Include a description of each term of this equation and example values (including units). [6 marks] (b) What does this equation imply for networks of 10 Gbit/s throughput. [3 marks] (c) What important TCP congestion behaviour does this equation not capture? [3 marks] (d) CUBIC is commonly used as an alternative to classic AIMD TCP congestion control. (2) With the aid of a diagram showing window size over time, compare how CUBIC differs from classic AIMD TCP congestion control. [6 marks] (ii) With reference to the diagram used in part (d) (i) discuss how the CUBIC approach improves performance for a flow on a link with very large bandwidth delay products. [2 marks]
