Software-Defined Network is an emerging paradigm that has evolved to address weaknesses in traditional networks in recent years. The idea behind this technology is to separate the control plane from the data plane, making network management and programmability more flexible and easier. This paper aims to investigate the influence of the increasing number of pings (100-500) on two network platforms: software-defined network and traditional network. Ping is defined as a simple Internet application that lets users check whether a specific target IP address is available and able to receive requests in computer network administration. Moreover, Ping is also used as a diagnostic tool to make sure the host machine that the user is attempting to contact is up and running. The simulation was carried out using Mininet (the Mininet graphical user interface) to set up hosts and switches. Results revealed that software-defined networks improved the total number of packets received (22-40) %, average round-trip time (56-64) %, and reduced the total number of dropped packets (83-58) %. Therefore, it can be concluded that software software-defined network paradigm may be adopted for the network infrastructure’s growing demand.
