To meet these requirements, it is essential to find the optimal transmission path within the network. In this paper, we construct a network in the form of Software-Defined Network (SDN), and through it, we enable control with a global perspective on the network. Next, we propose an algorithm to explore the optimal path for time sensitive traffic transmission using genetic algorithms (GA). In addition, it was confirmed that this algorithm showed very high efficiency in terms of time while having the level of accuracy of the actual optimal path derived by searching through dynamic programming (DP). Finally, when the path found through this algorithm is applied to the SDN topology, it was confirmed that the jitter, packet loss rate, and delay are significantly lower than that of the transmission path provided by the controller." }
