Abstract: The current surge in emerging technologies in networking has significantly improved people's lives by providing convenience and enjoyment. However, these technologies pose higher demands on network data processing and require a balance between security and stability. To meet the current load balancing needs, traditional network architectures use the link modules and overlook the server modules to improve the efficiency of the network. This study proposes the path-server traffic scheduling (PSTS) algorithm. It introduces server modules and utilises the software-defined network (SDN) paradigm with modular functionality implementation through the RYU controller. The procedure includes assessing performance metrics, specifically, impact factors at link and server levels. The algorithm ranks and filters each link and server by calculating weights based on previously obtained impact factor information, providing support for optimal traffic scheduling. Simulation results attain superior average bandwidth utilisation and reduced average transmission latency compared to the existing algorithm.

Keywords: SDN; software-defined networking; traffic scheduling; load balancing; path-server traffic scheduling algorithm.
