QoS MANAGEMENT IN SOFTWARE DEFINED NETWORKS FOR IoT ENVIRONMENT: AN OVERVIEW

Software Defined Networks (SDN) offer a new architecture and different approach to the management of traffic and network resources. Unlike traditional networks, SDN separates control and data planes and enables centralized network management. Forwarding devices are programmable, network statistics are monitored and behavior adjusted to current traffic conditions. SDN is an answer for meeting the QoS (Quality of Service) demands of environments such as IoT (Internet of Things). This paper provides an overview of contemporary approaches in optimizing such complex scenery, and present-day mechanisms for balanced and efficient use of network capacities, ensuring QoS through traffic-aware routing and dynamically adaptive rules. Key new ideas were identified in optimizing the management of the SDN-IoT network. Ultimately, room for future research has been identified and the need to create a new comprehensive model tailored to the specificities of the SDN-IoT environment has been addressed.
