Software-defined routing in convergent LTE/WiFi networks

This paper describes routing programming solutions in the Mininet virtualized software-defined network. There are two challenges in implementing SDN into convergent LTE/WiFi network. The first challenge is measuring the QoS parameters by means of external network load monitoring systems. The second challenge is disuse of QoS-based routing by vendors because of high requirements of real-time load balancing algorithms to the pass-through latency. A router configuration method is proposed in this paper to address these issues. The solution to the aforementioned issues may be the routing configuration with network coefficient matrix with proved experimentally effectiveness. The elaborated SDN controller in Java 9 times surpasses standard routing methods in terms of the average peak signal-to-noise ratio. The conclusion contains the prospective trends of development within the scope of the inquiry.
