Optimising service quality and network efficiency in legacy networks by integrating SDN and broadband

Oleksandr Pidpalyi

The study aimed to develop an empirical model for optimising the quality of service (QoS) and improving the efficiency of telecommunications networks by integrating software-defined networking (SDN) and broadband Internet access technologies. The study employed simulation modelling, scenario analysis and analytical models with the use of modelling tools. The main findings of the study highlighted the significant potential of integrating SDN and broadband technologies to improve the QoS and efficiency of telecommunications networks. SDN concepts were demonstrated, which provide centralised network management and flexibility in configuration, as well as broadband access, which offers high data rates and improved bandwidth. The role of each network element, including routers, switches and controllers, and their impact on network efficiency was identified. An analysis of the interaction of SDN with broadband access networks has shown that the use of such networks allows optimising routing, load balancing and traffic management, which helps to improve network speed and reliability. QoS metrics demonstrated that the integration of different technologies leads to significant improvements in bandwidth, packet loss, latency and latency variability. In general, the network model showed the effectiveness of SDN and broadband integration in optimising network performance and QoS, and a review of network modelling methods showed that the use of simulation tools allows for a detailed assessment of the effectiveness of technology integration and confirmation of their positive impact on network performance. Thus, results confirmed that the integration of SDN and broadband technologies significantly improves the efficiency of telecommunications networks, which indicates the effectiveness of new technologies in increasing the overall performance of networks
