Effect of TCP-window size on distribution of time slots between traffic packets in software-defined SDN networks

This work considers effect of TCP-window size on the numerical characteristics of time slots between packets. Here we researched first three initial time slot moments due to developed mathematical model utilizes them. Researches were performed on virtual experimental setup installed over physical servers by OpenNebula platform. We considered two cases including software-defined network supporting OpenFlow open protocol and conventional network without it. The first one is performed with POX controller and physical switch. Here we utilize software products tcpdump for traffic capture and Iperf for traffic generation. This work presents script providing traffic generation initiation process automation. Obtained results were imported to MS Excel. Then moment characteristics are evaluated by well-known mathematical statistics formulas.
