Analytical model for software defined network considering memory node for routing rules

In this work a software defined network (SDN) is studied as a queueing network. The main point of the system is that the switch memory node, storing routing rules is modeled separately. The memory node impacts the distribution of the newly arrived packets among the other nodes. In this work we propose analytical and simulation model to analyze the performance of the considered network. Analytical model covers a simplified network case with one flow type, while simulation model let us analyze a general-case of SDN network segment with multiple flow types. © Springer Nature Switzerland AG 2020.
