*This presentation is about a rewriting/extension of A. Theodore Markettos, P. J. Fox, S. W. Moore, A. W. Moore, "Interconnect for comodity FPGA clusters: standardized or customized?", \textit{2014 24th International Conference on Field Programmable Logic and Applications (FPL)}, 2014, pp. 1-8. It has been written in the course of the seminar "Scientific Writing" (193.052) at TU Vienna, which shall help undergraduate students to get first experience in the art of scientific writing.
